TSW-104-22-S-S-NA Equivalent & Substitute Parts

Part Overview

The TSW-104-22-S-S-NA is a rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle mounting applications. This 4-position connector operates at 0.100" (2.54mm) pitch and features male pin contacts with gold-plated mating surfaces and tin-plated posts. The part is Active in product status with ROHS3 compliance and UL94 V-0 flammability rating. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, allowing for design flexibility and supply chain alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TSW-104-22-S-S-NA are qualified based on the following critical parameters that determine functional equivalence:

• Connector Type & Contact Configuration: Header with male pin contacts
• Position Count & Pitch: 4 positions at 0.100" (2.54mm) mating pitch
• Mounting Orientation: Through hole, right-angle mounting
• Termination Method: Solder termination
• Contact Materials & Finishes: Gold-plated mating surface (30.0µin thickness) and tin-plated posts
• Operating Temperature Range: -55°C ~ 125°C
• Compliance Standards: ROHS3 compliant, UL94 V-0 flammability rating

The identified substitutes maintain these core parameters while allowing variation in insulation material composition and color, which do not affect electrical or mechanical interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status with ROHS3 compliance and UL94 V-0 flammability certification. The TSW-104-22-S-S-NA and TSW-104-22-S-S-RA are identical in insulation material (PBT), height (0.119"), color (Black), and moisture sensitivity level, differing only in series designation. The HTSW-104-22-S-S-RA employs Liquid Crystal Polymer (LCP) insulation with a marginally increased height (0.122") and Natural color, with MSL listed as Not Applicable. All three connectors are electrically and mechanically compatible for board-level through-hole applications requiring 4-position, 2.54mm pitch header connections with gold-plated mating contacts.

Frequently Asked Questions (FAQ)

Q: Can TSW-104-22-S-S-NA be directly replaced with TSW-104-22-S-S-RA?

A: Yes. Both parts share identical electrical and mechanical specifications including contact configuration, pitch, mounting type, contact finishes, operating temperature range, and compliance certifications. The parts differ only in series designation within the same product family.

Q: What is the difference between PBT and LCP insulation materials in these connectors?

A: The TSW-104-22-S-S-NA and TSW-104-22-S-S-RA use Polybutylene Terephthalate (PBT) insulation, while the HTSW-104-22-S-S-RA uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements. The insulation height difference is 0.003" (0.08mm), which may affect board layout considerations in space-constrained applications.

Q: Are all three parts RoHS compliant?

A: Yes. All three connectors are ROHS3 compliant and carry the same ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. The HTSW-104-22-S-S-RA lists MSL as Not Applicable, indicating no moisture sensitivity constraints for that variant.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: The TSW-104-22-S-S-NA and TSW-104-22-S-S-RA are direct mechanical and electrical equivalents with identical footprints. The HTSW-104-22-S-S-RA has a 0.003" greater insulation height, which should be verified against PCB layout constraints before substitution.
