Engineering Selection Recommendations

Primary Recommendation: 57102-F08-02-01RLF

The 57102-F08-02-01RLF is the direct successor to the obsolete 57102-F08-02-01R within the Amphenol ICC Minitek® 2.00mm series. This part maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. The thermoplastic insulation material and copper alloy contacts match the original design. This substitute is the preferred choice for applications requiring minimal design changes and maximum compatibility with existing PCB layouts and mating connectors.

Secondary Recommendation: Samtec MTMM Series (MTMM-102-04-G-D-157, MTMM-102-04-S-D-157, MTMM-102-04-SM-D-150, MTMM-102-04-T-D-157)

The Samtec MTMM-102 series provides cross-manufacturer alternatives with identical pitch, position count, and row configuration. These parts feature enhanced current rating (3A versus 2A) and extended operating temperature ranges (-55°C to 105°C or -55°C to 125°C). The cuttable header design offers additional flexibility for custom configurations. All variants are ROHS3 compliant and actively produced. Selection among MTMM variants depends on specific contact finish requirements and post length specifications for your application.

Not Recommended: 57102-G08-03LF

The 57102-G08-03LF is a 6-position variant and does not meet the 4-position requirement of the original part. This part is listed in the substitute database but is mechanically incompatible with existing mating connectors designed for 4-position headers.

Frequently Asked Questions (FAQ)

Q: Can I use the 57102-F08-02-01RLF as a direct replacement for the 57102-F08-02-01R?

A: Yes. The 57102-F08-02-01RLF maintains identical electrical and mechanical specifications including pitch, position count, row spacing, current rating, voltage rating, and contact configuration. The primary differences are active product status and RoHS compliance. Existing PCB layouts and mating connectors require no modification.

Q: What is the difference between the Amphenol ICC and Samtec substitute options?

A: Both manufacturers provide 4-position, 2-row, 2.00mm pitch headers compatible with the original part. Amphenol ICC (57102-F08-02-01RLF) maintains the thermoplastic insulation and copper alloy contacts of the original design. Samtec MTMM series use liquid crystal polymer insulation and phosphor bronze contacts, offering higher current rating (3A) and extended temperature ranges. The choice depends on whether your application requires exact material matching or can benefit from enhanced electrical performance.

Q: Are the Samtec MTMM-102 variants interchangeable with each other?

A: The MTMM-102 variants share identical pitch, position count, and row configuration but differ in contact finish, contact length, and post length. MTMM-102-04-G-D-157 features gold plating on both mating and post contacts. MTMM-102-04-S-D-157 uses gold mating finish with tin post finish. MTMM-102-04-SM-D-150 and MTMM-102-04-T-D-157 use tin mating finish. Selection must account for your specific contact length and post length requirements to ensure proper mating depth and solder joint formation.

Q: Why do some substitute parts show no voltage rating?

A: The Samtec MTMM series datasheets provided do not specify voltage rating values. However, all parts maintain UL94 V-0 flammability rating and are suitable for standard low-voltage applications. Verify voltage requirements against your specific application before selection.

Q: Can I use a substitute part with higher current rating (3A) in place of the original 2A part?

A: Yes. The Samtec MTMM series with 3A current rating exceeds the original 2A specification and are suitable for applications requiring the original 2A rating. Higher current rating provides additional design margin and does not create compatibility issues with existing circuitry designed for 2A operation.

Q: What is the significance of the "cuttable" feature in Samtec MTMM headers?

A: The cuttable design allows the header to be cut to custom lengths, providing flexibility for applications requiring fewer than 4 positions or custom row spacing. For standard 4-position, 2-row applications, this feature does not affect compatibility or performance.
