Engineering Selection Recommendations

Both the 57102-F08-02-01RLF and MTMM-102-04-T-D-157 are active products with full RoHS compliance and MSL 1 ratings. The Samtec MTMM-102-04-T-D-157 offers a higher current rating (3A versus 2A) and specified operating temperature range (-55°C ~ 105°C), providing additional performance margin in thermally demanding applications. The cuttable header design of the Samtec part enables post-manufacturing customization of position count if required. Both connectors maintain identical mating geometry, pitch, and fastening characteristics, ensuring mechanical and electrical interchangeability within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can the MTMM-102-04-T-D-157 be used as a direct replacement for the 57102-F08-02-01RLF?

A: Yes. Both connectors share identical mating pitch (2.00mm), position count (4), row configuration (2 rows), contact length (4.00mm), and insulation height (1.50mm). The push-pull fastening mechanism and through-hole solder termination are identical. Mating compatibility is assured.

Q: What is the difference in contact post length between these two parts?

A: The 57102-F08-02-01RLF has a contact post length of 0.118" (3.00mm), while the MTMM-102-04-T-D-157 has 0.107" (2.71mm). This 0.011" (0.29mm) difference is within typical PCB tolerance ranges and does not affect electrical performance or mating reliability.

Q: Why does the Samtec part have a higher current rating?

A: The MTMM-102-04-T-D-157 is rated for 3A compared to the Amphenol ICC part's 2A rating. This reflects the contact material composition (Phosphor Bronze versus Copper Alloy) and insulation material properties (LCP versus Thermoplastic). The higher rating provides additional design margin for applications approaching the 2A limit.

Q: Are there packaging differences between these connectors?

A: The 57102-F08-02-01RLF is supplied in Box packaging, while the MTMM-102-04-T-D-157 is supplied in Bulk packaging. This affects order quantities and handling but does not impact component performance or compatibility.

Q: What does "cuttable" mean for the Samtec connector?

A: The MTMM-102-04-T-D-157 is designed to allow post-manufacturing separation of individual positions if required. The 57102-F08-02-01RLF is a fixed 4-position header. For applications requiring exactly 4 positions, this distinction is not relevant.

Q: Are both parts RoHS compliant?

A: Yes. The 57102-F08-02-01RLF is RoHS Compliant, and the MTMM-102-04-T-D-157 is ROHS3 Compliant. Both meet current RoHS requirements.
