Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. Selection between TSS-112-01-SS-D and its substitutes is determined by application-specific requirements:

TSS-112-01-SS-D (Primary Part): PBT insulation material with black color. Suitable for general board-to-board or cable applications where insulation material preference aligns with PBT specifications.

HTSS-112-01-S-D: LCP insulation material with natural color. Applicable where liquid crystal polymer properties are required for enhanced thermal or chemical resistance compared to PBT.

HTST-112-01-S-D: LCP insulation material with natural color and board-to-cable/wire style. Rated for 3.4A per contact. Applicable for cable/wire termination applications requiring higher current capacity.

TSS-112-01-S-D: PBT insulation material with black color and 3A current rating. Applicable where current rating specification is required and PBT material is preferred.

TST-112-01-S-D: Glass-filled PBT insulation material with black color and board-to-cable/wire style. Rated for 3.4A per contact. Applicable for cable/wire termination applications requiring enhanced mechanical strength through glass reinforcement.

All parts share identical pitch, position count, contact geometry, operating temperature range, and flammability rating, ensuring direct mechanical and electrical interchangeability within their respective application categories.

Frequently Asked Questions (FAQ)

Q: Can TSS-112-01-SS-D be directly replaced with HTSS-112-01-S-D?

A: Yes. Both parts maintain identical electrical and mechanical interfaces, pitch, position count, contact geometry, and operating temperature range. The primary difference is insulation material (PBT versus LCP) and color (Black versus Natural). Direct substitution is supported from an interface perspective.

Q: What is the difference between board-to-board and board-to-cable/wire style connectors?

A: Style designation indicates the intended mating application. Board-to-board connectors mate with receptacle connectors on another PCB. Board-to-cable/wire connectors mate with cable or wire harness assemblies. TSS-112-01-SS-D, HTSS-112-01-S-D, and TSS-112-01-S-D support both styles. HTST-112-01-S-D and TST-112-01-S-D are designated for board-to-cable/wire applications.

Q: Are there current rating differences between substitute parts?

A: Yes. TSS-112-01-SS-D and HTSS-112-01-S-D do not specify current ratings. TSS-112-01-S-D is rated for 3A per contact. HTST-112-01-S-D and TST-112-01-S-D are rated for 3.4A per contact. Current rating selection depends on application power requirements.

Q: What is the significance of glass-filled PBT in TST-112-01-S-D?

A: Glass-filled PBT provides enhanced mechanical strength and rigidity compared to standard PBT. This material modification is applicable for applications requiring improved dimensional stability or mechanical durability in board-to-cable/wire configurations.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, ensuring regulatory conformance for applications subject to RoHS directives.

Q: What is the moisture sensitivity level (MSL) significance?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and does not require special storage or handling conditions. HTST-112-01-S-D is classified as Not Applicable, indicating it does not require MSL classification. Both classifications are acceptable for standard PCB assembly processes.
