TSW-104-17-L-S Equivalent & Substitute Parts

Part Overview

The TSW-104-17-L-S is a vertical rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting with 4 positions at 0.100" (2.54mm) pitch. This connector is classified as discontinued at DiGi Electronics, making identification of functionally equivalent alternatives necessary for ongoing design support and component procurement.

Substitute Part Grouping Explanation

Substitution of the TSW-104-17-L-S is determined by the following critical parameters:

Connector Type & Contact Configuration: Header with male pins, 4 positions, single row
Pitch Specification: 0.100" (2.54mm) mating pitch is the primary compatibility criterion
Mounting & Termination: Through-hole solder termination with push-pull fastening
Contact Finish: Gold-plated mating surface with tin-plated posts
Environmental Compliance: ROHS3 compliance and UL94 V-0 flammability rating

The Molex part number 0022284044 satisfies these core substitution criteria. Both connectors share identical pitch, position count, mounting method, and compliance certifications. Variations in contact length and insulation material do not preclude functional equivalence within standard PCB design tolerances.

Engineering Selection Recommendations

The Molex 0022284044 is an active product with current manufacturing status, providing supply chain continuity for the discontinued TSW-104-17-L-S. Both connectors meet ROHS3 compliance and UL94 V-0 flammability requirements.

The primary design consideration is contact length variation. The Molex substitute features shorter mating contact length (0.320" versus 0.620") and reduced overall contact length (0.530" versus 0.830"). This difference affects mating depth and may require PCB layout verification to ensure proper connector engagement and clearance within the application enclosure.

Both connectors maintain identical pitch, position count, and solder termination specifications, supporting direct PCB footprint compatibility. The Molex part includes breakaway capability, providing additional design flexibility for applications requiring modular connector configurations.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022284044 be used as a direct replacement for the TSW-104-17-L-S?

A: Yes, for applications where the shorter contact length of the Molex part is compatible with the mating connector depth and PCB layout. The 0.100" (2.54mm) pitch and 4-position configuration are identical, and both connectors use solder termination with push-pull fastening.

Q: What is the impact of the different insulation materials?

A: The TSW-104-17-L-S uses PBT (Polybutylene Terephthalate), while the Molex 0022284044 uses glass-filled polyamide (PA/Nylon). Both materials meet UL94 V-0 flammability requirements and are suitable for the specified operating temperature range. Material selection does not affect electrical performance or connector compatibility.

Q: Are there differences in contact finish specifications?

A: The Molex part has a slightly thicker gold plating on the mating contact (15.0µin versus 10.0µin) and thicker tin plating on the post (100.0µin versus unspecified). These variations remain within standard connector manufacturing tolerances and do not affect functional compatibility.

Q: What is the significance of the breakaway feature on the Molex connector?

A: The breakaway capability allows individual positions to be separated from the header strip if required by the application. This feature provides design flexibility but does not affect standard connector operation when used as a complete 4-position header.

Q: Are both connectors suitable for the same environmental conditions?

A: Both connectors are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The TSW-104-17-L-S specifies -55°C ~ 125°C operating temperature. The Molex part does not provide an explicit operating temperature specification in the available data, requiring verification against application requirements.
