TSW-117-14-S-S Equivalent & Substitute Parts

Part Overview

The TSW-117-14-S-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 17-position, single-row connector operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts. The part maintains active product status with full inventory availability. Substitute parts are identified when equivalent electrical and mechanical parameters align within the allowed specifications for this connector category, enabling direct functional replacement in board-to-board or cable applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-117-14-S-S is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical compatibility
• Contact Type: Male Pin — determines mating interface
• Mounting Type: Through Hole — establishes PCB assembly method
• Termination: Solder — defines connection method
• Contact Finish - Mating: Gold — ensures electrical performance and corrosion resistance
• Insulation Material: PBT or equivalent thermoplastic — provides structural integrity
• Operating Temperature Range: Must encompass or exceed -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0 — meets safety requirements
• RoHS Compliance: ROHS3 Compliant — ensures regulatory alignment

The identified substitute part 4-102976-0 (TE Connectivity AMP Connectors) shares the core electrical and mechanical parameters required for functional equivalence within rectangular connector applications. However, specific differences in position count, contact dimensions, and product status must be evaluated for application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

The TSW-117-14-S-S maintains active product status with ROHS3 compliance, making it the preferred selection for new designs and applications requiring current regulatory alignment. The part is in full inventory stock with established supply continuity.

The substitute part 4-102976-0 carries obsolete product status and does not maintain RoHS compliance documentation. While it shares core electrical and mechanical parameters including pitch, contact type, mounting method, and flammability rating, its obsolescence status and lack of RoHS compliance present supply and regulatory risks for production applications.

Selection between these parts must account for:

• Position Count Difference: The main part provides 17 positions; the substitute provides 40 positions. Application-specific connector requirements determine compatibility.
• Operating Temperature Range: The main part operates -55°C ~ 125°C; the substitute operates -65°C ~ 105°C. Applications requiring the full upper temperature range of 125°C require the main part.
• Contact Post Finish: The main part uses tin finish; the substitute uses tin-lead finish. Lead-free requirements mandate the main part.
• Regulatory Compliance: ROHS3 compliance is confirmed for the main part only.
• Product Lifecycle: Active status ensures long-term availability for the main part; obsolete status for the substitute indicates limited future supply.

Frequently Asked Questions (FAQ)

Q: Can the 4-102976-0 substitute directly replace the TSW-117-14-S-S in all applications?

A: Direct replacement is not universal. The substitute has 40 positions versus 17 positions in the main part. Applications using only 17 positions can accommodate the substitute mechanically, but the additional 23 positions remain unused. The substitute's obsolete status and lack of RoHS compliance create regulatory and supply chain risks.

Q: What is the significance of the pitch specification in connector substitution?

A: Pitch (0.100" / 2.54mm) defines the center-to-center spacing between adjacent contacts. Both parts share identical pitch, ensuring mechanical compatibility with mating connectors and PCB layouts designed for this spacing. Pitch mismatch prevents proper mating and causes electrical failure.

Q: How do contact finish specifications affect substitution?

A: The main part uses gold-plated mating contacts with tin-plated posts; the substitute uses gold-plated mating contacts with tin-lead posts. Gold plating ensures corrosion resistance and reliable electrical contact. The tin-lead finish on the substitute's posts conflicts with lead-free manufacturing requirements (RoHS3), making it unsuitable for applications requiring lead-free compliance.

Q: Why is product status relevant to component selection?

A: Active product status indicates ongoing manufacturing, quality assurance, and supply availability. Obsolete products face discontinuation risk, limited inventory, and potential quality control gaps. For production applications, active-status components provide supply chain stability and regulatory support.

Q: Does the operating temperature range difference affect substitution decisions?

A: The main part operates -55°C ~ 125°C; the substitute operates -65°C ~ 105°C. Applications requiring operation at 125°C cannot use the substitute. The main part's extended upper temperature range provides broader application coverage.

Q: What role does insulation material play in connector equivalence?

A: Both parts use thermoplastic insulation materials (PBT for the main part, unspecified thermoplastic for the substitute). These materials provide structural integrity, electrical isolation, and flame resistance (UL94 V-0). Material equivalence ensures mechanical durability and safety compliance across thermal cycles and environmental exposure.
