C&K 7201SY9AME Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201SY9AME is a through-hole, right-angle mounted toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The switch features epoxy sealed terminals, brass chrome-plated actuator, and 100,000 cycle electrical life rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201SY9AME is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: DPDT
• Switch function: On-On
• Mounting type: Through Hole, Right Angle
• Termination style: PC Pin
• Actuator type: Standard Round
• Bushing thread: Unthreaded

Electrical Performance Criteria:

• Current rating: minimum 5A (AC/DC)
• Voltage rating - AC: minimum 120V
• Voltage rating - DC: minimum 28V

Physical Compatibility Criteria:

• Actuator length tolerance: within ±0.26mm of 10.67mm
• Panel cutout dimensions: compatible with unthreaded bushing design

Two substitute parts meet these criteria with varying degrees of direct equivalence and performance characteristics.

Engineering Selection Recommendations

7201SY9ASE (Direct Equivalent - Recommended)

The C&K 7201SY9ASE is the direct equivalent substitute for the 7201SY9AME. Both parts share identical electrical ratings (5A, 120V AC, 28V DC), mechanical configuration, actuator dimensions, and electrical life (100,000 cycles). The 7201SY9ASE is currently in active production status, ensuring long-term availability. The primary difference is packaging (bulk versus tray) and regulatory compliance: the 7201SY9ASE is RoHS compliant and REACH affected, whereas the main part is non-compliant. For new designs or procurement requiring regulatory compliance, the 7201SY9ASE is the preferred direct replacement.

A223S1Y9AQ (Similar Substitute - Alternative)

The Electroswitch A223S1Y9AQ provides functional substitution with enhanced electrical performance. It exceeds the main part specifications in current rating (6A versus 5A) and AC voltage rating (125V versus 120V), while maintaining identical DC voltage rating (28V) and mounting configuration. The actuator length differs by 0.26mm (10.41mm versus 10.67mm), which may require mechanical validation in space-constrained applications. The electrical life rating is lower (60,000 cycles versus 100,000 cycles). This part is RoHS compliant and suitable for applications where higher current capacity is beneficial. The A223S1Y9AQ is appropriate when the main part and direct equivalent are unavailable and the application can accommodate the reduced cycle life specification.

Frequently Asked Questions (FAQ)

Q: Can the 7201SY9ASE directly replace the 7201SY9AME without circuit modification?

A: Yes. The 7201SY9ASE is a direct equivalent with identical electrical ratings, circuit configuration, and mechanical mounting. No circuit modifications are required. The only consideration is regulatory compliance: if your application requires RoHS compliance, the 7201SY9ASE is the appropriate choice.

Q: What is the significance of the 0.26mm actuator length difference between the main part and the A223S1Y9AQ?

A: The actuator length difference (10.67mm versus 10.41mm) may affect panel clearance and mechanical fit in applications with tight dimensional tolerances. Verify that the reduced actuator length does not interfere with panel geometry or adjacent components before selection.

Q: Is the A223S1Y9AQ suitable for applications requiring 100,000 cycle electrical life?

A: No. The A223S1Y9AQ is rated for 60,000 cycles, which is 40% lower than the main part specification. Applications requiring 100,000 cycle life must use the 7201SY9AME or 7201SY9ASE.

Q: What packaging formats are available for these substitutes?

A: The 7201SY9AME is supplied in tray packaging. The 7201SY9ASE is supplied in bulk packaging. The A223S1Y9AQ is supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 7201SY9ASE and A223S1Y9AQ are RoHS compliant. The original 7201SY9AME is RoHS non-compliant. For applications subject to RoHS requirements, either substitute part is acceptable.

Q: What is the temperature operating range difference between the main part and substitutes?

A: The 7201SY9AME and 7201SY9ASE operate from -30°C to 85°C. The A223S1Y9AQ operates from -30°C to 90°C, providing 5°C additional high-temperature margin. For applications operating near 85°C, the A223S1Y9AQ offers extended thermal headroom.
