Engineering Selection Recommendations

Direct Amphenol ICC Replacement:

The 57102-G08-03LF is the primary direct substitute for the obsolete 57102-G08-03. Both parts maintain identical electrical and mechanical specifications with 2.00mm pitch, 6 positions, 2-row configuration, and 2A/200V ratings. The LF variant achieves RoHS compliance and REACH affected status, addressing regulatory requirements for new designs. This part is recommended for applications requiring minimal design changes and direct form-factor compatibility.

Samtec MTMM Series Alternatives:

The Samtec MTMM-103 series provides manufacturer-recommended alternatives with enhanced electrical performance and extended operating temperature range (-55°C to 125°C). These parts feature phosphor bronze contacts with improved durability compared to copper alloy, and Liquid Crystal Polymer insulation offering superior thermal and chemical resistance. Current rating increases to 3A, providing additional design margin. The MTMM series includes cuttable header variants, enabling custom position configurations for specific applications.

Compliance Considerations:

All substitute parts maintain UL94 V-0 flammability compliance and MSL 1 rating. The Amphenol ICC 57102-G08-03LF achieves RoHS compliance, suitable for regulated markets. Samtec MTMM parts carry ROHS3 compliance, meeting current regulatory standards. Selection between direct Amphenol replacement and Samtec alternatives depends on design requirements for operating temperature range, current capacity, and regulatory compliance scope.

Frequently Asked Questions (FAQ)

Q: Can MTMM-103 series parts directly replace the 57102-G08-03 without PCB redesign?

A: MTMM-103 parts maintain identical pitch (2.00mm), position count (6), and row spacing (2.00mm), enabling direct PCB footprint compatibility. However, contact length variations and overall connector height differences may require mechanical clearance verification. The cuttable header design of MTMM parts provides additional flexibility for custom configurations.

Q: What is the primary difference between 57102-G08-03LF and MTMM-103-03-G-D-150?

A: The 57102-G08-03LF maintains Amphenol ICC design with copper alloy contacts and thermoplastic insulation, preserving the original connector architecture with RoHS compliance. The MTMM-103-03-G-D-150 uses phosphor bronze contacts with LCP insulation, offering enhanced durability and extended operating temperature (-55°C to 125°C). Current rating increases from 2A to 3A in the Samtec variant.

Q: Are there position-loaded variants available?

A: The MTMM-103-04-G-D-155-006 is configured with 5 positions loaded instead of all 6 positions. This variant accommodates applications requiring reduced position count while maintaining the same connector footprint and electrical characteristics.

Q: What contact length options are available in the MTMM-103 series?

A: Contact length variations range from 0.150" (3.81mm) in MTMM-103-03-G-D-150 to 0.180" (4.57mm) in MTMM-103-04-H-D-180. These variations affect overall connector height and mating depth. Selection depends on PCB thickness, component clearance, and mechanical assembly requirements.

Q: Do all substitute parts carry the same voltage rating as the original 57102-G08-03?

A: The Amphenol ICC 57102-G08-03LF maintains the 200V (AC/DC) rating. Samtec MTMM-103 series parts do not specify voltage rating in the provided data. Voltage capability should be confirmed with manufacturer documentation for applications exceeding 100V.

Q: What is the significance of the cuttable header design in MTMM parts?

A: Cuttable headers allow custom position configurations by separating individual or groups of positions from the main strip. This feature enables cost-effective customization for applications requiring non-standard position counts without requiring unique part numbers.

Q: Are there contact finish variations among the substitutes?

A: Yes. The 57102-G08-03 and 57102-G08-03LF use gold-plated mating contacts with tin-plated posts. MTMM-103 variants offer multiple finish combinations: gold mating with gold posts (MTMM-103-03-G-D-150, MTMM-103-04-G-D-155-006, MTMM-103-04-H-D-180), gold with tin posts (MTMM-103-04-F-D-165, MTMM-103-04-L-D-157, MTMM-103-04-S-D-152, MTMM-103-04-S-D-157). Contact finish selection affects corrosion resistance and mating force characteristics.
