C&K 7203SDAV2ME Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7203SDAV2ME is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This component features a standard round actuator with PC pin termination and epoxy sealed terminals for enhanced durability. The part is currently obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for direct replacement in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7203SDAV2ME are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

• Circuit configuration (DPDT)
• Switch function (On-Off-On)
• Current rating (5A AC/DC minimum)
• Voltage ratings (120V AC, 28V DC minimum)
• Mounting type (Panel Mount, Right Angle, Vertical)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular 6.35mm Dia)
• Bushing thread (1/4-40)
• Operating temperature range (-30°C to 85°C)

Two substitute parts meet these criteria: the C&K 7203SDAV2SE (direct manufacturer equivalent with improved compliance status) and the Grayhill 34ADP31B1M7QT (functionally equivalent alternative from different manufacturer).

Parameter Comparison

Engineering Selection Recommendations

The C&K 7203SDAV2SE is the primary direct substitute for the obsolete 7203SDAV2ME. Both parts share identical electrical ratings, mechanical dimensions, and mounting specifications. The 7203SDAV2SE maintains active product status and achieves RoHS compliance, making it suitable for new designs and legacy system replacements where regulatory compliance is required.

The Grayhill 34ADP31B1M7QT provides a functionally equivalent alternative from a different manufacturer. This part meets all electrical and mechanical substitution criteria with AC voltage rating of 125V (exceeding the 120V requirement) and ROHS3 compliance. The actuator length differs at 10.41mm compared to 12.45mm in the C&K variants; this dimensional difference must be evaluated against specific panel mounting constraints in the application.

Selection between the two substitutes depends on supply chain availability, cost considerations, and regulatory requirements specific to the end application. Both parts maintain compatibility with the original 6.35mm panel cutout and 1/4-40 bushing thread specifications.

Frequently Asked Questions (FAQ)

Q: Can the 7203SDAV2SE directly replace the obsolete 7203SDAV2ME without modification?

A: Yes. The 7203SDAV2SE is a direct C&K manufacturer equivalent with identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (DPDT), actuator length (12.45mm), and mechanical mounting specifications (6.35mm panel cutout, 1/4-40 bushing thread). No panel modifications are required.

Q: What is the key difference between the 7203SDAV2SE and 34ADP31B1M7QT?

A: The primary difference is manufacturer (C&K versus Grayhill) and actuator length (12.45mm versus 10.41mm). Both maintain identical electrical specifications and panel cutout dimensions. The shorter actuator on the Grayhill part may affect tactile feel and visual appearance in the panel assembly.

Q: Are there compliance differences between the substitute parts?

A: Yes. The 7203SDAV2SE achieves RoHS compliance with REACH affected status. The 34ADP31B1M7QT achieves ROHS3 compliance with REACH unaffected status. The original 7203SDAV2ME is RoHS non-compliant. Selection should align with regulatory requirements of the target application and region.

Q: Will the 34ADP31B1M7QT work in applications rated for 120V AC?

A: Yes. The 34ADP31B1M7QT is rated for 125V AC, which exceeds the 120V AC requirement of the original part. The higher voltage rating provides compatibility with the original specification.

Q: Are there any mechanical considerations when substituting the Grayhill part?

A: The Grayhill 34ADP31B1M7QT has an actuator length of 10.41mm compared to 12.45mm for the C&K parts. This 2.04mm difference may affect panel aesthetics and operator feel. Verify that the shorter actuator does not create clearance issues or undesired tactile characteristics in the specific panel assembly.

Q: What is the electrical life expectancy for these substitute parts?

A: All three parts (7203SDAV2ME, 7203SDAV2SE, and 34ADP31B1M7QT) are rated for 40,000 electrical cycles, providing equivalent operational longevity.
