Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing support, eliminating obsolescence risk associated with the 3M 953216-2000-AR-TP. Selection should prioritize parts with RoHS3 compliance and REACH unaffected status for regulatory alignment in new designs.

Molex Milli-Grid Series (0872631603, 0872631693): Active status with board guide and pick-and-place features. Voltage rating of 125VAC is lower than the original specification; applications requiring 1000VDC operation require evaluation against actual circuit requirements.

Hirose A3 Series (A3-16DA-2SV(71), A3A-16DA-2SV(71)): Active status with RoHS3 compliance and REACH unaffected designation. Operating temperature maximum of 85°C is lower than the original -40°C to 105°C range. The A3A variant includes board guide feature. Voltage rating of 200VAC is lower than original specification.

Samtec Tiger Eye SMM Series (SMM-108-02-F-D variants): All variants are active with RoHS3 compliance. Current rating of 3.2A per contact exceeds original 1A specification. Operating temperature range of -55°C to 125°C exceeds original specification. Voltage rating of 350VAC is lower than original 1000VDC specification. Variants with "-LC" designation include board lock feature; "-K" variants include pick-and-place capability. SMM-108-02-F-D-08-K-TR has 15 positions loaded versus 16 positions in the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a lower voltage rating than the original 1000VDC specification?

A: Voltage rating substitution depends on your circuit requirements. If your application operates at or below the substitute part's voltage rating, the part is suitable. If your circuit requires 1000VDC operation, only substitute parts meeting or exceeding this specification are appropriate. Samtec SMM-108 series parts are rated for 350VAC maximum.

Q: What is the difference between the Samtec SMM-108-02-F-D variants?

A: All SMM-108-02-F-D variants share the same core electrical and mechanical specifications. Differences are in optional features: "-LC" adds board lock functionality, "-K" adds pick-and-place capability, "-08-K-TR" has 15 positions loaded with pick-and-place and tape-and-reel packaging, and "-14" has 15 positions loaded in tube packaging.

Q: Are the Hirose A3 series parts suitable for applications requiring the full -40°C to 105°C temperature range?

A: Hirose A3 series parts operate from -55°C to 85°C. If your application requires operation above 85°C, these parts are not suitable. Samtec SMM-108 series parts operate to 125°C and accommodate higher temperature requirements.

Q: What packaging options are available for these substitute parts?

A: Molex 0872631693 is supplied in tape and reel packaging. Hirose A3 series parts are supplied in tube packaging. Samtec SMM-108-02-F-D-08-K-TR is supplied in tape and reel; other Samtec variants are supplied in tube packaging. Molex 0872631603 packaging is not specified in the provided data.

Q: Do all substitute parts have the same insulation height as the original 3M connector?

A: No. The original 3M part has insulation height of 0.169" (4.30mm). Molex parts are 0.110" (2.79mm), Hirose parts are 0.165" (4.20mm), and Samtec parts are 0.140" (4.66mm). Verify PCB layout compatibility with the specific substitute part's dimensions.

Q: Which substitute parts have board guide features?

A: Molex 0872631603 and 0872631693 include board guide features. Hirose A3A-16DA-2SV(71) includes board guide. Samtec SMM-108-02-F-D-LC and SMM-108-02-F-D-LC-K include board lock features, which provide similar mechanical alignment benefits.
