Substitute Part Grouping Explanation

Substitute parts for the TSW-109-05-S-D are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (18)
• Number of rows (2)
• Pitch - mating (0.100" / 2.54mm)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)

The HTSW-109-05-S-D meets all critical substitution parameters and is classified as a direct equivalent for the TSW-109-05-S-D.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-109-05-S-D and HTSW-109-05-S-D are active production parts manufactured by Samtec Inc. and maintain full ROHS3 compliance. The parts are functionally equivalent across all critical electrical and mechanical parameters. Selection between these parts should be based on inventory availability and supply chain requirements. Both parts carry identical export classification (EAR99) and tariff codes, ensuring consistent regulatory and logistics handling. The TSW-109-05-S-D features polybutylene terephthalate (PBT) insulation material, while the HTSW-109-05-S-D uses liquid crystal polymer (LCP) insulation. Both materials meet UL94 V-0 flammability requirements and support the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Are TSW-109-05-S-D and HTSW-109-05-S-D directly interchangeable?

A: Yes. Both parts share identical electrical and mechanical specifications including connector type, contact configuration, pitch, row spacing, mounting method, and termination. They are direct substitutes for board-to-board and cable applications.

Q: What is the difference between the insulation materials used in these parts?

A: The TSW-109-05-S-D uses polybutylene terephthalate (PBT) insulation, while the HTSW-109-05-S-D uses liquid crystal polymer (LCP) insulation. Both materials satisfy UL94 V-0 flammability requirements and operate across the -55°C to 125°C temperature range.

Q: Do both parts have the same moisture sensitivity level?

A: The TSW-109-05-S-D has a moisture sensitivity level (MSL) of 1 (Unlimited). The HTSW-109-05-S-D is listed as Not Applicable for MSL, indicating no moisture sensitivity constraints.

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

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under EAR99 export control. They share the same HTSUS tariff code (8536.69.4040), ensuring consistent regulatory treatment.

Q: Can these parts be used in high-temperature applications?

A: Both parts support an operating temperature range of -55°C to 125°C. Applications requiring operation outside this range require alternative connector solutions.

Q: What contact finish specifications apply to these connectors?

A: Both parts feature gold-plated mating contacts with 30.0µin (0.76µm) thickness and tin-plated posts. Contact material is phosphor bronze for both parts.
