Engineering Selection Recommendations

For Obsolete Part Replacement:

The HLMP-3950 is the designated substitute for the QLMP-3952-LM000. Selection rationale is based on:

1. Product Status Transition: The HLMP-3950 maintains Active status, ensuring continued availability and manufacturing support, eliminating supply chain risk associated with the Obsolete QLMP-3952-LM000.

2. Regulatory Compliance Continuity: Both components share identical REACH Unaffected status, EAR99 ECCN classification, and HTSUS code 8541.41.0000, ensuring no regulatory reclassification during substitution.

3. Functional Category Alignment: Both components are classified as LED Indication - Discrete with green color specification, maintaining functional equivalence in indication applications.

4. Manufacturer Consistency: Broadcom Limited manufactures both components, ensuring design philosophy and quality standards remain consistent across the substitution.

5. Environmental Compliance: The HLMP-3950 is ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting modern environmental and reliability standards.

Inventory Consideration:

Current inventory of 809 pieces of QLMP-3952-LM000 supports near-term production requirements. Transition planning to HLMP-3950 (10,400 pieces in stock) should commence to ensure uninterrupted supply for future production cycles.
