Engineering Selection Recommendations

HSMH-H150 (Broadcom Limited - Active Status)

This substitute is manufactured by the same supplier as the main part and maintains active product status, ensuring long-term availability. Forward voltage increases from 1.8V to 2.1V, requiring circuit design verification for current-limiting resistor adjustment. Luminous intensity decreases to 7.2mcd, which may impact visibility in high-ambient-light applications. Identical lens geometry and viewing angle support direct mechanical substitution. MSL rating remains 2A (4 Weeks), maintaining equivalent moisture handling requirements.

QTLP650D7TR (onsemi - Obsolete Status)

This substitute provides comparable luminous intensity at 15mcd and forward voltage of 1.9V, minimizing circuit redesign requirements. Wavelength-dominant shifts to 645nm within acceptable red spectrum range. Viewing angle reduces to 160°, acceptable for most indicator applications. Height increases to 1.30mm, requiring PCB layout verification for clearance. MSL rating improves to 1 (Unlimited), reducing moisture sensitivity concerns. Obsolete status limits long-term procurement viability.

Frequently Asked Questions (FAQ)

Q: Can HSMH-H150 be used as a direct drop-in replacement for HSMH-C150?

A: Mechanical compatibility is supported through identical lens geometry and 1206 package dimensions. Electrical compatibility requires circuit adjustment due to forward voltage increase from 1.8V to 2.1V. Current-limiting resistor values must be recalculated to maintain 20mA test current. Luminous intensity reduction to 7.2mcd may require application reassessment for visibility requirements.

Q: What are the key differences between HSMH-C150 and QTLP650D7TR?

A: Both parts maintain red diffused lens configuration and 1206 package footprint. QTLP650D7TR offers improved moisture sensitivity (MSL 1 vs. 2A) and comparable luminous intensity (15mcd vs. 17mcd). Forward voltage differs by 0.1V (1.9V vs. 1.8V). Viewing angle reduces from 170° to 160°. Height increases from 1.10mm to 1.30mm, requiring PCB clearance verification.

Q: Are there packaging differences between the substitute parts?

A: HSMH-C150 is supplied in Cut Tape (CT) & Digi-Reel® packaging. HSMH-H150 is supplied in Tape & Reel (TR) format. QTLP650D7TR packaging format is not specified in available data. Packaging selection depends on assembly process requirements and volume considerations.

Q: How does the wavelength shift from 639nm to 645nm affect application performance?

A: Both wavelengths fall within the red spectrum range and maintain 660nm peak wavelength. The 6nm dominant wavelength shift is imperceptible to human vision in indicator applications. Color appearance remains consistent with standard red LED indicators.

Q: What compliance considerations apply to substitute selection?

A: HSMH-C150 maintains ROHS3 compliance and REACH Unaffected status. Both substitute parts carry REACH Unaffected designation. RoHS compliance status for HSMH-H150 and QTLP650D7TR is not specified in available data and must be verified through manufacturer documentation before final selection.
