Identified Substitutes:

TSW-105-08-S-D-RA and HTSW-105-08-S-D-RA and HTSW-105-08-SM-D-RA meet all critical electrical and mechanical parameters. Variations in insulation material (PBT versus Liquid Crystal Polymer) and insulation height do not affect functional compatibility in applications where the TSW-105-08-SS-D-RA is specified, as all parts maintain identical mating pitch, contact geometry, and electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts—TSW-105-08-S-D-RA, HTSW-105-08-S-D-RA, and HTSW-105-08-SM-D-RA—are active products with ROHS3 compliance and UL94 V-0 flammability certification. These parts maintain identical electrical and mechanical specifications for mating pitch, contact geometry, termination method, and operating temperature range.

TSW-105-08-S-D-RA shares the same series designation and insulation material (PBT) as the main part, differing only in contact finish specification details not affecting functional compatibility.

HTSW-105-08-S-D-RA and HTSW-105-08-SM-D-RA utilize Liquid Crystal Polymer (LCP) insulation material with increased insulation height (0.240" versus 0.219"), providing enhanced mechanical and thermal properties while maintaining all critical mating and electrical parameters.

Selection among these substitutes depends on application-specific requirements for insulation material properties and mechanical clearance constraints. All parts are suitable for direct replacement in applications where the TSW-105-08-SS-D-RA is specified.

Frequently Asked Questions (FAQ)

Q: Can TSW-105-08-S-D-RA be used as a direct replacement for TSW-105-08-SS-D-RA?

A: Yes. Both parts share identical mating pitch (0.100"), row spacing (0.100"), contact geometry, termination method, and operating temperature range (-55°C to 125°C). Both are ROHS3 compliant with UL94 V-0 flammability rating.

Q: What is the difference between the TSW and HTSW series substitutes?

A: The primary difference is insulation material. TSW-105-08-S-D-RA uses Polybutylene Terephthalate (PBT) with 0.219" insulation height. HTSW-105-08-S-D-RA and HTSW-105-08-SM-D-RA use Liquid Crystal Polymer (LCP) with 0.240" insulation height. All maintain identical mating pitch, contact specifications, and electrical performance.

Q: Are there any compatibility issues with PCB layout when substituting HTSW parts?

A: The increased insulation height of HTSW parts (0.240" versus 0.219") must be verified against PCB clearance specifications. Mating pitch and contact positioning remain identical, ensuring compatibility with standard 0.100" (2.54mm) grid layouts.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All identified substitutes are ROHS3 compliant and carry UL94 V-0 flammability certification. Operating temperature range is -55°C to 125°C across all parts.

Q: What is the difference in Moisture Sensitivity Level (MSL) between TSW and HTSW parts?

A: TSW-105-08-SS-D-RA and TSW-105-08-S-D-RA are rated MSL 1 (Unlimited). HTSW-105-08-S-D-RA and HTSW-105-08-SM-D-RA are rated MSL Not Applicable. This reflects material properties of the insulation material used in each series.

Q: Can HTSW-105-08-SM-D-RA and HTSW-105-08-S-D-RA be used interchangeably?

A: Yes. Both HTSW parts share identical electrical and mechanical specifications, including mating pitch, contact geometry, insulation height, and operating temperature range. Differences in part numbering reflect internal manufacturing or configuration variations that do not affect functional compatibility.
