TSW-136-14-F-D Equivalent & Substitute Parts

Part Overview

The TSW-136-14-F-D is a classic PCB header strip manufactured by Samtec Inc., designed for through-hole board-to-board or cable connections. This unshrouded, two-row connector features 72 positions at 0.100" (2.54mm) pitch with gold-plated mating contacts and tin-plated posts. The component maintains Active product status with 859 units in current inventory stock.

Substitute parts are identified when equivalent electrical and mechanical parameters align within the allowed specifications for rectangular connector headers. Substitution becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or alternative sourcing is required while maintaining functional compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-136-14-F-D is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector Type: Header (with or without breakaway feature)
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Shrouding: Unshrouded
• Style: Board to Board or Cable
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Allowable Variations:

• Number of Positions: Substitute parts may exceed the original 72-position count, provided the connector maintains mechanical and electrical compatibility within the same pitch and row configuration
• Insulation Material: Alternative materials (such as Liquid Crystal Polymer) are acceptable if they maintain equivalent electrical and thermal performance
• Contact Finish: Variations in mating contact finish (gold vs. tin) and finish thickness are permitted based on application requirements
• Operating Temperature Range: Substitute parts with extended or equivalent temperature ranges are acceptable
• Contact Length: Minor variations in mating contact length, post length, and overall contact length are acceptable within standard manufacturing tolerances

The substitute part 9-146250-0 meets all primary substitution criteria and operates within allowable parameter variations.

Engineering Selection Recommendations

Primary Part Selection (TSW-136-14-F-D): The TSW-136-14-F-D maintains Active product status with established inventory availability. This part is suitable for applications requiring exactly 72 positions with gold-plated mating contacts and extended temperature operation to 125°C. The component meets ROHS3 compliance and UL94 V-0 flammability requirements for regulated applications.

Substitute Part Selection (9-146250-0): The 9-146250-0 from TE Connectivity AMP Connectors is a qualified substitute when the following conditions are met:

1. Position Count Compatibility: The application design accommodates 80 positions instead of 72. The additional 8 positions do not create mechanical or electrical conflicts on the PCB layout.

2. Temperature Range Compatibility: The application operating temperature does not exceed 105°C. If sustained operation above 105°C is required, the primary part TSW-136-14-F-D is necessary.

3. Contact Finish Acceptance: The application accepts tin-plated mating contacts in place of gold plating. Tin plating is suitable for standard signal and power distribution applications without corrosive environmental exposure.

4. Insulation Material Compatibility: The application accepts Liquid Crystal Polymer (LCP) insulation material in place of PBT. Both materials meet identical flammability and regulatory requirements.

5. Regulatory Compliance: Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, suitable for regulated markets and safety-critical applications.

Inventory and Sourcing: The substitute part 9-146250-0 maintains higher inventory availability (2383 units) compared to the primary part (859 units), providing supply chain flexibility for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 9-146250-0 substitute directly for the TSW-136-14-F-D in a 72-position application?

A: The 9-146250-0 is an 80-position connector. Direct substitution requires PCB layout modification to accommodate the additional 8 positions. If the PCB design is fixed at 72 positions, only the first 72 positions of the substitute part would be populated, leaving 8 positions unused. This configuration is mechanically and electrically valid but represents inefficient component utilization.

Q: What is the impact of the different contact finishes (gold vs. tin)?

A: Gold plating on the TSW-136-14-F-D provides superior corrosion resistance and is preferred for high-reliability applications, aerospace, and environments with potential corrosive exposure. Tin plating on the 9-146250-0 is suitable for standard industrial and commercial applications with controlled environmental conditions. Both finishes provide adequate electrical conductivity for signal and power distribution. Contact finish selection depends on application environment and reliability requirements.

Q: Are there temperature limitations when substituting the 9-146250-0?

A: The 9-146250-0 operates to a maximum of 105°C, compared to 125°C for the TSW-136-14-F-D. Applications requiring sustained operation above 105°C must use the primary part. Applications with maximum operating temperatures at or below 105°C are fully compatible with the substitute part.

Q: What is the significance of the different insulation materials (PBT vs. LCP)?

A: Both Polybutylene Terephthalate (PBT) and Liquid Crystal Polymer (LCP) meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and lower moisture absorption compared to PBT. For applications requiring tight mechanical tolerances or high-humidity environments, LCP provides performance advantages. For standard applications, both materials are functionally equivalent.

Q: Does the substitute part's breakaway feature affect compatibility?

A: The breakaway feature on the 9-146250-0 allows individual connector sections to be separated after assembly. This feature does not affect compatibility with the mating connector or PCB interface. The breakaway capability adds design flexibility for applications requiring modular connector configurations.

Q: What are the implications of the different post lengths (0.110" vs. 0.125")?

A: The substitute part's longer post (0.125" vs. 0.110") accommodates standard PCB through-hole spacing without compatibility issues. The longer post provides additional solder joint length, potentially improving mechanical robustness. PCB design with standard 0.100" (2.54mm) pitch spacing is compatible with both post lengths.

Q: Are both parts suitable for high-volume production?

A: Both parts are suitable for high-volume production. The substitute part 9-146250-0 offers higher inventory availability (2383 units vs. 859 units), providing supply chain advantages for large production runs. Both parts maintain Active product status and ROHS3 compliance for regulated manufacturing environments.

Q: What is the MSL (Moisture Sensitivity Level) rating, and why does it matter?

A: The 9-146250-0 carries an MSL 1 rating, indicating unlimited shelf life without moisture-related degradation. The TSW-136-14-F-D does not specify an MSL rating. MSL 1 is the most favorable rating for long-term storage and supply chain flexibility, particularly for applications with extended lead times or inventory holding periods.
