HSMA-S690 Equivalent & Substitute Parts

Part Overview

The HSMA-S690 is an amber LED indicator component manufactured by Broadcom Limited, designed for discrete indication applications in 0603 (1608 Metric) surface mount packages. This part operates at 1.9V forward voltage with a 590nm dominant wavelength and delivers 65mcd brightness at 20mA test current. The HSMA-S690 is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSMA-S690 is based on the following critical parameters that must remain consistent:

• Package / Case: 0603 (1608 Metric) surface mount form factor
• Voltage - Forward (Vf) (Typ): 1.9V nominal operating voltage
• Current - Test: 20mA test current specification
• Color: Amber indication
• Lens Transparency: Diffused optical characteristic
• Mounting Type: Surface mount compatibility

The HSMA-C191 qualifies as a direct substitute based on matching all mandatory electrical and mechanical parameters. Variations in millicandela rating (65mcd to 90mcd), viewing angle (165° to 170°), and wavelength peak values (592nm to 595nm) remain within acceptable tolerance ranges for amber LED indication applications and do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

The HSMA-C191 is the qualified substitute for the obsolete HSMA-S690. Both components are manufactured by Broadcom Limited and share identical electrical specifications (1.9V forward voltage, 20mA test current) and mechanical compatibility (0603 package, surface mount). The HSMA-C191 maintains active product status, ensuring ongoing availability and supply chain continuity.

The HSMA-C191 exhibits improved performance characteristics: increased brightness (90mcd versus 65mcd), wider viewing angle (170° versus 165°), and reduced maximum height (0.60mm versus 0.80mm). These enhancements do not introduce incompatibility with existing circuit designs. Both components comply with identical moisture sensitivity levels (2A, 4 Weeks) and share REACH unaffected status.

Selection of the HSMA-C191 is supported by equivalent RoHS3 compliance and identical ECCN/HTSUS classifications, confirming regulatory and trade alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can the HSMA-C191 be used as a direct replacement for the HSMA-S690 in existing PCB designs?

A: Yes. Both components share identical package dimensions (0603 / 1608 Metric), forward voltage (1.9V), test current (20mA), and mounting type (surface mount). PCB footprints and circuit designs require no modification.

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

A: The HSMA-C191 provides higher brightness (90mcd versus 65mcd), a wider viewing angle (170° versus 165°), and a lower profile (0.60mm maximum height versus 0.80mm). Wavelength specifications differ slightly (dominant 592nm versus 590nm), remaining within amber LED specification ranges. The HSMA-C191 is active product status, while the HSMA-S690 is obsolete.

Q: Are there any compliance or regulatory differences?

A: No. Both components share identical moisture sensitivity levels (2A, 4 Weeks), REACH unaffected status, and ECCN/HTSUS classifications. The HSMA-C191 carries RoHS3 compliance certification.

Q: Does the increased brightness of the HSMA-C191 affect circuit compatibility?

A: No. Both parts operate at identical forward voltage and test current specifications. The increased millicandela rating does not alter electrical behavior or require circuit redesign.

Q: What is the inventory status of these parts?

A: The HSMA-S690 is obsolete with 41,300 pieces in stock. The HSMA-C191 is active product with 161,100 pieces available, ensuring reliable supply for new designs and production continuity.
