7201SPD9AV2ME Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The 7201SPD9AV2ME is a toggle switch with DPDT (Double Pole Double Throw) configuration manufactured by C&K, rated for 5A at 120V AC and 28V DC. This component features through-hole, right-angle vertical mounting with PC pin termination and epoxy sealed terminals. The part is currently obsolete, necessitating identification of functionally equivalent alternatives from active product lines that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: DPDT
• Switch function: On-On
• Mounting type: Through Hole, Right Angle, Vertical
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C minimum

Electrical Compatibility Criteria:

• Current rating: Equal to or greater than 5A (AC/DC)
• Voltage rating - AC: Equal to or greater than 120V
• Voltage rating - DC: Equal to or greater than 28V

Mechanical Compatibility Criteria:

• Actuator length tolerance: ±0.25mm from 12.45mm nominal
• Bushing thread: Unthreaded

Substitute parts are grouped into two categories based on electrical parameter alignment:

Category A - Full Electrical Equivalents (5A @ 120V AC / 28V DC): Parts meeting or exceeding all primary electrical specifications with active product status.

Category B - Reduced Electrical Rating Substitutes (0.4VA @ 20V AC/DC): Parts with lower current and voltage ratings suitable only for applications operating within their specified electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 7201SPD9AV2SE (C&K)

The 7201SPD9AV2SE is the direct successor within the C&K 7000 series. It maintains identical electrical ratings (5A @ 120V AC / 28V DC), mechanical configuration, and actuator specifications as the obsolete 7201SPD9AV2ME. This part is active in production with RoHS compliance and REACH affected status, making it the preferred direct replacement for new designs and obsolete part substitution.

Secondary Recommendation: 100AWDP1T1B4M7QE (E-Switch)

The 100AWDP1T1B4M7QE meets all primary electrical requirements (5A @ 120V AC / 28V DC) and maintains through-hole, right-angle vertical mounting with PC pin termination. This part offers enhanced ingress protection (IP67) and ROHS3 compliance. The actuator length is 12.70mm, representing a 0.25mm increase from the original specification. This part is suitable for applications requiring higher environmental protection.

Tertiary Recommendation: A223S1D9AV2Q (Electroswitch)

The A223S1D9AV2Q exceeds the primary electrical specifications with 6A current rating at 125V AC and maintains 28V DC compatibility. Operating temperature range extends to 90°C. The actuator length is 10.41mm, representing a 2.04mm reduction from the original. This part is suitable for applications with higher current or voltage margins and extended temperature operation.

Limited Substitution: 100DP1T1B2M7RE (E-Switch) and 34ADP11B4M7RT (Grayhill)

These parts feature reduced electrical ratings (0.4VA @ 20V AC/DC) and are suitable only for applications operating within their specified electrical envelope. They are not direct replacements for the original 5A @ 120V specification but may serve as substitutes in low-power switching applications.

Frequently Asked Questions (FAQ)

Q: Can 7201SPD9AV2SE directly replace 7201SPD9AV2ME in existing designs?

A: Yes. The 7201SPD9AV2SE maintains identical electrical ratings, mechanical mounting configuration, and actuator specifications. It is the active production equivalent within the same manufacturer series.

Q: What is the significance of the actuator length difference in 100AWDP1T1B4M7QE?

A: The 100AWDP1T1B4M7QE has an actuator length of 12.70mm compared to the original 12.45mm. This 0.25mm difference may affect panel cutout clearance and operator feel. Panel geometry must be evaluated before substitution.

Q: Why do 100DP1T1B2M7RE and 34ADP11B4M7RT have lower electrical ratings?

A: These parts are designed for low-power signal switching applications. Their 0.4VA rating at 20V AC/DC limits them to applications with significantly lower power requirements than the original 5A @ 120V specification. They are not suitable for general-purpose replacement.

Q: What compliance differences exist between substitute options?

A: The original 7201SPD9AV2ME is RoHS non-compliant. All active substitutes (7201SPD9AV2SE, 100AWDP1T1B4M7QE, A223S1D9AV2Q, 100DP1T1B2M7RE, 34ADP11B4M7RT) are RoHS compliant or ROHS3 compliant, meeting current environmental regulations.

Q: Are there mechanical compatibility concerns with different actuator types?

A: The original part features an anti-rotation actuator, while most substitutes use standard round actuators. This difference affects operator feel and prevents accidental rotation. Panel design and application requirements must be evaluated to determine if this difference is acceptable.

Q: What is the impact of different electrical life ratings?

A: The original part is rated for 100,000 cycles. Substitutes range from 30,000 to 100,000 cycles. Applications requiring high cycle counts should prioritize 7201SPD9AV2SE (100,000 cycles) or A223S1D9AV2Q (60,000 cycles) over lower-rated alternatives.

Q: Can A223S1D9AV2Q be used in applications requiring exactly 5A @ 120V?

A: Yes. The A223S1D9AV2Q is rated for 6A @ 125V AC, which exceeds the original 5A @ 120V requirement. It provides additional current and voltage margin and is suitable for this application.
