C&K 7401P4YCME Toggle Switch 4PDT Equivalent & Substitute Parts

Part Overview

The C&K 7401P4YCME is a panel-mounted toggle switch with 4PDT (four-pole double-throw) configuration, rated for 5A at 120V AC and 28V DC. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The switch features epoxy-sealed terminals, flat anti-rotation actuator, and PC pin termination suitable for industrial control applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7401P4YCME is determined by strict equivalence across the following critical parameters:

• Circuit configuration (4PDT)
• Switch function (On-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Flat Anti-Rotation, 6.35mm length)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Operating temperature range (-30°C to 85°C)
• Electrical life (100,000 Cycles)

Only components matching all these parameters across the C&K 7000 series are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7401P4YCSE serves as a direct functional substitute for the obsolete 7401P4YCME. Both components maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction lies in product status: the 7401P4YCSE is actively manufactured and supported, whereas the 7401P4YCME is obsolete.

For new designs and system replacements, the 7401P4YCSE is the appropriate selection. Both components satisfy RoHS compliance requirements, though the 7401P4YCSE carries REACH Affected status compared to the REACH Unaffected classification of the original part. This distinction does not affect functional compatibility but should be documented in compliance documentation for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the 7401P4YCSE directly replace the 7401P4YCME in existing assemblies?

A: Yes. The 7401P4YCSE is electrically and mechanically equivalent to the 7401P4YCME. Panel cutout dimensions, bushing thread specifications, and termination styles are identical, enabling direct substitution without mechanical redesign.

Q: What is the significance of the product status difference?

A: The 7401P4YCME is classified as obsolete, indicating C&K no longer manufactures this variant. The 7401P4YCSE remains in active production, ensuring long-term availability and supply chain continuity for new applications and maintenance stock.

Q: Are there compliance differences between these parts?

A: Both components are RoHS compliant. The 7401P4YCSE carries REACH Affected status, while the 7401P4YCME is REACH Unaffected. This distinction applies to regulatory documentation but does not affect electrical or mechanical performance.

Q: What electrical parameters must remain constant for substitution?

A: The 4PDT circuit configuration, 5A current rating, 120V AC and 28V DC voltage ratings, and 100,000-cycle electrical life must all be maintained. Any deviation from these specifications requires re-evaluation of compatibility.

Q: Are the actuator and termination specifications identical?

A: Yes. Both parts feature flat anti-rotation actuators with 6.35mm length, PC pin termination, and identical panel cutout dimensions (circular 6.35mm diameter) with 1/4-40 bushing thread.
