• Row spacing - mating: 0.079" (2.00mm)
• Connector type: Header with male pins
• Mounting type: Through hole
• Termination: Solder
• Fastening type: Push-pull
• Contact shape: Square
• Insulation material: Thermoplastic (LCP variant)
• Insulation height: 0.059" (1.50mm)
• Insulation color: Black
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)
• ECCN classification: EAR99
• HTSUS code: 8536.69.4040

These parameters define the core mechanical and electrical compatibility for board-to-board interconnection in this connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the 57102-F08-04LF and MTMM-104-02-G-D-150 are active products with full RoHS compliance. The Samtec substitute offers a higher current rating of 3A compared to the Amphenol ICC part's 2A rating, providing additional margin for applications within the same voltage and pitch specifications. Both components meet UL94 V-0 flammability requirements and maintain identical moisture sensitivity levels.

The primary differences lie in contact geometry and material composition. The Samtec part features a shorter overall contact length (0.255" versus 0.335") and uses phosphor bronze contacts with gold finish on both mating and post surfaces, whereas the Amphenol ICC part uses copper alloy with tin-finished posts. These differences do not affect mechanical or electrical compatibility for standard board-to-board interconnection applications operating within the specified electrical parameters.

Selection between these parts should be based on specific application requirements regarding contact length, post geometry, and material preferences rather than functional incompatibility.

Frequently Asked Questions (FAQ)

Q: Can MTMM-104-02-G-D-150 be used as a direct replacement for 57102-F08-04LF?

A: Yes, for applications requiring 8-position, 2-row, 2.00mm pitch board-to-board connections with through-hole solder termination and push-pull fastening. Both parts share identical pitch, row spacing, position count, and mechanical mounting characteristics. Verify that the shorter contact length (0.255" versus 0.335") and different post geometry of the Samtec part are compatible with your PCB design and mating connector specifications.

Q: What are the key differences between these two connectors?

A: The primary differences are contact length, contact material, and contact finish. The Samtec MTMM-104-02-G-D-150 has a shorter overall contact length and uses phosphor bronze with gold plating on both mating and post surfaces. The Amphenol ICC 57102-F08-04LF uses copper alloy with tin-finished posts. The Samtec part also provides a higher current rating of 3A versus 2A.

Q: Are there any packaging differences?

A: Yes. The Amphenol ICC part is supplied in box packaging, while the Samtec substitute is supplied in bulk packaging. This affects handling and storage procedures but does not impact component functionality.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and meet UL94 V-0 flammability requirements. The Samtec part carries ROHS3 compliance, while the Amphenol ICC part carries standard RoHS compliance. Both have MSL rating of 1 (Unlimited) and share identical ECCN and HTSUS classifications.

Q: What is the operating temperature range for these connectors?

A: The Samtec MTMM-104-02-G-D-150 operates from -55°C to 125°C. Operating temperature specifications are not provided for the Amphenol ICC 57102-F08-04LF in the available data.
