C&K 7101SYAV2ME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101SYAV2ME is a panel-mount toggle switch with SPDT (Single Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. This component features a standard round actuator with 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 7101SYAV2ME are identified based on strict parameter matching across electrical and mechanical specifications. The primary substitution criteria are:

Electrical Parameters: Circuit configuration (SPDT), switch function (On-On), current rating, voltage ratings (AC and DC), and termination style (PC Pin).

Mechanical Parameters: Mounting type (Panel Mount, Right Angle, Vertical), actuator type (Standard Round), panel cutout dimensions (Circular - 6.35mm Dia), and bushing thread (1/4-40).

Compliance Parameters: RoHS status and product status (active vs. obsolete).

Two substitute categories are identified:

Direct Equivalent: C&K 7101SYAV2SE maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance.

Similar Alternatives: Electroswitch A123S1YAV2Q and A123S1YAV2B provide SPDT configuration with panel-mount vertical orientation and PC pin termination, though with variations in current and voltage ratings, actuator length, and electrical life.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The C&K 7101SYAV2SE is the primary substitute for the 7101SYAV2ME. Both parts share identical electrical ratings (5A at 120V AC / 28V DC), mechanical configuration (panel mount, vertical orientation, 1/4-40 bushing thread), and actuator specifications. The 7101SYAV2SE is active in production and RoHS compliant, addressing the obsolescence status of the original part while maintaining full electrical and mechanical compatibility.

For Alternative Applications: The Electroswitch A123S1YAV2Q provides higher current capacity (6A) and slightly elevated AC voltage rating (125V) with extended operating temperature range (-30°C to 90°C). This part is suitable for applications requiring increased current headroom. The A123S1YAV2B operates at reduced current (0.5VA) and lower voltage (28V AC/DC), appropriate only for low-power applications. Both Electroswitch alternatives feature reduced electrical life (60,000 cycles versus 100,000 cycles) and unspecified panel cutout dimensions.

Compliance Considerations: Applications subject to RoHS requirements must use either the C&K 7101SYAV2SE or Electroswitch alternatives, as the original 7101SYAV2ME is non-compliant. The C&K 7101SYAV2SE is REACH Affected, while Electroswitch parts show Vendor Undefined REACH status.

Frequently Asked Questions (FAQ)

Q: Can the 7101SYAV2SE directly replace the 7101SYAV2ME without circuit modification?

A: Yes. The 7101SYAV2SE maintains identical electrical ratings (5A at 120V AC / 28V DC), circuit configuration (SPDT On-On), and mechanical specifications (panel mount, vertical orientation, 1/4-40 bushing thread, PC pin termination). No circuit or mechanical redesign is required.

Q: What are the key differences between the C&K 7101SYAV2SE and Electroswitch alternatives?

A: The C&K 7101SYAV2SE matches the original part's electrical life (100,000 cycles) and operating temperature range (-30°C to 85°C). Electroswitch parts offer reduced electrical life (60,000 cycles) and extended temperature range (-30°C to 90°C). Current and voltage ratings vary: A123S1YAV2Q provides 6A at 125V AC, while A123S1YAV2B operates at 0.5VA at 28V AC/DC.

Q: Are panel cutout dimensions critical for substitution?

A: Yes. The original 7101SYAV2ME specifies a circular 6.35mm diameter cutout with 1/4-40 bushing thread. The C&K 7101SYAV2SE maintains these specifications. Electroswitch alternatives do not specify panel cutout dimensions; mechanical verification is required before installation.

Q: Which substitute is appropriate for RoHS-compliant applications?

A: Both the C&K 7101SYAV2SE and Electroswitch A123S1YAV2Q and A123S1YAV2B are RoHS compliant. The original 7101SYAV2ME is non-compliant and cannot be used in RoHS-regulated applications.

Q: How does electrical life affect part selection?

A: The original 7101SYAV2ME and C&K 7101SYAV2SE are rated for 100,000 cycles. Electroswitch alternatives are rated for 60,000 cycles. Applications requiring extended operational life or frequent switching should prioritize the C&K 7101SYAV2SE.

Q: What is the impact of actuator length variation?

A: The original part and C&K 7101SYAV2SE feature 10.67mm actuator length. Electroswitch alternatives have 10.41mm actuators. This 0.26mm difference may affect panel aesthetics and operator feel but does not impact electrical function. Mechanical clearance verification is recommended for space-constrained installations.
