Engineering Selection Recommendations

Both the TSW-110-18-G-D and HTSW-110-18-G-D are active products manufactured by Samtec Inc. and maintain full ROHS3 compliance. Selection between these parts should be based on inventory availability and application-specific requirements regarding insulation material composition. The TSW-110-18-G-D utilizes PBT insulation with MSL 1 rating, while the HTSW-110-18-G-D employs LCP insulation with Not Applicable MSL classification. Both parts satisfy identical electrical and mechanical interface requirements and operate within the same temperature range with equivalent flammability ratings.

Frequently Asked Questions (FAQ)

Q: Can the HTSW-110-18-G-D be used as a direct replacement for the TSW-110-18-G-D?

A: Yes. Both parts share identical connector type, contact configuration, pitch spacing, mounting method, and contact dimensions. The difference in insulation material (PBT versus LCP) does not affect functional compatibility in standard through-hole solder applications.

Q: What is the significance of the different insulation materials?

A: The TSW-110-18-G-D uses Polybutylene Terephthalate (PBT) insulation, while the HTSW-110-18-G-D uses Liquid Crystal Polymer (LCP) insulation. Both materials meet UL94 V-0 flammability requirements and operate across the identical temperature range. Material selection may influence mechanical properties and environmental resistance, but electrical performance remains equivalent.

Q: Are there differences in moisture sensitivity between these parts?

A: The TSW-110-18-G-D carries an MSL rating of 1 (Unlimited), while the HTSW-110-18-G-D is classified as Not Applicable for MSL. This distinction reflects different material compositions but does not impact compatibility for standard board-level applications.

Q: Do both parts support the same solder termination process?

A: Yes. Both the TSW-110-18-G-D and HTSW-110-18-G-D are designed for solder termination through through-hole mounting and support identical soldering procedures.

Q: What are the key parameters that must match for substitution?

A: Critical parameters include connector type (Header), contact type (Male Pin), position count (20), row configuration (2 rows), pitch spacing (0.100"), mounting method (Through Hole), termination type (Solder), and all contact dimensions. Both substitute parts maintain these specifications.
