TSW-140-08-F-D Equivalent & Substitute Parts

Part Overview

The TSW-140-08-F-D is an 80-position rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This unshrouded header features a 0.100" (2.54mm) pitch with dual rows and solder termination. The part maintains Active product status with full RoHS3 compliance and MSL Level 1 rating, making it suitable for standard industrial and commercial applications requiring reliable interconnection across a wide operating temperature range of -55°C to 125°C.

Identifying equivalent and substitute parts is essential for supply chain continuity, design flexibility, and cost optimization while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-140-08-F-D is determined by strict alignment of 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: Solder
• Contact Shape: Square
• Operating Temperature Range: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: ROHS3 Compliant

The HTSW-140-08-F-D qualifies as a direct substitute based on complete alignment across all critical electrical and mechanical parameters. Variations in insulation material (PBT versus LCP) and insulation color do not affect functional compatibility, as both materials meet the required flammability and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-140-08-F-D and HTSW-140-08-F-D maintain Active product status with full ROHS3 compliance and identical ECCN/HTSUS classifications. Selection between these parts should be based on:

• Supply availability and lead time requirements
• Inventory levels at your component distributor
• Insulation material preference (PBT in TSW series versus LCP in HTSW series)
• Moisture sensitivity considerations (MSL Level 1 for TSW versus Not Applicable for HTSW)

Both parts satisfy identical electrical and mechanical requirements for board-to-board or cable interconnection applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can HTSW-140-08-F-D be used as a direct replacement for TSW-140-08-F-D?

A: Yes. Both parts share identical connector type, contact configuration, pitch, row spacing, mounting method, and termination. The 80-position dual-row header with 0.100" (2.54mm) spacing is mechanically and electrically compatible between both part numbers.

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

A: TSW-140-08-F-D uses Polybutylene Terephthalate (PBT) insulation, while HTSW-140-08-F-D uses Liquid Crystal Polymer (LCP) insulation. Both materials meet UL94 V-0 flammability requirements and operate across the identical temperature range of -55°C to 125°C.

Q: Are there any differences in contact finish or material?

A: No. Both parts feature identical contact materials (Phosphor Bronze), mating contact finish (Gold at 3.00µin thickness), and post finish (Tin).

Q: What does the MSL rating difference mean for component handling?

A: TSW-140-08-F-D carries MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions. HTSW-140-08-F-D is rated as Not Applicable for MSL, meaning standard handling practices apply. This difference does not affect functional compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both TSW-140-08-F-D and HTSW-140-08-F-D are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.
