Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. Selection between TSW series (PBT insulation) and HTSW series (LCP insulation) depends on application-specific requirements related to insulation material properties.

TSW series parts (TSW-110-07-L-D-001, TSW-110-07-L-D-008, TSW-110-07-L-D-009, TSW-110-07-L-D-011, TSW-110-07-L-D-014, TSW-110-07-L-D-017, TSW-110-07-L-D-019, TSW-110-07-L-D-020) are direct equivalents with identical electrical and mechanical specifications. These parts carry Moisture Sensitivity Level 1 classification.

HTSW series parts (HTSW-110-07-L-D-006, HTSW-110-07-L-D-017) provide equivalent functionality with LCP insulation material and are not subject to MSL classification. The LCP material offers enhanced dimensional stability and chemical resistance compared to PBT.

All parts share identical contact geometry, pitch spacing, termination method, and temperature operating range, ensuring mechanical and electrical interchangeability within the specified parameter set.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically interchangeable with TSW-110-07-L-D-018?

A: Yes. All substitute parts maintain identical electrical specifications including contact type, pitch, number of positions, contact material, contact finish, and operating temperature range. Electrical interchangeability is confirmed across all listed parts.

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

A: The primary difference is insulation material. TSW series uses Polybutylene Terephthalate (PBT) with Black insulation color and carries Moisture Sensitivity Level 1 classification. HTSW series uses Liquid Crystal Polymer (LCP) with Natural insulation color and is not subject to MSL classification. All other electrical and mechanical parameters are identical.

Q: Can HTSW-110-07-L-D-006 and HTSW-110-07-L-D-017 be used as direct replacements for TSW-110-07-L-D-018?

A: Yes. HTSW parts are mechanically and electrically compatible with TSW parts. The insulation material difference does not affect mating compatibility or electrical performance. Selection should be based on application requirements for insulation material properties and MSL handling procedures.

Q: Are all substitute parts available in the same packaging options?

A: TSW-110-07-L-D-018 is supplied in standard packaging. Substitute parts are available in Bulk packaging. Packaging differences do not affect component functionality or performance.

Q: What parameters must remain constant for parts to be considered substitutes?

A: Critical parameters for substitutability include connector type (Header), contact type (Male Pin), number of positions (20), number of rows (2), pitch spacing (0.100" / 2.54mm), mounting type (Through Hole), termination method (Solder), contact geometry, contact finish specifications, contact material (Phosphor Bronze), operating temperature range (-55°C to 125°C), and flammability rating (UL94 V-0).

Q: Do all substitute parts meet ROHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of TSW-110-07-L-D-018.
