TSW-110-14-S-S Equivalent & Substitute Parts

Part Overview

The TSW-110-14-S-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This unshrouded, single-row header accommodates 10 positions at 0.100" (2.54mm) pitch and features male pins with gold-plated mating contacts and tin-plated posts. The connector is currently in active product status and maintains full RoHS3 compliance with UL94 V-0 flammability rating.

Substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design requirements necessitate alternative connector configurations that maintain electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-110-14-S-S is determined by strict alignment of the following electrical and mechanical parameters:

• Pitch - Mating: 0.100" (2.54mm) — exact match required for PCB footprint compatibility
• Connector Type: Header with male pin contact type — ensures proper mating interface
• Mounting Type: Through Hole — maintains assembly process compatibility
• Termination: Solder — preserves connection reliability and manufacturing process
• Contact Finish - Mating: Gold — ensures signal integrity and corrosion resistance
• Insulation Material: Thermoplastic or equivalent — maintains structural integrity and flammability compliance
• Operating Temperature Range: Must encompass or match the -55°C ~ 125°C specification
• Material Flammability Rating: UL94 V-0 — required for safety compliance

The identified substitute part 4-102972-0 (TE Connectivity AMP Connectors AMPMODU Mod II series) shares these critical parameters, though it accommodates 40 positions rather than 10. This part may be used in applications where individual positions can be broken away or where the higher position count does not conflict with circuit design requirements.

Parameter Comparison

Engineering Selection Recommendations

The TSW-110-14-S-S remains the preferred selection for new designs due to its active product status and full RoHS3 compliance. The connector maintains a wider operating temperature range (-55°C to 125°C) compared to the substitute part, making it suitable for applications requiring extended thermal performance.

The substitute part 4-102972-0 carries obsolete product status, indicating discontinued manufacturing and limited future availability. Selection of this substitute should be limited to legacy system maintenance or applications where the 40-position breakaway configuration provides design advantages. The substitute part's operating temperature range (-65°C to 105°C) does not fully encompass the upper temperature specification of the main part, requiring thermal performance verification for applications approaching 105°C.

The substitute part's contact finish thickness on mating surfaces (15.0µin) is reduced compared to the main part (30.0µin), potentially affecting long-term contact reliability in high-cycle mating environments. The post finish composition differs (Tin-Lead versus Tin), which may impact soldering characteristics and long-term reliability depending on assembly process parameters.

Frequently Asked Questions (FAQ)

Q: Can the 4-102972-0 substitute directly replace the TSW-110-14-S-S in existing designs?

A: Direct replacement is not recommended without design review. While both connectors share the same 0.100" (2.54mm) pitch and through-hole mounting, the substitute accommodates 40 positions versus 10. PCB footprint compatibility must be verified. The reduced insulation height (0.090" versus 0.100") and lower contact finish thickness on mating surfaces require assessment for your specific application.

Q: What are the key compatibility criteria for these connectors?

A: Compatibility is determined by pitch (0.100" / 2.54mm), connector type (header with male pins), mounting method (through-hole solder termination), and contact finish (gold-plated mating surfaces). Both parts meet these criteria. However, position count, operating temperature range, and contact finish thickness must be evaluated against application requirements.

Q: Why is the substitute part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. While inventory may remain available through distributors, future availability cannot be assured. New designs should prioritize the active TSW-110-14-S-S to ensure long-term supply chain stability.

Q: Are there thermal performance differences between these parts?

A: Yes. The main part operates from -55°C to 125°C, while the substitute operates from -65°C to 105°C. Applications requiring operation above 105°C must use the TSW-110-14-S-S. The substitute provides lower temperature capability but does not match the upper temperature specification.

Q: What is the significance of the contact finish thickness difference?

A: The main part features 30.0µin (0.76µm) gold plating on mating contacts, while the substitute provides 15.0µin (0.38µm). Thicker plating generally provides longer contact life in high-cycle mating applications. For low-cycle or static applications, both thicknesses are typically acceptable.

Q: Can individual positions be broken away from the 40-position substitute?

A: The substitute part is specified as "Header, Breakaway," indicating the design supports position separation. However, breakaway procedures must follow manufacturer guidelines to ensure proper insulation integrity and contact retention. Consult the TE Connectivity AMPMODU Mod II series documentation for specific breakaway procedures.
