Frequently Asked Questions (FAQ)

Q: Why is the QSME-C270 classified as obsolete?

A: The QSME-C270 has been discontinued by Broadcom Limited and is no longer manufactured. Existing inventory is limited to 1192 pcs. The HSME-C265 represents the current production equivalent.

Q: What are the key differences between QSME-C270 and HSME-C265?

A: The primary differences are product status (obsolete vs. active), packaging format (unspecified vs. Tape & Reel), and complete specification documentation. Both share identical manufacturer, product category, and regulatory classifications.

Q: Is HSME-C265 a direct pin-for-pin replacement?

A: Pin compatibility cannot be confirmed from the provided specifications. The HSME-C265 uses a 1305 (3412 Metric) surface mount package with bottom entry mounting. Physical and electrical integration must be validated against the original circuit design.

Q: What is the packaging format of HSME-C265?

A: HSME-C265 is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount LED applications. This differs from the unspecified packaging of the obsolete QSME-C270.

Q: Are there any compliance concerns with substituting HSME-C265 for QSME-C270?

A: No compliance concerns exist. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. HSME-C265 is RoHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: What is the moisture sensitivity level of HSME-C265?

A: HSME-C265 has a Moisture Sensitivity Level (MSL) rating of 2A, indicating a maximum floor life of 4 weeks after bag opening. Proper storage and handling procedures must be followed to maintain component reliability.

Q: What are the optical specifications of HSME-C265?

A: HSME-C265 is a green LED with a dominant wavelength of 572nm and peak wavelength of 570nm. It provides 50mcd brightness at 20mA test current with a 150° viewing angle and colorless clear lens.

Q: What is the forward voltage requirement for HSME-C265?

A: HSME-C265 operates at a typical forward voltage (Vf) of 2.1V with a test current of 20mA. Circuit design must accommodate this voltage specification for proper LED operation.
