Substitute Part Grouping Explanation

Substitution eligibility for the TSW-113-17-S-D is determined by strict alignment of the following critical parameters:

Connector Type & Contact Configuration: Header with male pin contacts
Position Count & Row Configuration: 26 positions in 2-row arrangement
Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Termination: Through-hole solder termination
Contact Dimensions: Mating contact length of 0.620" (15.75mm) and post length of 0.110" (2.79mm)
Contact Finish: Gold-plated mating surface with tin-plated posts
Contact Material: Phosphor bronze construction
Operating Temperature: -55°C ~ 125°C range
Compliance: UL94 V-0 flammability rating and ROHS3 compliance

The HTSW-113-17-S-D meets all critical substitution criteria. Variations in insulation material (LCP versus PBT) and insulation color do not affect electrical or mechanical compatibility for standard interconnection applications.

Engineering Selection Recommendations

Both the TSW-113-17-S-D and HTSW-113-17-S-D are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. The parts are electrically and mechanically interchangeable for standard through-hole solder applications requiring 26-position, 2-row header connectors with 0.100" pitch spacing.

The primary distinction between these parts is the insulation material composition: the TSW series uses polybutylene terephthalate (PBT), while the HTSW series uses liquid crystal polymer (LCP). Both materials meet the specified operating temperature range of -55°C to 125°C and flammability requirements. Material selection should be based on application-specific environmental conditions and mechanical requirements.

Frequently Asked Questions (FAQ)

Q: Are TSW-113-17-S-D and HTSW-113-17-S-D directly interchangeable?

A: Yes. Both parts share identical electrical and mechanical specifications including connector type, position count, pitch spacing, contact dimensions, contact finishes, and operating temperature range. They are suitable for direct substitution in through-hole solder applications.

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

A: PBT (polybutylene terephthalate) and LCP (liquid crystal polymer) are both thermoplastic materials meeting UL94 V-0 flammability standards. LCP offers superior dimensional stability and lower moisture absorption compared to PBT. Material selection depends on specific application requirements for thermal cycling, humidity exposure, and mechanical stress.

Q: Do these connectors require mating with specific receptacle types?

A: These are header connectors with male pin contacts. They mate with receptacle connectors or sockets designed for 0.100" (2.54mm) pitch, 26-position, 2-row configurations. Mating component specifications must match the contact pitch, row spacing, and position count.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant, UL94 V-0 rated, and carry EAR99 ECCN classification. Compliance profiles are identical.

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

A: The TSW-113-17-S-D has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The HTSW-113-17-S-D is listed as Not Applicable for MSL, which is consistent with through-hole solder termination components that do not require moisture-controlled storage.
