C&K 7103P3DW3LE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7103P3DW3LE is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This panel-mount switch features a flat anti-rotation actuator and wire wrap termination, designed for On-Off-On switching applications. The part is classified as obsolete, making identification of active equivalent models essential for procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103P3DW3LE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Current and voltage ratings (5A AC/DC, 120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Flat Anti-Rotation, 13.21mm length)
• Termination style (Wire Wrap)
• Panel interface dimensions (Circular 6.35mm Dia, 1/4-40 bushing thread)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 cycles)

The C&K 7103P3DW3RE meets all these criteria and is classified as an active product within the same 7000 series, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7103P3DW3RE is the direct substitute for the obsolete 7103P3DW3LE. Both parts share identical electrical ratings, mechanical interfaces, and operational specifications. The primary distinction is product status: the 7103P3DW3LE is obsolete, while the 7103P3DW3RE is active and currently available.

Both parts maintain RoHS compliance and carry identical export classification (EAR99). The 7103P3DW3RE is suitable for new designs and replacement applications requiring SPDT toggle switch functionality with the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 7103P3DW3RE directly replace the 7103P3DW3LE in existing assemblies?

A: Yes. Both parts are mechanically and electrically identical. Panel cutout dimensions, bushing thread specifications, actuator geometry, and termination style are equivalent. No design modifications are required.

Q: What is the difference between these two part numbers?

A: The primary difference is product lifecycle status. The 7103P3DW3LE is obsolete, while the 7103P3DW3RE is an active product. Both are from the C&K 7000 series and share identical specifications.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant and carry the same ECCN and HTSUS classifications. The 7103P3DW3LE is RoHS3 compliant, while the 7103P3DW3RE is RoHS compliant. Both meet regulatory requirements for their respective applications.

Q: What electrical parameters must match for substitution?

A: Current rating (5A AC/DC), voltage ratings (120V AC, 28V DC), circuit configuration (SPDT), and switch function (On-Off-On) must remain constant. These parameters define the functional equivalence of toggle switches in this category.

Q: Are the panel mounting interfaces identical?

A: Yes. Both parts feature a circular 6.35mm diameter panel cutout with 1/4-40 bushing thread. Mechanical installation is identical.
