TSW-136-14-L-S Equivalent & Substitute Parts

Part Overview

The TSW-136-14-L-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 36-position, single-row connector operates at 0.100" (2.54mm) pitch and is classified as an active product with full inventory availability. The connector features unshrouded design, solder termination, and push-pull fastening suitable for board-to-board or cable interconnection.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements necessitate alternative connector configurations with compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-136-14-L-S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Pitch - Mating: 0.100" (2.54mm)
• Connector Type: Header with male pin contacts
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Number of Rows: 1

Secondary Compatibility Considerations:

• Number of Positions: The main part specifies 36 positions; substitute parts may vary in position count while maintaining the same pitch and row configuration
• Contact Finish: Variations in mating and post finishes are acceptable provided electrical performance requirements are met
• Insulation Material: Both PBT and thermoplastic materials are acceptable for this application category
• Operating Temperature Range: Substitute parts must support the operational environment of the primary application

The substitute part 4-103321-0 (TE Connectivity AMP Connectors AMPMODU Mod II series) meets these criteria with compatible pitch, connector type, mounting method, and termination approach, though it features 40 positions and differs in certain material specifications.

Parameter Comparison

Engineering Selection Recommendations

TSW-136-14-L-S (Primary Selection): The TSW-136-14-L-S remains the preferred selection for new designs and active production applications. This part maintains active product status, ROHS3 compliance, and gold-plated mating contacts that provide superior corrosion resistance and contact reliability. The operating temperature range of -55°C to 125°C accommodates extended environmental specifications. Inventory availability of 665 pieces supports immediate procurement requirements.

4-103321-0 (Substitute Selection): The 4-103321-0 serves as a functional substitute when TSW-136-14-L-S availability is constrained. This part shares critical mechanical and electrical compatibility parameters including 0.100" pitch, through-hole solder termination, and push-pull fastening. However, the following factors require consideration:

• Product Status: Classified as obsolete, indicating limited future availability
• Position Count: 40 positions versus 36 positions in the primary part; design accommodation is necessary
• Contact Finish: Tin-lead finish differs from gold plating; verify corrosion resistance requirements for the application environment
• Operating Temperature: Maximum temperature of 105°C is lower than the primary part's 125°C rating; confirm application thermal requirements
• RoHS Compliance: Not applicable status indicates this part does not meet ROHS3 standards; regulatory compliance verification is required for applicable markets

Selection of the substitute part is appropriate only when the primary part is unavailable and design modifications to accommodate 40-position configuration and lower temperature rating are feasible.

Frequently Asked Questions (FAQ)

Q: Can the 4-103321-0 be used as a direct replacement for the TSW-136-14-L-S?

A: The 4-103321-0 is mechanically and electrically compatible in terms of pitch (0.100"), connector type (header), mounting method (through-hole), and termination (solder). However, direct replacement requires design accommodation for the increased position count (40 versus 36) and verification that the lower maximum operating temperature (105°C versus 125°C) meets application requirements.

Q: What are the key differences in contact materials between these parts?

A: The TSW-136-14-L-S uses phosphor bronze contacts with gold mating finish, while the 4-103321-0 uses copper alloy contacts with tin-lead finish. Gold plating provides enhanced corrosion resistance and contact reliability in demanding environments. Tin-lead finish is suitable for standard industrial applications but may require additional environmental protection in corrosive conditions.

Q: Does the position count difference affect compatibility?

A: Yes. The TSW-136-14-L-S provides 36 positions while the 4-103321-0 provides 40 positions. Substitution requires either design modification to utilize the additional positions or physical modification to disable unused positions. PCB layout and mating connector design must accommodate the different position count.

Q: Are there compliance differences between these parts?

A: The TSW-136-14-L-S is ROHS3 compliant, while the 4-103321-0 has not applicable RoHS status. For applications requiring RoHS compliance, the primary part is mandatory. The 4-103321-0 is classified as obsolete, which may affect long-term supply chain viability.

Q: What is the impact of the insulation height difference?

A: The TSW-136-14-L-S has 0.100" insulation height while the 4-103321-0 has 0.090" insulation height. This 0.010" difference may affect mating connector clearance and PCB layout spacing. Verify that mating connectors and surrounding components accommodate this dimensional variation.

Q: Can the operating temperature ranges be considered equivalent?

A: No. The TSW-136-14-L-S operates from -55°C to 125°C, while the 4-103321-0 operates from -65°C to 105°C. The primary part supports higher maximum temperature operation. Applications requiring sustained operation above 105°C must use the primary part. The lower minimum temperature of the substitute part (-65°C versus -55°C) provides extended cold-temperature capability if required.
