Substitute Part Grouping Explanation

Substitution eligibility for the TMM-120-01-G-S-RE is determined by strict equivalence across the following critical parameters:

• Manufacturer: Samtec Inc.
• Series: TMM
• Number of Positions: 20
• Pitch - Mating: 0.079" (2.00mm)
• Contact Type: Male Pin
• Termination: Solder
• Mounting Type: Through Hole, Right Angle
• Current Rating: 3.2A per Contact
• Operating Temperature: -55°C ~ 125°C
• Contact Finish - Mating: Gold
• Insulation Material: Liquid Crystal Polymer (LCP)
• RoHS Status: ROHS3 Compliant

The identified substitute part TMM-120-01-G-S-RA maintains all critical electrical and mechanical parameters, differing only in connector orientation designation within the same product family. Both parts are active production items from Samtec Inc. within the TMM series.

Parameter Comparison

Engineering Selection Recommendations

Both TMM-120-01-G-S-RE and TMM-120-01-G-S-RA are active production components from Samtec Inc. with full ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on specific board layout requirements and connector orientation needs within the application. Both parts maintain identical electrical performance specifications, current ratings, and operating temperature ranges. Inventory availability shows TMM-120-01-G-S-RA at 1119 pieces compared to TMM-120-01-G-S-RE at 977 pieces, which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can TMM-120-01-G-S-RA be used as a direct replacement for TMM-120-01-G-S-RE?

A: Yes. Both parts share identical electrical and mechanical specifications including pitch, contact count, current rating, operating temperature range, and contact materials. The designation difference reflects connector orientation variants within the same product family.

Q: Are there any differences in contact performance between these parts?

A: No. Both parts feature identical gold-plated phosphor bronze contacts with the same mating contact length (0.126"), post length (0.120"), and current rating (3.2A per Contact).

Q: Do both parts meet the same compliance standards?

A: Yes. Both TMM-120-01-G-S-RE and TMM-120-01-G-S-RA are ROHS3 compliant with Moisture Sensitivity Level 1 (MSL 1 for the main part; Not Applicable for the substitute), share the same ECCN classification (EAR99), and identical HTSUS codes (8536.69.4040).

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

A: The difference is indicated in the part number suffix: RE versus RA. This designation reflects the connector orientation configuration. Both maintain the same 20-position, 2.00mm pitch header design with through-hole, right-angle mounting.

Q: Are there any thermal or electrical performance differences?

A: No. Both parts operate across the identical temperature range (-55°C ~ 125°C) and carry the same current rating of 3.2A per contact with gold contact finishes.
