Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMM-122-01-G-D-SM-M is determined by strict equivalence across the following critical parameters:

• Number of Positions: 44
• Number of Rows: 2
• Pitch - Mating: 0.079" (2.00mm)
• Row Spacing - Mating: 0.079" (2.00mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• 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
• Product Status: Active

The substitute part TMM-122-01-G-D-SM-P meets all these criteria, differing only in fastening type designation while maintaining full electrical and mechanical compatibility.
