TSW-102-17-L-S Equivalent & Substitute Parts

Part Overview

The TSW-102-17-L-S is a vertical rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable connections with 2 positions at 0.100" (2.54mm) pitch. This connector features male pins with gold-plated mating contacts and tin-plated posts, suitable for applications requiring push-pull fastening and solder termination. The product is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design requirements and component sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-102-17-L-S is determined by strict alignment of the following critical parameters:

Connector Type: Header (with or without breakaway capability)
Contact Type: Male Pin
Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 2
Number of Rows: 1
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
Moisture Sensitivity Level: 1 (Unlimited)

The Molex 0022284024 meets all critical substitution criteria. Variations in contact length, insulation height, and insulation material (Polyamide vs. Polybutylene Terephthalate) do not preclude substitution when the mating interface, electrical properties, and regulatory compliance remain equivalent.

Engineering Selection Recommendations

The Molex 0022284024 is a direct functional substitute for the discontinued TSW-102-17-L-S. Both connectors share identical mating pitch, contact configuration, termination method, and fastening mechanism. Both meet UL94 V-0 flammability requirements and ROHS3 compliance standards, with MSL 1 moisture sensitivity ratings.

The Molex part is currently in active production with higher inventory availability (3306 pcs vs. 1038 pcs), reducing supply chain risk. The breakaway header capability of the Molex variant provides additional design flexibility without compromising core connector functionality.

Physical differences in contact length and insulation material do not affect electrical or mechanical compatibility at the mating interface. The gold plating thickness on mating contacts (15.0µin vs. 10.0µin) on the Molex part provides equivalent or superior contact durability. Both parts are suitable for automotive, general purpose, medical, and telecommunications applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022284024 directly replace the Samtec TSW-102-17-L-S in existing designs?

A: Yes. Both connectors share the same 0.100" (2.54mm) pitch, 2-position single-row configuration, male pin contact type, and push-pull fastening. The mating interface is electrically and mechanically compatible. Physical envelope differences do not affect board-level integration.

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

A: The breakaway feature allows individual positions to be separated from the header strip if required. This does not affect standard connector operation and provides additional design flexibility for applications requiring modular configurations.

Q: Are there differences in insulation material between the two parts?

A: Yes. The Samtec part uses Polybutylene Terephthalate (PBT), while the Molex part uses glass-filled Polyamide (PA/Nylon). Both materials meet UL94 V-0 flammability requirements and are suitable for the specified operating temperature range of -55°C to 125°C.

Q: How do the contact finish thicknesses compare?

A: The Molex part has a thicker gold plating on mating contacts (15.0µin vs. 10.0µin), which provides enhanced contact durability and wear resistance. The tin plating on posts is thicker on the Molex part (100.0µin vs. unspecified on the Samtec part), supporting improved solder joint reliability.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the Samtec TSW-102-17-L-S and Molex 0022284024 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.
