C&K 7103SYAV2ME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7103SYAV2ME is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component features panel mount installation with right-angle vertical orientation and PC pin termination. The part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7103SYAV2ME are identified based on matching electrical and mechanical parameters. The primary substitution criteria are:

• Circuit configuration (SPDT)
• Mounting type (Panel Mount, Right Angle, Vertical)
• Termination style (PC Pin)
• Bushing thread specification (1/4-40)
• Actuator material and length compatibility
• Operating temperature range overlap
• Current and voltage rating compatibility within application requirements

Two substitute categories are identified: a direct C&K equivalent with active product status, and cross-manufacturer alternatives from Electroswitch that maintain functional compatibility within specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7103SYAV2SE represents the primary substitute for the obsolete 7103SYAV2ME. This part maintains identical electrical ratings (5A at 120V AC / 28V DC), mechanical configuration, and termination specifications while offering active product status and current RoHS compliance. The 7103SYAV2SE is the recommended choice for direct replacement in existing designs.

The Electroswitch A121S1YAV2Q provides an alternative cross-manufacturer option with equivalent AC voltage rating (125V) and superior current capacity (6A), suitable for applications requiring higher current margins. The A121S1YAV2B is limited to 0.5VA and is appropriate only for low-power applications.

All three substitute parts maintain the required panel mount configuration, 1/4-40 bushing thread, and PC pin termination. Selection should be based on specific application current requirements and voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can the 7103SYAV2SE directly replace the 7103SYAV2ME?

A: Yes. The 7103SYAV2SE maintains identical electrical ratings (5A, 120V AC, 28V DC), mechanical mounting configuration, panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and PC pin termination. The primary difference is active product status versus obsolete classification.

Q: What are the key differences between the C&K and Electroswitch alternatives?

A: The C&K 7103SYAV2SE is a direct equivalent. The Electroswitch A121S1YAV2Q offers higher current capacity (6A versus 5A) and extended operating temperature range (-30°C to 90°C versus -30°C to 85°C). The A121S1YAV2B is rated for only 0.5VA and is unsuitable for the original application's 5A requirement.

Q: Are there mechanical compatibility concerns with cross-manufacturer substitution?

A: All substitute parts share identical mounting type (panel mount, right angle, vertical), bushing thread (1/4-40), and termination style (PC Pin). Minor differences in actuator length (10.67mm versus 10.41mm) are within typical mechanical tolerance for panel-mounted toggle switches.

Q: What compliance certifications apply to substitute parts?

A: All substitute parts are RoHS compliant. The 7103SYAV2SE carries RoHS Compliant status with REACH Affected designation. The Electroswitch alternatives carry RoHS Compliant status with Vendor Undefined REACH status.

Q: Which substitute is recommended for new designs?

A: The C&K 7103SYAV2SE is recommended for new designs requiring direct electrical and mechanical equivalence. The Electroswitch A121S1YAV2Q may be selected if higher current capacity or extended temperature range provides design margin benefits.
