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 positions)
Row configuration (2 rows)
Row spacing (0.100" / 2.54mm)
Mounting method (Through Hole)
Termination type (Solder)
Contact finish at mating surface (Gold)
Shrouding status (Unshrouded)
Fastening type (Push-Pull)
RoHS compliance status

The substitute part 6-146256-0 (TE Connectivity AMP Connectors) meets all critical substitution criteria. Both parts share identical mating pitch, position count, row configuration, mounting type, and termination method. Both are RoHS3 compliant and feature gold-plated mating contacts with push-pull fastening. Variations in contact length, insulation material, and operating temperature range are within acceptable tolerance for equivalent functionality in standard board-to-board applications.

Engineering Selection Recommendations

Both the TSW-110-26-L-D and 6-146256-0 are active production parts with ROHS3 compliance and UL94 V-0 flammability ratings. The TSW-110-26-L-D operates across a wider temperature range (-55°C to 125°C) compared to the TE Connectivity substitute (-65°C to 105°C). Selection between these parts should be based on specific application temperature requirements. The TE Connectivity part features a breakaway connector option and provides a specified current rating of 3A. Both parts share identical mating pitch, position count, and row spacing, ensuring mechanical and electrical compatibility in standard through-hole PCB applications. Compliance certifications and regulatory status are equivalent between both options.

Frequently Asked Questions (FAQ)

Q: What determines if a connector can substitute for the TSW-110-26-L-D?

A: Substitution requires matching mating pitch (0.100" / 2.54mm), position count (20), row configuration (2 rows), row spacing (0.100" / 2.54mm), mounting type (through-hole), termination method (solder), contact type (male pin), and contact finish (gold). The connector must also be unshrouded with push-pull fastening.

Q: Are there differences in operating temperature between the main part and substitute?

A: Yes. 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 use the original Samtec part.

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

A: The TSW-110-26-L-D uses Polybutylene Terephthalate (PBT), while the 6-146256-0 uses Liquid Crystal Polymer (LCP). Both materials are UL94 V-0 rated. LCP offers superior dimensional stability and lower moisture absorption.

Q: Can the 6-146256-0 be used in applications where the TSW-110-26-L-D is specified?

A: Substitution is valid when application temperature requirements fall within -65°C to 105°C and no specific material or contact length specifications mandate the original part. Verify PCB layout compatibility due to minor differences in overall contact length (0.440" vs 0.456") and insulation height (0.090" vs 0.100").

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

A: The breakaway feature allows individual connector positions to be separated if required. This does not affect compatibility with standard applications using the full 20-position header configuration.

Q: Are both parts RoHS compliant?

A: Yes. Both the TSW-110-26-L-D and 6-146256-0 are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.
