TSW-104-26-F-S Equivalent & Substitute Parts

Part Overview

The TSW-104-26-F-S is an active rectangular connector header manufactured by Samtec Inc. This through-hole vertical header features 4 positions with 0.100" (2.54mm) pitch spacing and is designed for board-to-board or cable applications. The connector utilizes solder termination with push-pull fastening and operates across the temperature range of -55°C to 125°C. Finding equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate alternative sourcing strategies while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TSW-104-26-F-S are identified based on strict alignment with the following critical parameters:

• Connector Type: Header (with or without breakaway feature)
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 4
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Insulation Material: Polybutylene Terephthalate (PBT) or compatible dielectric materials
• Material Flammability Rating: UL94 V-0

The 3M 929647-09-04-I meets these core substitution criteria. Both parts share identical mating pitch, position count, row configuration, mounting method, and termination approach. Both are active products with UL94 V-0 flammability ratings and PBT-based insulation systems.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-104-26-F-S and 929647-09-04-I are active products with current manufacturing support. Selection between these parts should be based on the following considerations:

The TSW-104-26-F-S operates across a wider temperature range (-55°C to 125°C) compared to the 929647-09-04-I (-40°C to 105°C). Applications requiring operation below -40°C or above 105°C must use the Samtec part.

The 929647-09-04-I features a breakaway connector design, which may provide additional flexibility in certain assembly or field-replacement scenarios. The 3M part also includes a current rating specification of 2.5A, whereas the Samtec part does not specify current rating in the provided data.

Both parts maintain UL94 V-0 flammability compliance and RoHS compliance status. The Samtec part is ROHS3 compliant, while the 3M part is RoHS compliant. Both are suitable for applications requiring halogen-free, flame-retardant insulation systems.

Contact geometry differences exist: the 929647-09-04-I has slightly longer mating and post contact lengths (0.235" and 0.145" respectively) compared to the TSW-104-26-F-S (0.230" and 0.126" respectively). These dimensional variations are within typical connector tolerance ranges and do not preclude substitution in standard board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Can the 929647-09-04-I directly replace the TSW-104-26-F-S in all applications?

A: Direct substitution is possible for applications operating within the 929647-09-04-I temperature range of -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must use the TSW-104-26-F-S due to its extended temperature specification of -55°C to 125°C.

Q: What is the significance of the breakaway feature on the 3M 929647-09-04-I?

A: The breakaway feature allows individual positions to be separated from the connector body after assembly. This design characteristic does not affect electrical or mechanical compatibility with standard mating connectors but may provide additional flexibility in certain manufacturing or field-service scenarios.

Q: Are there differences in contact finish that affect compatibility?

A: The TSW-104-26-F-S uses tin finish on the post (solder tail), while the 929647-09-04-I uses gold finish on the post. Both finishes are standard for solder termination and do not affect electrical compatibility. The choice between tin and gold post finishes is typically driven by solderability preferences and PCB assembly process requirements.

Q: Do the contact length differences affect mechanical fit?

A: The contact length variations between the two parts (0.230" versus 0.235" for mating contact, and 0.126" versus 0.145" for post contact) fall within standard connector tolerance ranges. These differences do not preclude mechanical or electrical compatibility in standard through-hole PCB applications.

Q: Which part should be selected for high-temperature applications?

A: The TSW-104-26-F-S is the appropriate choice for applications requiring operation above 105°C, as it is rated to 125°C. The 929647-09-04-I is limited to 105°C maximum operating temperature.

Q: Are both parts RoHS compliant?

A: Yes. The TSW-104-26-F-S is ROHS3 compliant, and the 929647-09-04-I is RoHS compliant. Both parts meet regulatory requirements for halogen-free, lead-free construction.
