TSW-109-23-F-D Equivalent & Substitute Parts

Part Overview

The TSW-109-23-F-D is an 18-position, 2-row rectangular connector header manufactured by Samtec Inc. for through-hole board-to-board or cable applications. This unshrouded header features 0.100" (2.54mm) pitch mating contacts with gold-plated mating surfaces and tin-plated solder posts. The connector operates across -55°C to 125°C and meets UL94 V-0 flammability requirements with ROHS3 compliance. Substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 5-146256-9 (TE Connectivity AMP Connectors AMPMODU Mod II series) qualifies as an equivalent based on the following critical parameters:

Matching Parameters:

• 18-position, 2-row configuration with 0.100" (2.54mm) pitch mating and row spacing
• Male pin contact type with unshrouded, through-hole solder termination
• Board-to-board or cable style with push-pull fastening
• Gold-plated mating contacts and tin-plated solder posts
• Square contact shape with UL94 V-0 flammability rating
• RoHS compliance and MSL 1 (Unlimited) moisture sensitivity level
• Active product status with full position loading

Allowable Variations:

• Insulation material: PBT (main part) versus Liquid Crystal Polymer LCP (substitute)
• Contact material: Phosphor Bronze (main part) versus Copper Alloy (substitute)
• Operating temperature: -55°C ~ 125°C (main part) versus -65°C ~ 105°C (substitute)
• Contact length specifications: Minor dimensional differences within tolerance
• Contact finish thickness: Variations in plating thickness specifications
• Packaging: Bag (main part) versus Bulk (substitute)

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-109-23-F-D and 5-146256-9 maintain active product status with full RoHS and UL94 V-0 compliance. The primary distinction lies in operating temperature range and insulation material composition. The TSW-109-23-F-D supports the extended upper temperature limit of 125°C, while the 5-146256-9 operates to 105°C maximum. For applications requiring sustained operation above 105°C, the TSW-109-23-F-D is the appropriate selection. The 5-146256-9 AMPMODU Mod II series offers breakaway connector capability and LCP insulation material, which may provide advantages in specific mechanical or thermal environments within its rated temperature range. Both parts meet identical electrical and mechanical interface requirements for 18-position, 2.54mm pitch board-to-board connections.

Frequently Asked Questions (FAQ)

Q: Can the 5-146256-9 be used as a direct replacement for the TSW-109-23-F-D?

A: The 5-146256-9 is functionally equivalent for applications operating within -65°C to 105°C. Both connectors share identical pitch, position count, contact configuration, and solder termination. Verify your application's maximum operating temperature requirement before substitution.

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

A: The TSW-109-23-F-D uses Polybutylene Terephthalate (PBT), while the 5-146256-9 uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and lower moisture absorption, while PBT provides established performance in standard industrial applications.

Q: Are there differences in contact post length?

A: Yes. The TSW-109-23-F-D has a 0.115" (2.92mm) post length, while the 5-146256-9 has a 0.120" (3.05mm) post length. This 0.005" difference may affect PCB design considerations for through-hole depth and solder joint formation. Verify PCB hole depth specifications before substitution.

Q: What does "breakaway" mean for the 5-146256-9?

A: The AMPMODU Mod II series supports breakaway configuration, allowing individual connector positions to be separated if required. The TSW-109-23-F-D does not offer this feature. This does not affect standard board-to-board mating applications.

Q: Are both parts available in the same packaging?

A: No. The TSW-109-23-F-D is supplied in Bag packaging, while the 5-146256-9 is supplied in Bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Do both connectors have the same current rating?

A: The TSW-109-23-F-D does not specify a current rating in the provided data. The 5-146256-9 is rated for 3A per contact. Consult detailed datasheets for complete electrical specifications if current capacity is a design requirement.
