Substitute Part Grouping Explanation

The HSMC-C170 qualifies as a direct substitute for the HSMC-S670 based on the following critical parameters:

• Package Compatibility: Both parts use 0805 (2012 Metric) surface mount package with identical physical dimensions (2.00mm L x 1.25mm W, 0.80mm max height)
• Electrical Compatibility: Both maintain 1.9V forward voltage and 20mA test current specifications
• Optical Characteristics: Both emit red light at 626nm dominant wavelength with diffused lens transparency
• Mounting Type: Both are surface mount components with identical mounting requirements
• Compliance: Both share identical REACH, ECCN, and HTSUS classifications

The HSMC-C170 is an active product with higher brightness (90mcd vs. 50mcd) and improved viewing angle (170° vs. 165°), making it a direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

The HSMC-C170 is the recommended substitute for the obsolete HSMC-S670. Both components share identical electrical and mechanical specifications, ensuring direct PCB compatibility without design modifications. The HSMC-C170 is an active product with full manufacturing support and improved brightness and viewing angle characteristics. Both parts maintain identical compliance certifications (REACH Unaffected, EAR99, HTSUS 8541.41.0000) and moisture sensitivity levels (MSL 2A).

Frequently Asked Questions (FAQ)

Q: Can the HSMC-C170 be used as a direct replacement for the HSMC-S670 on existing PCBs?

A: Yes. Both parts use identical 0805 (2012 Metric) surface mount packages with matching physical dimensions (2.00mm L x 1.25mm W, 0.80mm height) and identical electrical specifications (1.9V forward voltage, 20mA test current). No PCB modifications are required.

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

A: The HSMC-C170 offers higher brightness (90mcd vs. 50mcd) and a wider viewing angle (170° vs. 165°). The peak wavelength differs slightly (637nm vs. 630nm), though the dominant wavelength remains 626nm for both. The HSMC-C170 is an active product, while the HSMC-S670 is obsolete.

Q: Are there any compliance or certification differences?

A: No. Both parts share identical REACH, ECCN, and HTSUS classifications. Both maintain MSL 2A (4 Weeks) moisture sensitivity levels.

Q: What packaging options are available for the HSMC-C170?

A: The HSMC-C170 is available in Cut Tape (CT) and Digi-Reel® packaging formats.

Q: Is the HSMC-C170 suitable for applications requiring the exact 50mcd brightness of the HSMC-S670?

A: The HSMC-C170 provides 90mcd brightness. Applications with specific brightness requirements below 90mcd should evaluate whether the higher output is acceptable for the intended application.
