Engineering Selection Recommendations

All three parts—TLW-104-06-T-S-LL, TLW-104-06-T-S, and TLW-104-06-TM-S—are active production components manufactured by Samtec Inc. and maintain full ROHS3 compliance. Selection between these parts is based on availability and inventory levels rather than electrical or mechanical differences, as all parameters are identical.

TLW-104-06-T-S offers the highest inventory availability at 4382 units, making it the preferred choice for high-volume applications or when immediate procurement is required. TLW-104-06-TM-S provides 995 units in stock, and TLW-104-06-T-S-LL maintains 941 units. All parts are suitable for applications requiring 4-position through-hole headers with 2.54mm pitch spacing and 5.2A per contact current capacity across the -55°C to 105°C operating range.

Frequently Asked Questions (FAQ)

Q: Are TLW-104-06-T-S-LL, TLW-104-06-T-S, and TLW-104-06-TM-S electrically interchangeable?

A: Yes. All three parts share identical electrical specifications including 5.2A per contact current rating, phosphor bronze contact material, and tin plating. They are functionally equivalent for circuit design purposes.

Q: Do these parts have the same mechanical footprint?

A: Yes. All three parts feature identical mechanical dimensions: 4 positions, 0.100" (2.54mm) pitch, 0.105" (2.67mm) mating contact length, and 0.060" (1.52mm) insulation height. They are mechanically interchangeable on PCBs designed for the TLW series.

Q: What is the difference between these part numbers?

A: The differences are limited to internal Samtec designation codes within the part number suffix. All electrical, mechanical, and compliance specifications remain identical across the three variants.

Q: Are all parts ROHS3 compliant?

A: Yes. TLW-104-06-T-S-LL, TLW-104-06-T-S, and TLW-104-06-TM-S are all ROHS3 compliant with MSL rating 1 (Unlimited moisture sensitivity level).

Q: Which part should I select for new designs?

A: Selection should be based on current inventory availability and procurement lead times. TLW-104-06-T-S has the highest stock level (4382 units), making it the optimal choice for new designs requiring immediate availability.

Q: Are these parts suitable for high-temperature applications?
