TSW-140-14-F-D Equivalent & Substitute Parts

Part Overview

The TSW-140-14-F-D is a Classic PCB Header Strip manufactured by Samtec Inc., classified as a rectangular connector for through-hole mounting applications. This 80-position, 2-row header connector operates at 0.100" (2.54mm) pitch and is designed for board-to-board or cable interconnection. The part maintains Active product status with 1029 units in current inventory stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when design requirements permit alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-140-14-F-D is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

• Connector Type: Header (with or without breakaway feature)
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 80
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Style: Board to Board or Cable
• Shrouding: Unshrouded

Secondary Compliance Criteria:

• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Product Status: Active

The substitute part 9-146250-0 (TE Connectivity AMP Connectors) satisfies all primary matching criteria and maintains equivalent compliance certifications. Variations in insulation material (LCP vs. PBT), contact finish composition, and operating temperature range do not preclude substitution when the application environment and electrical requirements remain within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (TSW-140-14-F-D): Select the TSW-140-14-F-D when the application requires gold-plated mating contacts and the full operating temperature range of -55°C to 125°C. This part is Active status with established supply availability (1029 units in stock). The PBT insulation material provides proven performance in standard industrial environments.

Substitute Part Selection (9-146250-0): The 9-146250-0 serves as a functional equivalent when:

• The application environment operates within the overlapping temperature range (-55°C to 105°C)
• Tin-plated mating contacts are acceptable for the circuit design
• LCP insulation material meets environmental and mechanical requirements
• The breakaway feature provides design flexibility for modular configurations

Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory equivalence. The 9-146250-0 offers higher current rating specification (3A) and greater inventory availability (2383 units in stock).

Mechanical Compatibility: Contact length variations (mating: ±0.05mm, post: ±0.39mm, overall: ±0.09mm) and insulation height difference (0.010") fall within standard manufacturing tolerances for 0.100" pitch connectors and do not affect mating performance or PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 9-146250-0 be used as a direct replacement for the TSW-140-14-F-D in all applications?

A: The 9-146250-0 is mechanically and electrically compatible for applications operating within the overlapping temperature range (-55°C to 105°C). If your application requires operation above 105°C, the TSW-140-14-F-D is required. Verify that tin-plated contacts are acceptable for your circuit design, as the TSW-140-14-F-D uses gold plating.

Q: What is the difference between the contact finishes?

A: The TSW-140-14-F-D features gold-plated mating contacts (3.00µin thickness), providing superior corrosion resistance and lower contact resistance. The 9-146250-0 uses tin-plated mating contacts (100.0µin thickness), which is suitable for standard industrial applications but may require verification for high-reliability or corrosive environments.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: Yes. Both connectors maintain identical pitch (0.100"), row spacing (0.100"), position count (80), and row configuration (2 rows). Contact length variations are within standard manufacturing tolerances and do not affect PCB footprint or mating performance.

Q: What is the significance of the breakaway feature on the 9-146250-0?

A: The breakaway feature on the AMPMODU Mod II series allows individual connector sections to be separated for modular applications. This feature does not affect compatibility with standard 80-position header applications and provides additional design flexibility if required.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the TSW-140-14-F-D and 9-146250-0 are ROHS3 compliant and carry UL94 V-0 flammability certification. Both are classified as Active products with established manufacturing support.

Q: Which part should be selected for new designs?

A: For new designs, either part is acceptable based on application requirements. If the design operates below 105°C and tin-plated contacts are acceptable, the 9-146250-0 offers higher current rating (3A) and greater inventory availability. If the design requires the full -55°C to 125°C temperature range or gold-plated contacts, select the TSW-140-14-F-D.
