HSMH-C265 Equivalent & Substitute Parts

Part Overview

The HSMH-C265 is a red 639nm LED indication component manufactured by Broadcom Limited, designed for discrete surface mount applications with bottom entry mounting. This part is classified as obsolete, necessitating identification of equivalent substitute components for ongoing production and maintenance requirements. The HSMH-C265 delivers 17mcd luminous intensity at 1.8V forward voltage with a 170° viewing angle in a compact 1305 (3412 Metric) package.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the HSMH-C265 are identified based on the following critical parameters that determine functional equivalence:

Color and wavelength specifications (Red, 639nm dominant, 660nm peak) establish the primary optical characteristic. The viewing angle of 170° defines the light distribution pattern. Lens style (Rectangle with Flat Top) and transparency (Clear) specify the optical geometry. Mounting type (Surface Mount, Bottom Entry) and package classification (1305 Metric) determine physical and electrical interface compatibility. Test current (20mA) and forward voltage characteristics establish the electrical operating point.

The HSMH-H265 qualifies as a substitute based on matching color, dominant wavelength, peak wavelength, viewing angle, lens style, lens transparency, test current, and compliance certifications. Variations in forward voltage (2.1V vs. 1.8V) and millicandela rating (7.2mcd vs. 17mcd) represent functional differences that must be evaluated within the specific application circuit design.

Parameter Comparison

Engineering Selection Recommendations

The HSMH-H265 is the manufacturer-recommended substitute for the obsolete HSMH-C265. Both components maintain ROHS3 compliance, REACH unaffected status, and identical EAR99 export classification and HTSUS tariff codes, ensuring regulatory continuity.

The HSMH-H265 is currently in active production status, providing supply chain stability compared to the obsolete HSMH-C265. Both components share identical moisture sensitivity levels (2A, 4 Weeks), requiring equivalent handling and storage protocols.

Circuit design evaluation is required to assess the impact of the 0.3V forward voltage increase (1.8V to 2.1V) and the 57.6% reduction in luminous intensity (17mcd to 7.2mcd). These electrical and optical differences may necessitate modifications to current-limiting resistor values and brightness compensation in the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the HSMH-H265 be used as a direct pin-for-pin replacement for the HSMH-C265?

A: The HSMH-H265 shares the same mounting type (Surface Mount) and optical characteristics (Red, 639nm dominant wavelength, 170° viewing angle, Rectangle with Flat Top lens). However, the forward voltage difference (2.1V vs. 1.8V) requires circuit verification. Direct substitution without circuit modification may result in incorrect LED brightness or circuit malfunction.

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

A: The primary differences are forward voltage (HSMH-H265: 2.1V vs. HSMH-C265: 1.8V) and luminous intensity (HSMH-H265: 7.2mcd vs. HSMH-C265: 17mcd). The HSMH-C265 is obsolete while the HSMH-H265 is in active production. Both maintain identical wavelength specifications, viewing angle, lens style, and compliance certifications.

Q: Are there packaging differences between these parts?

A: The HSMH-C265 is supplied in Cut Tape (CT) & Digi-Reel® packaging, while the HSMH-H265 is supplied in Tape & Reel (TR) packaging. Both use the 1305 (3412 Metric) package classification. Packaging format differences may affect procurement and assembly processes but do not impact electrical or optical performance.

Q: What compliance certifications apply to both parts?

A: Both the HSMH-C265 and HSMH-H265 are ROHS3 compliant, REACH unaffected, classified as EAR99 for export control, and assigned HTSUS tariff code 8541.41.0000. Both components have identical moisture sensitivity levels (2A, 4 Weeks).

Q: How does the luminous intensity difference affect application suitability?

A: The HSMH-H265 produces 57.6% lower luminous intensity (7.2mcd) compared to the HSMH-C265 (17mcd). Applications requiring high brightness indication may require circuit redesign or alternative component selection. Applications with lower brightness requirements may accommodate the HSMH-H265 without modification.
