Engineering Selection Recommendations

All identified substitute parts maintain active product status with Samtec Inc. and comply with ROHS3 environmental standards. The TST series parts (TST-110-01-G-D-01, TST-110-01-G-D-03, TST-110-01-G-D-04, TST-110-01-G-D-11) are functionally equivalent to the TSS-110-01-G-D-01, with the primary distinction being insulation material composition—glass-filled PBT versus standard PBT. The HTST-110-01-G-D-04 variant employs Liquid Crystal Polymer (LCP) insulation material and is designated for high-temperature applications, maintaining identical electrical and mechanical interface specifications.

Selection among these parts should be based on application-specific requirements regarding insulation material properties and connector series designation. All parts share identical mating pitch, contact configuration, operating temperature range, and compliance certifications, ensuring direct functional interchangeability at the connector interface level.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the TSS-110-01-G-D-01?

A: Substitution is based on matching the core electrical and mechanical parameters: 20-position, 2-row header configuration with 0.100" (2.54mm) mating pitch and row spacing, through-hole solder termination, shrouded 4-wall design, push-pull fastening, gold-plated phosphor bronze contacts, and -55°C to 125°C operating temperature range.

Q: Are the TST series parts direct replacements for the TSS-110-01-G-D-01?

A: Yes. The TST-110-01-G-D-01, TST-110-01-G-D-03, TST-110-01-G-D-04, and TST-110-01-G-D-11 maintain identical mating interface specifications, contact configuration, and operating parameters. The primary difference is the insulation material composition (glass-filled PBT versus standard PBT), which does not affect connector interface compatibility.

Q: What is the difference between the TST and HTST series?

A: Both series share identical electrical and mechanical specifications for the 20-position, 2-row configuration. The HTST-110-01-G-D-04 uses Liquid Crystal Polymer (LCP) insulation material instead of PBT, providing different material properties while maintaining the same operating temperature range and contact interface.

Q: Can I use HTST-110-01-G-D-04 in place of TSS-110-01-G-D-01?

A: Yes. The HTST-110-01-G-D-04 is functionally equivalent at the mating interface, with identical pitch, position count, contact configuration, and operating temperature specifications. The LCP insulation material offers alternative material characteristics while preserving connector interface compatibility.

Q: Do all substitute parts have the same current rating?

A: The TSS-110-01-G-D-01 does not specify a current rating. The TST series parts and HTST-110-01-G-D-04 are rated at 3.4A per contact. This specification applies to the substitute parts and should be considered for application requirements.

Q: Are all these parts RoHS compliant?

A: Yes. All identified parts—TSS-110-01-G-D-01, TST-110-01-G-D-01, TST-110-01-G-D-03, TST-110-01-G-D-04, TST-110-01-G-D-11, and HTST-110-01-G-D-04—are ROHS3 compliant.
