Substitute Part Grouping Explanation

The TSW-150-27-T-S qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

• Connector Type & Contact Configuration: Both parts are unshrouded headers with male pins
• Position Count & Pitch: Identical 50-position configuration at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Both utilize through-hole mounting with solder termination
• Fastening Mechanism: Push-pull fastening type on both parts
• Contact Geometry: Matching contact length specifications (mating: 0.230", post: 1.000", overall: 1.330")
• Electrical & Thermal Performance: Identical operating temperature range (-55°C ~ 105°C) and UL94 V-0 flammability rating
• Compliance: Both parts maintain ROHS3 compliance and EAR99 classification

The primary difference between these parts is the insulation material composition and resulting insulation color, which does not affect electrical or mechanical compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HTSW-150-27-T-S and TSW-150-27-T-S maintain active product status with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on insulation material requirements specific to the application environment. The HTSW series utilizes Liquid Crystal Polymer (LCP) insulation, while the TSW series employs Polybutylene Terephthalate (PBT) insulation. Both materials support the identical operating temperature range and electrical specifications. Current inventory levels show 1165 units for HTSW-150-27-T-S and 917 units for TSW-150-27-T-S, with both parts available through standard procurement channels.

Frequently Asked Questions (FAQ)

Q: Are HTSW-150-27-T-S and TSW-150-27-T-S mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (50), contact geometry, mounting type (through-hole), and fastening mechanism (push-pull). They are mechanically interchangeable in standard board-to-board and cable applications.

Q: What is the functional difference between LCP and PBT insulation materials?

A: LCP (Liquid Crystal Polymer) and PBT (Polybutylene Terephthalate) are both UL94 V-0 rated materials suitable for the specified operating temperature range. Material selection depends on specific application requirements such as chemical resistance, dimensional stability, or environmental exposure. Both materials meet the electrical and thermal specifications for this connector category.

Q: Can I substitute TSW-150-27-T-S for HTSW-150-27-T-S in existing designs?

A: Substitution is permissible when the design does not specify insulation material as a critical parameter. The connectors are electrically and mechanically equivalent. Verify that the insulation color difference (natural vs. black) does not impact assembly or identification requirements in your application.

Q: Are both parts RoHS compliant?

A: Yes. Both HTSW-150-27-T-S and TSW-150-27-T-S are ROHS3 compliant and carry EAR99 export classification.

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

A: Both parts operate across -55°C to 105°C, supporting applications in industrial, automotive, and consumer electronics environments.
