TSW-110-26-L-D Equivalent & Substitute Parts

Part Overview

The TSW-110-26-L-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications requiring a 20-position, 2-row configuration with 0.100" (2.54mm) pitch. This connector is classified as discontinued at DiGi Electronics, making identification of functionally equivalent alternatives essential for ongoing design support and procurement planning. The part operates across a temperature range of -55°C to 125°C and meets UL94 V-0 flammability standards with ROHS3 compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-110-26-L-D is determined by strict alignment of the following critical parameters:

• Connector type classification (Header)
• Contact type (Male Pin)
• Mating pitch (0.100" / 2.54mm)
• Position count (20 total)
• Row configuration (2 rows)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination method (Solder)
• Contact finish at mating surface (Gold)

The substitute part 6-146256-0 (TE Connectivity AMP Connectors AMPMODU Mod II series) meets all critical substitution criteria. Both parts share identical mating pitch, position count, row configuration, and mounting characteristics. The substitute maintains gold-plated mating contacts and solder termination, ensuring electrical and mechanical compatibility in applications designed for the original TSW-110-26-L-D.

Parameter Comparison

Engineering Selection Recommendations

The 6-146256-0 substitute part is suitable for applications currently specified for the TSW-110-26-L-D based on the following factors:

Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity compared to the discontinued original part.

Dimensional variations exist between the two parts: the substitute exhibits a 0.006" (0.15mm) shorter post length and 0.010" (0.25mm) reduced insulation height. These differences fall within typical PCB design tolerances for through-hole header applications but require verification against specific board layout constraints.

The substitute part features a breakaway connector option, providing additional design flexibility not present in the original part. Operating temperature ranges differ slightly, with the substitute rated to -65°C minimum versus -55°C for the original, while the original extends to 125°C compared to 105°C for the substitute. Application temperature requirements must be evaluated against these specifications.

Both parts employ gold-plated mating contacts with tin-plated posts and maintain identical mating pitch and position configuration, supporting direct functional substitution in standard header applications.

Frequently Asked Questions (FAQ)

Q: Can the 6-146256-0 be used as a direct replacement for the TSW-110-26-L-D in existing designs?

A: The 6-146256-0 shares identical mating pitch (0.100"), position count (20), row configuration (2 rows), and row spacing (0.100"). Both employ gold-plated mating contacts and solder termination. However, dimensional differences in post length (0.006" shorter) and insulation height (0.010" shorter) require verification against PCB hole placement and clearance specifications before implementation.

Q: What are the key differences in operating temperature ranges?

A: The TSW-110-26-L-D operates from -55°C to 125°C, while the 6-146256-0 operates from -65°C to 105°C. Applications requiring operation above 105°C or below -65°C must be evaluated against the specific temperature requirements of the design.

Q: Are both parts RoHS compliant?

A: Both the TSW-110-26-L-D and 6-146256-0 are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current regulatory requirements for electronic component procurement.

Q: What is the significance of the breakaway feature on the substitute part?

A: The 6-146256-0 includes a breakaway connector option, allowing individual positions to be separated if required. The original TSW-110-26-L-D does not offer this feature. This additional capability does not affect compatibility but provides design flexibility for applications requiring modular connector configurations.

Q: How do the insulation materials differ between the two parts?

A: The TSW-110-26-L-D uses Polybutylene Terephthalate (PBT) insulation, while the 6-146256-0 uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability standards. LCP offers enhanced dimensional stability and lower moisture absorption compared to PBT.

Q: Is the substitute part currently available?

A: The 6-146256-0 maintains active product status with 2100 pieces in stock, compared to the discontinued status of the TSW-110-26-L-D, ensuring reliable procurement for new designs and ongoing production requirements.
