7105TCWCLE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The 7105TCWCLE is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. Manufactured by C&K in the 7000 series, this switch features a momentary-off-momentary (Mom-Off-Mom) function with IP67 ingress protection and epoxy-sealed terminals. The part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7105TCWCLE are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Mounting type (Panel Mount)
• Actuator type and length (Standard Round, 17.45mm)
• Termination style (PC Pin)
• Bushing thread specification (15/32-32)
• Current and voltage ratings (minimum 5A AC, 120V AC, 28V DC)
• Operating temperature range (-30°C minimum, 85°C maximum)

Substitutes are grouped into two categories: direct equivalents from the same manufacturer with identical electrical specifications, and similar parts from alternative manufacturers that meet or exceed the electrical and mechanical requirements while maintaining functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

7105TCWCRE (Direct Equivalent): This C&K part is the primary substitute for the obsolete 7105TCWCLE. It maintains identical electrical specifications, mechanical dimensions, and functional characteristics. The 7105TCWCRE is currently in active production status with ROHS3 compliance certification. Selection of this part eliminates obsolescence risk while preserving all design parameters of the original circuit.

A127T1TCG (Similar Alternative): The Electroswitch A127T1TCG provides functional substitution with enhanced electrical ratings (6A current, 125V AC) and extended electrical life (60,000 cycles versus 40,000 cycles). This part meets all minimum requirements of the 7105TCWCLE while offering improved performance margins. The A127T1TCG is active in production and RoHS compliant. Panel cutout dimensions are not specified for this part; mechanical fit verification is required before implementation.

Frequently Asked Questions (FAQ)

Q: Can the 7105TCWCRE be used as a direct replacement for the 7105TCWCLE?

A: Yes. The 7105TCWCRE is electrically and mechanically identical to the 7105TCWCLE. Both parts share the same circuit configuration, current and voltage ratings, actuator dimensions, termination style, and bushing thread specification. The primary difference is product status: the 7105TCWCRE is active in production while the 7105TCWCLE is obsolete.

Q: What are the key differences between the 7105TCWCRE and A127T1TCG?

A: Both parts are SPDT Mom-Off-Mom switches with identical actuator dimensions and bushing threads. The A127T1TCG provides higher current capacity (6A versus 5A), higher AC voltage rating (125V versus 120V), and extended electrical life (60,000 versus 40,000 cycles). The A127T1TCG does not specify panel cutout dimensions, requiring mechanical verification for panel compatibility.

Q: Are all substitute parts panel-mount compatible?

A: All listed substitutes are panel-mount switches with matching actuator lengths (17.45mm) and bushing threads (15/32-32). The 7105TCWCRE specifies identical panel cutout dimensions (Circular - 11.91mm Dia) as the main part. The A127T1TCG does not specify panel cutout dimensions; physical verification is necessary to confirm panel fit.

Q: What compliance certifications apply to these parts?

A: The 7105TCWCLE and 7105TCWCRE are ROHS3 compliant. The A127T1TCG is RoHS compliant. All three parts are classified as EAR99 for export control purposes. The 7105TCWCLE and 7105TCWCRE are REACH unaffected or affected respectively; the A127T1TCG has undefined REACH status from the vendor.

Q: Can the A127T1TCG be used in applications requiring IP67 ingress protection?

A: The 7105TCWCLE and 7105TCWCRE both specify IP67 ingress protection. The A127T1TCG does not specify an ingress protection rating. If IP67 protection is a design requirement, the 7105TCWCRE is the appropriate selection.
