Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-140-28-G-D is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (80)
• 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)
• Contact geometry (Square shape)
• Contact finish (Gold on mating surface)
• Contact material (Phosphor Bronze)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)

The TSW-140-28-G-D meets all critical substitution criteria. Variations in insulation material (LCP vs. PBT) and insulation color do not affect electrical or mechanical interface compatibility. Both parts maintain identical contact geometry, pitch spacing, and thermal performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both HTSW-140-28-G-D and TSW-140-28-G-D are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

• Insulation material requirements: HTSW series uses Liquid Crystal Polymer (LCP) insulation; TSW series uses Polybutylene Terephthalate (PBT) insulation. Both materials meet the specified flammability rating and operating temperature range.
• Visual identification needs: HTSW features natural-colored insulation; TSW features black insulation.
• Inventory availability: Both parts maintain active stock levels suitable for production deployment.

The electrical and mechanical interface characteristics are identical, ensuring direct substitution capability in applications where the connector interface is the primary design constraint.

Frequently Asked Questions (FAQ)

Q: Can TSW-140-28-G-D replace HTSW-140-28-G-D in existing designs?

A: Yes. Both parts maintain identical contact pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), number of positions (80), contact geometry, and electrical performance specifications. The connector interface is fully compatible.

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

A: HTSW-140-28-G-D uses Liquid Crystal Polymer (LCP) insulation with natural color. TSW-140-28-G-D uses Polybutylene Terephthalate (PBT) insulation with black color. Both materials meet UL94 V-0 flammability requirements and operate across the -55°C to 125°C temperature range.

Q: Are both parts RoHS compliant?

A: Yes. Both HTSW-140-28-G-D and TSW-140-28-G-D are ROHS3 compliant.

Q: What is the contact finish specification for both parts?

A: Both parts feature gold-plated mating contacts with 10.0µin (0.25µm) thickness and gold-plated posts with 3.00µin (0.076µm) thickness. Contact material is phosphor bronze for both parts.

Q: Are there any thermal performance differences between these parts?

A: No. Both parts operate across the identical temperature range of -55°C to 125°C and maintain equivalent thermal performance characteristics.

Q: What mounting configuration do these connectors support?

A: Both parts are through-hole mounted connectors with solder termination, designed for board-to-board or cable applications using push-pull fastening.
