C&K 7101TCME Toggle Switch SPDT 5A 120V Equivalent & Substitute Parts

Part Overview

The C&K 7101TCME 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 PC pin termination and epoxy sealed terminals for enhanced durability. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where this functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101TCME is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (minimum 5A AC/DC)
• Voltage rating (minimum 120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator type and length (Standard Round, 17.45mm)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 11.91mm Dia)
• Bushing thread (15/32-32)

Direct Equivalent: The C&K 7101TCSE represents a direct equivalent from the same manufacturer and series, maintaining identical electrical and mechanical specifications while offering active product status.

Similar Substitutes: The Grayhill 34ASP18T7M2QT and Electroswitch A123T1TCG/A123T1TCQ variants meet the core functional requirements with the following considerations: they maintain SPDT configuration, On-On function, 5A-6A current capability, and compatible mechanical interfaces. Voltage ratings and electrical life specifications differ within acceptable operational parameters for equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The C&K 7101TCSE is the primary recommendation as a direct substitute. It maintains identical electrical and mechanical specifications while offering active product status and improved availability. Both parts are RoHS compliant and share the same series lineage, ensuring compatibility with existing designs without modification.

For Alternative Sourcing: The Grayhill 34ASP18T7M2QT and Electroswitch A123T1TCG/A123T1TCQ variants are suitable alternatives where the 7101TCSE is unavailable. These parts meet functional requirements with the following considerations:

• Voltage ratings (125V AC) exceed the 120V AC requirement of the original specification
• Current ratings (5A-6A) meet or exceed the 5A requirement
• Electrical life ratings (40,000-60,000 cycles) are lower than the original 100,000 cycles
• All alternatives maintain RoHS compliance and compatible mechanical interfaces

Selection should prioritize product status (active vs. obsolete) and compliance certifications when availability permits.

Frequently Asked Questions (FAQ)

Q: Can the 7101TCSE be used as a direct replacement for the 7101TCME?

A: Yes. The 7101TCSE is a direct equivalent with identical electrical ratings (5A, 120V AC, 28V DC), mechanical configuration (panel mount, 17.45mm actuator, 15/32-32 bushing thread), and termination style (PC pin). The primary difference is product status: the 7101TCSE is active while the 7101TCME is obsolete.

Q: What are the key differences between the C&K 7101TCSE and the Grayhill 34ASP18T7M2QT?

A: Both maintain SPDT configuration and On-On function with compatible mechanical interfaces. The Grayhill part has a higher AC voltage rating (125V vs. 120V) and higher current rating (5A vs. 5A), but lower electrical life (40,000 cycles vs. 100,000 cycles). The C&K part is from the same manufacturer as the original, providing closer design continuity.

Q: Are the Electroswitch A123T1TCG and A123T1TCQ interchangeable?

A: Yes. Both parts are functionally identical with 6A current rating, 125V AC voltage rating, 60,000 cycle electrical life, and identical mechanical specifications. Selection between them can be based on availability and packaging preferences.

Q: Do all substitute parts fit the same panel cutout?

A: The C&K 7101TCSE and Grayhill 34ASP18T7M2QT both specify circular 11.91mm diameter panel cutouts, matching the original 7101TCME. The Electroswitch variants do not specify panel cutout dimensions; mechanical verification is required before installation.

Q: What compliance certifications apply to these substitute parts?

A: All substitute parts are RoHS compliant. The 7101TCSE is RoHS compliant (vs. RoHS3 for the original). The Grayhill and Electroswitch parts are RoHS compliant. REACH status varies: the 7101TCSE is REACH Affected, while the Grayhill part is REACH Unaffected and Electroswitch parts are Vendor Undefined.

Q: Can these switches be used in DC applications?

A: Yes. All parts are rated for 28V DC operation, supporting both AC and DC circuit applications within their specified current and voltage limits.
