Engineering Selection Recommendations

All three parts—TLW-103-06-S-S, TLW-103-06-G-S, and MTLW-103-06-G-S-105—are active products from Samtec Inc. and maintain full ROHS3 compliance with MSL 1 rating. Selection among these parts is based on availability and specific contact finish requirements:

TLW-103-06-S-S and TLW-103-06-G-S differ in contact finish specifications. TLW-103-06-G-S provides documented contact finish thickness (10.0µin / 0.25µm on mating surface, Flash on post), while TLW-103-06-S-S does not specify finish thickness values. Both maintain identical electrical and mechanical performance.

MTLW-103-06-G-S-105 operates within the same electrical and mechanical parameters and includes UL94 V-0 material flammability rating. This part carries specified contact finish thickness on both mating (10.0µin / 0.25µm) and post (3.00µin / 0.076µm) surfaces.

All three parts are suitable for applications requiring 3-position, 0.100" pitch through-hole headers with 5.2A per contact current capacity and -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can TLW-103-06-G-S be used as a direct replacement for TLW-103-06-S-S?

A: Yes. Both parts share identical connector type, contact configuration, pitch, mounting method, and electrical ratings. The primary difference is documented contact finish thickness on TLW-103-06-G-S. Functional interchangeability is maintained for standard applications.

Q: What is the difference between TLW-103-06-G-S and MTLW-103-06-G-S-105?

A: Both parts maintain identical electrical and mechanical specifications. MTLW-103-06-G-S-105 belongs to the MTLW series and includes UL94 V-0 material flammability rating. Contact finish thickness specifications differ: TLW-103-06-G-S specifies Flash on the post, while MTLW-103-06-G-S-105 specifies 3.00µin (0.076µm).

Q: Are all three parts RoHS compliant?
