TMM-109-01-G-D-RE Equivalent & Substitute Parts

Part Overview

The TMM-109-01-G-D-RE is a 2MM terminal strip connector header manufactured by Samtec Inc. This through-hole, right-angle rectangular connector features 18 positions arranged in 2 rows with 0.079" (2.00mm) pitch spacing. The connector is designed for board-to-board or cable applications with solder termination and push-pull fastening. The part is currently active in production with 969 units in stock. Substitute parts may be required due to inventory constraints, lead time considerations, or specific application requirements within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMM-109-01-G-D-RE is determined by strict equivalence across the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 18
• Number of Rows: 2
• Pitch - Mating: 0.079" (2.00mm)
• Row Spacing - Mating: 0.079" (2.00mm)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Length - Mating: 0.126" (3.20mm)
• Contact Length - Post: 0.120" (3.05mm)
• Insulation Height: 0.155" (3.94mm)
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature: -55°C ~ 125°C
• Current Rating: 3.2A per Contact
• Insulation Color: Black
• RoHS Status: ROHS3 Compliant

The substitute part TMM-109-01-G-D-RA meets all these critical parameters and is therefore electrically and mechanically equivalent for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the TMM-109-01-G-D-RE and TMM-109-01-G-D-RA are active products manufactured by Samtec Inc. and carry ROHS3 compliance certification. The parts are electrically and mechanically equivalent across all specified parameters. Selection between these parts should be based on inventory availability and lead time requirements. Both parts maintain identical electrical performance characteristics, mechanical dimensions, and environmental operating specifications. The MSL rating difference (1 vs. Not Applicable) does not affect substitution eligibility, as both parts meet the moisture sensitivity requirements for their respective packaging and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can TMM-109-01-G-D-RA be used as a direct replacement for TMM-109-01-G-D-RE?

A: Yes. Both parts are electrically and mechanically equivalent. All critical parameters including connector type, position count, pitch spacing, contact materials, finish specifications, and operating temperature ranges are identical.

Q: Are there any dimensional differences between these parts?

A: No. The contact lengths, insulation height, pitch spacing, and row spacing are identical between both parts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TMM-109-01-G-D-RE and TMM-109-01-G-D-RA are ROHS3 compliant and carry the same EAR99 ECCN classification.

Q: What is the difference between the part numbers?

A: The part numbers differ only in the suffix designation (RE vs. RA). All other specifications, including the base product number TMM-109, are identical.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -55°C to 125°C.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. The mechanical footprint, mounting type (through-hole, right-angle), and all dimensional specifications are identical, allowing direct PCB layout compatibility.
