TSW-130-14-L-S Equivalent & Substitute Parts

Part Overview

The TSW-130-14-L-S is an active rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 30-position, single-row header operates across an extended temperature range of -55°C to 125°C and meets UL94 V-0 flammability requirements. The part is RoHS3 compliant and carries MSL 1 (unlimited moisture sensitivity level) classification. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit component flexibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-130-14-L-S is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for PCB footprint compatibility
• Contact Type: Male Pin — determines mating interface
• Mounting Type: Through Hole — establishes board assembly method
• Termination: Solder — specifies connection method
• Material Flammability Rating: UL94 V-0 — ensures compliance with safety standards
• RoHS Status: RoHS3 Compliant — meets environmental regulations
• MSL Rating: 1 (Unlimited) — indicates moisture handling requirements

The substitute part 9-146274-0 (TE Connectivity AMP Connectors) shares these critical parameters. However, differences exist in position count (40 vs. 30), operating temperature range (-65°C ~ 105°C vs. -55°C ~ 125°C), insulation material (LCP vs. PBT), and contact finish specifications. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-130-14-L-S and 9-146274-0 maintain active product status and meet UL94 V-0 flammability requirements with MSL 1 (Unlimited) ratings. Both are RoHS compliant and REACH unaffected, satisfying environmental and regulatory compliance requirements.

Selection between these parts must account for the following differences:

Position Count: The TSW-130-14-L-S provides 30 positions, while the 9-146274-0 provides 40 positions. PCB footprint and connector cavity design must accommodate the selected position count.

Operating Temperature Range: The TSW-130-14-L-S operates from -55°C to 125°C, providing extended high-temperature capability. The 9-146274-0 operates from -65°C to 105°C, offering extended low-temperature capability but reduced maximum temperature. Application thermal requirements determine suitability.

Contact Finish: The TSW-130-14-L-S features gold-plated mating contacts, while the 9-146274-0 uses tin plating. Gold plating provides enhanced corrosion resistance and contact reliability in demanding environments.

Insulation Material: The TSW-130-14-L-S uses PBT, while the 9-146274-0 uses LCP. Both materials meet UL94 V-0 requirements; material selection depends on mechanical and thermal performance requirements specific to the application.

Post Length: The 9-146274-0 provides 0.125" (3.18mm) post length compared to 0.110" (2.79mm) for the TSW-130-14-L-S, affecting solder joint geometry and PCB thickness compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 9-146274-0 be used as a direct replacement for the TSW-130-14-L-S?

A: Direct replacement is not possible due to position count difference (40 vs. 30). The 9-146274-0 requires a different PCB footprint and connector cavity design. Substitution is only viable if the application design can accommodate 40 positions and the associated dimensional changes.

Q: What is the significance of the pitch specification in connector selection?

A: Pitch (0.100" or 2.54mm) defines the center-to-center spacing between contact positions. Both parts share identical pitch, ensuring compatibility with standard 0.100" spaced PCB layouts. Pitch mismatch prevents proper mating and creates assembly incompatibility.

Q: How do operating temperature ranges affect part selection?

A: The TSW-130-14-L-S supports higher maximum temperature (125°C vs. 105°C), making it suitable for high-temperature applications. The 9-146274-0 supports lower minimum temperature (-65°C vs. -55°C), making it suitable for extreme cold environments. Application thermal specifications determine which part is appropriate.

Q: What is the difference between gold and tin contact finishes?

A: Gold plating (TSW-130-14-L-S) provides superior corrosion resistance and contact reliability, particularly in harsh or high-reliability applications. Tin plating (9-146274-0) is cost-effective and suitable for standard industrial applications. Contact finish selection depends on environmental exposure and reliability requirements.

Q: Does the breakaway feature of the 9-146274-0 affect compatibility?

A: The breakaway feature allows individual positions to be separated from the connector body. This feature does not affect electrical or mechanical compatibility with mating connectors but provides design flexibility for applications requiring modular connector configurations.

Q: How do insulation material differences impact performance?

A: Both PBT (TSW-130-14-L-S) and LCP (9-146274-0) meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and lower moisture absorption, while PBT provides established performance in standard applications. Material selection depends on specific mechanical and environmental requirements.

Q: What role does MSL rating play in component handling?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These connectors do not require special moisture-controlled storage or baking procedures prior to assembly, simplifying inventory and manufacturing logistics.
