C&K 7101SDAV2ME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101SDAV2ME is a panel-mount toggle switch with SPDT (Single Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The switch features a standard round actuator with vertical orientation, PC pin termination, and epoxy sealed terminals suitable for industrial control applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101SDAV2ME is determined by strict alignment with the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-On
• Mounting type: Panel Mount, Right Angle, Vertical
• Termination style: PC Pin
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Actuator type: Standard Round

Electrical Compatibility Criteria:

• Current rating must support minimum 5A (AC/DC)
• Voltage ratings must meet or exceed 120V AC and 28V DC
• Operating temperature range must encompass -30°C to 85°C

Compliance Criteria:

• RoHS compliance status
• REACH compliance status
• ECCN classification

Substitute parts are grouped into two categories:

Direct Manufacturer Substitute (C&K Series): Parts from the same manufacturer with identical mechanical and electrical specifications, differing only in product status or compliance variant.

Cross-Manufacturer Equivalents (Grayhill Inc., Electroswitch): Parts meeting all mechanical interface requirements and core electrical parameters, with documented compatibility for panel-mount applications using identical cutout and thread specifications.

Parameter Comparison

Engineering Selection Recommendations

7101SDAV2SE (C&K Direct Substitute): This part provides the closest functional equivalence to the 7101SDAV2ME, maintaining identical electrical ratings (5A at 120V AC / 28V DC), mechanical interface, and actuator dimensions. The primary distinction is active product status, enabling continued procurement and supply chain support. ROHS3 compliance is maintained. REACH status differs (REACH Affected vs. REACH Unaffected), requiring compliance verification for applications subject to REACH regulations.

34ASP11B1M7QT (Grayhill Inc.): This cross-manufacturer substitute meets the 5A current requirement and exceeds the AC voltage rating (125V vs. 120V). Mechanical interface compatibility is confirmed through identical panel cutout (6.35mm circular) and bushing thread (1/4-40) specifications. Actuator length differs (10.41mm vs. 12.45mm), which may affect panel aesthetics but does not impact functional compatibility. Electrical life is reduced to 40,000 cycles. ROHS3 compliance and REACH Unaffected status are maintained.

34ASP11B1M7RT and 34ASP11B3M7RT (Grayhill Inc.): These parts do not meet the primary electrical requirements. Current rating is reduced to 0.4VA and AC voltage rating is limited to 20V, both significantly below the 120V AC / 5A specification of the main part. These parts are suitable only for low-voltage, low-current applications and are not recommended as direct substitutes for the 7101SDAV2ME.

A123S1YAV2B (Electroswitch): This part does not meet the primary electrical requirements. Current rating is 0.5VA and AC voltage rating is 28V, both below the 120V AC / 5A specification. Panel cutout dimensions are not specified, creating uncertainty regarding mechanical interface compatibility. This part is not recommended as a direct substitute for the 7101SDAV2ME.

Frequently Asked Questions (FAQ)

Q: Can the 7101SDAV2SE be used as a direct replacement for the 7101SDAV2ME?

A: Yes. The 7101SDAV2SE maintains identical electrical ratings (5A at 120V AC / 28V DC), mechanical interface specifications, and actuator dimensions. The primary advantage is active product status, ensuring continued availability. REACH compliance status differs and should be verified for applications subject to REACH regulations.

Q: What are the key differences between the C&K 7101SDAV2SE and Grayhill 34ASP11B1M7QT?

A: Both parts support 5A current and meet or exceed 120V AC requirements. Mechanical interface compatibility is confirmed through identical panel cutout and bushing thread specifications. The Grayhill part has a shorter actuator (10.41mm vs. 12.45mm) and reduced electrical life (40,000 vs. 100,000 cycles). Manufacturer sourcing and supply chain considerations may influence selection.

Q: Why are the Grayhill 34ASP11B1M7RT and 34ASP11B3M7RT not suitable substitutes?

A: These parts have significantly reduced electrical ratings (0.4VA at 20V AC/DC) compared to the main part specification (5A at 120V AC / 28V DC). They are designed for low-voltage, low-current applications and cannot safely handle the electrical loads specified for the 7101SDAV2ME.

Q: Is the Electroswitch A123S1YAV2B compatible with the 7101SDAV2ME?

A: No. The A123S1YAV2B has insufficient electrical ratings (0.5VA at 28V AC/DC) for applications requiring 5A at 120V AC. Additionally, panel cutout dimensions are not specified, creating uncertainty regarding mechanical interface compatibility.

Q: What should be considered when selecting between available substitutes?

A: Selection should prioritize electrical rating compatibility (minimum 5A at 120V AC / 28V DC), confirmed mechanical interface specifications (6.35mm circular panel cutout, 1/4-40 bushing thread), and compliance requirements (RoHS and REACH status). Product availability, supply chain lead times, and cost considerations are secondary factors that should be evaluated after confirming technical compatibility.

Q: Does actuator length variation affect functional compatibility?

A: Actuator length differences do not impact electrical or mechanical interface compatibility. Variations between 10.41mm and 12.45mm may affect panel aesthetics and operator feel but do not prevent functional substitution. Panel design should accommodate the specific actuator length of the selected part.

Q: What is the significance of electrical life ratings?

A: Electrical life indicates the number of switching cycles a part can withstand before performance degradation. The main part is rated for 100,000 cycles. Substitutes with lower ratings (40,000 or 60,000 cycles) may require more frequent replacement in high-cycle applications. Application duty cycle should be evaluated against the electrical life specification of the selected substitute.
