Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7401P4YW5ME 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 (Wire Wrap)
• 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)

The C&K 7401P4YW5SE meets all these criteria and qualifies as a direct substitute. The primary distinction is product status: the 7401P4YW5SE is active production, whereas the 7401P4YW5ME is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7401P4YW5SE is the direct substitute for the obsolete 7401P4YW5ME. Both components maintain identical electrical and mechanical specifications across all critical parameters.

Selection between these parts should be based on:

• Supply availability: The 7401P4YW5SE is in active production with current inventory availability, whereas the 7401P4YW5ME is obsolete with limited remaining stock.
• Regulatory compliance: Both parts meet RoHS requirements. The 7401P4YW5SE is REACH Affected, while the 7401P4YW5ME is REACH Unaffected. Compliance obligations depend on end-use application and regional requirements.
• Long-term support: Active production status of the 7401P4YW5SE ensures continued availability for future procurement cycles.

Frequently Asked Questions (FAQ)

Q: Can the 7401P4YW5SE directly replace the 7401P4YW5ME in existing designs?

A: Yes. The 7401P4YW5SE is electrically and mechanically equivalent. Panel cutout dimensions, bushing thread specifications, actuator geometry, and all electrical ratings are identical. No design modifications are required.

Q: What is the difference between these two part numbers?

A: The primary difference is product lifecycle status. The 7401P4YW5ME is obsolete; the 7401P4YW5SE is active production. Both are C&K 7000 series 4PDT toggle switches with identical functional specifications.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant. The 7401P4YW5ME is REACH Unaffected; the 7401P4YW5SE is REACH Affected. Verify REACH compliance requirements for your specific application and end-use region.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is based on matching circuit configuration (4PDT), switch function (On-On), current and voltage ratings (5A at 120V AC / 28V DC), mounting type (Panel Mount), actuator specifications (Flat Anti-Rotation, 6.35mm), termination style (Wire Wrap), panel cutout dimensions (Circular - 6.35mm Dia), bushing thread (1/4-40), operating temperature range (-30°C to 85°C), and electrical life (100,000 Cycles).

Q: Is the wire wrap termination compatible with standard PCB assembly processes?

A: Wire wrap termination is a discrete wiring connection method. Compatibility depends on your assembly process and panel design. Verify that your wiring infrastructure and connection methodology support wire wrap termination.
