TSW-115-14-L-S Equivalent & Substitute Parts

Part Overview

The TSW-115-14-L-S is an active rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 15-position, single-row header operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts. The connector is suitable for board-to-board or cable interconnection in applications requiring push-pull fastening and unshrouded design. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or design flexibility needs while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSW-115-14-L-S is evaluated based on the following critical parameters that must align for functional compatibility:

• Pitch - Mating: 0.100" (2.54mm) — determines PCB footprint compatibility
• Connector Type: Header with male pin contacts — ensures mating interface compatibility
• Mounting Type: Through Hole — required for PCB assembly method
• Termination: Solder — specifies connection method to PCB
• Fastening Type: Push-Pull — defines mechanical engagement mechanism
• Number of Rows: 1 — establishes physical form factor
• Shrouding: Unshrouded — defines connector profile and accessibility

The substitute part 9-146274-0 (TE Connectivity AMP Connectors) differs in position count (40 vs. 15), which makes it suitable only for applications where the higher position count is acceptable or where individual positions can be utilized selectively. Both parts share identical pitch, connector type, mounting method, termination, fastening mechanism, and row configuration, establishing the basis for substitution consideration.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-115-14-L-S and 9-146274-0 maintain active product status and comply with RoHS and REACH regulations. The primary distinction lies in position count: the TSW-115-14-L-S provides 15 positions, while the 9-146274-0 provides 40 positions with breakaway capability.

Selection between these parts depends on application requirements. The TSW-115-14-L-S is appropriate for designs requiring exactly 15 positions with gold-plated mating contacts and a phosphor bronze contact material operating across -55°C to 125°C. The 9-146274-0 accommodates higher position counts with tin-plated mating contacts and copper alloy material, operating across -65°C to 105°C, with a specified 3A current rating and breakaway feature.

Both parts share identical pitch, connector type, mounting method, termination, fastening mechanism, and row configuration. Differences in contact finish, contact material, insulation material, operating temperature range, and position count must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 9-146274-0 directly replace the TSW-115-14-L-S in existing designs?

A: Direct replacement is not recommended without design review. While both connectors share 0.100" (2.54mm) pitch, identical connector type, mounting method, and fastening mechanism, the 9-146274-0 provides 40 positions versus 15 positions in the TSW-115-14-L-S. PCB footprint compatibility must be verified. Additionally, contact finish differs (tin vs. gold), and operating temperature ranges differ (-65°C to 105°C vs. -55°C to 125°C).

Q: What are the key compatibility factors between these two connectors?

A: Compatibility is established through: 0.100" (2.54mm) mating pitch, single-row unshrouded header configuration, through-hole solder termination, push-pull fastening mechanism, and male pin contact type. These parameters ensure mechanical and electrical interface compatibility at the mating surface.

Q: How do the contact finishes differ between these parts?

A: The TSW-115-14-L-S features gold-plated mating contacts (10.0µin thickness) with tin-plated posts. The 9-146274-0 features tin-plated mating contacts (100.0µin thickness) with tin-plated posts. Gold plating provides enhanced corrosion resistance and lower contact resistance, while tin plating offers cost efficiency and adequate performance in standard environments.

Q: What is the significance of the breakaway feature on the 9-146274-0?

A: The breakaway feature on the 9-146274-0 allows individual positions to be separated from the main connector body, providing design flexibility for applications requiring variable position counts. The TSW-115-14-L-S does not include this feature.

Q: Are there temperature range considerations for substitution?

A: Yes. The TSW-115-14-L-S operates from -55°C to 125°C, while the 9-146274-0 operates from -65°C to 105°C. Applications requiring operation above 105°C must use the TSW-115-14-L-S. Applications requiring operation below -55°C can use either part, though the 9-146274-0 extends to -65°C.

Q: What insulation materials are used in each connector?

A: The TSW-115-14-L-S uses Polybutylene Terephthalate (PBT), while the 9-146274-0 uses Liquid Crystal Polymer (LCP). Both materials are UL94 V-0 rated. LCP offers superior dimensional stability and lower moisture absorption, while PBT provides established reliability in standard applications.
