TSW-130-14-F-S Equivalent & Substitute Parts

Part Overview

The TSW-130-14-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 30 positions with 0.100" (2.54mm) pitch spacing and gold-plated mating contacts on phosphor bronze material. The component maintains Active product status with 724 units in current inventory.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative configurations within compatible electrical and mechanical parameters. The TSW-130-14-F-S can be substituted with equivalent headers that maintain critical mating pitch, contact type, mounting method, and operating temperature range specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-130-14-F-S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for PCB footprint compatibility
• Connector Type: Header with male pin contacts
• Mounting Type: Through Hole solder termination
• Contact Shape: Square pins
• Number of Rows: Single row configuration
• Material Flammability Rating: UL94 V-0 minimum

Secondary Compatibility Criteria:

• Operating Temperature Range: Must encompass or exceed -55°C ~ 125°C
• RoHS Compliance: ROHS3 Compliant status required
• Shrouding: Unshrouded configuration
• Style: Board to Board or Cable

The substitute part 4-103321-8 (TE Connectivity AMP Connectors) shares the core mating pitch, connector type, mounting method, and contact configuration. However, position count differs (40 vs. 30 positions), which affects physical footprint and board layout requirements. This difference necessitates design verification before implementation.

Engineering Selection Recommendations

Primary Selection: TSW-130-14-F-S

The TSW-130-14-F-S maintains Active product status with established supply availability (724 units in stock). This component is the preferred choice for new designs and ongoing production due to continuous manufacturer support and predictable lead times.

Substitute Selection: 4-103321-8

The 4-103321-8 may be considered only when TSW-130-14-F-S supply is unavailable. Critical considerations include:

1. Product Status Limitation: The 4-103321-8 carries Obsolete status, indicating discontinued manufacturing. This substitute should be used only for short-term supply relief or legacy system maintenance, not for new production programs.

2. Position Count Variance: The 40-position configuration requires PCB layout modification compared to the 30-position primary part. This necessitates design review and potential board revision.

3. Operating Temperature Range: The substitute's maximum operating temperature of 105°C is 20°C lower than the primary part's 125°C rating. Applications requiring the full -55°C ~ 125°C range cannot use this substitute.

4. Contact Finish Difference: Gold plating on the primary part provides superior corrosion resistance compared to the tin finish on the substitute. In high-humidity or corrosive environments, this difference may affect long-term reliability.

5. Insulation Height Variance: The 0.25mm reduction in insulation height on the substitute may affect mating connector clearance. Verify compatibility with mating receptacles before implementation.

6. Post Length Difference: The 0.39mm longer post on the substitute requires verification against PCB thickness specifications to ensure proper solder joint formation.

Frequently Asked Questions (FAQ)

Q: Can the 4-103321-8 be used as a direct drop-in replacement for the TSW-130-14-F-S?

A: No. While both components share the critical 0.100" (2.54mm) mating pitch and through-hole solder termination, the 40-position configuration of the 4-103321-8 differs from the 30-position TSW-130-14-F-S. PCB footprint modification is required. Additionally, dimensional variations in post length and insulation height require verification against your specific PCB and mating connector specifications.

Q: What is the primary reason to consider substitution?

A: Substitution becomes necessary only when the TSW-130-14-F-S experiences supply unavailability or extended lead times. The primary part maintains Active status with established inventory, making it the preferred choice for all new designs.

Q: Does the 4-103321-8 meet the same temperature operating range?

A: No. The 4-103321-8 operates from -65°C ~ 105°C, which is 20°C lower at the maximum temperature compared to the TSW-130-14-F-S range of -55°C ~ 125°C. Applications requiring operation at temperatures above 105°C cannot use this substitute.

Q: Are both parts RoHS compliant?

A: Yes. Both the TSW-130-14-F-S and 4-103321-8 are ROHS3 Compliant and UL94 V-0 rated, meeting current environmental and flammability standards.

Q: What is the significance of the gold versus tin contact finish?

A: The TSW-130-14-F-S features gold-plated mating contacts, which provide superior corrosion resistance and lower contact resistance compared to the tin finish on the 4-103321-8. In applications exposed to moisture, salt spray, or other corrosive environments, the gold finish offers enhanced long-term reliability.

Q: Why is the 4-103321-8 listed as Obsolete?

A: Obsolete status indicates that TE Connectivity has discontinued manufacturing of this component. While existing inventory may be available through distributors, no new production is occurring. This status makes the 4-103321-8 unsuitable for long-term production programs or new designs.

Q: How do the dimensional differences affect PCB design?

A: The 4-103321-8 has a 0.39mm longer post (0.125" vs. 0.110") and 0.25mm lower insulation height (0.090" vs. 0.100"). These differences may affect solder joint formation and mating connector clearance. Verify these dimensions against your PCB thickness and mating receptacle specifications before implementation.

Q: Can I use the 4-103321-8 for a 30-position application by leaving 10 positions unloaded?

A: While physically possible, this approach is not recommended. The 40-position header is designed as a complete assembly. Using only 30 of 40 positions introduces unnecessary cost, inventory complexity, and potential assembly errors. The TSW-130-14-F-S remains the appropriate choice for 30-position applications.
