Engineering Selection Recommendations

All three parts—TSW-104-22-S-S-RE, HTSW-104-22-S-S-RA, and TSW-104-22-S-S-RA—maintain Active product status and ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment for current applications.

The TSW-104-22-S-S-RE and TSW-104-22-S-S-RA share identical insulation material (PBT), insulation height (0.119"), and insulation color (Black), with both maintaining MSL 1 (Unlimited) moisture sensitivity classification. These two parts are functionally equivalent for direct substitution.

The HTSW-104-22-S-S-RA employs Liquid Crystal Polymer (LCP) insulation material with a slightly increased insulation height of 0.122" (3.10mm) and Natural insulation color. The MSL classification differs (Not Applicable versus Unlimited), reflecting the material composition difference. This part remains electrically and mechanically compatible but introduces material variation that may affect thermal and mechanical performance characteristics in specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can TSW-104-22-S-S-RA be used as a direct replacement for TSW-104-22-S-S-RE?

A: Yes. Both parts share identical connector type, contact configuration, pitch, number of positions, mounting type, termination method, contact finishes, contact material, operating temperature range, and flammability rating. The insulation material, height, and color are also identical, making this a direct functional equivalent.

Q: What is the difference between HTSW-104-22-S-S-RA and the TSW series parts?

A: The HTSW-104-22-S-S-RA uses Liquid Crystal Polymer (LCP) insulation instead of Polybutylene Terephthalate (PBT), resulting in a slightly higher insulation height (0.122" versus 0.119") and Natural insulation color instead of Black. The MSL classification is Not Applicable for HTSW versus MSL 1 (Unlimited) for TSW parts. All other electrical and mechanical parameters remain equivalent.

Q: Are all three parts ROHS3 compliant?

A: Yes. TSW-104-22-S-S-RE, HTSW-104-22-S-S-RA, and TSW-104-22-S-S-RA are all ROHS3 compliant, confirming lead-free construction and regulatory compliance for modern electronic assemblies.

Q: What is the operating temperature range for these connectors?

A: All three parts operate across -55°C to 125°C, meeting requirements for industrial and commercial temperature environments.

Q: Do these connectors have different current or voltage ratings?

A: Current and voltage ratings are not specified in the provided parameters for any of the three parts. Consult the manufacturer's detailed datasheets for application-specific electrical performance data.

Q: What is the pitch specification for these connectors?

A: All three parts feature 0.100" (2.54mm) pitch mating spacing, a standard configuration for board-to-board and cable interconnect applications.
