TMM-108-02-L-S Equivalent & Substitute Parts

Part Overview

The TMM-108-02-L-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 8-position connector operates at 0.079" (2.00mm) pitch and supports 3.2A per contact across an operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct replacement in compatible applications.

Key Parameters

Substitute Part Grouping Explanation

The TMM-108-01-G-S qualifies as a substitute for the TMM-108-02-L-S based on the following critical parameters:

Both parts share the same base product number (TMM-108), manufacturer (Samtec Inc.), connector type (Header), contact type (Male Pin), number of positions (8), mating pitch (0.079" / 2.00mm), mounting type (Through Hole), termination method (Solder), contact material (Phosphor Bronze), insulation material (LCP), operating temperature range (-55°C ~ 125°C), current rating (3.2A per Contact), product status (Active), RoHS compliance (ROHS3), and MSL rating (1 / Unlimited).

Differences exist in contact finish specifications and contact length dimensions, which do not prevent functional substitution in applications where these variations are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the TMM-108-02-L-S and TMM-108-01-G-S are active products with identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Selection between these parts depends on application-specific requirements regarding contact finish specifications and contact length dimensions. The TMM-108-02-L-S features tin-plated posts with 10.0µin gold mating finish, while the TMM-108-01-G-S provides gold plating on both mating and post surfaces with increased mating finish thickness (20.0µin). Contact length variations between the two parts may affect insertion depth and mating force characteristics in specific connector housing designs.

Frequently Asked Questions (FAQ)

Q: Can TMM-108-01-G-S replace TMM-108-02-L-S in all applications?

A: Both parts share identical electrical ratings (3.2A per contact), operating temperature range (-55°C to 125°C), pitch (2.00mm), position count (8), and mounting method (through-hole solder). Substitution is valid where contact finish specifications and contact length dimensions do not impose design constraints.

Q: What are the key differences between these substitute parts?

A: The primary differences are contact finish composition and contact length dimensions. TMM-108-02-L-S uses tin-plated posts with 10.0µin gold mating finish, while TMM-108-01-G-S uses gold plating on both surfaces with 20.0µin mating finish thickness. Mating contact length differs by 0.020" (0.51mm), and post contact length differs by 0.020" (0.51mm).

Q: Are both parts RoHS compliant?

A: Yes, both TMM-108-02-L-S and TMM-108-01-G-S are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the current handling capacity of these connectors?

A: Both parts are rated for 3.2A per contact across the full operating temperature range of -55°C to 125°C.

Q: Do these parts require different PCB footprints?

A: Both parts maintain identical overall contact length (0.323" / 8.20mm), insulation height (0.059" / 1.50mm), and pitch (0.079" / 2.00mm), supporting the same PCB footprint design.
