Engineering Selection Recommendations

All listed substitute parts maintain Active product status with ROHS3 compliance and UL94 V-0 flammability rating, ensuring regulatory consistency with the MTMM-111-12-G-D-000. Selection among substitute parts depends on application-specific contact geometry requirements:

Parts with shorter overall contact lengths (0.255" to 0.377") are suitable for applications requiring minimal board-to-board spacing or shallow mating depths. The MTMM-111-02-G-D series provides the most compact profile with 0.255" overall contact length.

Parts with intermediate overall contact lengths (0.456" to 0.555") accommodate standard PCB thicknesses and moderate mating depths. The MTMM-111-07-G-D and MTMM-111-10-G-D series offer flexibility in contact length distribution between mating and post segments.

The MTMM-111-12-G-D-000 with 0.614" overall contact length serves applications requiring extended post length for deeper board penetration or applications with thicker PCB assemblies.

All substitute parts share identical electrical ratings (3A current, -55°C to 125°C operating temperature) and mechanical specifications (22 positions, 2.00mm pitch, through-hole solder termination), ensuring functional interchangeability within the specified contact geometry parameters.

Frequently Asked Questions (FAQ)

Q: Can MTMM-111 series connectors be used interchangeably across different part numbers?

A: MTMM-111 series connectors are mechanically and electrically compatible when the 22-position, 2-row, 2.00mm pitch configuration is maintained. Substitution is valid when the application accommodates the specific contact length and overall height of the substitute part. Contact geometry differences determine suitability for specific PCB thicknesses and mating depths.

Q: What determines the choice between different contact length configurations?

A: Contact length selection is driven by PCB thickness, mating depth requirements, and available board space. Shorter overall contact lengths (0.255") suit compact applications with minimal spacing. Longer lengths (0.614" and above) accommodate thicker assemblies or applications requiring extended post penetration into the PCB.

Q: Are all MTMM-111-12-G-D-000 substitutes rated for the same current and temperature range?

A: Yes. All listed substitute parts maintain 3A current rating and -55°C to 125°C operating temperature range. Electrical performance is consistent across the series.

Q: Do substitute parts require different soldering procedures?

A: No. All substitute parts use identical solder termination and phosphor bronze contact material with gold finish. Standard through-hole soldering procedures apply uniformly across the MTMM-111 series.

Q: What is the significance of the contact length parameters in the part number?

A: The MTMM-111 part number structure encodes contact geometry specifications. Different numeric codes (02, 03, 05, 07, 10, 12) and suffix codes (070, 100, 130, 150, 160, 275, 305, 320) represent distinct contact length and post height combinations, allowing precise specification of connector geometry for application-specific requirements.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All MTMM-111 series parts listed are supplied in Bulk packaging, consistent with the MTMM-111-12-G-D-000 original specification.
