MTMM-101-02-T-S-000 Equivalent & Substitute Parts
Part Overview
The MTMM-101-02-T-S-000 is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This single-position, unshrouded header features male pins with phosphor bronze contacts finished in tin and is housed in liquid crystal polymer (LCP) insulation. The part is active in production and ROHS3 compliant, making it suitable for modern electronic assemblies requiring reliable interconnection in operating temperatures from -55°C to 105°C.
Equivalent and substitute parts within the MTMM series are necessary when design requirements specify different contact engagement lengths, overall connector heights, or mating contact depths to accommodate varying PCB stack-up configurations or connector receptacle specifications.

Substitute Part Grouping Explanation
Substitution within the MTMM-101 series is determined by the following critical parameters:
Contact Length - Mating: The depth of contact engagement into a mating receptacle. This parameter directly affects compatibility with specific connector receptacles and PCB stack-up requirements.
Contact Length - Post: The length of the solder post extending below the insulation body. This parameter determines solder joint formation depth and PCB hole engagement.
Overall Contact Length: The total length from the tip of the mating contact to the end of the solder post. This parameter defines the physical envelope and determines compatibility with specific board-to-board spacing and receptacle designs.
All substitute parts maintain identical specifications for:
- Single position, single row configuration
- Male pin contact type with square shape
- Phosphor bronze material with tin finish
- Liquid crystal polymer insulation
- Through-hole solder termination
- 3A current rating
- -55°C to 105°C operating temperature range
- UL94 V-0 flammability rating
- ROHS3 compliance
- MSL 1 rating
Variations in contact engagement and post lengths allow selection based on specific mating receptacle requirements and PCB assembly constraints.

Engineering Selection Recommendations
All listed substitute parts are active products manufactured by Samtec Inc. and maintain ROHS3 compliance with UL94 V-0 flammability certification. Selection among equivalent parts depends on matching the required contact engagement depth and solder post length to the specific mating receptacle design and PCB assembly configuration.
Parts sharing the same overall contact length (0.255", 0.302", 0.323", 0.377", or 0.456") are mechanically interchangeable within their respective height groups, provided the contact engagement and post lengths align with receptacle specifications.
All parts maintain identical electrical performance characteristics: 3A current rating, -55°C to 105°C operating temperature range, phosphor bronze contacts with tin finish, and liquid crystal polymer insulation.
Frequently Asked Questions (FAQ)
Q: What determines whether a substitute part is compatible with my application?
A: Compatibility is determined by three contact length parameters: mating contact length (engagement depth into receptacle), post length (solder joint formation), and overall contact length (physical envelope). The mating contact length must match the receptacle design, and the overall contact length must fit the board-to-board spacing requirement.
Q: Can I use MTMM-101-02-T-S-070 as a substitute for MTMM-101-02-T-S-000?
A: Both parts share the same overall contact length of 0.255" (6.48mm) and identical insulation height. They differ in contact engagement and post lengths. Substitution is valid only if the mating receptacle specifications match the 0.070" (1.78mm) engagement depth of the -070 variant.
Q: What is the difference between parts with 0.255" and 0.377" overall contact lengths?
A: The 0.377" overall length provides greater solder post extension and mating contact depth compared to the 0.255" length. Selection depends on PCB stack-up thickness and receptacle design requirements. These are not interchangeable due to physical envelope differences.
Q: Are all substitute parts ROHS3 compliant?
A: Yes, all listed substitute parts maintain ROHS3 compliance and UL94 V-0 flammability certification, consistent with the primary part MTMM-101-02-T-S-000.
Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?
A: MSL 1 indicates the component has unlimited shelf life without moisture bake-out requirements. All listed parts carry this rating, eliminating moisture-related handling constraints during assembly.
Q: Can I substitute parts with different overall contact lengths?
A: No. Overall contact length determines the physical envelope and board-to-board spacing compatibility. Parts with different overall lengths (0.255", 0.302", 0.323", 0.377", 0.456") are not interchangeable and must be selected based on specific design requirements.
