Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMMH-108-01-G-D-RA is determined by the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm) — must match exactly for mechanical compatibility
• Number of Positions: 16 — connector must accommodate identical pin count
• Number of Rows: 2 — row configuration must be identical
• Row Spacing - Mating: 0.079" (2.00mm) — inter-row distance must match
• Mounting Type: Through Hole, Right Angle — orientation and mounting method must be preserved
• Contact Type: Male Pin — gender must remain consistent
• Termination: Solder — connection method must be identical
• Operating Temperature Range: -55°C ~ 125°C — thermal performance must meet or exceed specification
• Material Flammability Rating: UL94 V-0 — safety compliance must be maintained
• RoHS Status: ROHS3 Compliant — regulatory compliance must be preserved

The substitute part 951216-7622-AR from 3M meets all critical substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the TMMH-108-01-G-D-RA and 951216-7622-AR maintain active product status and full compliance with ROHS3 regulations and UL94 V-0 flammability requirements. The 3M substitute part is available in higher inventory (1391 units) compared to the Samtec original (738 units), providing improved supply availability. Both components operate across the identical temperature range of -55°C to 125°C and share equivalent moisture sensitivity classification. Selection between these parts should be based on supply chain requirements, lead time considerations, and packaging preferences (Samtec supplied in Tube; 3M supplied in Bulk).

Frequently Asked Questions (FAQ)

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

A: Yes. Both connectors share identical mating pitch (0.079" / 2.00mm), position count (16), row configuration (2 rows), row spacing (0.079" / 2.00mm), mounting type (through-hole right-angle), and termination method (solder). Electrical and thermal performance specifications are equivalent.

Q: Are there differences in contact materials between these parts?

A: The TMMH-108-01-G-D-RA uses Phosphor Bronze contacts, while the 951216-7622-AR uses Copper Alloy contacts. Both materials are suitable for the specified operating temperature range and provide equivalent electrical performance for this connector class.

Q: What is the difference in packaging between these two parts?

A: The TMMH-108-01-G-D-RA is supplied in Tube packaging, while the 951216-7622-AR is supplied in Bulk packaging. This affects handling and storage procedures but does not impact electrical or mechanical compatibility.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the TMMH-108-01-G-D-RA and 951216-7622-AR are ROHS3 compliant, carry UL94 V-0 flammability ratings, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
