Frequently Asked Questions (FAQ)

Q: Why is the QLMD-LB93-TUC02 no longer available? A: The QLMD-LB93-TUC02 has reached obsolete status in Broadcom Limited's product lifecycle. Obsolete components are no longer manufactured or supported by the original manufacturer.

Q: Is the ALMD-LB38-TV002 a direct replacement? A: The ALMD-LB38-TV002 is the manufacturer-recommended substitute. Both parts are blue InGaN LEDs designed for discrete indication applications. Verification of mechanical fit and electrical performance within your specific circuit design is required before implementation.

Q: What are the key differences between these parts? A: The primary differences are product status (obsolete vs. active), packaging format (unspecified vs. Tape & Reel), MSL rating (1 vs. 2A), and documented electrical parameters (the substitute provides specified Vf, current, and luminous intensity values). The substitute includes a domed lens top and diffused lens transparency.

Q: Are there any compliance concerns with substitution? A: No. Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The substitute is ROHS3 compliant, meeting current environmental requirements.

Q: What is the MSL difference and does it matter? A: The original part has MSL 1 (unlimited moisture exposure tolerance), while the substitute has MSL 2A (4-week moisture exposure tolerance). This affects storage and handling procedures. MSL 2A requires controlled storage conditions and moisture barrier packaging.

Q: Can I use the ALMD-LB38-TV002 in existing designs without modification? A: Mechanical fit and electrical performance must be verified. The substitute provides specific electrical parameters (3.2V Vf, 20mA test current, 1090mcd) that should be confirmed compatible with your circuit design and PCB layout.
