C&K 7301K2CME Toggle Switch 3PDT Equivalent & Substitute Parts

Part Overview

The C&K 7301K2CME 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, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The 7301K2 series provides direct substitutes with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The C&K 7301K2CME can be directly substituted with the 7301K2CSE based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Circuit configuration: 3PDT
• Current rating: 5A (AC/DC)
• Voltage ratings: 120V AC / 28V DC
• Mounting configuration: Panel mount with 6.35mm circular cutout and 1/4-40 bushing thread
• Actuator specifications: Locking lever, 17.88mm length
• Termination: PC pin
• Operating temperature range: -30°C to 85°C
• Electrical life: 100,000 cycles minimum

The primary distinction between these parts is product status and regulatory compliance, not functional or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 7301K2CSE is the direct active equivalent for the obsolete 7301K2CME. Selection between these parts is determined by regulatory and compliance requirements:

• For applications requiring RoHS compliance, the 7301K2CSE is the appropriate selection.
• For applications subject to REACH regulations, the 7301K2CSE is compliant.
• Both parts share identical electrical ratings, mechanical dimensions, and operational characteristics.
• The 7301K2CME remains available in inventory (784 pcs) for legacy system support or applications with specific non-compliance requirements.

Frequently Asked Questions (FAQ)

Q: Are the 7301K2CME and 7301K2CSE electrically interchangeable?

A: Yes. Both parts feature identical 3PDT configuration, 5A current rating, 120V AC / 28V DC voltage ratings, and 100,000-cycle electrical life. They are direct functional equivalents.

Q: What are the mechanical compatibility requirements?

A: Both parts use identical panel-mount specifications: 6.35mm circular cutout, 1/4-40 bushing thread, and PC pin termination. No mechanical modifications are required for substitution.

Q: What is the primary difference between these parts?

A: The 7301K2CSE is an active product with RoHS compliance and REACH applicability, while the 7301K2CME is obsolete and RoHS non-compliant. Functional and mechanical specifications are identical.

Q: Can the 7301K2CME be used in new designs?

A: The 7301K2CME is classified as obsolete. New designs should specify the 7301K2CSE to ensure long-term availability and regulatory compliance.

Q: Are there temperature or environmental differences?

A: Both parts operate across the identical temperature range of -30°C to 85°C and share the same moisture sensitivity level (MSL 1 - Unlimited). Environmental performance is equivalent.

Q: What is the actuator material specification?

A: Both parts feature brass actuators with chrome plating and locking lever configuration at 17.88mm length.
