C&K 7301SPDCME Toggle Switch 3PDT Equivalent & Substitute Parts

Part Overview

The C&K 7301SPDCME 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 identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations. The switch features anti-rotation actuator design, epoxy-sealed terminals, and PC pin termination suitable for industrial control applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7301SPDCME are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Circuit configuration (3PDT)
• Switch function (On-On)
• Mounting type (Panel Mount)
• Termination style (PC Pin)
• Bushing thread specification (1/4-40)
• Panel cutout dimensions (Circular - 6.35mm Dia)

Electrical Performance Criteria:

• Current rating minimum 5A (AC/DC)
• Voltage rating minimum 120V AC and 28V DC
• Operating temperature range encompassing -30°C to 85°C

Acceptable Variations:

• Actuator type (Anti-Rotation vs. Flatted) - both compatible with panel mount interface
• Actuator length variance within mechanical envelope
• Electrical life rating (minimum 60,000 cycles acceptable)
• RoHS and REACH compliance status (compliance preferred for new designs)

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Preferred): The C&K 7301SPDCSE is the primary substitute for the obsolete 7301SPDCME. Both parts share identical electrical ratings, mechanical dimensions, and circuit configuration. The 7301SPDCSE is currently in active production status with 748 units in stock. This part achieves RoHS compliance and REACH affected status, making it suitable for applications requiring modern regulatory adherence.

Alternative Substitute: The Electroswitch A323P31DCQ provides functional equivalence with the following considerations: current rating is increased to 6A (exceeding the 5A requirement), AC voltage rating is 125V (5V higher than specified), and operating temperature range extends to 90°C. Electrical life is rated at 60,000 cycles, which is lower than the main part specification of 100,000 cycles. Panel cutout dimensions are not specified for this part. The A323P31DCQ achieves RoHS compliance; REACH status is vendor-undefined.

Compliance Considerations: For new designs or systems requiring regulatory compliance, the 7301SPDCSE is the recommended choice due to confirmed RoHS compliance and REACH affected status. The A323P31DCQ may be selected where higher current capacity or extended temperature range provides system benefits, provided mechanical fit is confirmed through dimensional verification.

Frequently Asked Questions (FAQ)

Q: Can the 7301SPDCSE directly replace the obsolete 7301SPDCME without circuit modification? A: Yes. The 7301SPDCSE maintains identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (3PDT), mechanical mounting interface (1/4-40 bushing thread, 6.35mm circular cutout), and termination style (PC Pin). No circuit or panel modifications are required.

Q: What are the key differences between the C&K 7301SPDCSE and Electroswitch A323P31DCQ? A: The primary differences are: (1) current rating—A323P31DCQ is rated 6A versus 5A for 7301SPDCSE; (2) AC voltage rating—A323P31DCQ is 125V versus 120V; (3) electrical life—A323P31DCQ is 60,000 cycles versus 100,000 cycles; (4) actuator type—A323P31DCQ uses flatted actuator versus anti-rotation for 7301SPDCSE; (5) panel cutout dimensions are not specified for A323P31DCQ. Both maintain 3PDT configuration, On-On function, and 1/4-40 bushing thread compatibility.

Q: Is the A323P31DCQ suitable for applications requiring 100,000 cycle electrical life? A: The A323P31DCQ is rated for 60,000 cycles, which is below the 100,000 cycle specification of the 7301SPDCME and 7301SPDCSE. Applications with electrical life requirements exceeding 60,000 cycles should use the 7301SPDCSE.

Q: What is the impact of RoHS compliance status on part selection? A: The 7301SPDCME is RoHS non-compliant. The 7301SPDCSE and A323P31DCQ are both RoHS compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, either the 7301SPDCSE or A323P31DCQ must be selected.

Q: Are panel cutout dimensions identical across all three parts? A: The 7301SPDCME and 7301SPDCSE both specify circular 6.35mm diameter cutouts with 1/4-40 bushing threads. Panel cutout dimensions are not specified for the A323P31DCQ. Physical verification is required before substituting the A323P31DCQ to confirm mechanical fit within existing panel openings.

Q: Can the A323P31DCQ be used in applications rated for 120V AC? A: Yes. The A323P31DCQ is rated for 125V AC, which exceeds the 120V AC requirement. The part is electrically suitable for 120V AC applications.
