Engineering Selection Recommendations

Direct Replacement (Recommended for Existing Designs):

The 57102-F08-04LF is the primary substitute for the obsolete 57102-F08-04. Both parts are manufactured by Amphenol ICC and share identical electrical and mechanical specifications. The LF variant is active in production and RoHS compliant, making it suitable for new procurement and design continuity. This substitution requires no circuit board redesign or connector interface modification.

Alternative Substitutes (Samtec MTMM Series):

The Samtec MTMM-104 series provides functional equivalents with the following considerations:

MTMM-104-02-G-D-150 and MTMM-104-02-G-D-155 feature shorter overall contact lengths (0.255" vs. 0.335") and reduced post lengths (0.041" to 0.046" vs. 0.118"), suitable for applications with limited PCB thickness or space constraints. These parts maintain gold mating contacts and support 3A current rating with extended operating temperature range (-55°C to 125°C).

MTMM-104-03-G-D-157 and MTMM-104-03-T-D-155 provide intermediate contact lengths (0.302" overall) with post lengths of 0.086" to 0.088", offering a middle ground between compact and standard configurations.

MTMM-104-04-F-D-157, MTMM-104-04-G-D-155-001, and MTMM-104-04-G-D-157 feature the longest overall contact lengths (0.323") and post lengths (0.107" to 0.109"), approaching the original 57102-F08-04 dimensions. MTMM-104-04-G-D-157 is the closest dimensional match with gold mating contacts and full 8-position loading.

All Samtec alternatives are ROHS3 compliant and active in production. Contact length variations accommodate different PCB thicknesses and mechanical clearance requirements. Selection depends on specific board layout constraints and thermal operating requirements.

Compliance Considerations:

The original 57102-F08-04 is RoHS non-compliant. All substitute parts listed are RoHS compliant (57102-F08-04LF) or ROHS3 compliant (Samtec MTMM series), meeting current regulatory requirements for new designs and production.

Frequently Asked Questions (FAQ)

Q: Can I use MTMM-104 series parts as direct replacements for the 57102-F08-04?

A: MTMM-104 series parts are functionally equivalent but not direct pin-for-pin replacements. They maintain the same 2.00mm pitch, 8-position 2-row configuration, and through-hole solder termination. However, contact length variations require PCB design verification. The 57102-F08-04LF is the true direct replacement from Amphenol ICC.

Q: What is the difference between the various MTMM-104 part numbers?

A: MTMM-104 part numbers encode specific contact configurations. The second digit (02, 03, 04) indicates contact length class. The letter following indicates contact finish (G = Gold, S = Silver, T = Tin, F = Flash). The final digits specify mating contact length in thousandths of an inch. For example, MTMM-104-02-G-D-150 has 0.150" mating contact length with gold finish.

Q: Are Samtec MTMM parts cuttable?

A: Yes, Samtec MTMM series headers are cuttable, allowing customization to fewer positions if required. The 57102-F08-04 and 57102-F08-04LF are not cuttable. This feature provides design flexibility for applications requiring non-standard position counts.

Q: What is the significance of the "-001" suffix in MTMM-104-04-G-D-155-001?

A: The "-001" suffix indicates this variant has 7 positions loaded instead of the standard 8. This part is suitable only for applications specifically designed for 7-position headers and should not be used as a general substitute for the 8-position 57102-F08-04.

Q: How do contact length variations affect PCB design?

A: Contact length determines how deeply the header penetrates the PCB. Shorter post lengths (MTMM-104-02 series at 0.041" to 0.046") suit thin PCBs or surface-mounted applications. Longer post lengths (MTMM-104-04 series at 0.107" to 0.109") accommodate thicker boards. The original 57102-F08-04 post length is 0.118" (3.00mm). Verify PCB thickness compatibility before substitution.

Q: What is the difference between gold and tin contact finishes?

A: Gold finishes (G designation) provide superior corrosion resistance and lower contact resistance, suitable for high-reliability applications. Tin finishes (T designation) offer cost efficiency and adequate performance for standard industrial applications. Both finishes are compatible with standard solder termination processes.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 57102-F08-04LF is RoHS compliant. All Samtec MTMM-104 series parts listed are ROHS3 compliant. The original 57102-F08-04 is RoHS non-compliant, making substitution necessary for new designs subject to RoHS regulations.

Q: What is the current rating difference between the original part and substitutes?

A: The 57102-F08-04 is rated for 2A at 200V. All Samtec MTMM-104 substitutes are rated for 3A with no specified voltage rating in the provided data. The higher current rating of MTMM parts provides additional design margin for power distribution applications.

Q: Can I mix contact finishes within a single connector assembly?

A: The provided data specifies uniform contact finishes per part number. Mixing finishes (e.g., gold mating with tin posts) is not recommended without explicit design validation, as it may affect contact resistance and reliability characteristics.
