Amphenol ICC 57102-G08-03LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 57102-G08-03LF is an active rectangular connector header designed for through-hole board-to-board applications. This Minitek® 2.00mm series connector features 6 positions arranged in 2 rows with 0.079" (2.00mm) pitch spacing. The part is manufactured with gold-plated mating contacts and tin-plated posts, supporting 2A current at 200V AC/DC. Substitute parts are necessary when addressing specific application requirements such as higher current ratings, extended operating temperature ranges, or alternative contact finish specifications while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 57102-G08-03LF is determined by the following critical parameters that must remain constant across all alternatives:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 6
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Shrouding: Unshrouded
• Style: Board to Board or Board to Board/Cable
• Insulation Height: 0.059" (1.50mm)
• Contact Shape: Square
• Insulation Color: Black

The substitute parts listed below maintain these core parameters while offering variations in contact material composition, contact finish specifications, current ratings, and operating temperature ranges. All substitutes are active products with RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with RoHS3 requirements, ensuring long-term availability and regulatory compliance. The Samtec TMM and MTMM series alternatives provide enhanced electrical performance through higher current ratings (3.0A to 3.2A per contact) compared to the original 2A specification. The MTMM-103-03-G-D-150 variant offers a cuttable connector option with extended operating temperature range (-55°C to 125°C), suitable for applications requiring modular configuration flexibility. The TMM-103-03-G-D and TMM-103-03-L-D variants maintain the same contact length specifications as the original part while offering gold-plated post finishes for enhanced corrosion resistance. The TMM-103-03-T-D and TMM-103-03-TM-D variants employ tin-plated finishes on both mating and post contacts, with operating temperature limited to -55°C to 105°C. Selection should be based on specific application requirements for current capacity, temperature range, and contact finish durability.

Frequently Asked Questions (FAQ)

Q: Can the Samtec TMM series connectors directly replace the Amphenol ICC 57102-G08-03LF in existing PCB designs?

A: Yes, all listed Samtec substitutes maintain identical pitch (0.079" / 2.00mm), position count (6), row configuration (2 rows), and through-hole mounting specifications. PCB footprints are mechanically compatible. Electrical performance is enhanced with higher current ratings (3.0A to 3.2A per contact versus 2A original).

Q: What is the difference between the TMM-103-03-G-D and TMM-103-03-L-D variants?

A: Both variants share identical mechanical dimensions and current ratings (3.2A per contact). The primary difference is contact finish thickness on the mating surface: TMM-103-03-G-D provides 20.0µin (0.51µm) gold plating, while TMM-103-03-L-D provides 10.0µin (0.25µm) gold plating. The TMM-103-03-L-D uses tin-plated posts, whereas TMM-103-03-G-D uses gold-plated posts.

Q: Why do the TMM-103-03-T-D and TMM-103-03-TM-D variants have a lower maximum operating temperature?

A: These variants employ tin-plated contact finishes on both mating and post surfaces, which establish a maximum operating temperature of -55°C to 105°C. The gold-plated variants (TMM-103-03-G-D and TMM-103-03-L-D) support extended operation to 125°C.

Q: Is the MTMM-103-03-G-D-150 cuttable feature compatible with standard PCB layouts designed for the original 57102-G08-03LF?

A: Yes. The cuttable feature allows individual position separation after assembly, but the connector maintains standard 0.079" (2.00mm) pitch spacing and through-hole mounting compatibility. The contact length is slightly shorter (0.150" versus 0.157" mating contact length), but this does not affect PCB footprint compatibility.

Q: Are all substitute parts REACH compliant?

A: The Samtec substitutes (MTMM-103-03-G-D-150, TMM-103-03-G-D, TMM-103-03-L-D, TMM-103-03-T-D, TMM-103-03-TM-D) are REACH Unaffected. The original Amphenol ICC 57102-G08-03LF is REACH Affected. Both compliance statuses are acceptable for most applications; verify specific regulatory requirements for your end-use application.
