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

Part Overview

The TSW-115-14-L-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This connector features 30 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, suitable for board-to-board or cable interconnections. The part maintains active product status with 782 units in current inventory. Identifying equivalent and substitute parts becomes necessary when addressing supply chain requirements, design revisions, or application-specific compatibility needs while maintaining electrical and mechanical performance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-115-14-L-D is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical compatibility
• Contact Type: Male Pin — determines mating interface requirements
• Mounting Type: Through Hole — establishes PCB assembly method
• Termination: Solder — specifies connection method to substrate
• Number of Rows: 2 — defines physical layout and spacing
• Connector Type: Header — establishes functional classification

The identified substitute part, 4-103322-0 (TE Connectivity AMP Connectors), shares the core electrical and mechanical parameters necessary for functional equivalence. However, critical differences exist in position count, temperature rating, and product status that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TSW-115-14-L-D maintains active product status with established supply availability. The substitute part 4-103322-0 is classified as obsolete, which presents supply chain risk for new designs or long-term production requirements.

Key compliance considerations:

• The main part (TSW-115-14-L-D) is ROHS3 compliant, while the substitute (4-103322-0) carries "Not applicable" RoHS status, indicating it does not meet current regulatory requirements for restricted substances.
• Both parts achieve UL94 V-0 flammability rating, meeting fire safety standards.
• The main part supports an operating temperature range of -55°C to 125°C, while the substitute operates within -65°C to 105°C. Applications requiring sustained operation above 105°C cannot use the substitute part.

For new designs or applications requiring long-term supply assurance and regulatory compliance, the TSW-115-14-L-D is the appropriate selection. The substitute part may be considered only for legacy system maintenance where supply of the original part is unavailable and application temperature and RoHS requirements do not apply.

Frequently Asked Questions (FAQ)

Q: Can the 4-103322-0 be used as a direct replacement for the TSW-115-14-L-D?

A: No. While both parts share identical pitch spacing (0.100"), row configuration (2 rows), and mounting method (through-hole solder), the substitute has 80 positions compared to 30 positions in the main part. This difference in position count makes direct substitution impossible without circuit redesign. Additionally, the substitute is obsolete and does not meet ROHS3 compliance requirements.

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

A: Substitution compatibility is determined by: pitch spacing (0.100"), contact type (male pin), number of rows (2), mounting type (through-hole), and termination method (solder). Deviations in any of these parameters eliminate substitution viability.

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

A: The main part features gold-plated mating contacts, while the substitute uses tin-lead finish. Both finishes provide adequate electrical conductivity for standard applications. However, gold plating offers superior corrosion resistance and is preferred for high-reliability applications or environments with corrosive exposure.

Q: Are there temperature limitations when considering substitution?

A: Yes. The main part operates from -55°C to 125°C, while the substitute operates from -65°C to 105°C. Applications requiring sustained operation above 105°C cannot use the substitute part. The main part provides 20°C additional high-temperature capability.

Q: What is the significance of the "Obsolete" product status for the substitute part?

A: Obsolete status indicates the part is no longer manufactured or supported by the supplier. This creates supply chain risk, potential unavailability for future orders, and lack of manufacturer technical support. For production applications, active-status parts are strongly preferred.
