TSW-113-14-L-S Equivalent & Substitute Parts

Part Overview

The TSW-113-14-L-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 13-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 become necessary when the primary component reaches end-of-life, experiences supply constraints, or when design requirements permit alternative configurations that meet the same electrical and mechanical interface standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-113-14-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
• Number of Rows: Single row configuration
• Contact Finish: Gold mating surface for signal integrity

The substitute part 4-103321-0 (TE Connectivity AMP Connectors AMPMODU Mod II series) shares the same 0.100" (2.54mm) pitch, through-hole solder termination, and single-row header configuration. However, this part is rated for 40 positions, which exceeds the 13-position requirement of the main part. This substitute is applicable only in applications where the additional positions can be accommodated or remain unused on the PCB.

Parameter Comparison

Engineering Selection Recommendations

The TSW-113-14-L-S remains the preferred choice for new designs due to its active product status, ROHS3 compliance, and extended operating temperature range (-55°C to 125°C).

The substitute part 4-103321-0 carries obsolete product status, which indicates discontinued manufacturing and limited future availability. Additionally, this substitute features tin-lead contact finish rather than gold, and operates within a narrower temperature range (-65°C to 105°C). The 40-position configuration introduces mechanical and electrical considerations that differ from the 13-position main part.

Selection of the substitute should be limited to legacy system maintenance or applications where the additional positions and tin-lead finish are functionally acceptable within the design constraints.

Frequently Asked Questions (FAQ)

Q: Can the 4-103321-0 substitute be used directly in place of the TSW-113-14-L-S?

A: Direct substitution is not recommended without design review. While both connectors share the same 0.100" (2.54mm) pitch and through-hole solder termination, the substitute features 40 positions versus 13 positions in the main part. PCB footprint compatibility must be verified before implementation.

Q: What are the key differences in contact finish between these parts?

A: The TSW-113-14-L-S uses gold-plated mating contacts (10.0µin thickness) with tin-plated posts. The 4-103321-0 uses tin-lead finish on both mating and post surfaces. Gold plating provides superior corrosion resistance and signal integrity in high-reliability applications.

Q: Are there temperature rating implications for substitution?

A: 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 cannot use the substitute. The main part provides a 20°C advantage at the upper temperature limit.

Q: What is the significance of the obsolete product status for the substitute?

A: Obsolete status indicates the substitute is no longer manufactured. Existing inventory may be available, but future procurement cannot be guaranteed. New designs should not rely on obsolete components.

Q: Does the breakaway feature of the substitute affect compatibility?

A: The breakaway feature allows individual positions to be separated from the connector body. This does not affect electrical or mechanical compatibility with standard 0.100" (2.54mm) pitch receptacles, but it introduces design considerations for mechanical retention and positioning.
