TSW-112-14-L-D Equivalent & Substitute Parts

Part Overview

The TSW-112-14-L-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This connector features 24 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. The part is currently in active production status with gold-plated mating contacts and tin-plated posts, operating across a temperature range of -55°C to 125°C. Substitute parts become necessary when addressing specific application requirements, managing inventory constraints, or accommodating design revisions that permit alternative connector configurations within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-112-14-L-D is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — substitute parts must maintain identical mating pitch to ensure mechanical and electrical compatibility
• Connector Type: Header configuration for board-to-board or cable applications
• Contact Type: Male pin contacts
• Mounting Type: Through-hole termination
• Number of Rows: 2-row configuration
• Row Spacing: 0.100" (2.54mm)
• Termination Method: Solder attachment
• Operating Temperature Range: -55°C ~ 125°C minimum capability
• Material Flammability: UL94 V-0 compliance

The identified substitute part, 4-103322-0 from TE Connectivity AMP Connectors, differs significantly in position count (80 positions versus 24 positions) and several material specifications. This part does not meet the substitution criteria for direct replacement applications requiring the exact 24-position configuration of the TSW-112-14-L-D.

Parameter Comparison

Engineering Selection Recommendations

The 4-103322-0 does not qualify as a direct substitute for the TSW-112-14-L-D based on the provided parameters. Critical incompatibilities include:

• Position Count Disparity: The 80-position configuration of the 4-103322-0 is fundamentally incompatible with applications designed for the 24-position TSW-112-14-L-D, requiring complete PCB redesign and connector footprint modification.
• Product Status: The TSW-112-14-L-D maintains active production status, while the 4-103322-0 is obsolete, limiting availability and long-term supply chain viability.
• RoHS Compliance: The TSW-112-14-L-D is ROHS3 compliant, whereas the 4-103322-0 status is not applicable, creating regulatory compliance concerns for applications subject to RoHS requirements.
• Contact Finish and Material Specifications: Differences in contact finish (gold versus tin-lead), contact material (phosphor bronze versus copper alloy), and insulation material (PBT versus thermoplastic) introduce electrical performance and reliability variations.
• Operating Temperature Range: The TSW-112-14-L-D supports -55°C to 125°C operation, while the 4-103322-0 maximum temperature is limited to 105°C, restricting high-temperature applications.

For applications requiring a 24-position, 2-row, 0.100" pitch header connector with active product status and ROHS3 compliance, the TSW-112-14-L-D remains the specified component. Alternative solutions should be sourced from Samtec's current product portfolio or equivalent manufacturers offering comparable specifications within the same position and pitch parameters.

Frequently Asked Questions (FAQ)

Q: Can the 4-103322-0 be used as a direct replacement for the TSW-112-14-L-D?

A: No. The 4-103322-0 has 80 positions compared to the 24-position configuration of the TSW-112-14-L-D. This fundamental difference requires complete redesign of the connector footprint and PCB layout, making it unsuitable for direct replacement applications.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by mating pitch (0.100"), number of rows (2), row spacing (0.100"), connector type (header), contact type (male pin), mounting type (through-hole), and termination method (solder). Position count is a critical parameter that must match the application requirements.

Q: Why is product status relevant to substitution decisions?

A: The TSW-112-14-L-D is in active production, ensuring ongoing availability and supply chain stability. The 4-103322-0 is obsolete, presenting long-term procurement risks and potential discontinuation of technical support.

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

A: Contact finish differences (gold versus tin-lead) can affect contact resistance, corrosion resistance, and long-term reliability. Gold plating on the TSW-112-14-L-D provides superior corrosion resistance and lower contact resistance compared to tin-lead finishes.

Q: What is the significance of RoHS compliance status?

A: RoHS3 compliance on the TSW-112-14-L-D ensures the connector meets European Union restrictions on hazardous substances. Applications subject to RoHS regulations require compliant components. The 4-103322-0 status is not applicable, creating regulatory compliance gaps.

Q: Are there temperature limitations when selecting a substitute?

A: Yes. The TSW-112-14-L-D operates from -55°C to 125°C. The 4-103322-0 maximum operating temperature is 105°C, making it unsuitable for high-temperature applications exceeding 105°C.
