TSW-108-14-S-D Equivalent & Substitute Parts

Part Overview

The TSW-108-14-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This vertical header features 16 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. The connector is currently in active product status with full inventory availability.

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

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-108-14-S-D is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for PCB footprint compatibility
• Number of Rows: 2 — determines physical layout and spacing
• Contact Type: Male Pin — defines mating interface
• Mounting Type: Through Hole — establishes board assembly method
• Termination: Solder — specifies connection method
• Row Spacing - Mating: 0.100" (2.54mm) — critical for mechanical fit

The substitute part 4-102973-0 (TE Connectivity AMP Connectors) shares the same mating pitch, row configuration, contact type, mounting method, and termination type. However, this part differs in position count (80 vs. 16), which affects its application scope and physical dimensions. The substitute is listed as obsolete, indicating it is no longer in active production.

Parameter Comparison

Engineering Selection Recommendations

The TSW-108-14-S-D remains the preferred selection for new designs due to its active product status and ROHS3 compliance. This part is currently in stock with full inventory availability.

The substitute part 4-102973-0 is classified as obsolete and RoHS non-compliant, making it unsuitable for applications requiring regulatory compliance with current environmental standards. The higher position count (80 vs. 16) and breakaway feature indicate a different application profile. The reduced operating temperature maximum (-65°C to 105°C vs. -55°C to 125°C) and lower gold plating thickness (15.0µin vs. 30.0µin) represent additional performance differences.

For applications where the TSW-108-14-S-D becomes unavailable, alternative sources should be evaluated based on the critical parameters listed in the substitution criteria section rather than relying on the obsolete 4-102973-0 part.

Frequently Asked Questions (FAQ)

Q: Can the 4-102973-0 be used as a direct replacement for the TSW-108-14-S-D?

A: No. While both parts share the same mating pitch (0.100"), row spacing, and contact type, the 4-102973-0 has 80 positions compared to 16 positions in the TSW-108-14-S-D. This difference affects PCB footprint, physical dimensions, and overall connector length. Additionally, the substitute is obsolete and RoHS non-compliant.

Q: What are the critical parameters for finding a true substitute?

A: The mating pitch (0.100"), number of rows (2), row spacing (0.100"), contact type (male pin), mounting type (through hole), and termination method (solder) must match exactly. Position count compatibility depends on specific application requirements.

Q: Does the difference in operating temperature range affect compatibility?

A: The TSW-108-14-S-D operates from -55°C to 125°C, while the 4-102973-0 operates from -65°C to 105°C. Applications requiring the full temperature range of the primary part cannot use the substitute without thermal performance verification.

Q: What is the significance of RoHS compliance status?

A: The TSW-108-14-S-D is ROHS3 compliant, meeting current environmental regulations for restricted substances. The 4-102973-0 is RoHS non-compliant, which may restrict its use in applications subject to regulatory requirements or customer specifications mandating RoHS compliance.

Q: How does the gold plating thickness difference impact performance?

A: The TSW-108-14-S-D has 30.0µin (0.76µm) gold plating on mating contacts, while the 4-102973-0 has 15.0µin (0.38µm). Thicker plating generally provides enhanced corrosion resistance and contact durability over extended operational life.
