TLW-104-01-L-S-RA Equivalent & Substitute Parts

Part Overview

The TLW-104-01-L-S-RA is an active Samtec Inc. rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This 4-position, single-row connector operates within the -55°C to 125°C temperature range and is RoHS3 compliant with MSL 1 rating. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within the Flex Stack TLW series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the TLW-104 series is determined by the following critical parameters: connector type (header), contact type (male pin), number of positions (4), pitch (0.100" / 2.54mm), mounting configuration (through hole, right angle), termination method (solder), and fastening type (push-pull). The TLW-104-01-L-S-RA and TLW-104-01-G-S-RA share identical values across all these parameters, establishing direct substitutability. Both parts maintain the same operating temperature range, current rating, RoHS3 compliance, and MSL 1 rating. The primary distinction between these parts is the contact finish specification on the post termination.

Parameter Comparison

Engineering Selection Recommendations

Both TLW-104-01-L-S-RA and TLW-104-01-G-S-RA are active products with ROHS3 compliance and MSL 1 rating. Selection between these parts should be based on post finish specifications. The TLW-104-01-G-S-RA provides documented contact finish thickness values (10.0µin / 0.25µm on mating surface, flash on post) and explicit gold finish designation on the post termination. The TLW-104-01-L-S-RA does not specify these finish parameters. For applications requiring documented finish specifications or where post contact finish is a design requirement, TLW-104-01-G-S-RA is the appropriate selection. Both parts maintain identical electrical performance, mechanical dimensions, and environmental ratings.

Frequently Asked Questions (FAQ)

Q: Are TLW-104-01-L-S-RA and TLW-104-01-G-S-RA mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (through hole, right angle), position count (4), pitch (0.100" / 2.54mm), and physical dimensions including contact lengths and insulation height.

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

A: The primary difference is the contact finish specification on the post termination. TLW-104-01-G-S-RA specifies gold finish with flash thickness on the post, while TLW-104-01-L-S-RA does not provide post finish specifications.

Q: Can these connectors be used in the same PCB design without modification?

A: Yes. Both parts are within the Flex Stack TLW series with identical electrical ratings (5.2A per contact), operating temperature range (-55°C to 125°C), and mechanical specifications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both TLW-104-01-L-S-RA and TLW-104-01-G-S-RA are ROHS3 compliant with MSL 1 rating.

Q: Which part should be selected for new designs?

A: Selection depends on post finish requirements. If documented contact finish specifications are required, TLW-104-01-G-S-RA is recommended. Both parts are active products suitable for new applications.
