C&K 7303P3YCLE Toggle Switch 3PDT 5A 120V Equivalent & Substitute Parts

Part Overview

The C&K 7303P3YCLE is a panel-mount toggle switch with 3PDT (three-pole, double-throw) configuration rated for 5A at 120V AC and 28V DC. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The switch features a flat anti-rotation actuator, epoxy-sealed PC pin terminals, and operates across a temperature range of -30°C to 85°C with an electrical life of 40,000 cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7303P3YCLE are identified based on strict electrical and mechanical compatibility criteria. All substitute candidates must match the following core parameters:

• 3PDT circuit configuration
• On-Off-On switch function
• 5A current rating (AC/DC)
• Minimum 120V AC voltage rating
• 28V DC voltage rating
• Panel mount configuration
• Circular 6.35mm diameter panel cutout
• 1/4-40 bushing thread
• PC pin termination
• Operating temperature range of -30°C to 85°C or better
• 40,000 cycle electrical life minimum

Substitute parts are grouped into two categories: direct manufacturer equivalents from C&K and cross-manufacturer alternatives that meet all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

C&K 7303P3YCRE is the primary direct equivalent. As an active product from the original manufacturer, it maintains identical electrical specifications and mechanical dimensions to the obsolete 7303P3YCLE. The 7303P3YCRE achieves RoHS compliance and is subject to REACH regulations, making it suitable for applications requiring modern regulatory adherence.

E-Switch 1003P3T1B1M2QEH provides cross-manufacturer compatibility with all critical electrical and mechanical parameters. This part features a standard round actuator with 10.41mm length compared to the flat anti-rotation actuator of the main part. The actuator geometry difference does not affect electrical performance but may impact panel aesthetics and tactile feedback. This part maintains ROHS3 compliance and is unaffected by REACH.

Grayhill Inc. 34A3P31B1M2QT meets all functional requirements with a 125V AC rating, which exceeds the 120V specification of the main part. Like the E-Switch alternative, it uses a standard round actuator at 10.41mm length. This part is RoHS compliant and REACH unaffected.

Selection between substitute parts should prioritize the C&K 7303P3YCRE for direct replacement applications. Cross-manufacturer alternatives are suitable when supply constraints exist or when actuator geometry differences are acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can the 7303P3YCRE directly replace the obsolete 7303P3YCLE?

A: Yes. The 7303P3YCRE maintains identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (3PDT), mechanical mounting dimensions (6.35mm panel cutout, 1/4-40 bushing thread), and termination style (PC pin). Both parts feature flat anti-rotation actuators at 11.43mm length and epoxy-sealed terminals.

Q: What is the difference between the flat anti-rotation and standard round actuators?

A: The flat anti-rotation actuator on the C&K parts (7303P3YCLE and 7303P3YCRE) prevents unintended rotation during installation and operation. The standard round actuators on the E-Switch 1003P3T1B1M2QEH and Grayhill 34A3P31B1M2QT do not include this anti-rotation feature. Both actuator types are functionally equivalent for electrical switching performance.

Q: Are the E-Switch and Grayhill parts electrically compatible?

A: Yes. Both parts meet the core electrical specifications: 3PDT configuration, On-Off-On function, 5A current rating, and minimum 120V AC voltage rating. The Grayhill part provides 125V AC rating, which exceeds the 120V requirement. Both operate across -30°C to 85°C with 40,000 cycle electrical life.

Q: What are the RoHS and REACH compliance differences?

A: The obsolete 7303P3YCLE is RoHS non-compliant and REACH unaffected. The C&K 7303P3YCRE is RoHS compliant but REACH affected. The E-Switch 1003P3T1B1M2QEH is ROHS3 compliant and REACH unaffected. The Grayhill 34A3P31B1M2QT is RoHS compliant and REACH unaffected. Selection should align with regulatory requirements for the target application and market.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed for all substitute parts. Mechanical interchangeability depends on panel cutout dimensions and actuator geometry. All parts share identical panel cutout specifications (6.35mm circular) and bushing threads (1/4-40). Actuator length differences (11.43mm for C&K parts versus 10.41mm for E-Switch and Grayhill) may affect panel clearance and should be verified for specific applications.

Q: What inventory levels are available?

A: Current inventory includes 933 units of the C&K 7303P3YCRE, 911 units of the E-Switch 1003P3T1B1M2QEH, and 934 units of the Grayhill 34A3P31B1M2QT.
