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

Part Overview

The TSW-115-14-F-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 30-position, 2-row connector operates across a wide temperature range of -55°C to 125°C and features gold-plated mating contacts with tin-plated posts. The part maintains Active product status with full RoHS3 compliance and MSL Level 1 rating, making it suitable for industrial and commercial applications requiring reliable interconnection.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits accommodation of alternative connector architectures that maintain functional compatibility within the application's electrical and mechanical requirements.

Key Parameters

Substitute Part Grouping Explanation

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

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical and electrical compatibility
• Contact Type: Male Pin — determines mating interface requirements
• Mounting Type: Through Hole — establishes PCB assembly process compatibility
• Termination: Solder — defines post-processing and rework procedures
• Number of Rows: 2 — establishes physical footprint and spacing requirements
• Contact Shape: Square — ensures proper contact engagement and current distribution

The substitute part 4-103322-2 (TE Connectivity AMP Connectors) shares the core electrical and mechanical parameters necessary for functional substitution. However, critical differences exist in position count, temperature range, and product status that must be evaluated within specific application contexts.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (TSW-115-14-F-D): Recommended for new designs and applications requiring extended production lifecycles. Active product status ensures long-term availability and supply chain stability. Superior operating temperature range (-55°C to 125°C) accommodates demanding thermal environments. Gold-plated mating contacts provide enhanced corrosion resistance in harsh or high-humidity applications. ROHS3 compliance meets current regulatory requirements.

Substitute Part (4-103322-2): Acceptable only for legacy system maintenance or applications with specific inventory constraints. Obsolete product status indicates discontinued manufacturing, limiting future availability. Operating temperature range (-65°C to 105°C) is narrower at the upper limit, unsuitable for high-temperature applications. Higher position count (80 vs. 30) requires PCB redesign and is not a direct drop-in replacement. Tin-plated contacts offer reduced corrosion resistance compared to gold plating. RoHS compliance is confirmed but does not meet ROHS3 standard.

Substitution is not recommended for new production designs. Use only when primary part availability is exhausted and application thermal and environmental requirements fall within the substitute's operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 4-103322-2 be used as a direct replacement for the TSW-115-14-F-D?

A: No. While both connectors share identical pitch (2.54mm), row count, and mounting type, the 4-103322-2 has 80 positions versus 30 positions in the TSW-115-14-F-D. This requires PCB layout modification and is not a direct drop-in replacement. Additionally, the substitute is obsolete and no longer manufactured.

Q: What are the critical compatibility parameters for substitution?

A: Mating pitch (0.100" / 2.54mm), contact type (Male Pin), number of rows (2), row spacing (0.100" / 2.54mm), mounting type (Through Hole), termination (Solder), and contact shape (Square) must remain constant. Deviations in these parameters prevent functional compatibility.

Q: How do the contact finishes differ, and does this affect performance?

A: The TSW-115-14-F-D uses gold plating (3.00µin thickness) on mating contacts, providing superior corrosion resistance and lower contact resistance. The 4-103322-2 uses tin plating (100.0µin thickness), which is more susceptible to corrosion in humid or corrosive environments. Gold plating is preferred for high-reliability applications.

Q: What is the significance of the operating temperature range difference?

A: The TSW-115-14-F-D operates from -55°C to 125°C, while the 4-103322-2 operates from -65°C to 105°C. The main part supports higher-temperature applications (up to 125°C), making it suitable for automotive, industrial, and aerospace environments. The substitute cannot be used in applications exceeding 105°C.

Q: Why is product status important in component selection?

A: Active product status (TSW-115-14-F-D) ensures ongoing manufacturing, consistent supply availability, and manufacturer support. Obsolete status (4-103322-2) indicates discontinued production, creating supply uncertainty and potential quality variability in remaining inventory. New designs must use active products to ensure long-term viability.

Q: Are there differences in insulation height that affect PCB design?

A: Yes. The TSW-115-14-F-D has 0.100" (2.54mm) insulation height, while the 4-103322-2 has 0.090" (2.29mm). This 0.25mm difference may affect clearance calculations for adjacent components or routing constraints on the PCB. Verify clearance requirements before substitution.

Q: Do both connectors meet current regulatory compliance standards?

A: The TSW-115-14-F-D meets ROHS3 compliance, representing the latest regulatory standard. The 4-103322-2 meets RoHS compliance but does not meet ROHS3. For applications subject to current environmental regulations, the main part is required.
