Engineering Selection Recommendations

Both HTSW-104-24-L-S and TSW-104-24-L-S maintain active product status and comply with ROHS3 requirements. Selection between these parts depends on insulation material specifications:

HTSW-104-24-L-S is specified where Liquid Crystal Polymer (LCP) insulation material is required. LCP provides enhanced dimensional stability and chemical resistance in specific application environments.

TSW-104-24-L-S is specified where Polybutylene Terephthalate (PBT) insulation material is acceptable. PBT offers established performance characteristics across standard industrial applications and provides unlimited moisture sensitivity rating.

Both parts satisfy identical electrical and mechanical interface requirements, including contact geometry, pitch, operating temperature range, and flammability certification. The choice between these substitutes is determined by insulation material compatibility with the application environment and design specifications.

Frequently Asked Questions (FAQ)

Q: Can TSW-104-24-L-S replace HTSW-104-24-L-S in all applications?

A: TSW-104-24-L-S is mechanically and electrically compatible with HTSW-104-24-L-S. The primary difference is insulation material composition. Substitution is valid where PBT insulation material meets application requirements. Applications requiring LCP-specific properties must use HTSW-104-24-L-S.

Q: What is the significance of the insulation material difference?

A: HTSW-104-24-L-S uses Liquid Crystal Polymer (LCP) insulation, while TSW-104-24-L-S uses Polybutylene Terephthalate (PBT). Both materials achieve UL94 V-0 flammability rating. Material selection depends on chemical exposure, dimensional stability requirements, and environmental conditions specific to the application.

Q: Are the contact dimensions identical between these parts?

A: Yes. Both parts feature identical contact geometry, including mating contact length of 0.265" (6.73mm), post length of 0.115" (2.92mm), and overall contact length of 0.480" (12.19mm). Pitch spacing is 0.100" (2.54mm) for both parts.

Q: Do both parts support the same operating temperature range?

A: Yes. Both HTSW-104-24-L-S and TSW-104-24-L-S operate across -55°C to 125°C temperature range.

Q: What is the difference in moisture sensitivity levels?

A: HTSW-104-24-L-S has Not Applicable moisture sensitivity level, while TSW-104-24-L-S is rated MSL 1 (Unlimited). This indicates TSW-104-24-L-S has no moisture sensitivity restrictions for storage and handling.

Q: Are both parts RoHS compliant?

A: Yes. Both HTSW-104-24-L-S and TSW-104-24-L-S are ROHS3 compliant.
