C&K 7101MDA3ME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101MDA3ME is a panel-mount toggle switch with SPDT (Single Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design and procurement requirements. The switch features epoxy-sealed terminals, a standard round actuator, and PC pin termination suitable for industrial control applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Direct Equivalent Criteria:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Mounting type (Panel Mount, Right Angle)
• Termination style (PC Pin)
• Bushing thread specification (1/4-40)
• Current and voltage ratings (minimum 5A AC, 120V AC, 28V DC)

Substitute Classification:

The C&K 7101MDA3SE qualifies as a direct equivalent, sharing identical electrical specifications, mounting geometry, and termination characteristics while maintaining active product status.

The Electroswitch A123M1DAQ and A123M1YAG are classified as similar substitutes. These parts maintain SPDT configuration, On-On function, PC pin termination, and 1/4-40 bushing thread compatibility. However, they feature higher current ratings (6A), elevated voltage ratings (125V AC), and different actuator geometry (5.08mm vs. 6.86mm), requiring mechanical validation for panel cutout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: C&K 7101MDA3SE

The 7101MDA3SE is the recommended direct replacement for the obsolete 7101MDA3ME. Both parts share identical electrical ratings, mechanical dimensions, and termination specifications. The 7101MDA3SE maintains active product status and RoHS compliance, ensuring long-term supply chain availability and regulatory alignment.

Alternative Selection: Electroswitch A123M1DAQ or A123M1YAG

The Electroswitch parts provide functional substitution with enhanced electrical performance. Both A123M1DAQ and A123M1YAG offer higher current capacity (6A vs. 5A) and voltage ratings (125V AC vs. 120V AC), providing design margin for applications operating near rated limits. These parts maintain identical DC voltage ratings (28V), SPDT configuration, and PC pin termination.

Mechanical compatibility requires validation: the Electroswitch actuator length (5.08mm) differs from the C&K specification (6.86mm), necessitating panel cutout geometry assessment. The Electroswitch parts do not specify panel cutout dimensions, requiring dimensional confirmation before implementation.

Both Electroswitch parts demonstrate reduced electrical life (60,000 cycles vs. 100,000 cycles), applicable to applications with lower cycle frequency requirements. All substitute options maintain RoHS compliance and epoxy-sealed terminal construction.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7101MDA3SE directly replace the 7101MDA3ME without design modification?

A: Yes. The 7101MDA3SE maintains identical electrical specifications (5A, 120V AC, 28V DC), mounting configuration (panel mount, right angle), termination style (PC pin), and bushing thread (1/4-40). No circuit or mechanical redesign is required.

Q: What are the key differences between the C&K 7101MDA3SE and Electroswitch A123M1DAQ/A123M1YAG?

A: The Electroswitch parts provide higher current (6A vs. 5A) and AC voltage ratings (125V vs. 120V). The actuator length differs (5.08mm vs. 6.86mm), requiring mechanical validation for panel cutout compatibility. Electroswitch parts specify lower electrical life (60,000 vs. 100,000 cycles).

Q: Are the Electroswitch A123M1DAQ and A123M1YAG electrically interchangeable?

A: Yes. Both parts share identical electrical specifications, circuit configuration, and termination characteristics. Selection between them depends on packaging requirements and inventory availability.

Q: What compliance certifications apply to all substitute options?

A: All parts maintain RoHS compliance. The 7101MDA3ME is ROHS3 compliant; the 7101MDA3SE and Electroswitch parts are RoHS compliant. All parts carry EAR99 ECCN classification and HTSUS code 8536.50.9065.

Q: Can Electroswitch parts be used in applications requiring 100,000-cycle electrical life?

A: No. Electroswitch A123M1DAQ and A123M1YAG are rated for 60,000 cycles. Applications requiring 100,000-cycle life must use C&K 7101MDA3SE.

Q: What mechanical validation is required before substituting Electroswitch parts?

A: Panel cutout geometry must be confirmed. The Electroswitch actuator length (5.08mm) differs from C&K specification (6.86mm). Electroswitch parts do not specify panel cutout dimensions; dimensional drawings must be obtained from the manufacturer to ensure mechanical fit.
