TSW-108-17-L-S Equivalent & Substitute Parts

Part Overview

The TSW-108-17-L-S is a vertical rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 8-position connector operates across a wide temperature range of -55°C to 125°C and features gold-plated mating contacts with tin-plated posts. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design requirements and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-108-17-L-S is determined by strict alignment of the following critical parameters:

• Connector Type: Header (with or without breakaway feature)
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 8
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Insulation Material: Polybutylene Terephthalate (PBT) or equivalent thermoplastic
• Operating Temperature Range: -55°C ~ 125°C or greater
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The Molex 0022284084 meets these substitution criteria. Variations in contact length, insulation height, and contact finish thickness do not preclude substitution when the mating pitch, position count, and electrical/thermal specifications remain compatible.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022284084 is a qualified substitute for the TSW-108-17-L-S based on the following engineering criteria:

Compliance & Certification Alignment: Both parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification. Both are REACH unaffected and carry identical ECCN and HTSUS classifications.

Electrical & Mechanical Compatibility: The 0.100" (2.54mm) mating pitch, 8-position single-row configuration, and push-pull fastening mechanism are identical. Both employ gold-plated mating contacts with tin-plated posts, ensuring equivalent electrical performance in board-to-board and cable applications.

Product Status Advantage: The Molex part is currently active in production with 2075 units in stock, providing supply continuity for the discontinued Samtec connector.

Insulation Material Difference: The Molex substitute uses glass-filled polyamide (PA) nylon instead of PBT. Both materials meet UL94 V-0 requirements and operate across the required temperature range. The polyamide formulation provides equivalent mechanical and thermal performance for this connector class.

Contact Geometry Variation: The Molex part features shorter overall contact length (0.530" vs. 0.830") and reduced insulation height (0.090" vs. 0.100"). These dimensional differences do not affect mating compatibility or electrical function when used in standard through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022284084 directly replace the Samtec TSW-108-17-L-S in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (8), row configuration (1), and fastening mechanism (push-pull). The electrical and thermal specifications are equivalent. Physical layout compatibility depends on PCB footprint design; verify that the shorter contact length and reduced insulation height of the Molex part do not conflict with your specific board geometry.

Q: What is the significance of the "Breakaway" feature on the Molex part?

A: The breakaway feature allows individual connector positions to be separated after assembly. This does not affect compatibility with standard mating connectors or cable assemblies. The breakaway capability is an additional feature that does not compromise the connector's function as a direct substitute.

Q: Are there differences in contact finish thickness between the two parts?

A: Yes. The Molex part has 15.0µin (0.38µm) gold plating on mating contacts compared to 10.0µin (0.25µm) on the Samtec part. The Molex specification exceeds the original, providing enhanced contact durability and corrosion resistance without affecting electrical performance.

Q: Does the insulation material change from PBT to glass-filled polyamide affect performance?

A: No. Both materials are UL94 V-0 rated and operate across the identical temperature range (-55°C to 125°C). Glass-filled polyamide provides equivalent mechanical strength and thermal stability for this connector application. Material selection does not impact electrical function or reliability.

Q: What is the inventory status for the substitute part?

A: The Molex 0022284084 is active in production with 2075 units currently in stock, ensuring reliable procurement compared to the discontinued Samtec part.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance, UL94 V-0 flammability rating, MSL 1 classification, REACH unaffected status, and ECCN/HTSUS codes.
