Key Parameters

Substitute Part Grouping Explanation

The Molex 0022284183 connector qualifies as a substitute for the TSW-118-23-L-S based on the following critical parameters:

• Connector Type & Contact Configuration: Both are unshrouded male pin headers with identical 18-position, single-row layout
• Pitch Specification: Both maintain 0.100" (2.54mm) mating pitch, ensuring mechanical and electrical compatibility
• Mounting & Termination: Both utilize through-hole solder termination with push-pull fastening
• Contact Finish: Both feature gold-plated mating surfaces and tin-plated posts
• Compliance & Status: Both are Active products with RoHS3 compliance and MSL 1 rating
• Flammability Rating: Both meet UL94 V-0 material flammability requirements

Substitution is valid where the mechanical envelope and electrical performance requirements align with these core parameters. Minor variations in contact length, insulation height, and insulation material composition do not preclude functional equivalence in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-118-23-L-S and 0022284183 maintain Active product status with full RoHS3 compliance and MSL 1 rating, confirming current manufacturing support and regulatory alignment. The Molex 0022284183 provides equivalent electrical and mechanical performance for standard through-hole applications requiring 18-position, 0.100" pitch male pin headers with solder termination.

Selection between these parts should be based on:

• Inventory Availability: The Molex substitute (1492 pcs in stock) offers higher current availability compared to the Samtec primary part (659 pcs in stock)
• Mechanical Envelope Compatibility: Minor dimensional variations in contact length and insulation height require verification against specific PCB layout and mating connector specifications
• Insulation Material Requirements: The Samtec part uses PBT insulation, while the Molex substitute uses glass-filled polyamide; material selection may impact thermal or chemical resistance in specialized applications
• Contact Finish Thickness: The Molex part provides thicker gold plating (15.0µin vs. 10.0µin), which may extend contact life in high-cycle mating applications

Frequently Asked Questions (FAQ)

Q: Are the TSW-118-23-L-S and 0022284183 mechanically interchangeable?

A: Both connectors share identical pitch (0.100"), position count (18), row configuration (1), and contact type (male pin). However, minor differences in overall contact length (0.445" vs. 0.455") and insulation height (0.100" vs. 0.090") require verification against mating connector specifications and PCB layout constraints before confirming mechanical interchangeability.

Q: What are the key electrical compatibility factors?

A: Both parts feature identical contact finish specifications (gold mating, tin post), push-pull fastening, and solder termination. Electrical performance is equivalent for standard board-to-board applications within the specified operating temperature range (-55°C ~ 125°C).

Q: Does the difference in insulation material affect performance?

A: The Samtec part uses PBT insulation while the Molex substitute uses glass-filled polyamide. Both materials meet UL94 V-0 flammability requirements. Material selection may impact thermal stability or chemical resistance in specialized environments; application-specific requirements should be evaluated.

Q: Are both parts RoHS3 compliant?

A: Yes, both the TSW-118-23-L-S and 0022284183 are RoHS3 compliant with MSL 1 rating and REACH Unaffected status, confirming compliance with current environmental and regulatory standards.

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

A: The Molex 0022284183 provides thicker gold plating on mating contacts (15.0µin vs. 10.0µin). This may provide extended contact life and improved wear resistance in applications requiring frequent mating cycles.
