Amphenol ICC 57102-F08-03 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 57102-F08-03 is a vertical board-to-board rectangular connector header with 6 positions arranged in 2 rows at 2.00mm pitch. This through-hole solder-terminated component features male pins with gold-plated mating contacts and is designed for applications requiring reliable interconnection in compact form factors. The part is currently obsolete, making equivalent and substitute components necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility through matching pitch, position count, row configuration, and contact ratings while accommodating variations in contact length, finish specifications, and material composition.

Engineering Selection Recommendations

Primary Substitute: 57102-F08-03LF (Amphenol ICC)

The 57102-F08-03LF is the direct functional equivalent of the obsolete 57102-F08-03. This part maintains identical electrical and mechanical specifications including pitch, position count, row configuration, contact length, and current/voltage ratings. The primary distinction is product status: the 57102-F08-03LF is active and widely available with 2217 units in stock. Additionally, the 57102-F08-03LF achieves RoHS compliance, addressing regulatory requirements that the original part does not meet. For applications requiring minimal design modification and maximum compatibility, this part is the preferred choice.

Alternative Substitutes: Samtec MTMM Series

The Samtec MTMM-103 series provides manufacturer-recommended alternatives with enhanced specifications. All MTMM variants maintain the critical electrical and mechanical parameters: 2.00mm pitch, 6 positions in 2 rows, through-hole solder termination, and UL94 V-0 flammability rating. Key advantages include:

Current rating increased to 3A (versus 2A in original)
Operating temperature range specified as -55°C to 125°C
ROHS3 compliance across all variants
Phosphor Bronze contact material offering improved durability
Liquid Crystal Polymer (LCP) insulation providing enhanced thermal and chemical resistance
Cuttable header design enabling customization for specific position requirements

Selection among MTMM variants depends on contact length requirements and post-side finish specifications. Parts designated with "-03" or "-04" suffixes indicate different contact length configurations. Parts with "-G-D" designations feature gold post finishes, while "-L-D" and "-S-D" designations indicate tin post finishes. The "-05-G-D-150" variant provides extended post length (0.168") for applications requiring deeper PCB penetration.

Compliance Considerations

The original 57102-F08-03 is RoHS non-compliant. All substitute parts listed achieve either RoHS or ROHS3 compliance, making them suitable for applications subject to RoHS regulations. The 57102-G08-05LF, while listed in the original substitute documentation, is a 10-position variant and is not electrically equivalent for 6-position applications.

Frequently Asked Questions (FAQ)

Q: Can I use the 57102-F08-03LF as a direct replacement for the obsolete 57102-F08-03?

A: Yes. The 57102-F08-03LF is electrically and mechanically identical to the 57102-F08-03. Both parts feature 6 positions at 2.00mm pitch, identical contact lengths, and matching current/voltage ratings. The primary differences are product status (active versus obsolete) and RoHS compliance. No design modifications are required for substitution.

Q: What are the key differences between Amphenol ICC and Samtec alternatives?

A: Amphenol ICC 57102-F08-03LF maintains exact dimensional and electrical parity with the original part. Samtec MTMM-103 series variants offer enhanced specifications including higher current rating (3A versus 2A), specified operating temperature range (-55°C to 125°C), and improved insulation material (LCP versus thermoplastic). Contact material differs (Phosphor Bronze versus Copper Alloy), and post-side finishes vary by part number. All variants maintain the critical 2.00mm pitch and 6-position configuration.

Q: Do contact length variations affect PCB compatibility?

A: Contact length variations must be evaluated against specific PCB thickness and application requirements. The original 57102-F08-03 features 0.118" (3.00mm) post length. Samtec MTMM variants range from 0.090" to 0.168" post length. Shorter post lengths (0.090"-0.093") suit thin PCBs, while longer posts (0.168") accommodate thicker boards. Mating contact length variations (0.150"-0.157") are within acceptable tolerance for standard connector receptacles.

Q: Are all substitute parts RoHS compliant?

A: The original 57102-F08-03 is RoHS non-compliant. The 57102-F08-03LF achieves RoHS compliance. All Samtec MTMM-103 variants achieve ROHS3 compliance. For applications subject to RoHS regulations, any of the listed substitutes are acceptable.

Q: What does "cuttable" mean in the Samtec MTMM series?

A: Cuttable headers allow customization of the final position count by cutting the header to the required length. The MTMM-103 series is manufactured as longer strips that can be cut to specific configurations. This feature does not affect electrical or mechanical compatibility for 6-position applications; the part functions identically to non-cuttable headers when used at full length.

Q: Can I mix contact finish specifications (gold versus tin post)?

A: Contact finish specifications are determined by soldering process requirements and environmental exposure. Gold post finishes (MTMM variants with "-G-D" designation) provide enhanced corrosion resistance. Tin post finishes (MTMM variants with "-L-D" and "-S-D" designations) are standard for wave soldering processes. Selection should align with manufacturing process and environmental requirements. Mixing different finishes within a single assembly is not recommended.

Q: What is the significance of the "-150", "-152", "-153", "-155", "-157" suffixes in Samtec part numbers?

A: These suffixes indicate specific contact length configurations. The numeric value represents the mating contact length in thousandths of an inch (0.150" = 150, 0.157" = 157, etc.). Selection depends on connector receptacle specifications and mating force requirements. All variants maintain electrical compatibility; selection is based on mechanical fit and application-specific contact engagement depth.

Q: Is the 57102-G08-05LF a suitable substitute?

A: No. The 57102-G08-05LF is a 10-position variant, not a 6-position part. While it shares the same 2.00mm pitch and manufacturer, it is not electrically equivalent for applications requiring 6-position connectivity. This part is listed in the original documentation as a cross-reference but does not serve as a functional substitute.
