Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with ROHS3 compliance and MSL rating 1. The TLW-103-05-H-S and TLW-103-05-G-S share the same TLW series designation, with the primary difference being contact finish specifications on the post. The MTLW-103-05-G-S-105 belongs to the MTLW series and includes documented UL94 V-0 flammability certification. Selection between these parts should be based on specific application requirements regarding contact finish specifications and flammability ratings where applicable.

Frequently Asked Questions (FAQ)

Q: Can MTLW-103-05-G-S-105 be used as a direct substitute for TLW-103-05-H-S?

A: Yes. Both parts share identical electrical and mechanical specifications including 3-position configuration, 0.100" (2.54mm) pitch, male pin contacts, through-hole mounting, phosphor bronze contact material, and LCP insulation. The MTLW series variant includes specified contact finish thicknesses and UL94 V-0 flammability rating.

Q: What is the difference between TLW-103-05-G-S and TLW-103-05-H-S?

A: Both parts are in the same TLW series with identical core specifications. The documented difference is in post contact finish thickness, where TLW-103-05-G-S specifies Flash thickness while TLW-103-05-H-S does not specify this parameter.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts maintain identical pitch (0.100" / 2.54mm), number of positions (3), contact shape (square), and through-hole mounting specifications, ensuring PCB footprint compatibility.

Q: What is the significance of the contact finish specifications?

A: Contact finish thickness affects electrical performance and durability. MTLW-103-05-G-S-105 specifies 10.0µin (0.25µm) mating finish and 3.00µin (0.076µm) post finish. TLW-103-05-G-S specifies 10.0µin (0.25µm) mating finish with Flash post finish. These variations may impact contact resistance and wear characteristics in specific applications.

Q: Do all parts meet the same temperature and current requirements?

A: Yes. All three parts are rated for -55°C to 125°C operating temperature and 5.2A per contact current rating.

Q: What does ROHS3 compliance mean for these parts?

A: ROHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive, restricting specific hazardous materials in electrical and electronic equipment.
