TSW-132-07-S-D Equivalent & Substitute Parts

Part Overview

The TSW-132-07-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 64-position, 2-row connector operates across a wide temperature range (-55°C to 125°C) and features gold-plated mating contacts with tin-plated posts. The part maintains Active product status and full RoHS3 compliance. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 8-146256-2 (TE Connectivity AMP Connectors) qualifies as an equivalent based on the following critical parameters:

Matching Parameters:

• Connector Type: Header with breakaway capability
• Contact Type: Male Pin
• Number of Positions: 64
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Insulation Color: Black
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)
• HTSUS Code: 8536.69.4040

The substitute part maintains functional and mechanical compatibility through identical mating pitch, position count, row configuration, and termination method. Both parts support board-to-board or cable applications with equivalent electrical interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-132-07-S-D and 8-146256-2 maintain Active product status and full compliance with applicable regulatory standards. Selection between these parts depends on specific application requirements:

TSW-132-07-S-D (Samtec Inc.) is suitable when:

• Maximum operating temperature of 125°C is required
• Thicker gold plating (30.0µin) is specified for enhanced contact durability
• PBT insulation material is preferred for the application
• Phosphor Bronze contact material is required

8-146256-2 (TE Connectivity AMP Connectors) is suitable when:

• Extended low-temperature operation to -65°C is required
• Breakaway connector capability provides design flexibility
• LCP insulation material meets application specifications
• Copper Alloy contact material is acceptable
• 3A current rating specification is required

Both parts satisfy RoHS compliance requirements and MSL Level 1 handling. Mechanical compatibility is maintained across the 64-position, 2.54mm pitch configuration. Minor dimensional variations in contact post length and insulation height do not affect standard through-hole PCB mounting practices.

Frequently Asked Questions (FAQ)

Q: Can 8-146256-2 be used as a direct replacement for TSW-132-07-S-D in all applications?

A: The 8-146256-2 is mechanically and electrically compatible for standard board-to-board applications. However, verify that your application does not require the higher maximum operating temperature (125°C) of the Samtec part or the specific contact finish thickness of the original design. The TE part's breakaway feature is an additive capability that does not affect compatibility.

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

A: Both materials are UL94 V-0 rated and suitable for connector applications. PBT (Polybutylene Terephthalate) offers good mechanical properties and cost efficiency. LCP (Liquid Crystal Polymer) provides superior dimensional stability and lower moisture absorption. Selection depends on environmental exposure and mechanical stress requirements in your specific application.

Q: Why does the TE part have a longer contact post (0.120" vs. 0.100")?

A: The longer post on the 8-146256-2 accommodates different PCB thickness tolerances and solder joint formation requirements. For standard PCB applications with typical thickness (0.062"), this difference does not affect functionality. Verify compatibility with your specific PCB thickness and solder process parameters.

Q: Are there temperature range differences I should consider?

A: The Samtec TSW-132-07-S-D operates from -55°C to 125°C, while the TE 8-146256-2 operates from -65°C to 105°C. If your application requires sustained operation above 105°C, the Samtec part is required. If operation below -55°C is needed, the TE part provides extended low-temperature capability.

Q: What is the difference in gold plating thickness, and does it matter?

A: The Samtec part specifies 30.0µin (0.76µm) gold plating versus 15.0µin (0.38µm) on the TE part. Thicker plating provides enhanced contact durability and corrosion resistance in high-cycle mating applications. For applications with limited mating cycles or benign environments, both thicknesses are acceptable.

Q: Are both parts RoHS compliant?

A: Yes. The Samtec TSW-132-07-S-D is ROHS3 Compliant, and the TE 8-146256-2 is RoHS Compliant. Both meet the requirements for lead-free and restricted substance compliance in regulated markets.

Q: Can I mix these connectors in the same assembly?

A: These connectors are designed for mating with compatible receptacle connectors. Verify that your mating receptacle is compatible with both the 2.54mm pitch and the specific contact geometry of whichever connector you select. Do not mix different connector types in the same mating interface.
