TMM-108-01-TM-D-SM Equivalent & Substitute Parts

Part Overview

The TMM-108-01-TM-D-SM is a surface mount rectangular connector header manufactured by Samtec Inc. This 16-position, 2-row connector with 2.00mm pitch is designed for board-to-board or cable applications. The part is currently active in production with 788 units in stock. Alternative equivalent parts become necessary when supply constraints occur, specific contact finishes are required, or when design requirements call for different electrical ratings or operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMM-108-01-TM-D-SM is determined by the following critical parameters:

• Connector Configuration: 16-position, 2-row header with 2.00mm pitch and 2.00mm row spacing
• Mounting and Termination: Surface mount with solder termination
• Fastening Mechanism: Push-pull fastening type
• Insulation Height: 0.059" (1.50mm)
• Contact Shape: Square
• Shrouding: Unshrouded
• Regulatory Compliance: ROHS3 compliant, UL94 V-0 flammability rating

The substitute parts NRPN082MAMP-RC and NRPN082MAMS-RC from Sullins Connector Solutions meet these core configuration requirements. Both parts maintain the same 16-position, 2-row 2.00mm pitch header format with surface mount solder termination and push-pull fastening. Both are ROHS3 compliant with UL94 V-0 flammability ratings.

Differences exist in contact material, contact finish, insulation material, current rating, operating temperature range, and voltage rating. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

TMM-108-01-TM-D-SM (Samtec) is the primary specification. Select this part when the application requires the extended low-temperature operating range (-55°C minimum) or when the higher current rating of 3.2A per contact is necessary.

NRPN082MAMP-RC (Sullins) includes a board guide feature and gold-plated contacts with flash thickness. This variant is suitable when enhanced contact reliability through gold plating is required and the operating temperature range of -40°C to 105°C is acceptable. The 2A current rating per contact must be verified against application requirements.

NRPN082MAMS-RC (Sullins) provides the same electrical and mechanical specifications as NRPN082MAMP-RC without the board guide feature. This variant is appropriate for applications where the board guide is not required and the 2A current rating per contact is sufficient.

All three parts are ROHS3 compliant and carry UL94 V-0 flammability ratings, meeting standard regulatory requirements. All maintain MSL 1 (Unlimited) moisture sensitivity levels.

Frequently Asked Questions (FAQ)

Q: Can NRPN082MAMP-RC or NRPN082MAMS-RC be used as direct replacements for TMM-108-01-TM-D-SM?

A: Both Sullins parts maintain the same 16-position, 2-row 2.00mm pitch configuration, surface mount termination, and push-pull fastening. However, the Samtec part specifies a 3.2A current rating per contact while the Sullins parts specify 2A. The Samtec part operates from -55°C to 105°C while the Sullins parts operate from -40°C to 105°C. Substitution is valid only when application current and temperature requirements fall within the Sullins specifications.

Q: What is the difference between NRPN082MAMP-RC and NRPN082MAMS-RC?

A: Both parts are electrically and mechanically identical. NRPN082MAMP-RC includes a board guide feature; NRPN082MAMS-RC does not. Select based on whether the board guide is required for your application.

Q: Why do the Sullins parts have gold-plated contacts while the Samtec part has tin-plated contacts?

A: Contact finish selection affects contact resistance, corrosion resistance, and long-term reliability characteristics. Gold plating provides superior corrosion resistance and lower contact resistance over extended service life. Tin plating is suitable for standard applications with adequate environmental protection.

Q: Are there voltage rating differences between these parts?

A: The Samtec TMM-108-01-TM-D-SM does not specify a voltage rating. The Sullins parts specify 150V. If your application requires voltage rating specification, the Sullins parts provide this parameter.

Q: Do these parts have different insulation materials?

A: Yes. The Samtec part uses Liquid Crystal Polymer (LCP) insulation; the Sullins parts use Polyamide (PA6T), Nylon 6T insulation. Both materials meet UL94 V-0 flammability requirements. Material selection may affect thermal performance and chemical resistance in specific environments.

Q: What is the significance of the contact length difference?

A: The Samtec part specifies 0.126" (3.20mm) mating contact length while the Sullins parts specify 0.141" (3.60mm). This 0.015" difference may affect mating force, insertion depth, and compatibility with specific receptacle designs. Verify receptacle compatibility before substitution.
