• 2-row layout with 0.079" (2.00mm) row spacing
• Surface mount solder termination
• Push-pull fastening mechanism
• Gold-plated mating contacts
• Operating temperature range of -55°C to 125°C
• 2A minimum current rating
• 200V minimum voltage rating
• UL94 V-0 flammability rating

Acceptable Variations:

• Contact finish thickness on mating surface (8.00µin to 30.0µin)
• Insulation material composition (Plastic or Liquid Crystal Polymer)
• Insulation height tolerance (0.165" to 0.177")
• Connector style (Board to Board or Board to Board/Cable)
• Additional features (Board Guide, Pick and Place)
• Packaging format (Tube or Tape & Reel)
• RoHS and REACH compliance status

Substitutes must maintain electrical compatibility and mechanical interchangeability with the original 55510-312LF footprint and mating interface.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - Amphenol ICC 55510-112LF

The 55510-112LF is the direct Amphenol ICC equivalent with active product status. It maintains identical electrical and mechanical specifications to the 55510-312LF, including 2A current rating, 200V voltage rating, and -55°C to 125°C operating temperature range. The primary difference is increased contact finish thickness (30.0µin versus 15.0µin), which enhances durability. This part is RoHS Compliant and available in Tube packaging with 1220 units in stock.

Secondary Substitutes - Hirose Electric A3 Series

The A3-12DA-2SV(71) and A3A-12DA-2SV(71) are Hirose Electric alternatives with ROHS3 Compliant status and active product status. Both maintain the 12-position, 2.00mm pitch configuration and push-pull fastening. Key differences include reduced operating temperature range (-55°C to 85°C), lower current rating (1A), and alternative insulation material (Polyphenylene Sulfide). The A3A-12DA-2SV(71) includes a Board Guide feature. These parts are suitable for applications within the reduced temperature specification.

Tertiary Substitutes - Samtec TLE Series

The TLE-106-01-G-DV-A-P-TR, TLE-106-01-G-DV-A-TR, and TLE-106-01-G-DV-K-TR are Samtec pass-through receptacles with ROHS3 Compliant status and active product status. These connectors maintain the 12-position, 2.00mm pitch interface and full -55°C to 125°C operating temperature range. Current rating is 3.2A per contact, exceeding the original specification. Pass-through design enables stacking capability. Available in Tape & Reel packaging.

Alternative - Samtec MMS-106-02-S-DV-P-TR

The MMS-106-02-S-DV-P-TR is a Samtec standard receptacle with 3.9A per contact current rating and active product status. It maintains the 12-position, 2.00mm pitch configuration and full operating temperature range. Insulation material is Liquid Crystal Polymer. Available in Tape & Reel packaging with 767 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the 55510-112LF directly replace the obsolete 55510-312LF?

A: Yes. The 55510-112LF is the direct Amphenol ICC equivalent with identical electrical and mechanical specifications. The only difference is increased gold plating thickness on mating contacts (30.0µin versus 15.0µin), which improves contact durability. Both parts share the same 12-position, 2.00mm pitch, 2A current rating, and 200V voltage rating.

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

A: The Hirose A3 series (A3-12DA-2SV(71) and A3A-12DA-2SV(71)) have a reduced operating temperature range (-55°C to 85°C versus -55°C to 125°C) and lower current rating (1A versus 2A). They use Polyphenylene Sulfide insulation instead of plastic. These parts are suitable only for applications within the reduced temperature specification. The A3A variant includes a Board Guide feature.

Q: Why do Samtec TLE connectors have higher current ratings?

A: The Samtec TLE series are pass-through receptacles with 3.2A per contact rating, compared to the original 2A specification. This higher rating reflects the connector design and contact geometry. These parts maintain full -55°C to 125°C operating temperature compatibility and are suitable for higher-current applications.

Q: Are all substitute parts RoHS compliant?

A: The 55510-112LF is RoHS Compliant. The Hirose A3 series parts are ROHS3 Compliant. The Samtec TLE series are ROHS3 Compliant. The Samtec MMS-106-02-S-DV-P-TR does not specify RoHS status. Verify compliance requirements for your specific application.

Q: What packaging options are available?

A: The Amphenol ICC 55510-112LF is available in Tube packaging. Hirose A3 series parts are available in Tube packaging. Samtec parts (TLE and MMS series) are available in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Can I use a pass-through connector (TLE series) in place of a standard receptacle?

A: Yes, mechanically and electrically. The Samtec TLE pass-through receptacles maintain the same 12-position, 2.00mm pitch interface and mating compatibility. The pass-through design allows signal routing through the connector, enabling stacking configurations. Verify your PCB layout accommodates the pass-through termination style.

Q: What is the difference between TLE-106-01-G-DV-A-TR and TLE-106-01-G-DV-K-TR?

A: Both are Samtec TLE series pass-through receptacles with identical electrical specifications. The primary difference is the feature set: TLE-106-01-G-DV-A-TR includes Board Guide, while TLE-106-01-G-DV-K-TR includes Pick and Place feature. Both maintain 3.2A per contact rating and full operating temperature range.

Q: Are insulation material differences significant for my application?

A: Insulation material affects thermal and chemical resistance. The original 55510-312LF uses plastic insulation. Hirose A3 series use Polyphenylene Sulfide (PPS), offering higher temperature capability. Samtec TLE and MMS series use Liquid Crystal Polymer (LCP), providing superior dimensional stability and chemical resistance. Select based on your application environment and thermal requirements.
