TSW-124-14-F-D Equivalent & Substitute Parts Reference

Part Overview

The TSW-124-14-F-D is a classic PCB header strip manufactured by Samtec Inc., designed for through-hole board-to-board or cable connections. This unshrouded rectangular connector features 48 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. The part maintains Active product status with 1018 units in current inventory.

Substitute parts become necessary when the TSW-124-14-F-D reaches end-of-life, when design requirements demand alternative contact configurations, or when supply chain constraints require qualified alternatives. The identification of equivalent components requires strict alignment of electrical and mechanical parameters including pitch, position count, row configuration, contact materials, and operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the TSW-124-14-F-D is based on the following critical parameters that must align for functional equivalence:

Primary Matching Criteria:

• Pitch spacing: 0.100" (2.54mm) mating pitch
• Row configuration: 2-row arrangement
• Row spacing: 0.100" (2.54mm)
• Connector type: Header with male pins
• Mounting: Through-hole solder termination
• Contact shape: Square pins
• Shrouding: Unshrouded design
• Fastening type: Push-Pull mechanism

Secondary Compatibility Factors:

• Operating temperature range compatibility
• Contact material and finish specifications
• Insulation material and flammability rating
• Overall contact length and mating contact length
• Insulation height dimensions

The substitute part 4-103322-0 (TE Connectivity AMP Connectors) differs significantly in position count (80 vs. 48 positions) and row spacing (0.090" vs. 0.100"), making it incompatible for direct substitution in applications designed for the TSW-124-14-F-D. This part represents a different connector family within the rectangular connector category and cannot be used as a functional equivalent without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Assessment:

The 4-103322-0 cannot serve as a direct substitute for the TSW-124-14-F-D due to multiple critical parameter mismatches:

1. Position Count Incompatibility: The substitute part provides 80 positions versus the 48 positions of the main part. This fundamental difference prevents mechanical and electrical compatibility without complete circuit redesign.

2. Insulation Height Variance: The 0.090" insulation height of the substitute differs from the 0.100" specification of the main part, affecting PCB footprint compatibility and mating surface alignment.

3. Contact Post Length Difference: The 0.125" post length of the substitute exceeds the 0.110" specification of the main part, creating potential solder joint and through-hole clearance issues.

4. Material and Finish Specifications: The substitute employs Tin-Lead contact finish and Copper Alloy material versus the Gold-finished Phosphor Bronze of the main part, affecting contact resistance, corrosion resistance, and long-term reliability characteristics.

5. Operating Temperature Range Limitation: The substitute's maximum operating temperature of 105°C falls below the main part's 125°C specification, restricting application in high-temperature environments.

6. Product Status and Compliance: The substitute part carries Obsolete status and lacks ROHS3 compliance, whereas the main part maintains Active status with full ROHS3 certification.

Recommendation: For applications currently specified for TSW-124-14-F-D, maintain use of the main part while it remains in Active status and available inventory. The substitute part 4-103322-0 is not qualified for equivalent application and would require complete design validation if considered for alternative applications with different position and spacing requirements.

Frequently Asked Questions (FAQ)

Q: Can the 4-103322-0 be used as a direct replacement for the TSW-124-14-F-D in existing designs?

A: No. The 4-103322-0 has 80 positions compared to 48 positions in the TSW-124-14-F-D, and features different insulation height (0.090" vs. 0.100"), contact post length (0.125" vs. 0.110"), and contact materials. These differences prevent mechanical and electrical compatibility without circuit redesign.

Q: What are the critical parameters that determine if a connector can substitute for the TSW-124-14-F-D?

A: Critical parameters include: 48-position count, 2-row configuration, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, 0.100" insulation height, through-hole solder termination, male pin contact type, and push-pull fastening. Any deviation in these parameters indicates incompatibility.

Q: Why does the operating temperature range differ between the main part and the substitute?

A: The TSW-124-14-F-D operates from -55°C to 125°C, while the 4-103322-0 operates from -65°C to 105°C. These differences result from different insulation materials (PBT vs. Thermoplastic) and contact material specifications (Phosphor Bronze vs. Copper Alloy). The substitute cannot be used in applications requiring the full -55°C to 125°C range.

Q: What is the significance of the contact finish difference between Gold and Tin-Lead?

A: Gold plating on the TSW-124-14-F-D provides superior corrosion resistance, lower contact resistance, and better long-term reliability in harsh environments. Tin-Lead finish on the substitute offers lower cost but reduced corrosion resistance and higher contact resistance over extended service life.

Q: Is the 4-103322-0 suitable for new designs if the position count requirement is 80 instead of 48?

A: The 4-103322-0 carries Obsolete product status and lacks ROHS3 compliance. For new designs requiring 80-position headers with 0.100" pitch, alternative active-status connectors from current manufacturers should be evaluated rather than obsolete parts.

Q: How do the insulation height differences affect PCB design?

A: The TSW-124-14-F-D specifies 0.100" insulation height, which determines the clearance between the PCB surface and the connector body. The substitute's 0.090" height creates a 0.010" difference that affects PCB footprint design, component placement clearances, and potential interference with adjacent components.

Q: What does "Obsolete" product status mean for the substitute part?

A: Obsolete status indicates the 4-103322-0 is no longer manufactured or supported by TE Connectivity. This creates supply chain risk, eliminates manufacturer technical support, and may result in unavailable documentation or design assistance for new applications.
