TMM-105-01-LM-S Equivalent & Substitute Parts

Part Overview

The TMM-105-01-LM-S is a 5-position rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This connector features a 2.00mm pitch, gold-plated mating contacts, and tin-plated posts, with a current rating of 3.2A per contact. The part is Active status and ROHS3 compliant, making it suitable for modern electronic assemblies requiring reliable interconnection solutions.

Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory constraints require alternative selection within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMM-105-01-LM-S is determined by strict equivalence across the following critical parameters:

• Manufacturer: Samtec Inc.
• Series: TMM
• Number of Positions: 5
• Pitch - Mating: 0.079" (2.00mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Current Rating: 3.2A per Contact
• Operating Temperature: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant

The substitute part TMM-105-01-L-S meets all these criteria, differing only in internal design characteristics that do not affect electrical or mechanical compatibility in the specified application context.

Parameter Comparison

Engineering Selection Recommendations

Both TMM-105-01-LM-S and TMM-105-01-L-S are Active status products manufactured by Samtec Inc. and maintain identical electrical and mechanical specifications across all critical parameters. Both parts are ROHS3 compliant and carry EAR99 classification, meeting regulatory requirements for modern electronic applications.

Selection between these parts should be based on inventory availability and lead time requirements, as they are functionally equivalent for all specified applications. The substitute part TMM-105-01-L-S offers higher current inventory levels (1345 Pcs vs. 754 Pcs), which may provide sourcing advantages in high-volume procurement scenarios.
