C&K 7201MD9AV2LE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201MD9AV2LE is a toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. This component features a through-hole, right-angle vertical mounting design with a standard round actuator and epoxy sealed terminals. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for continued system support and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201MD9AV2LE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Through Hole, Right Angle, Vertical)
• Actuator specifications (Standard Round, 6.86mm length)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life (100,000 cycles)
• Base product number (7201MD)

The C&K 7201MD series maintains consistent electrical and mechanical interfaces across variants. Substitute parts must match all specified parameters to ensure direct functional replacement without circuit redesign or mechanical modification.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7201MD9AV2RE is the direct functional equivalent to the obsolete 7201MD9AV2LE. Both components share identical electrical ratings, mechanical dimensions, and circuit configurations. The primary distinction is product status and regulatory compliance.

The 7201MD9AV2RE is currently in active production status, ensuring availability for new designs and replacement inventory. This part carries RoHS Compliant certification and REACH Affected status, meeting current environmental and regulatory requirements for commercial and industrial applications. The 7201MD9AV2LE, while RoHS non-compliant and REACH Unaffected, is obsolete and no longer manufactured.

For new production, system redesigns, or long-term inventory planning, the 7201MD9AV2RE is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, the 7201MD9AV2LE remains functionally equivalent if existing stock is available.

Frequently Asked Questions (FAQ)

Q: Can the 7201MD9AV2RE directly replace the 7201MD9AV2LE without circuit modification?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including voltage ratings, current capacity, mounting configuration, and actuator dimensions. Direct substitution is possible without circuit redesign.

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

A: The primary differences are product status and regulatory compliance. The 7201MD9AV2LE is obsolete and RoHS non-compliant. The 7201MD9AV2RE is active production and RoHS Compliant. All functional specifications are identical.

Q: Why should I use the 7201MD9AV2RE instead of the 7201MD9AV2LE?

A: The 7201MD9AV2RE is in active production, ensuring reliable availability. It meets current RoHS environmental standards. The 7201MD9AV2LE is obsolete and may face supply constraints.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. Both components feature identical through-hole, right-angle vertical mounting, standard round actuators of 6.86mm length, and PC pin termination. Panel cutout dimensions and bushing specifications are equivalent.

Q: What electrical parameters must match for substitution eligibility?

A: Critical parameters include DPDT circuit configuration, On-On switch function, 5A current rating (AC/DC), 120V AC voltage rating, 28V DC voltage rating, and 100,000 cycle electrical life. Both parts meet these specifications.
