Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTSS-112-01-F-D is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins, 24 positions arranged in 2 rows
• Pitch & Spacing: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Physical Dimensions: Contact lengths, insulation height, and overall form factor
• Contact Materials & Finish: Phosphor bronze with gold mating finish and tin post finish
• Environmental Compliance: UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 rating
• Operating Range: -55°C to 125°C temperature specification

The substitute part TSS-112-01-F-D maintains equivalence across all critical electrical and mechanical parameters. The primary difference is the insulation material composition (Polybutylene Terephthalate vs. Liquid Crystal Polymer) and insulation color, which do not affect functional compatibility or performance in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HTSS-112-01-F-D and TSS-112-01-F-D maintain active product status with full ROHS3 compliance and UL94 V-0 flammability certification. Both parts carry MSL 1 rating, indicating unlimited shelf life under standard storage conditions.

The TSS-112-01-F-D substitute offers equivalent electrical and mechanical performance with identical contact configuration, pitch, mounting specifications, and environmental operating range. The insulation material difference (PBT versus LCP) does not affect functional compatibility or performance in standard board-to-board or cable connector applications.

Selection between these parts may be based on inventory availability, supply chain considerations, or specific design preferences regarding insulation material properties. Both parts are suitable for direct substitution in applications currently specified for the HTSS-112-01-F-D.

Frequently Asked Questions (FAQ)

Q: Are HTSS-112-01-F-D and TSS-112-01-F-D mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100"), position count (24), row configuration (2 rows), contact dimensions, shrouding design, and mounting specifications. They are mechanically interchangeable in board-to-board and cable applications.

Q: What is the functional difference between LCP and PBT insulation materials?

A: Both Liquid Crystal Polymer (LCP) and Polybutylene Terephthalate (PBT) are engineering thermoplastics meeting UL94 V-0 flammability requirements. Both materials support the identical -55°C to 125°C operating temperature range. Material selection typically reflects manufacturing process or design preference rather than functional performance differences in standard applications.

Q: Can I mix HTSS and TSS series connectors in the same assembly?

A: Yes. Both parts maintain identical electrical and mechanical specifications for mating surfaces, contact geometry, and pitch. They can be used interchangeably within the same assembly without affecting connector performance or reliability.

Q: Are both parts RoHS compliant?

A: Yes. Both HTSS-112-01-F-D and TSS-112-01-F-D are ROHS3 compliant with identical environmental certifications and MSL 1 moisture sensitivity ratings.

Q: What is the difference in insulation color between these parts?

A: The HTSS-112-01-F-D features natural (undyed) insulation, while the TSS-112-01-F-D features black insulation. This is a cosmetic difference with no impact on electrical or mechanical performance.

Q: Are both parts suitable for high-reliability applications?

A: Both parts carry UL94 V-0 flammability certification and maintain active product status with full compliance documentation. Selection for high-reliability applications should be based on specific application requirements and qualification protocols.
