TSW-104-26-L-D Equivalent & Substitute Parts

Part Overview

The TSW-104-26-L-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting in board-to-board or cable applications. This 8-position, 2-row connector features 0.100" (2.54mm) pitch mating and is terminated by solder. The part is currently discontinued at DiGi Electronics, making identification of equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSW-104-26-L-D is determined by strict equivalence in the following electrical and mechanical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions and rows (8 positions, 2 rows)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Shrouding configuration (Unshrouded)
• Contact finish at mating surface (Gold)
• Insulation material (PBT)
• Flammability rating (UL94 V-0)

The 3M 929665-09-04-I meets all these core substitution criteria and is classified as an MFR recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 3M 929665-09-04-I is suitable as a substitute for the discontinued TSW-104-26-L-D based on the following factors:

Both parts maintain identical mating pitch, row spacing, contact configuration, and mounting method. Both are unshrouded headers with solder termination and gold-plated mating contacts at equivalent thickness. Both meet UL94 V-0 flammability requirements and are RoHS and REACH compliant.

The 929665-09-04-I is currently in active production status with documented inventory availability, whereas the TSW-104-26-L-D is discontinued. The substitute part features an expanded insulation material specification (glass-filled polyester in addition to PBT) and provides a specified current rating of 2.5A.

The operating temperature range of the 929665-09-04-I (-40°C ~ 105°C) is narrower than the original part (-55°C ~ 125°C). Applications requiring operation below -40°C or above 105°C must evaluate this difference against specific design requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929665-09-04-I be used as a direct replacement for the TSW-104-26-L-D?

A: Yes, for applications within the operating temperature range of -40°C to 105°C. Both parts share identical mating pitch (2.54mm), row spacing (2.54mm), position count (8 positions, 2 rows), contact type (male pin), mounting method (through hole), and termination type (solder). Both meet UL94 V-0 flammability and RoHS compliance requirements.

Q: What is the key difference in operating temperature range?

A: The TSW-104-26-L-D operates from -55°C to 125°C, while the 929665-09-04-I operates from -40°C to 105°C. Applications requiring operation at temperatures below -40°C or above 105°C cannot use the 3M substitute without additional thermal analysis.

Q: Are the contact dimensions identical?

A: Contact length specifications differ slightly. The TSW-104-26-L-D has a mating contact length of 0.230" (5.84mm) and post length of 0.126" (3.20mm), while the 929665-09-04-I has a mating contact length of 0.235" (5.97mm) and post length of 0.145" (3.68mm). These minor variations remain within typical tolerance ranges for 2.54mm pitch connectors.

Q: What is the current rating difference?

A: The TSW-104-26-L-D does not specify a current rating in the provided data. The 929665-09-04-I specifies a current rating of 2.5A per contact. Applications requiring current specifications should confirm compatibility with actual design requirements.

Q: Are both parts RoHS compliant?

A: Yes. The TSW-104-26-L-D is ROHS3 compliant, and the 929665-09-04-I is RoHS compliant. Both are REACH unaffected.
