TSW-132-14-L-S Equivalent & Substitute Parts

Part Overview

The TSW-132-14-L-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This connector features 32 positions with 0.100" (2.54mm) pitch spacing, unshrouded design, and solder termination. The part maintains active product status with full inventory availability.

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

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-132-14-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 contact configuration
Mounting Type: Through Hole solder termination
Number of Rows: Single row configuration
Contact Shape: Square pin geometry
Fastening Type: Push-Pull mechanism

The substitute part 4-103321-0 (TE Connectivity AMP Connectors) shares the same mating pitch, connector type, mounting method, and contact configuration. However, this part features 40 positions instead of 32, representing a higher-density variant within the same connector family. Substitution is permissible only when the application design accommodates the increased position count and the connector footprint can be adapted accordingly.

Engineering Selection Recommendations

The TSW-132-14-L-S maintains active product status with ROHS3 compliance and established supply availability. This part is the preferred selection for new designs and ongoing production.

The substitute part 4-103321-0 carries obsolete product status and lacks RoHS compliance documentation. While this connector shares fundamental mechanical and electrical compatibility parameters (pitch, contact type, mounting method), its obsolete classification and non-compliant status make it unsuitable for new applications or long-term production commitments. The 40-position configuration also introduces design modification requirements that are not present with the primary part.

Selection of the TSW-132-14-L-S is recommended for all applications requiring active product support, regulatory compliance assurance, and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 4-103321-0 be used as a direct replacement for the TSW-132-14-L-S?

A: No. While both connectors share the same 0.100" (2.54mm) mating pitch and through-hole solder termination, the 4-103321-0 features 40 positions compared to the 32-position configuration of the TSW-132-14-L-S. Direct substitution requires PCB footprint redesign and connector layout modification. Additionally, the substitute part carries obsolete product status.

Q: What are the critical parameters that determine connector substitutability?

A: Substitution eligibility is determined by: mating pitch (0.100" / 2.54mm), connector type (header with male pins), mounting method (through-hole solder), number of rows (single row), contact shape (square), and fastening mechanism (push-pull). Deviation in any of these parameters requires design validation.

Q: Does the operating temperature range difference affect substitution?

A: The TSW-132-14-L-S operates from -55°C to 125°C, while the 4-103321-0 operates from -65°C to 105°C. The substitute part has a lower maximum temperature rating. Applications requiring operation above 105°C cannot use the substitute part.

Q: What is the significance of the RoHS compliance difference?

A: The TSW-132-14-L-S is ROHS3 compliant, meeting current regulatory requirements for restricted substances. The 4-103321-0 carries "Not applicable" RoHS status, indicating it does not meet modern compliance standards. New designs and regulated applications must use ROHS3-compliant components.

Q: Are the contact finish specifications compatible?

A: The TSW-132-14-L-S features gold-plated mating contacts with phosphor bronze material. The 4-103321-0 uses tin-lead finish with copper alloy material. These differences may affect contact resistance, corrosion resistance, and long-term reliability in specific environmental conditions.
