TSW-113-14-F-S Equivalent & Substitute Parts

Part Overview

The TSW-113-14-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 header features 13 positions at 0.100" (2.54mm) pitch with gold-plated mating contacts and tin-plated posts. The component maintains Active product status with 787 units currently in stock.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative configurations that maintain electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-113-14-F-S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Pitch - Mating: 0.100" (2.54mm) - must match exactly for mechanical interchangeability
• Connector Type: Header with male pin contacts
• Mounting Type: Through Hole solder termination
• Contact Shape: Square profile
• Number of Rows: Single row configuration

Secondary Compatibility Factors:

• Overall Contact Length: 0.530" (13.46mm) ± tolerance
• Insulation Height: 0.100" (2.54mm) nominal
• Contact Material: Phosphor Bronze or equivalent copper alloy
• Insulation Material: PBT or thermoplastic equivalent
• Operating Temperature Range: Must encompass or match -55°C ~ 125°C
• Flammability Rating: UL94 V-0 compliance

The substitute part 4-103321-0 (TE Connectivity AMP Connectors) shares the fundamental pitch, connector type, mounting method, and contact configuration. However, this part is classified as Obsolete and exhibits differences in position count (40 vs. 13), insulation height (0.090" vs. 0.100"), contact finish specifications, and operating temperature range (-65°C ~ 105°C vs. -55°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

TSW-113-14-F-S (Primary Selection): The TSW-113-14-F-S maintains Active product status with confirmed inventory availability (787 units in stock). This component is ROHS3 compliant and operates across the extended temperature range of -55°C ~ 125°C. Selection of this part ensures long-term supply continuity and regulatory compliance for applications requiring RoHS certification.

4-103321-0 (Conditional Substitute): The 4-103321-0 is classified as Obsolete and carries "Not applicable" RoHS status, indicating this component does not meet current regulatory requirements. The operating temperature maximum of 105°C is 20°C below the primary part specification. The insulation height differential of 0.010" and post length variation of 0.015" require PCB layout verification. The 40-position configuration necessitates design modification if the application requires exactly 13 positions. This substitute is suitable only for legacy system maintenance where regulatory compliance is not required and thermal operating conditions remain below 105°C.

Compliance Considerations: Applications subject to RoHS3 requirements must use the TSW-113-14-F-S. The substitute part's obsolete status and non-applicable RoHS designation make it unsuitable for new designs or products requiring regulatory certification.

Frequently Asked Questions (FAQ)

Q: Can the 4-103321-0 directly replace the TSW-113-14-F-S in a new design?

A: No. The 4-103321-0 is Obsolete and does not meet ROHS3 compliance requirements. New designs must use the TSW-113-14-F-S to ensure regulatory compliance and long-term supply availability.

Q: What is the significance of the 0.100" insulation height difference between these parts?

A: The TSW-113-14-F-S specifies 0.100" (2.54mm) insulation height while the 4-103321-0 specifies 0.090" (2.29mm). This 0.010" difference affects the vertical profile of the assembled connector on the PCB. PCB layout and mating connector clearances must be verified before substitution.

Q: Are the contact finishes interchangeable?

A: The TSW-113-14-F-S uses gold-plated mating contacts while the 4-103321-0 uses tin-lead finish. Gold plating provides superior corrosion resistance and contact reliability. Tin-lead finish is acceptable for non-critical applications but does not provide equivalent long-term performance characteristics.

Q: What does the 40-position configuration of the 4-103321-0 mean for a 13-position application?

A: The 4-103321-0 is a 40-position header strip. If only 13 positions are required, the component can be mechanically broken away to the desired length due to its Breakaway connector type designation. However, this requires manual modification and introduces process variability not present with the purpose-designed 13-position TSW-113-14-F-S.

Q: Why is the operating temperature range important for substitution?

A: The TSW-113-14-F-S operates from -55°C to 125°C while the 4-103321-0 operates from -65°C to 105°C. Applications requiring operation above 105°C cannot use the substitute part. The primary part's extended upper temperature limit of 125°C is critical for high-temperature industrial and automotive applications.

Q: Is the post length difference between 0.110" and 0.125" significant?

A: Yes. The post length affects solder joint formation and PCB hole engagement. The 0.015" difference requires verification that PCB hole depth and solder pad design accommodate the longer post of the 4-103321-0 without creating assembly or reliability issues.

Q: What does "Obsolete" product status mean for the 4-103321-0?

A: Obsolete status indicates the manufacturer has discontinued production. While existing inventory may be available, future supply cannot be guaranteed. New designs should not depend on obsolete components due to supply uncertainty and lack of manufacturer support.
