The three substitute parts (HTSS-112-02-G-D, HTST-112-02-G-D, TST-112-02-G-D) maintain all critical electrical and mechanical parameters. Variations in insulation material (PBT vs. LCP), insulation color, and application style (Board to Board vs. Board to Cable/Wire) do not affect pin-level compatibility or mating interface performance.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. Selection between TSS-112-02-G-D and its substitutes depends on application-specific requirements:

TSS-112-02-G-D is suitable for board-to-board or cable applications with PBT insulation material and unlimited moisture sensitivity tolerance.

HTSS-112-02-G-D provides an alternative with LCP insulation material for enhanced thermal and chemical resistance, supporting both board-to-board and cable configurations.

HTST-112-02-G-D and TST-112-02-G-D are optimized for board-to-cable/wire applications. HTST-112-02-G-D uses LCP insulation with not-applicable MSL rating, while TST-112-02-G-D employs glass-filled PBT with specified 3.4A per contact current rating and unlimited MSL tolerance.

All parts share identical mating interface geometry, contact configuration, and environmental operating range, ensuring direct mechanical and electrical interchangeability within the specified parameter set.

Frequently Asked Questions (FAQ)

Q: Can TSS-112-02-G-D be directly replaced with HTSS-112-02-G-D?

A: Yes. Both parts maintain identical connector geometry, pin count, pitch, contact configuration, and mating interface dimensions. The primary difference is insulation material (PBT vs. LCP), which does not affect pin-level compatibility or board-level mounting.

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

A: Style designation indicates intended mating partner configuration. Board-to-board connectors mate with receptacle connectors on another PCB. Board-to-cable/wire connectors mate with cable or wire harness assemblies. All four parts maintain identical header pin geometry and can physically accommodate both application types.

Q: Are there electrical performance differences between substitute parts?

A: HTST-112-02-G-D and TST-112-02-G-D specify 3.4A per contact current rating. TSS-112-02-G-D and HTSS-112-02-G-D do not specify current rating in provided documentation. All parts use identical contact material (phosphor bronze) and gold plating specifications, ensuring equivalent electrical performance within rated parameters.

Q: Does insulation material affect compatibility?

A: Insulation material (PBT, LCP, or glass-filled PBT) affects thermal stability and chemical resistance but does not alter mating interface dimensions or electrical connectivity. Selection should reflect application environment and thermal requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four parts carry ROHS3 compliance certification, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the significance of Moisture Sensitivity Level (MSL)?

A: MSL rating indicates component sensitivity to moisture absorption during storage and handling. TSS-112-02-G-D, HTSS-112-02-G-D, and TST-112-02-G-D carry MSL 1 (Unlimited), indicating minimal moisture sensitivity. HTST-112-02-G-D carries Not Applicable rating. All parts are suitable for standard storage and assembly conditions.
