Frequently Asked Questions (FAQ)

Q: Why is the QLMP-LB78-STBDD obsolete? A: The QLMP-LB78-STBDD has reached end-of-life status. Broadcom Limited has transitioned this product line to active alternatives such as the HLMP-LB71-TUBDD.

Q: What are the key differences between QLMP-LB78-STBDD and HLMP-LB71-TUBDD? A: The primary differences are product status (obsolete vs. active), specified electrical parameters (the substitute provides 3.1V forward voltage and 20mA test current), and color specification (blue 470nm wavelength for the substitute). Both parts maintain equivalent regulatory compliance and moisture sensitivity ratings.

Q: Can I use HLMP-LB71-TUBDD as a direct replacement? A: The HLMP-LB71-TUBDD is the manufacturer-recommended substitute. Compatibility depends on your specific circuit design requirements, particularly forward voltage and current specifications. The substitute provides detailed electrical parameters (3.1V, 20mA) that should be verified against your application requirements.

Q: What is the packaging difference? A: The QLMP-LB78-STBDD packaging is not specified in available data. The HLMP-LB71-TUBDD is supplied in Tape & Box (TB) packaging with a 4mm oval through-hole configuration.

Q: Are the regulatory certifications equivalent? A: Yes. Both parts share identical REACH Unaffected status, EAR99 ECCN classification, and 8541.41.0000 HTSUS code. The substitute additionally carries ROHS3 Compliant certification.

Q: What is the inventory situation? A: The original QLMP-LB78-STBDD has 813 pieces in stock. The recommended substitute HLMP-LB71-TUBDD has 947 pieces available, providing adequate supply for new designs and production transitions.
