Amphenol ICC 57102-S08-04 Rectangular Connector Header — Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 57102-S08-04 is a through-hole rectangular connector header in the Minitek® 2.00mm series, featuring 8 positions arranged in 2 rows with 0.079" (2.00mm) pitch. This part is classified as obsolete, making identification of active equivalent and substitute components essential for ongoing design support and procurement.

The connector is designed for board-to-board applications with solder termination and push-pull fastening. Its unshrouded design and square male pin contacts with gold-plated mating surfaces support applications requiring 2A current at 200V (AC/DC). The obsolete status necessitates evaluation of direct equivalents and alternative manufacturers offering compatible solutions.

Substitute Categories:

Category 1: Direct Amphenol ICC Equivalent The part 57102-S08-04LF is the active production equivalent from the same manufacturer and series. It maintains identical electrical and mechanical specifications while offering RoHS compliance and active product status.

Category 2: Amphenol ICC Alternative (Different Mounting) The part 57202-S51-25LF is a surface-mount variant within the same Minitek® 2.00mm series. While it shares pitch, row spacing, and core electrical characteristics, its 50-position configuration and surface-mount termination make it suitable only for applications where position count and mounting method can be adapted.

Category 3: Samtec Inc. Cross-Manufacturer Alternatives Multiple Samtec MTMM series headers provide functional equivalence with variations in contact length, material composition, and operating temperature ranges. These parts maintain the critical 0.079" (2.00mm) pitch, 8-position, 2-row configuration, and through-hole solder termination. Samtec variants offer higher current ratings (3A) and extended operating temperature ranges (-55°C to 125°C or -55°C to 105°C depending on finish), with contact material upgraded to phosphor bronze and insulation material to liquid crystal polymer (LCP).

Engineering Selection Recommendations

Primary Recommendation: 57102-S08-04LF

The Amphenol ICC 57102-S08-04LF is the direct active equivalent of the obsolete 57102-S08-04. This part maintains identical electrical and mechanical specifications while offering RoHS compliance and active product status. Selection of this part eliminates design modification requirements and ensures compatibility with existing mating connectors and PCB layouts. Current inventory of 671 units supports immediate procurement.

Secondary Recommendation: Samtec MTMM Series (MTMM-104-02-G-D-150, MTMM-104-02-G-D-155, MTMM-104-02-S-D-155, MTMM-104-02-T-D-150, MTMM-104-03-G-D-157, MTMM-104-03-T-D-155, MTMM-104-04-F-D-157, MTMM-104-04-G-D-155-001)

Samtec MTMM series headers provide cross-manufacturer alternatives with enhanced electrical performance and compliance. These parts maintain the critical 0.079" (2.00mm) pitch, 8-position, 2-row configuration, and through-hole solder termination. Key advantages include higher current rating (3A versus 2A), extended operating temperature ranges, and ROHS3 compliance. Contact length variations accommodate different PCB stack-up requirements. Selection of Samtec alternatives requires verification of contact length compatibility with mating connector specifications and PCB design parameters.

Not Recommended for Direct Substitution: 57202-S51-25LF

The Amphenol ICC 57202-S51-25LF is a surface-mount variant with 50 positions. While it shares the Minitek® 2.00mm pitch and core electrical characteristics, its fundamentally different mounting method and position count make it unsuitable as a direct substitute without significant design modification.

Frequently Asked Questions (FAQ)

Q: Can I use 57102-S08-04LF as a direct replacement for 57102-S08-04?

A: Yes. The 57102-S08-04LF is the active production equivalent from Amphenol ICC. It maintains identical pitch (0.079" / 2.00mm), position count (8), row configuration (2 rows), contact type (male pin), mounting method (through-hole), and termination (solder). The primary difference is product status (active versus obsolete) and RoHS compliance. No design modification is required.

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

A: Amphenol ICC 57102-S08-04LF maintains exact electrical and mechanical specifications of the original part. Samtec MTMM series alternatives offer enhanced performance with higher current rating (3A versus 2A), extended operating temperature ranges (-55°C to 125°C or -55°C to 105°C), upgraded contact material (phosphor bronze versus copper alloy), and improved insulation material (liquid crystal polymer versus thermoplastic). Contact length varies across Samtec variants to accommodate different PCB stack-up configurations. All alternatives maintain the critical 0.079" (2.00mm) pitch and 8-position, 2-row configuration.

Q: Are there compatibility concerns when switching from Amphenol ICC to Samtec?

A: Compatibility depends on mating connector specifications and PCB design parameters. The 0.079" (2.00mm) pitch, 8-position, 2-row configuration, and push-pull fastening are consistent across all alternatives. Contact length variations in Samtec parts (ranging from 0.255" to 0.323" overall length) must be verified against mating connector depth and PCB stack-up requirements. Consult mating connector documentation to confirm contact length compatibility before design implementation.

Q: What is the significance of contact length variations in Samtec MTMM parts?

A: Contact length determines the depth of connector engagement and the amount of post extending through the PCB. Samtec MTMM variants offer multiple contact length options to accommodate different PCB thicknesses and mating connector specifications. The main part (57102-S08-04) has an overall contact length of 0.335" (8.51mm). Samtec alternatives range from 0.255" to 0.323". Selection must align with mating connector specifications and PCB design requirements.

Q: Why do some Samtec parts have tin finish while others have gold finish?

A: Contact finish selection affects corrosion resistance and mating durability. Gold-finished contacts (MTMM-104-02-G-D-150, MTMM-104-02-G-D-155, MTMM-104-03-G-D-157, MTMM-104-04-F-D-157, MTMM-104-04-G-D-155-001) provide superior corrosion resistance and are suitable for applications requiring extended shelf life or harsh environments. Tin-finished contacts (MTMM-104-02-T-D-150, MTMM-104-03-T-D-155) are cost-effective alternatives for standard applications. The main part uses gold finish (GXT™). Selection should align with application environment and reliability requirements.

Q: Is the 57202-S51-25LF a viable substitute?

A: No. The 57202-S51-25LF is a surface-mount connector with 50 positions, fundamentally different from the through-hole, 8-position main part. While it shares the Minitek® 2.00mm pitch and core electrical characteristics, substitution would require complete PCB redesign and mating connector replacement. This part is listed as a reference only and is not recommended for direct substitution.

Q: What compliance certifications should I verify before design implementation?

A: All active alternatives (57102-S08-04LF and Samtec MTMM series) are RoHS compliant. The original part (57102-S08-04) is RoHS non-compliant. All parts maintain UL94 V-0 material flammability rating. Verify that selected alternative meets your application's specific compliance requirements, including RoHS, REACH, and any industry-specific certifications.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels are: 57102-S08-04LF (671 units), MTMM-104-02-G-D-150 (1077 units), MTMM-104-02-G-D-155 (842 units), MTMM-104-02-S-D-155 (823 units), MTMM-104-02-T-D-150 (895 units), MTMM-104-03-G-D-157 (711 units), MTMM-104-03-T-D-155 (929 units), MTMM-104-04-F-D-157 (881 units), MTMM-104-04-G-D-155-001 (705 units). Samtec alternatives offer higher inventory availability. Procurement planning should account for lead times and volume requirements.
