Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TMM-112-01-L-S-RE are qualified based on strict electrical and mechanical parameter equivalence within the TMM series. The substitution criteria are:

• Identical pitch (0.079" / 2.00mm mating pitch)
• Identical position count (12 positions, single row)
• Identical connector type (Header, Male Pin)
• Identical mounting method (Through Hole, Right Angle)
• Identical termination (Solder)
• Identical contact material and finish specifications
• Identical insulation material (LCP)
• Identical operating temperature range (-55°C ~ 125°C)
• Identical current rating (3.2A per Contact)
• Identical compliance status (ROHS3 Compliant)

The identified substitutes are TMM-112-01-L-S-RA and TMM-112-01-LM-S-RA, both from Samtec Inc. within the same TMM series. These parts maintain full electrical and mechanical compatibility with the main part while offering alternative availability and inventory positions.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TMM-112-01-L-S-RE, TMM-112-01-L-S-RA, and TMM-112-01-LM-S-RA—are active production parts from Samtec Inc. with ROHS3 compliance. Selection between these parts should be based on:

• Inventory availability: TMM-112-01-L-S-RA offers the highest stock level at 1020 pieces
• Moisture sensitivity requirements: TMM-112-01-L-S-RE and TMM-112-01-L-S-RA both carry MSL 1 rating; TMM-112-01-LM-S-RA is rated as Not Applicable
• Design timeline: All parts maintain identical electrical and mechanical specifications, allowing direct substitution without circuit redesign

Frequently Asked Questions (FAQ)

Q: Can TMM-112-01-L-S-RA be used as a direct replacement for TMM-112-01-L-S-RE?

A: Yes. Both parts share identical electrical and mechanical parameters including pitch (2.00mm), position count (12), contact material, finish specifications, operating temperature range (-55°C ~ 125°C), and current rating (3.2A per contact). Both are ROHS3 compliant and carry MSL 1 rating.

Q: What is the difference between TMM-112-01-L-S-RE and TMM-112-01-LM-S-RA?

A: The parts are electrically and mechanically equivalent across all specified parameters. The primary difference is the moisture sensitivity level designation: TMM-112-01-L-S-RE carries MSL 1 (Unlimited), while TMM-112-01-LM-S-RA is rated as Not Applicable. Both maintain identical contact specifications, insulation material (LCP), and operating characteristics.

Q: Are all substitute parts suitable for high-temperature applications?

A: Yes. All three parts operate within the -55°C to 125°C temperature range and are constructed with identical materials: Phosphor Bronze contacts with gold mating finish and LCP insulation. This specification applies uniformly across TMM-112-01-L-S-RE, TMM-112-01-L-S-RA, and TMM-112-01-LM-S-RA.

Q: What is the mating pitch for these connectors?

A: The mating pitch is 0.079 inches (2.00mm) for all three parts. This specification is critical for PCB layout and mating connector selection.

Q: Are these parts RoHS compliant?

A: Yes. All three parts—TMM-112-01-L-S-RE, TMM-112-01-L-S-RA, and TMM-112-01-LM-S-RA—are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing.
