LED Component Technical Datasheet - Revision 2 - Lifecycle Phase - English Technical Document

1. Product Overview

This technical datasheet provides comprehensive information regarding the lifecycle management and revision control for a specific electronic component, likely an LED or similar optoelectronic device. The core focus of this document is to establish a clear and traceable record of the product's revision history, ensuring consistency and reliability in manufacturing and application. The document's primary function is to serve as a definitive reference for the component's approved state, indicating that Revision 2 is the current and active version intended for production and use. The target market includes electronics manufacturers, design engineers, and procurement specialists who require certified and version-controlled components for their assemblies.

2. Technical Parameters and Lifecycle Data

The document presents a structured set of metadata fields that define the component's status within its product lifecycle. This data is critical for quality assurance and supply chain management.

2.1 Lifecycle Phase

The LifecyclePhase is explicitly stated as Revision. This indicates the component is in a state of controlled update or correction from a previous version. It is not an initial release nor an end-of-life notice, but a maintained and active product iteration.

2.2 Revision Number

The revision number is specified as : 2. This denotes that this document and the component it describes are the second major revision. Understanding the revision history is essential for identifying changes in specifications, performance, or manufacturing processes compared to Revision 1 or earlier versions.

2.3 Expired Period

The Expired Period is listed as Forever. This is a significant declaration meaning that this revision of the component has no planned obsolescence date from the perspective of this document's validity. It implies the manufacturer intends to support this revision indefinitely, or at least for the foreseeable future, barring any unforeseen technical or commercial reasons for change.

2.4 Release Date

The Release Date is precisely timestamped as 2013-10-07 11:48:35.0. This provides an exact historical record of when Revision 2 was formally issued and approved for production and distribution. This timestamp is crucial for auditing, tracking fielded units, and correlating component versions with assembly dates.

3. In-Depth Analysis of Document Structure and Implications

The repetitive presentation of the same data block throughout the provided content suggests this may be a header or footer repeated on each page of a longer PDF document. The core informational block "LifecyclePhase:Revision : 2\nExpired Period: ForeverRelease Date:2013-10-07 11:48:35.0" is the consistent element. The presence of special characters like "●" (black circle) and "・" (katakana middle dot) likely serve as visual markers, possibly denoting list items or section separators in the original document's formatting. The series of dots (・) indicates an ellipsis or continuation, implying there is more content in the original document that is not shown in this excerpt.

4. Performance and Reliability Interpretation

The declaration of "Forever" as the Expired Period, combined with a defined Release Date, creates a framework for assessing component longevity and support. It suggests a mature product where the design and process are stable. For engineers, this translates into predictability for long-term projects and maintenance cycles. The specific timestamp allows for precise calculation of the component's age in the market, which can be a factor in reliability analysis and mean time between failures (MTBF) estimations for systems using this part.

5. Mechanical and Packaging Considerations

While specific dimensions (LxWxH), voltage, power, or color are not detailed in the provided excerpt, a full datasheet for an LED component would typically include this information in subsequent sections. The lifecycle data provided forms the foundational header for such detailed specifications. It guarantees that any mechanical drawing, footprint diagram, or packaging specification referenced later in the document is unequivocally associated with Revision 2. Any change in physical dimensions, pad layout, or polarity marking would necessitate a new revision number, making this header data the key to change control.

6. Assembly and Process Guidelines

The revision control directly impacts assembly processes. Manufacturing instructions, including Surface Mount Technology (SMT) reflow profiles (pre-heat, soak, reflow, cooling temperatures and times), handling precautions, and storage conditions (often moisture sensitivity level, or MSL), are defined for a specific revision. Using Revision 2 ensures that the assembly process is aligned with the component's validated manufacturing tolerances and material properties, preventing defects like tombstoning, solder cracking, or thermal damage.

7. Ordering and Traceability Information

The combination of LifecyclePhase, Revision number, and Release Date is integral to the component's ordering code and traceability. A complete part number would embed the revision (e.g., -REV2). Labels on reels or packaging would include this data to prevent mixing of revisions in production. The "Forever" expired period simplifies inventory management, as there is no need to track a sunset date for this version, though it remains best practice to use the latest revision.

8. Application Notes and Design Integration

For design engineers, knowing the revision is critical when referencing electrical parameters such as forward voltage (Vf), luminous intensity, viewing angle, or spectral characteristics. Any performance curve—Current vs. Luminous Flux (IV curve), temperature derating graphs, or spectral power distribution charts—are valid only for the stated revision. Design calculations and circuit simulations must be based on the datasheet for Revision 2 to ensure accuracy and performance compliance in the final application, whether it be backlighting, indicators, automotive lighting, or general illumination.

9. Technical Comparison and Version Control

The primary differentiation highlighted here is between Revision 2 and its predecessor(s). The advantage of Revision 2 lies in its formal, released, and supported status. Potential improvements over Revision 1 could include corrected typographical errors in the datasheet, optimized binning criteria for color or flux, enhanced reliability data from extended testing, or minor process improvements that do not affect form, fit, or function but increase yield or consistency. A detailed change log would normally accompany a revision update to specify these differences.

10. Frequently Asked Questions (FAQs)

Q: What does "LifecyclePhase: Revision" mean?
A: It means the component is an updated version of a previously released product. The design is active, approved, and currently in production.

Q: Is a component with an "Expired Period: Forever" guaranteed to be available indefinitely?
A: While it indicates no planned end-of-life, availability can still be affected by raw material shortages, factory issues, or drastic market changes. "Forever" reflects an intention, not an absolute guarantee.

Q: Can I use Revision 1 and Revision 2 components interchangeably in my product?
A: Not without verification. Always consult the engineering change notice (ECN) or change log for Revision 2 to identify any differences that might affect performance, reliability, or assembly. If no changes affect form, fit, or function, they may be interchangeable, but the latest revision should be used for new designs.

Q: How do I ensure I am procuring Revision 2?
A: Specify the full part number including the revision suffix in your purchase orders and verify the labeling on received packaging.

11. Practical Use Case Scenario

Consider a manufacturer of industrial control panels that uses a specific LED as a status indicator. Their product has a 10-year support commitment. In 2015, they designed their panel using the component datasheet they had at the time. In 2023, they need to manufacture spare parts. By checking the lifecycle data on the current datasheet (Revision 2, released in 2013), they confirm that the same approved component version is still actively defined and supported. They can confidently re-order the part using the Revision 2 part number, ensuring identical performance and compatibility with their existing firmware and optics, thus fulfilling their long-term support obligations without re-qualification.

12. Fundamental Principles of Revision Control

Revision control is a systematic approach to managing changes to a product and its documentation. Its core principles include: Identification: Each version is uniquely numbered. Traceability: Changes from one version to the next are documented. Reproducibility: The exact product specification can be recreated at any point using the revision-specific documentation. Approval: Each revision is formally released after verification and validation. This process ensures quality, reduces errors, and facilitates continuous improvement while maintaining stability for end-users.

13. Industry Trends in Component Lifecycle Management

The trend in electronics is towards greater digitization and granularity in lifecycle data. While this document shows a static header, modern practices often involve linking datasheets to digital product passports or cloud-based platforms where lifecycle status, compliance certificates, and change notifications can be updated in real-time. There is also a growing emphasis on environmental and supply chain transparency, which may see future lifecycle phases include data on material sourcing, carbon footprint, and recyclability. The concept of "Forever" is also being challenged by faster innovation cycles, leading to more defined but shorter active lifecycles for many components, though long-life support remains critical for industrial, automotive, and medical applications.
