U13SD9W4LE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The U13SD9W4LE is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration manufactured by C&K in the 7000 series. This through-hole mounted switch is rated for 5A at 120V AC and 28V DC, featuring a standard round actuator with wire wrap termination and epoxy sealed terminals. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U13SD9W4LE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Through Hole)
• Actuator type and length (Standard Round, 12.45mm)
• Termination style (Wire Wrap)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)
• Base product number (U13SD9)

The U13SD9W4RE qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction is product status: U13SD9W4LE is obsolete while U13SD9W4RE is active.
