TSW-105-26-L-D Equivalent & Substitute Parts

Part Overview

The TSW-105-26-L-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications requiring a 10-position, 2-row configuration with 0.100" (2.54mm) pitch. This connector is classified as discontinued at DiGi Electronics, making identification of compatible substitute parts essential for ongoing design support and component procurement.

The primary reason for identifying substitute parts is the discontinued product status, which necessitates alternative sourcing for new production runs, repairs, and design revisions where this connector type remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-105-26-L-D is determined by strict alignment of the following electrical and mechanical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions and rows (10 positions, 2 rows)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Insulation material compatibility (PBT or equivalent)
• Operating temperature envelope
• Regulatory compliance (RoHS, REACH, UL94 V-0)

The 3M 929665-09-05-I meets these core substitution criteria, maintaining dimensional and functional compatibility while offering active product status and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The 929665-09-05-I from 3M is a qualified substitute for the TSW-105-26-L-D based on the following engineering criteria:

Regulatory Compliance: Both parts maintain UL94 V-0 flammability rating, RoHS compliance, and REACH unaffected status, ensuring regulatory alignment for applications requiring these certifications.

Product Availability: The 3M part carries active product status with 2535 units in stock, compared to the discontinued Samtec part. This availability difference is the primary driver for substitution in new procurement scenarios.

Dimensional and Functional Compatibility: Core mechanical parameters—pitch, row spacing, number of positions, mounting type, and termination method—are identical between both parts, ensuring PCB layout and assembly process compatibility.

Operating Temperature Consideration: The TSW-105-26-L-D operates across -55°C to 125°C, while the 929665-09-05-I operates across -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must retain the original Samtec part or identify alternative solutions.

Contact Material Difference: The Samtec part uses Phosphor Bronze contacts with tin post finish, while the 3M part uses Copper Alloy contacts with gold post finish. Both configurations meet the specified gold mating surface requirement and maintain electrical performance within the stated parameters.

Frequently Asked Questions (FAQ)

Q: Can the 929665-09-05-I be used as a direct replacement in existing designs?

A: Yes, for applications operating within -40°C to 105°C. The connector maintains identical pitch, row spacing, position count, and mounting configuration. PCB footprints and mating connector specifications remain compatible. Applications requiring the extended lower temperature range of the original part (-55°C) require design review.

Q: What is the primary difference between these two connectors?

A: The primary differences are product status (discontinued vs. active), operating temperature range (-55°C to 125°C vs. -40°C to 105°C), contact material composition, and post finish. Mating surface finish, pitch, and mechanical configuration are identical.

Q: Are both parts RoHS compliant?

A: Yes. The TSW-105-26-L-D is ROHS3 compliant, and the 929665-09-05-I is RoHS compliant. Both meet regulatory requirements for restricted substance elimination.

Q: Does the difference in insulation material affect compatibility?

A: The 929665-09-05-I uses PBT with polyester and glass filler, compared to the TSW-105-26-L-D's standard PBT. Both materials maintain UL94 V-0 rating and are suitable for the same application classes. The glass-filled variant in the 3M part provides enhanced mechanical properties without affecting electrical or thermal performance within the stated operating range.

Q: What is the current rating difference?

A: The 929665-09-05-I specifies a 2.5A current rating. The TSW-105-26-L-D does not specify a current rating in the provided data. For applications requiring current rating verification, consult the original Samtec datasheet or contact the manufacturer directly.

Q: Can I use the 929665-09-05-I in applications requiring -55°C operation?

A: No. The 929665-09-05-I is rated to -40°C minimum. Applications requiring -55°C operation must use the original TSW-105-26-L-D or identify an alternative connector with matching low-temperature specifications.
