The TMS-118-01-S-D currently has 1052 units in stock, while the HTMS-118-01-S-D has 786 units available. Either part is functionally equivalent for board-to-board connector applications requiring 36-position, 0.050" pitch headers with 5A per contact current capacity.

Frequently Asked Questions (FAQ)

Q: What determines if HTMS-118-01-S-D can substitute for TMS-118-01-S-D?

A: Substitution is valid when all electrical and mechanical parameters match: pitch (0.050"), position count (36), row configuration (2 rows), row spacing (0.100"), contact type (male pin), mounting method (through hole), termination (solder), current rating (5A per contact), operating temperature range (-55°C ~ 125°C), and material certifications (UL94 V-0, ROHS3). The HTMS-118-01-S-D meets all these criteria.

Q: Are there any differences in physical dimensions between these parts?

A: No. Both parts share identical contact lengths, insulation height, overall contact length, and row spacing. Physical compatibility is confirmed across all measured dimensions.

Q: Do both parts have the same contact finish specifications?

A: Yes. Both parts feature gold-plated mating contacts (30.0µin thickness) and tin-plated posts, with phosphor bronze contact material and LCP insulation.

Q: What is the significance of the MSL rating for these connectors?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling. Standard storage conditions apply without special desiccant requirements.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: Yes. Identical pitch, position count, row spacing, and through-hole mounting specifications ensure direct PCB footprint compatibility. No design modifications are required for substitution.
