TMM-107-02-L-S Equivalent & Substitute Parts

Part Overview

The TMM-107-02-L-S is a 7-position rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This unshrouded header features a 2.00mm pitch with male pin contacts and solder termination. The connector is actively produced and ROHS3 compliant, making it suitable for applications requiring reliable interconnection in standard industrial and commercial environments.

Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component selection from qualified manufacturers meeting equivalent electrical and mechanical specifications.

Substitute Part Grouping Explanation

The NRPN071PAEN-RC from Sullins Connector Solutions qualifies as a substitute for the TMM-107-02-L-S based on the following critical parameters:

Connector Configuration: Both parts are 7-position, single-row headers with 2.00mm mating pitch
Contact Type: Both feature male pin contacts with square geometry
Mounting and Termination: Both are through-hole mounted with solder termination
Electrical Compliance: Both are ROHS3 compliant and rated for EAR99 export classification
Mechanical Interface: Both are unshrouded headers designed for board-to-board or cable applications with push-pull fastening

Substitution is valid where the design accommodates the specified dimensional and electrical variations documented in the parameter comparison table.

Engineering Selection Recommendations

Both the TMM-107-02-L-S and NRPN071PAEN-RC are active products with ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on the following provided specifications:

Current Requirements: The TMM-107-02-L-S supports 3.2A per contact, while the NRPN071PAEN-RC is rated for 2A per contact. Applications requiring current levels above 2A per contact must use the Samtec part.

Operating Temperature Range: The TMM-107-02-L-S operates from -55°C to 125°C, while the NRPN071PAEN-RC operates from -40°C to 105°C. Applications requiring operation below -40°C or above 105°C require the Samtec part.

Dimensional Variations: The NRPN071PAEN-RC has a greater insulation height (2.00mm vs. 1.50mm) and slightly longer overall contact length (8.40mm vs. 8.20mm). PCB layout and mating connector clearances must accommodate these differences.

Contact Material and Finish: The TMM-107-02-L-S uses phosphor bronze with tin post finish, while the NRPN071PAEN-RC uses brass with gold post finish. Both configurations provide adequate electrical performance for standard applications.

Frequently Asked Questions (FAQ)

Q: Can the NRPN071PAEN-RC directly replace the TMM-107-02-L-S in all applications?

A: Direct replacement is valid only when the application operates within the NRPN071PAEN-RC specifications: current ≤ 2A per contact, operating temperature -40°C to 105°C, and PCB layout accommodates the increased insulation height and contact length variations.

Q: What are the critical dimensional differences between these connectors?

A: The NRPN071PAEN-RC has an insulation height of 2.00mm compared to 1.50mm for the TMM-107-02-L-S, and an overall contact length of 8.40mm versus 8.20mm. These differences may affect mating connector compatibility and PCB clearance requirements.

Q: Are both parts suitable for high-temperature applications?

A: The TMM-107-02-L-S supports operation to 125°C, making it suitable for extended high-temperature applications. The NRPN071PAEN-RC is limited to 105°C maximum operating temperature.

Q: What is the difference in current-carrying capacity?

A: The TMM-107-02-L-S is rated for 3.2A per contact, while the NRPN071PAEN-RC is rated for 2A per contact. Applications requiring higher current density must use the Samtec part.

Q: Are both parts RoHS compliant?

A: Yes, both the TMM-107-02-L-S and NRPN071PAEN-RC are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What packaging is available for these connectors?

A: Both parts are supplied in bulk packaging. Inventory availability should be verified with the respective manufacturers or authorized distributors.
