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

Part Overview

The TSW-117-14-L-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 17-position, single-row header operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts. The connector is currently in active product status and complies with RoHS3 and REACH requirements.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements allow for alternative configurations that maintain functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

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

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for PCB footprint compatibility
• Connector Type: Header with male pin contacts
• Mounting Type: Through Hole
• Termination: Solder
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0 or equivalent
• RoHS Status: ROHS3 Compliant

The substitute part 4-103321-8 (TE Connectivity AMP Connectors) shares the same mating pitch, connector type, mounting method, and termination approach. However, this part is a 40-position header, which represents a different position count than the original 17-position configuration. Substitution is valid only when the application design permits the use of a higher-position-count header or when individual positions can be left unloaded.

Parameter Comparison

Engineering Selection Recommendations

Selection between the TSW-117-14-L-S and 4-103321-8 must account for the following factors:

The TSW-117-14-L-S maintains active product status, ensuring continued availability and manufacturer support. The 4-103321-8 is classified as obsolete, which limits future procurement options and may affect long-term supply chain reliability.

The TSW-117-14-L-S operates across a wider temperature range (-55°C to 125°C) compared to the substitute (-65°C to 105°C). Applications requiring operation above 105°C are incompatible with the substitute part.

Contact finish differences exist: the primary part features gold-plated mating contacts, while the substitute uses tin plating. This affects contact resistance characteristics and corrosion resistance in specific environmental conditions.

The substitute part includes a breakaway feature and accommodates 40 positions versus the original 17 positions. Use of the substitute requires either a PCB redesign to accommodate the additional positions or acceptance of unused contact positions in the connector footprint.

Both parts meet RoHS3 compliance and UL94 V-0 flammability requirements, ensuring regulatory alignment for most applications.

Frequently Asked Questions (FAQ)

Q: Can the 4-103321-8 be used as a direct replacement for the TSW-117-14-L-S?

A: Direct replacement is not possible without design modification. The substitute part has 40 positions instead of 17, requiring either PCB layout changes or acceptance of unused positions. Additionally, the substitute is obsolete, limiting future availability.

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

A: The critical parameters are mating pitch (0.100" / 2.54mm), connector type (header with male pins), mounting method (through-hole), and termination (solder). Both parts meet these criteria, but position count and temperature range differ.

Q: Does the difference in contact finish affect electrical performance?

A: Contact finish differences (gold versus tin) influence contact resistance and environmental corrosion resistance. Gold plating provides superior corrosion resistance in harsh environments, while tin plating is suitable for standard industrial applications. Selection depends on specific environmental exposure requirements.

Q: Why is the substitute part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. This affects procurement availability and may result in higher costs or longer lead times if inventory becomes depleted.

Q: Are there temperature limitations when using the substitute?

A: Yes. The substitute operates to a maximum of 105°C, while the primary part operates to 125°C. Applications requiring sustained operation above 105°C are incompatible with the substitute.

Q: Do both parts comply with RoHS and REACH requirements?

A: Both parts are ROHS3 compliant. The primary part is REACH unaffected, while the substitute has undefined REACH status. Verify REACH compliance with the manufacturer for applications in regulated markets.
