Substitute Part Grouping Explanation

The TMM-112-01-G-D-SM-P is classified as a direct substitute for the TMM-112-01-G-D-SM-M based on the following critical parameters that determine functional equivalence:

• Connector Configuration: Both parts maintain identical 24-position, 2-row header layout with 0.079" (2.00mm) pitch and row spacing
• Electrical Characteristics: Matching 3.2A per contact current rating and identical contact material (Phosphor Bronze) with gold finish
• Mechanical Compatibility: Identical contact length (0.126" / 3.20mm mating), insulation height (0.059" / 1.50mm), and contact shape (Square)
• Environmental Specifications: Identical operating temperature range (-55°C ~ 125°C) and material flammability rating (UL94 V-0)
• Compliance: Both parts are ROHS3 compliant with matching ECCN and HTSUS classifications
• Manufacturing Standards: Both feature identical surface mount termination, push-pull fastening, and pick-and-place capability

The substitution is valid across all specified electrical and mechanical parameters. The difference between these parts is limited to packaging format (Tube for both) and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both TMM-112-01-G-D-SM-M and TMM-112-01-G-D-SM-P are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 material certification. Selection between these parts should be based on inventory availability and lead time requirements, as all electrical, mechanical, and environmental specifications are identical. The TMM-112-01-G-D-SM-M currently has higher inventory (824 units) compared to TMM-112-01-G-D-SM-P (649 units). Both parts are suitable for applications requiring 24-position, 2-row surface mount headers with 2.00mm pitch spacing and 3.2A per contact current capacity across the -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Are TMM-112-01-G-D-SM-M and TMM-112-01-G-D-SM-P electrically interchangeable?

A: Yes. Both parts have identical electrical specifications including 3.2A per contact current rating, contact material (Phosphor Bronze), and gold finish thickness. They are direct electrical equivalents.

Q: Do these parts have the same physical footprint?

A: Yes. Both parts maintain identical mechanical dimensions: 24 positions in 2 rows, 0.079" (2.00mm) pitch and row spacing, 0.126" (3.20mm) mating contact length, and 0.059" (1.50mm) insulation height. They are mechanically interchangeable on PCB layouts.

Q: What is the difference between these two part numbers?

A: The parts are functionally equivalent across all specified parameters. The difference is limited to inventory availability and potential packaging or manufacturing batch variations not detailed in the provided specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both TMM-112-01-G-D-SM-M and TMM-112-01-G-D-SM-P are ROHS3 compliant and meet UL94 V-0 material flammability requirements.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across -55°C to 125°C, suitable for industrial and commercial temperature environments.

Q: Can these parts be used in high-current applications?

A: Each contact is rated for 3.2A. Total current capacity depends on the number of contacts utilized. For 24-position headers with all contacts loaded, maximum current would be 76.8A distributed across all contacts.
