QTLP650D7TR Equivalent & Substitute Parts

Part Overview

The QTLP650D7TR is a red diffused LED indicator manufactured by Everlight Electronics Co Ltd, designed for surface mount applications in the 1206 (3216 Metric) package format. This component operates at a forward voltage of 1.9V with a test current of 20mA, delivering 15 millicandela at a dominant wavelength of 645nm. The part is currently in active production status with ROHS3 compliance and is suitable for standard indication applications requiring diffused red light output.

Substitute parts are identified based on matching mechanical package dimensions, electrical operating parameters, mounting type, and compliance certifications. Alternative components may be necessary due to supply chain availability, inventory levels, or specific application requirements within the defined electrical and mechanical tolerance ranges.

Parameter Comparison

Engineering Selection Recommendations

QTLP650D7TR (Primary Selection): The QTLP650D7TR is the recommended primary component for new designs and ongoing production. This part maintains active product status with current manufacturing support from Everlight Electronics Co Ltd. The component is ROHS3 compliant and carries standard moisture sensitivity level MSL 3 (168 Hours). Current inventory availability is 877 pieces.

HSMH-C150 (Substitute Selection): The HSMH-C150 from Broadcom Limited is a qualified substitute for applications where the QTLP650D7TR is unavailable. This part is ROHS3 compliant and meets all mechanical and electrical compatibility requirements. However, the HSMH-C150 carries obsolete product status, indicating discontinued manufacturing. The substitute exhibits a lower maximum height (1.10mm versus 1.30mm), wider viewing angle (170° versus 140°), and slightly higher luminous intensity (17mcd versus 15mcd). Inventory availability is significantly higher at 32,300 pieces. The moisture sensitivity level is MSL 2A (4 Weeks), which is more stringent than the primary part.

Compliance Considerations: Both parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring regulatory equivalence for export and supply chain purposes.

Frequently Asked Questions (FAQ)

Q: Can the HSMH-C150 be used as a direct replacement for the QTLP650D7TR in existing designs?

A: The HSMH-C150 is mechanically and electrically compatible within the defined parameter ranges. Both components use the 1206 (3216 Metric) package with identical footprints and mounting requirements. The forward voltage difference (1.8V versus 1.9V) is within typical circuit tolerance. However, the substitute exhibits higher luminous intensity (17mcd versus 15mcd) and a wider viewing angle (170° versus 140°), which may affect visual appearance in the final application. Verification of circuit performance is necessary if brightness consistency is critical.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Forward voltage is 0.1V lower on the HSMH-C150; (2) Luminous intensity is 2mcd higher; (3) Viewing angle is 30° wider; (4) Maximum height is 0.2mm lower; (5) Product status differs (Active versus Obsolete); (6) Moisture sensitivity level differs (MSL 3 versus MSL 2A). All other parameters including package, mounting type, color, lens transparency, and wavelength characteristics are equivalent.

Q: Are there any supply chain considerations when selecting between these parts?

A: The QTLP650D7TR is the recommended choice for new designs due to active product status and ongoing manufacturing support. The HSMH-C150 is obsolete and represents legacy inventory. While current stock levels for the HSMH-C150 are higher (32,300 pieces), this inventory is finite and will not be replenished. For long-term production requirements, the QTLP650D7TR is the appropriate selection.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both the QTLP650D7TR and HSMH-C150 are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. Both parts are suitable for applications requiring regulatory compliance in these categories.

Q: What is the impact of the different moisture sensitivity levels?

A: The QTLP650D7TR carries MSL 3 (168 Hours), while the HSMH-C150 carries MSL 2A (4 Weeks). MSL 2A is more stringent and requires more careful handling during storage and assembly. The HSMH-C150 has a shorter allowable time at elevated humidity before soldering. This difference may affect supply chain logistics and assembly procedures.

Q: Can the higher brightness of the HSMH-C150 affect circuit design?

A: The HSMH-C150 delivers 17mcd compared to 15mcd for the QTLP650D7TR at identical test current (20mA). This 2mcd difference represents approximately 13% higher luminous intensity. In applications where brightness is visually critical or where the LED brightness is used as a feedback indicator, this difference may be perceptible. Circuit design parameters such as current-limiting resistor values remain unchanged, as both parts operate at the same test current.
