Amphenol ICC 57102-G08-24 Rectangular Connector Header — Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 57102-G08-24 is a through-hole rectangular connector header in the Minitek® 2.00mm series, configured for 48 positions across 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 continuity. The connector features male pins with gold-plated mating contacts, tin-plated posts, and solder termination suitable for board-to-board applications. Substitution is necessary to ensure access to components with active product status and current manufacturing support.

Substitute Part Grouping Explanation

Substitution for the 57102-G08-24 is organized into two categories based on electrical and mechanical compatibility:

Category 1: Direct Amphenol ICC Equivalents These parts maintain identical pitch (0.079" / 2.00mm), position count (48), row configuration (2), and board-to-board mounting style. Substitutes in this category differ primarily in product status (active vs. obsolete) and RoHS compliance. The 57102-G08-24LF is the direct active equivalent with identical electrical and mechanical specifications.

Category 2: Cross-Manufacturer Alternatives These parts share the core mating pitch (0.079" / 2.00mm), position count (48), row configuration (2), and through-hole mounting, but originate from different manufacturers (3M, Samtec) and may exhibit variations in contact length, material composition, or contact finish specifications. These alternatives are suitable when manufacturer flexibility is acceptable and mechanical envelope constraints permit minor dimensional variations.

Key Parameters Determining Substitution:

Pitch - Mating: 0.079" (2.00mm)
Number of Positions: 48
Number of Rows: 2
Mounting Type: Through Hole
Connector Type: Header
Contact Type: Male Pin
Termination: Solder

Engineering Selection Recommendations

Primary Recommendation: 57102-G08-24LF The 57102-G08-24LF is the direct equivalent from Amphenol ICC with active product status and RoHS compliance. This part maintains identical electrical specifications (2A current rating, 200V voltage rating) and mechanical configuration (48 positions, 2 rows, 0.079" pitch, through-hole mounting). Selection of this part eliminates design re-qualification and ensures compatibility with existing PCB layouts and mating connectors.

Secondary Recommendation: Samtec MTMM-124 Series The Samtec MTMM-124 series (variants 02-G-D-155, 04-F-D-154, 04-G-D-157, 04-L-D-154, 04-L-D-157, 05-L-D-157, 05-T-D-150) provides active alternatives with enhanced current rating (3A) and ROHS3 compliance. These parts maintain the 0.079" (2.00mm) pitch and 48-position, 2-row configuration. Mating contact length varies between 0.150" and 0.157", and post length varies between 0.041" and 0.168". Selection requires verification that mechanical envelope constraints accommodate these dimensional variations and that the cuttable header feature aligns with application requirements.

Alternative Recommendation: 3M 951248-8622-AR The 3M 951248-8622-AR maintains the 0.079" (2.00mm) pitch and 48-position configuration with active product status and RoHS compliance. This part exhibits a reduced current rating (1A) and mating contact length of 0.173" (4.40mm). Selection is appropriate only when current requirements do not exceed 1A and mechanical envelope permits the increased contact length.

Frequently Asked Questions (FAQ)

Q: Can the 57102-G08-24LF be used as a direct replacement for the 57102-G08-24? A: Yes. The 57102-G08-24LF is the direct active equivalent with identical electrical and mechanical specifications. The primary difference is product status (active vs. 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-G08-24LF maintains the original 2A current rating and 200V voltage rating. Samtec MTMM-124 series parts provide higher current rating (3A) but do not specify voltage rating. Samtec parts feature cuttable header design and phosphor bronze contact material versus copper alloy in the Amphenol part. Mating contact length varies across Samtec variants (0.150" to 0.157") compared to the fixed 0.157" in the original part.

Q: Are there mounting compatibility concerns when switching between manufacturers? A: All substitute parts maintain 0.079" (2.00mm) pitch and through-hole mounting, ensuring PCB footprint compatibility. However, variations in overall contact length (ranging from 0.255" to 0.377" across alternatives) may affect mating connector engagement depth. Mechanical envelope verification is required before final selection.

Q: Which substitute part offers the best compliance profile? A: The 57102-G08-24LF provides RoHS compliance. Samtec MTMM-124 series parts provide ROHS3 compliance. The 3M 951248-8622-AR provides RoHS compliance. Selection depends on specific regulatory requirements for the application.

Q: Can Samtec MTMM-124 parts be used in applications requiring 2A current? A: Samtec MTMM-124 parts are rated for 3A current, which exceeds the 2A requirement of the original part. These parts are suitable for applications requiring up to 3A. However, voltage rating is not specified for Samtec parts, requiring verification against application voltage requirements.

Q: What is the significance of the cuttable header feature in Samtec parts? A: Samtec MTMM-124 series parts feature cuttable header design, allowing field customization of position count. This feature is not present in the Amphenol ICC or 3M alternatives. Selection of Samtec parts is appropriate only when this feature provides design advantage or when position count flexibility is required.
