Pitch and row spacing: 0.079" (2.00mm) mating pitch with 2-row configuration
Mounting: Surface mount with solder termination
Fastening: Push-pull mechanism
Mating contact finish: Gold plating
Operating temperature range: Minimum -55°C to 125°C capability
Current and voltage ratings: Minimum 2A at 200V

Substitute parts are grouped into two categories:

Direct Amphenol ICC Successor: 55510-032LF maintains identical electrical and mechanical specifications with updated RoHS compliance and active product status.

Cross-Manufacturer Equivalents: Hirose Electric A3-32DA-2SV(71) and A3A-32DA-2SV(71), and Samtec MMS-116 series variants meet the core substitution criteria of 32-position, 2.00mm pitch, surface mount receptacle configuration with push-pull fastening and gold mating contacts.

Engineering Selection Recommendations

Primary Recommendation: 55510-032LF

The 55510-032LF is the direct successor to the 55510-032, manufactured by Amphenol ICC. It maintains identical electrical and mechanical specifications while achieving RoHS compliance and active product status. This part is the preferred choice for designs requiring minimal qualification effort and maximum compatibility with existing tooling and assembly processes.

Secondary Recommendation: Hirose Electric A3-32DA-2SV(71) or A3A-32DA-2SV(71)

These Hirose connectors provide cross-manufacturer equivalence with identical 32-position, 2.00mm pitch, surface mount configuration. Both parts are ROHS3 compliant and active. The A3A-32DA-2SV(71) variant includes a board guide feature. Note that these parts operate at a reduced temperature maximum of -55°C to 85°C and carry a 1A current rating per contact, which may require design review for applications demanding the full 2A rating of the original part.

Tertiary Recommendation: Samtec MMS-116 Series

The Samtec MMS-116-02-F-DV and MMS-116-02-L-DV variants (10, 11, 12, 14, 15, 16) meet the core substitution criteria with 32-position, 2.00mm pitch, surface mount receptacle configuration. These parts maintain the full -55°C to 125°C operating range and offer 3.9A per contact current capacity. The MMS-116-02-L-DV variants are loaded with 31 of 32 positions. All Samtec options are ROHS3 compliant and active.

Frequently Asked Questions (FAQ)

Q: Can the 55510-032 be directly replaced with the 55510-032LF?

A: Yes. The 55510-032LF is the direct Amphenol ICC successor with identical electrical and mechanical specifications. The primary difference is RoHS compliance status and active product availability. No design changes are required.

Q: What are the key differences between Amphenol ICC and Hirose Electric substitutes?

A: The Hirose A3 series maintains the 32-position, 2.00mm pitch, surface mount, push-pull configuration. However, the operating temperature range is limited to -55°C to 85°C (versus -55°C to 125°C for the original), and the current rating is 1A per contact (versus 2A for the original). Applications operating above 85°C or requiring 2A per contact must use Amphenol ICC or Samtec alternatives.

Q: What distinguishes the Samtec MMS-116-02-F-DV from the MMS-116-02-L-DV variants?

A: The MMS-116-02-F-DV is fully loaded with all 32 positions. The MMS-116-02-L-DV variants (10, 11, 12, 14, 15, 16) are loaded with 31 of 32 positions. Selection depends on application requirements for position count and specific contact loading configuration.

Q: Are there mechanical compatibility concerns when substituting cross-manufacturer parts?

A: All listed substitutes share identical 2.00mm pitch, 2-row configuration, and surface mount termination. However, insulation height and contact geometry may vary slightly between manufacturers. Physical fit verification on the mating connector is recommended before production implementation.

Q: Which substitute offers the best current capacity?

A: The Samtec MMS-116 series provides 3.9A per contact, exceeding the original 2A specification. This offers design margin for applications with current growth potential.

Q: Are all substitutes RoHS compliant?

A: The original 55510-032 is RoHS non-compliant. All listed substitutes (55510-032LF, Hirose A3 series, and Samtec MMS-116 series) are RoHS3 compliant, meeting current regulatory requirements.
