TMMH-108-01-F-D-RA Equivalent & Substitute Parts

Part Overview

The TMMH-108-01-F-D-RA is a 2mm low profile rectangular connector header manufactured by Samtec Inc. This through-hole, right-angle connector features 16 positions arranged in 2 rows with 0.079" (2.00mm) pitch and is designed for board-to-board or cable applications. The part is currently active in production with 1052 units in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMMH-108-01-F-D-RA is determined by strict alignment of the following critical parameters:

• Connector type: Header, through-hole, right-angle configuration
• Position count and row arrangement: 16 positions in 2 rows
• Mating pitch and row spacing: 0.079" (2.00mm) for both
• Contact type: Male pin
• Mounting method: Through-hole, right-angle
• Termination method: Solder
• Operating temperature range: -55°C ~ 125°C minimum
• Compliance: ROHS3 and UL94 V-0 flammability rating

The substitute part 951216-7622-AR (3M) meets all critical substitution criteria. Variations in contact length, insulation material composition, and contact finish thickness do not preclude functional equivalence in standard board-to-board applications where these parameters fall within acceptable design tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both the TMMH-108-01-F-D-RA and 951216-7622-AR are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. Both maintain identical operating temperature ranges (-55°C ~ 125°C) and moisture sensitivity levels (MSL 1, Unlimited). The parts are functionally equivalent for standard board-to-board connector applications where the specified pitch, position count, and mounting configuration are required. Selection between these parts may be based on availability, packaging preference (tube versus bulk), or established supplier relationships, as both meet the same regulatory and performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 951216-7622-AR be used as a direct replacement for the TMMH-108-01-F-D-RA?

A: Yes. Both parts share identical mating pitch (0.079" / 2.00mm), row spacing, position count (16 in 2 rows), contact type (male pin), mounting method (through-hole right-angle), and termination (solder). Both are ROHS3 compliant with UL94 V-0 flammability rating and operate across -55°C to 125°C.

Q: What are the differences between these two parts?

A: The primary differences are contact length dimensions and insulation material. The 3M part (951216-7622-AR) has longer mating contact length (0.173" versus 0.126") and longer post length (0.110" versus 0.092"). The Samtec part uses Liquid Crystal Polymer (LCP) insulation while the 3M part uses Thermoplastic. These differences do not affect functional compatibility in standard applications.

Q: Does packaging format affect compatibility?

A: No. The TMMH-108-01-F-D-RA is supplied in tube packaging while the 951216-7622-AR is supplied in bulk packaging. Packaging format is a logistics consideration only and does not affect electrical or mechanical compatibility.

Q: Are both parts currently available?

A: Yes. The TMMH-108-01-F-D-RA has 1052 units in stock, and the 951216-7622-AR has 1391 units in stock.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and carry UL94 V-0 material flammability rating. Both have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.
