C&K 7401MDV2KE Toggle Switch 4PDT Equivalent & Substitute Parts

Part Overview

The C&K 7401MDV2KE is a 4PDT (four-pole double-throw) toggle switch designed for panel mount applications with a 0.4VA current rating at 20V AC/DC. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The switch features epoxy sealed terminals, a standard round actuator, and is rated for 100,000 electrical cycles across an operating temperature range of -30°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7401MDV2KE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (4PDT)
• Switch function (On-On)
• Current and voltage ratings (0.4VA at 20V AC/DC)
• Mounting type (Panel Mount)
• Mechanical interface (Standard round actuator, 6.86mm length, 6.35mm circular panel cutout, 1/4-40 bushing thread)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life rating (100,000 cycles)

The C&K 7401MDV2PE meets all these criteria and qualifies as a direct functional equivalent. Both components share identical electrical specifications, mechanical dimensions, and environmental ratings within the 7000 series toggle switch family.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7401MDV2PE is the recommended substitute for the obsolete 7401MDV2KE. Both components maintain identical electrical and mechanical specifications, ensuring direct functional compatibility in panel mount applications requiring 4PDT switching at 0.4VA and 20V ratings.

The primary distinction between these parts is product lifecycle status: the 7401MDV2KE is obsolete, while the 7401MDV2PE maintains active production status. This transition ensures continued component availability and supply chain reliability for new designs and system maintenance.

Both parts are RoHS compliant, meeting environmental regulatory requirements. The 7401MDV2PE carries RoHS Compliant certification, while the 7401MDV2KE is ROHS3 Compliant. Both components are REACH Unaffected or REACH Affected respectively, with identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications.

Frequently Asked Questions (FAQ)

Q: Can the 7401MDV2PE directly replace the 7401MDV2KE in existing applications?

A: Yes. The 7401MDV2PE provides direct functional equivalence across all electrical, mechanical, and environmental parameters. No circuit modifications or mechanical redesign is required for substitution.

Q: What are the key compatibility factors for this toggle switch substitution?

A: Compatibility is determined by matching circuit configuration (4PDT), switch function (On-On), current/voltage ratings (0.4VA at 20V AC/DC), panel mount interface (6.35mm circular cutout with 1/4-40 bushing thread), PC pin termination, and operating temperature range (-30°C to 85°C).

Q: Why is the 7401MDV2KE classified as obsolete?

A: Obsolescence reflects the component's removal from active manufacturing. The 7401MDV2PE represents the current production equivalent within the C&K 7000 series toggle switch family.

Q: Are there any compliance differences between these parts?

A: Both components meet RoHS environmental standards. The 7401MDV2PE is designated RoHS Compliant, while the 7401MDV2KE is ROHS3 Compliant. Both share identical ECCN and HTSUS classifications.

Q: What is the electrical life expectancy for these switches?

A: Both the 7401MDV2KE and 7401MDV2PE are rated for 100,000 electrical cycles, providing equivalent operational longevity across switching applications.

Q: Are these components suitable for high-temperature applications?

A: Both switches operate across the -30°C to 85°C temperature range. Applications requiring operation outside this range require alternative component selection.
