Key Parameters

Substitute Part Grouping Explanation

The TSW-116-20-S-S qualifies as a direct substitute for the HTSW-116-20-S-S based on the following critical parameters:

• Connector Type & Contact Configuration: Both are male pin headers with identical 16-position, single-row configuration
• Pitch & Spacing: Both maintain 0.100" (2.54mm) mating pitch
• Mounting & Termination: Both are through-hole mounted with solder termination and push-pull fastening
• Contact Dimensions: Mating contact length (1.020"), post length (0.110"), and overall contact length (1.230") are identical
• Insulation Height: Both maintain 0.100" (2.54mm) insulation height
• Contact Geometry & Materials: Both feature square contact shape, phosphor bronze material, gold mating finish (30.0µin), and tin post finish
• Operating Temperature Range: Both rated -55°C ~ 125°C
• Compliance: Both are ROHS3 compliant with UL94 V-0 flammability rating

The primary difference lies in the insulation material composition and color, which does not affect electrical or mechanical compatibility for standard board-to-board or cable connection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HTSW-116-20-S-S and TSW-116-20-S-S are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

HTSW-116-20-S-S: Use when LCP insulation material is specified or preferred for applications requiring enhanced chemical resistance or specific thermal properties. Higher current inventory (977 units) supports immediate availability.

TSW-116-20-S-S: Use when PBT insulation material is acceptable or preferred. Suitable for cost-optimized designs where insulation material composition does not impact application performance. Adequate inventory (640 units) available.

Both parts maintain identical electrical and mechanical specifications for 16-position, 0.100" pitch through-hole header applications with -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Are HTSW-116-20-S-S and TSW-116-20-S-S mechanically interchangeable?

A: Yes. Both parts share identical contact dimensions, pitch spacing (0.100"), mounting type (through-hole), and overall form factor. They are mechanically interchangeable in board-to-board and cable connection applications.

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

A: LCP (Liquid Crystal Polymer) and PBT (Polybutylene Terephthalate) are both thermoplastic insulation materials rated UL94 V-0. The HTSW uses LCP insulation with natural color; the TSW uses PBT insulation with black color. Both materials meet the same flammability and thermal performance requirements for this connector series.

Q: Can I substitute TSW-116-20-S-S for HTSW-116-20-S-S in existing designs?

A: Yes, provided the design does not specify LCP insulation material as a requirement. The electrical and mechanical performance are equivalent across all critical parameters including contact finish, material composition, operating temperature range, and compliance certifications.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: connector type, contact type, number of positions and rows, mating pitch, mounting type, termination method, contact dimensions, insulation height, contact finish specifications, operating temperature range, and compliance certifications. Both parts match on all these parameters.

Q: Are both parts RoHS compliant?

A: Yes. Both HTSW-116-20-S-S and TSW-116-20-S-S are ROHS3 compliant and carry UL94 V-0 flammability certification.
