Engineering Selection Recommendations

Primary Substitutes (Full 16-Position, All Positions Loaded):

Molex 0872631603 and 0872631693 are active production equivalents from a major connector manufacturer. Both maintain the 16-position, 2.00mm pitch configuration with identical contact loading. The Tape & Reel packaging option (0872631693) accommodates automated assembly workflows. These parts carry ROHS3 compliance and unlimited moisture sensitivity rating. Operating temperature range extends to -55°C, exceeding the original specification. Voltage rating of 125VAC is lower than the original 1000VDC specification; applications requiring higher voltage ratings should reference Samtec alternatives.

Hirose Electric A3-16DA-2SV(71) and A3A-16DA-2SV(71) provide active alternatives with ROHS3 compliance. The A3A variant includes board guide features. Both operate to -55°C and carry 200VAC voltage rating. Operating temperature upper limit of 85°C is lower than the original 105°C specification; thermal applications approaching 100°C should be evaluated against this constraint.

Enhanced Performance Substitutes (Samtec Tiger Eye™ SMM Series):

Samtec SMM-108-02-F-D, SMM-108-02-F-D-K, SMM-108-02-F-D-LC, and SMM-108-02-F-D-LC-K maintain full 16-position loading with enhanced electrical performance. Current rating of 3.2A per contact exceeds the original 1A specification. Voltage rating of 350VAC accommodates higher-voltage applications. Operating temperature range of -55°C to 125°C exceeds both upper and lower limits of the original part. All variants carry ROHS3 compliance. Feature variations include board lock (LC suffix) and pick-and-place optimization (K suffix). These parts are suitable for applications requiring higher current capacity or extended temperature operation.

Partial-Loading Variants (15-Position Loaded):

Samtec SMM-108-02-F-D-08-K-TR and SMM-108-02-F-D-14 are configured with 15 positions loaded. These variants are applicable only when circuit designs accommodate reduced position count. Both maintain the 2.00mm pitch and push-pull fastening. SMM-108-02-F-D-14 carries ROHS3 compliance; SMM-108-02-F-D-08-K-TR compliance status is not specified.

Frequently Asked Questions (FAQ)

Q: Can Molex 0872631603 directly replace the 3M 953216-2020-AR-PR in all applications?

A: Molex 0872631603 maintains mechanical and electrical interface compatibility at the 16-position, 2.00mm pitch level. However, the voltage rating of 125VAC is significantly lower than the original 1000VDC specification. Applications operating above 125VAC require evaluation against actual circuit voltage requirements. The extended operating temperature range (-55°C to 105°C) covers the original specification.

Q: What is the difference between Samtec SMM-108-02-F-D-LC and SMM-108-02-F-D-LC-K?

A: Both parts are identical in electrical and mechanical specifications. The -K suffix indicates pick-and-place optimization features for automated assembly. Selection depends on manufacturing process requirements. The board lock feature (LC suffix) is present in both variants.

Q: Are the Hirose A3-16DA-2SV(71) and A3A-16DA-2SV(71) interchangeable?

A: Both parts share identical electrical specifications and 16-position, 2.00mm pitch configuration. The A3A variant includes board guide features. Mechanical compatibility with existing mating connectors should be verified before substitution, as the board guide may affect insertion force or alignment requirements.

Q: Why do some Samtec parts show 15 positions loaded instead of 16?

A: SMM-108-02-F-D-08-K-TR and SMM-108-02-F-D-14 are manufactured with 15 active contact positions. These variants are applicable only when circuit designs accommodate reduced position count. Full 16-position loading is available in other SMM-108 variants listed.

Q: What packaging options are available for high-volume production?

A: Molex 0872631693 is supplied in Tape & Reel format, optimized for automated pick-and-place assembly. Samtec SMM-108 series variants are available in Tube packaging. Packaging selection should align with manufacturing equipment capabilities and volume requirements.

Q: Does the operating temperature range affect substitution decisions?

A: Yes. Hirose A3-16DA-2SV(71) and A3A-16DA-2SV(71) operate to 85°C maximum, which is 20°C below the original specification of 105°C. Applications with thermal profiles approaching or exceeding 85°C should use Samtec SMM-108 series (rated to 125°C) or Molex variants (rated to 105°C).

Q: Are all substitute parts RoHS3 compliant?

A: Molex 0872631603, 0872631693, Hirose A3-16DA-2SV(71), A3A-16DA-2SV(71), and all Samtec SMM-108 variants except SMM-108-02-F-D-08-K-TR carry explicit ROHS3 compliance certification. Compliance status for SMM-108-02-F-D-08-K-TR is not specified in available documentation.
