TMM-110-02-L-S Equivalent & Substitute Parts

Part Overview

The TMM-110-02-L-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 10-position, single-row connector operates at 2.00mm pitch and supports 3.2A per contact with an operating temperature range of -55°C to 125°C. The part is currently active in production and RoHS3 compliant. Equivalent parts are identified when applications require alternative sourcing, inventory availability, or specific performance characteristics within the allowed electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

The NRPN101PAEN-RC from Sullins Connector Solutions qualifies as a substitute for the TMM-110-02-L-S based on the following critical parameters:

• Pitch Compatibility: Both parts maintain 0.079" (2.00mm) mating pitch, ensuring mechanical and electrical interchangeability at the board level
• Position Count: Both feature 10 positions in a single row, maintaining identical footprint and contact arrangement
• Connector Architecture: Both are unshrouded headers with male pin contacts, square contact geometry, and through-hole solder termination
• Fastening Mechanism: Both employ push-pull fastening type for consistent mating force and retention
• Compliance: Both are RoHS3 compliant and carry EAR99 ECCN classification
• Contact Material & Finish: Both utilize gold-plated mating surfaces suitable for signal and power applications

Substitution is valid within the intersection of electrical and mechanical operating parameters. Differences in contact current rating, operating temperature range, and insulation material do not preclude substitution when application requirements fall within the lower-rated part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TMM-110-02-L-S and NRPN101PAEN-RC are active production parts with RoHS3 compliance and EAR99 classification. Selection between these parts depends on application-specific electrical and thermal requirements:

• TMM-110-02-L-S: Select when applications require the extended operating temperature range (-55°C to 125°C) or higher current capacity (3.2A per contact). LCP insulation material provides superior thermal and chemical resistance.

• NRPN101PAEN-RC: Select when applications operate within -40°C to 105°C and current requirements do not exceed 2A per contact. This part offers equivalent mechanical interchangeability with specified voltage rating of 150V.

Both parts maintain identical pitch, position count, contact geometry, and fastening mechanism, ensuring direct footprint compatibility on PCB designs. Inventory availability and lead time may also influence selection between active production alternatives.

Frequently Asked Questions (FAQ)

Q: Can NRPN101PAEN-RC replace TMM-110-02-L-S in all applications?

A: Substitution is valid when application current requirements do not exceed 2A per contact and operating temperature remains within -40°C to 105°C. The 0.079" (2.00mm) pitch and 10-position single-row configuration ensure mechanical interchangeability. Verify application specifications against the lower-rated part's electrical limits before substitution.

Q: What are the key mechanical compatibility factors?

A: Both connectors share identical pitch (2.00mm), position count (10), row configuration (1), contact shape (square), and through-hole solder termination. Push-pull fastening type is consistent across both parts. PCB footprint and mating interface are directly compatible.

Q: How do insulation materials differ between these parts?

A: TMM-110-02-L-S uses Liquid Crystal Polymer (LCP), while NRPN101PAEN-RC uses Polyamide (PA6T) Nylon 6T. Both materials are suitable for standard board-to-board and cable applications. LCP provides enhanced thermal stability and chemical resistance at elevated temperatures.

Q: Are there voltage or current limitations for substitution?

A: TMM-110-02-L-S supports 3.2A per contact with unspecified voltage rating. NRPN101PAEN-RC supports 2A per contact at 150V. Applications must operate within the lower-rated part's specifications. If application current exceeds 2A per contact, TMM-110-02-L-S is required.

Q: What is the temperature operating range difference?

A: TMM-110-02-L-S operates from -55°C to 125°C. NRPN101PAEN-RC operates from -40°C to 105°C. Applications requiring extended low-temperature operation below -40°C or high-temperature operation above 105°C require TMM-110-02-L-S.

Q: Are both parts RoHS3 compliant?

A: Yes, both TMM-110-02-L-S and NRPN101PAEN-RC are RoHS3 compliant and carry EAR99 ECCN classification, meeting regulatory requirements for commercial and industrial applications.
