• Regulatory Compliance: Both parts maintain identical REACH Unaffected status and EAR99 classification. The substitute achieves ROHS3 compliance, meeting current environmental standards
• Functional Equivalence: Both parts are blue InGaN LEDs in 4mm form factors designed for LED indication applications, with compatible electrical characteristics
• Manufacturer Continuity: Both parts are manufactured by Broadcom Limited, ensuring consistent quality and reliability standards

Frequently Asked Questions (FAQ)

Q: Why is the QLMP-LB87-UVCZZ obsolete? A: The QLMP-LB87-UVCZZ has reached end-of-life status. Broadcom Limited has transitioned this product line to the HLMP-LB71-TUBDD, which provides equivalent functionality with active production support.

Q: Are the QLMP-LB87-UVCZZ and HLMP-LB71-TUBDD electrically compatible? A: Both parts are blue LEDs with 470nm dominant wavelength designed for LED indication applications. The HLMP-LB71-TUBDD operates at 3.1V forward voltage with 20mA test current, which are standard parameters for blue InGaN LEDs in this category.

Q: What are the key differences between these parts? A: The primary differences are product status (obsolete vs. active), packaging designation (4mm vs. 4mm Oval), lens characteristics (diffused transparency, domed top), and compliance certifications (ROHS3 compliance for the substitute). Both maintain identical regulatory classifications and wavelength specifications.

Q: Can I use the HLMP-LB71-TUBDD as a direct replacement in existing designs? A: The HLMP-LB71-TUBDD is the manufacturer-recommended substitute. Both parts are through-hole mounted 4mm form factor LEDs. Verify that your PCB layout accommodates the 4mm oval package dimensions and that the diffused lens transparency meets your optical requirements.

Q: What is the MSL rating difference? A: The original part lists MSL as Not Applicable, while the substitute (HLMP-LB71-TUBDD) has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: Are there any compliance concerns with substitution? A: No. Both parts maintain REACH Unaffected status and EAR99 classification. The substitute achieves ROHS3 compliance, which exceeds the requirements of the original part and ensures compatibility with current environmental regulations.
