Equivalent & Substitute Parts for C&K 7201SY9AV2ME Toggle Switch

Part Overview

The C&K 7201SY9AV2ME is a DPDT toggle switch rated for 5A at 120V AC and 28V DC, designed for through-hole, right-angle vertical mounting applications. This part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The switch features epoxy-sealed terminals, brass chrome-plated actuators, and a 100,000-cycle electrical life rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201SY9AV2ME is determined by the following critical parameters:

• Circuit configuration (DPDT required)
• Switch function (On-On operation)
• Current rating (minimum 5A AC/DC)
• Voltage ratings (minimum 120V AC, 28V DC)
• Mounting type (Through Hole, Right Angle, Vertical)
• Actuator type and length compatibility
• Termination style (PC Pin)
• Operating temperature range coverage

Two substitute categories are identified: direct manufacturer alternatives from C&K and functionally equivalent parts from alternative manufacturers that meet or exceed the electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

7201SY9AV2SE (C&K Direct Substitute): This part is the primary equivalent for the obsolete 7201SY9AV2ME. It maintains identical electrical ratings, mechanical dimensions, and mounting configuration while offering active product status and RoHS compliance. The 7201SY9AV2SE is suitable for direct replacement in existing designs and new applications requiring C&K component continuity.

A223S1D9AV2Q (Electroswitch Alternative): This part provides functional equivalence with enhanced current rating (6A versus 5A) and extended operating temperature range (-30°C to 90°C). The actuator length is 0.26mm shorter (10.41mm versus 10.67mm), which may require mechanical validation in space-constrained applications. Electrical life is rated at 60,000 cycles compared to 100,000 cycles for the original part. This substitute is suitable for applications where higher current capacity and extended temperature operation are beneficial, provided mechanical fit is confirmed.

Frequently Asked Questions (FAQ)

Q: Can the 7201SY9AV2SE be used as a direct drop-in replacement for the 7201SY9AV2ME?

A: Yes. The 7201SY9AV2SE maintains identical electrical specifications (5A, 120V AC, 28V DC), circuit configuration (DPDT), mounting type (Through Hole, Right Angle, Vertical), and actuator dimensions (10.67mm). It is a direct functional equivalent suitable for replacement without design modification.

Q: What are the key differences between the 7201SY9AV2SE and A223S1D9AV2Q?

A: The primary differences are manufacturer (C&K versus Electroswitch), current rating (5A versus 6A), voltage rating AC (120V versus 125V), actuator length (10.67mm versus 10.41mm), operating temperature range (-30°C to 85°C versus -30°C to 90°C), and electrical life (100,000 versus 60,000 cycles). Both maintain DPDT configuration and PC Pin termination.

Q: Is the A223S1D9AV2Q suitable for applications requiring 100,000 electrical cycles?

A: The A223S1D9AV2Q is rated for 60,000 electrical cycles. Applications requiring 100,000-cycle performance should use the 7201SY9AV2SE or original 7201SY9AV2ME specification.

Q: Does the 0.26mm difference in actuator length between substitutes affect mechanical compatibility?

A: Actuator length differences may impact panel cutout alignment and actuator engagement in space-constrained designs. Mechanical validation is required when substituting the A223S1D9AV2Q (10.41mm) for the original 7201SY9AV2ME (10.67mm).

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 7201SY9AV2SE and A223S1D9AV2Q are RoHS compliant, whereas the original 7201SY9AV2ME is RoHS non-compliant.
