TSW-136-23-L-S Equivalent & Substitute Parts

Part Overview

The TSW-136-23-L-S is an active 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 commonly used in board-to-board and cable interconnect applications across industrial, telecommunications, and general-purpose electronics. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, optimize procurement costs, and maintain design compatibility across manufacturing cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-136-23-L-S is determined by strict alignment of the following critical parameters:

• Connector Type: Header (standard or breakaway variants acceptable)
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm) (exact match required)
• Number of Positions: 36 (exact match required)
• Number of Rows: 1 (exact match required)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The Molex 0022284363 meets all critical substitution criteria. Minor variations in contact length, insulation height, and insulation material composition do not preclude functional equivalence in standard board-to-board interconnect applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-136-23-L-S and the Molex 0022284363 are active products with ROHS3 compliance and UL94 V-0 flammability certification. The Molex substitute maintains electrical and mechanical compatibility through identical pitch, position count, contact type, and fastening mechanism. The Molex part features slightly increased contact finish thickness on the mating surface (15.0µin versus 10.0µin) and a thicker post finish (100.0µin specified), which provides enhanced durability in high-cycle mating applications. The insulation material composition differs (PBT versus glass-filled polyamide), but both materials meet the same flammability standard. Selection between these parts should be based on supply availability, lead time requirements, and specific application environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022284363 be used as a direct replacement for the TSW-136-23-L-S?

A: Yes. Both connectors share identical pitch (0.100"), position count (36), row configuration (1), contact type (male pin), mounting method (through hole), and termination (solder). The push-pull fastening mechanism is identical. Mechanical and electrical compatibility is maintained.

Q: What are the differences in contact dimensions?

A: The Molex part has slightly longer mating contacts (0.240" versus 0.230") and post contacts (0.125" versus 0.115"), resulting in a 0.010" greater overall contact length. These dimensional differences are within typical tolerance ranges for standard board-to-board interconnect applications and do not affect functional compatibility.

Q: Does the insulation material difference affect performance?

A: Both materials (PBT and glass-filled polyamide) meet UL94 V-0 flammability requirements. The glass-filled polyamide in the Molex part provides enhanced mechanical strength. Material selection should be evaluated based on specific application requirements for thermal cycling, chemical exposure, or mechanical stress.

Q: Are both parts RoHS compliant?

A: Yes. Both the TSW-136-23-L-S and the Molex 0022284363 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronics manufacturing.

Q: What is the significance of the contact finish thickness difference?

A: The Molex part specifies higher gold plating thickness on the mating surface (15.0µin versus 10.0µin) and includes a specified tin finish thickness on the post (100.0µin). These specifications indicate enhanced contact durability and are suitable for applications requiring extended mating cycles or higher reliability margins.

Q: Are there any packaging or inventory considerations?

A: Both parts are supplied in bulk packaging. The Molex part has significantly higher inventory availability (37,245 pieces versus 1,029 pieces), which may influence procurement decisions for high-volume production or rapid delivery requirements.
