HSMH-C680 Equivalent & Substitute Parts

Part Overview

The HSMH-C680 is a red LED indication component manufactured by Broadcom Limited, featuring a 642nm dominant wavelength and 1.8V forward voltage in a 2-SMD, No Lead surface mount right-angle package. This part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production and maintenance applications. Substitute parts must maintain compatibility across electrical characteristics, mechanical dimensions, and mounting configuration to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HSMH-C680 are qualified based on the following critical parameters:

Electrical Compatibility: Forward voltage (Vf) within acceptable operating range, test current at 20mA, red color spectrum (wavelength 619nm–657nm dominant range)

Mechanical Compatibility: 2-SMD, No Lead package configuration, surface mount right-angle mounting type, lens dimensions 2.00mm x 1.00mm, overall height not exceeding 1.20mm

Regulatory Compliance: ROHS3 compliance and EAR99 ECCN classification maintained across all substitutes

The identified substitute parts—12-21SRC/TR8 (Everlight Electronics), APA3010EC (Kingbright), and APECVA3010EC (Kingbright)—meet these criteria with minor variations in forward voltage (1.7V–2.0V), millicandela rating (15–24.5mcd), and wavelength peak values within acceptable tolerance for red LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

12-21SRC/TR8 (Everlight Electronics): Active product status with ROHS3 compliance path. Forward voltage of 1.7V represents the closest electrical match to the HSMH-C680 at 1.8V. Millicandela rating of 24.5mcd provides 80% of original brightness. Width dimension increases to 2.00mm; height remains within specification at 1.20mm maximum. Tape & Reel packaging supports high-volume production environments.

APA3010EC (Kingbright): Active product with confirmed ROHS3 compliance and 3-level moisture sensitivity rating. Forward voltage of 2V requires circuit evaluation for voltage-sensitive applications. Millicandela rating of 15mcd represents 49% of original brightness; suitable for applications where reduced luminous intensity is acceptable. Maintains 1.00mm maximum height. Tape & Reel packaging available.

APECVA3010EC (Kingbright): Functionally identical to APA3010EC with ROHS3 compliance. Packaging specification not provided in source data. Identical electrical and optical characteristics to APA3010EC. Moisture sensitivity level 3 (168 Hours) noted.

All three substitutes maintain ECCN EAR99 classification and 2-SMD, No Lead package configuration. Selection should prioritize application requirements for forward voltage tolerance, brightness level, and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can the 12-21SRC/TR8 be used as a direct replacement for HSMH-C680?

A: The 12-21SRC/TR8 provides functional equivalence with compatible mounting type, package configuration, and lens dimensions. Forward voltage differs by 0.1V (1.7V vs. 1.8V), and brightness is reduced to 24.5mcd from 30.7mcd. Circuit design must accommodate these electrical and optical variations.

Q: What is the primary difference between APA3010EC and APECVA3010EC?

A: Both parts share identical electrical specifications, optical characteristics, and compliance ratings. The primary distinction is packaging format; APA3010EC specifies Tape & Reel (TR) packaging, while APECVA3010EC packaging is not specified in available data.

Q: Are there dimensional compatibility concerns with substitute parts?

A: The 12-21SRC/TR8 increases width to 2.00mm (from 1.00mm) and height to 1.20mm (from 1.00mm). APA3010EC and APECVA3010EC increase width to 2.00mm but maintain 1.00mm height. PCB layout and mechanical clearance must be evaluated for each substitute.

Q: How does forward voltage variation affect circuit design?

A: The HSMH-C680 operates at 1.8V typical. Substitutes range from 1.7V (12-21SRC/TR8) to 2.0V (APA3010EC, APECVA3010EC). Current-limiting resistor values may require adjustment to maintain consistent LED brightness and circuit performance across the forward voltage range.

Q: What is the brightness difference between the main part and substitutes?

A: HSMH-C680 provides 30.7mcd. The 12-21SRC/TR8 delivers 24.5mcd (80% brightness). APA3010EC and APECVA3010EC deliver 15mcd (49% brightness). Application requirements for visual indication intensity must determine acceptable substitution.

Q: Are all substitutes ROHS3 compliant?

A: HSMH-C680, APA3010EC, and APECVA3010EC are confirmed ROHS3 compliant. The 12-21SRC/TR8 does not specify RoHS status in available data; compliance verification with the supplier is recommended.

Q: What packaging formats are available for production?

A: HSMH-C680 is supplied in Cut Tape (CT). The 12-21SRC/TR8 is supplied in Tape & Reel (TR). APA3010EC is supplied in Tape & Reel (TR). APECVA3010EC packaging format is not specified. Production volume and handling requirements should guide packaging selection.
