TSW-109-26-L-D Equivalent & Substitute Parts

Part Overview

The TSW-109-26-L-D is an 18-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 male pin contacts and solder termination. The part is currently active in production with full inventory availability. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific material or performance characteristics are required for particular applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-109-26-L-D is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pin contacts
• Position Count & Row Configuration: 18 positions arranged in 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Contact Geometry: Square contact shape with specified mating and post lengths
• Environmental Compliance: UL94 V-0 flammability rating and ROHS3 compliance
• Operating Temperature: -55°C to 125°C range

The HTSW-109-26-L-D meets all critical substitution criteria. Variations in insulation material (Liquid Crystal Polymer vs. Polybutylene Terephthalate) and insulation color do not affect electrical or mechanical compatibility when all other parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-109-26-L-D and HTSW-109-26-L-D are active production parts manufactured by Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. The parts are electrically and mechanically interchangeable based on identical pitch, position count, contact geometry, and operating temperature specifications.

The primary distinction between these parts is the insulation material composition. The TSW-109-26-L-D uses Polybutylene Terephthalate (PBT) with black insulation, while the HTSW-109-26-L-D uses Liquid Crystal Polymer (LCP) with natural insulation. Both materials meet the same flammability and compliance requirements. Selection between these parts should be based on application-specific material requirements, inventory availability, and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Are TSW-109-26-L-D and HTSW-109-26-L-D electrically interchangeable?

A: Yes. Both parts feature identical electrical specifications including contact material (phosphor bronze), contact finish (gold mating surface, tin post), pitch (0.100"), position count (18), and operating temperature range (-55°C to 125°C).

Q: What is the difference between these two part numbers?

A: The primary differences are insulation material (PBT vs. LCP) and insulation color (black vs. natural). All mechanical and electrical parameters remain identical.

Q: Can I substitute HTSW-109-26-L-D for TSW-109-26-L-D in my PCB design?

A: Yes. The parts share identical footprint requirements, pitch spacing, contact geometry, and mounting specifications. No PCB redesign is necessary.

Q: Are both parts RoHS compliant?

A: Yes. Both TSW-109-26-L-D and HTSW-109-26-L-D are ROHS3 compliant with UL94 V-0 flammability certification.

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

A: TSW-109-26-L-D has MSL 1 (Unlimited). HTSW-109-26-L-D is listed as Not Applicable for MSL.

Q: Which part should I select for high-temperature applications?

A: Both parts operate across the identical temperature range of -55°C to 125°C. Selection should be based on material preference and availability rather than thermal performance.
