TSW-132-14-F-S Equivalent & Substitute Parts

Part Overview

The TSW-132-14-F-S is a classic PCB header strip manufactured by Samtec Inc., designed for through-hole board-to-board or cable connections. This unshrouded, single-row connector features 32 positions with 0.100" (2.54mm) pitch spacing and gold-plated mating contacts on phosphor bronze material. The part maintains Active product status with 766 units in current inventory.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative configurations within compatible electrical and mechanical parameters. The substitute identified in this reference maintains core compatibility through matching pitch, contact type, mounting method, and termination approach.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-132-14-F-S is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pitch spacing: 0.100" (2.54mm)
• Contact type: Male Pin
• Mounting method: Through Hole
• Termination method: Solder
• Connector style: Board to Board or Cable
• Contact shape: Square
• Shrouding configuration: Unshrouded
• Flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Number of positions (32 vs. 40)
• Contact finish composition (Gold vs. Tin)
• Contact material (Phosphor Bronze vs. Copper Alloy)
• Insulation height tolerance
• Operating temperature range
• Contact length specifications

The substitute part 4-103321-8 (TE Connectivity AMP Connectors) satisfies all mandatory matching parameters while introducing a 40-position configuration and alternative contact finishes. This substitution is valid for applications where the increased position count does not create mechanical or electrical conflicts with the receiving connector or PCB layout.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (TSW-132-14-F-S): The TSW-132-14-F-S maintains Active product status with established supply availability (766 units in stock). This part is the preferred choice for new designs and applications requiring the 32-position configuration. The gold-plated mating contacts provide enhanced corrosion resistance and contact reliability. The operating temperature range of -55°C to 125°C accommodates extended environmental specifications. ROHS3 compliance and UL94 V-0 flammability rating satisfy standard regulatory requirements.

Substitute Part Selection (4-103321-8): The 4-103321-8 substitute is applicable only when the 32-position configuration cannot be accommodated and a 40-position header is acceptable for the application. This part carries Obsolete product status, indicating discontinued manufacturing and potential future supply unavailability. The substitute's operating temperature maximum of 105°C is 20°C lower than the primary part, restricting use in high-temperature environments. The tin-plated mating contacts and copper alloy base material remain suitable for standard industrial applications. The breakaway feature provides additional mechanical flexibility not present in the primary part.

Compliance Verification: Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, satisfying standard regulatory frameworks. The identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications confirm equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 4-103321-8 (40-position) directly replace the TSW-132-14-F-S (32-position)?

A: Direct replacement is not possible without PCB layout modification. The 40-position substitute requires additional board space and mating connector accommodation. Substitution is valid only when the receiving connector and PCB design can accept the increased position count without electrical or mechanical conflicts.

Q: What is the significance of the contact finish difference (Gold vs. Tin)?

A: The primary part features gold-plated mating contacts (3.00µin thickness), providing superior corrosion resistance and contact reliability in demanding environments. The substitute uses tin plating (100.0µin thickness), which is acceptable for standard industrial applications but offers less corrosion protection. Gold plating is preferred for high-reliability, long-term storage, or corrosive environment applications.

Q: Does the insulation height difference affect compatibility?

A: The primary part insulation height is 0.100" (2.54mm) versus the substitute's 0.090" (2.29mm). This 0.010" difference may affect mating connector alignment and mechanical fit. Verification with the receiving connector specifications is required before substitution.

Q: Why is the substitute part marked as Obsolete?

A: Obsolete status indicates TE Connectivity has discontinued manufacturing of the 4-103321-8. This classification restricts its use to legacy system maintenance or repair applications. New designs must utilize the Active TSW-132-14-F-S or identify alternative current-production equivalents.

Q: What is the impact of the contact post length difference?

A: The substitute's contact post is 0.015" longer (0.125" vs. 0.110"). This variation affects solder joint formation and PCB hole engagement depth. Verification with PCB design specifications and solder process parameters is necessary to ensure proper joint quality and mechanical stability.

Q: Are both parts suitable for high-temperature applications?

A: The primary part TSW-132-14-F-S operates to 125°C, accommodating high-temperature industrial environments. The substitute 4-103321-8 is limited to 105°C maximum, restricting its use in elevated-temperature applications. Application temperature requirements must be evaluated against each part's operating range.

Q: What does the breakaway feature on the substitute part provide?

A: The 4-103321-8 includes a breakaway feature allowing individual pins or pin groups to be separated from the main header strip. This feature provides mechanical flexibility for custom connector configurations not available with the unshrouded primary part.

Q: Are inventory levels a consideration in part selection?

A: The primary part TSW-132-14-F-S has 766 units in current stock, ensuring immediate availability. The substitute 4-103321-8 shows 2828 units available but carries Obsolete status, indicating no future replenishment. For production planning, the Active primary part is the preferred long-term source.
