C&K 7105TCWZBES Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7105TCWZBES is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This component features momentary-off-momentary (Mom-Off-Mom) switching function with satin chrome actuator finish and IP67 ingress protection. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system maintenance and new design implementations where this functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7105TCWZBES is determined by strict alignment across the following critical parameters:

Electrical Parameters: Circuit configuration (SPDT), switch function (Mom-Off-Mom), current rating (0.4VA AC/DC), and voltage rating (20V AC/DC) must match exactly.

Mechanical Parameters: Panel mount configuration, panel cutout dimensions (11.91mm circular), bushing thread specification (15/32-32), actuator type (standard round), and actuator length (17.45mm) must be identical to ensure direct mechanical and electrical compatibility.

Environmental & Operational Parameters: Operating temperature range (-30°C to 85°C) and electrical life (40,000 cycles) establish the performance envelope for acceptable substitutes.

Termination & Interface: Solder lug termination style must be maintained for circuit board integration compatibility.

Two substitute parts meet these criteria: the C&K 7105TCWZBE (same manufacturer, active product status) and the Grayhill Inc. 34ASP48T7M1RT (alternative manufacturer, active product status).

Parameter Comparison

Engineering Selection Recommendations

C&K 7105TCWZBE: This substitute is the preferred option for direct replacement applications. It is manufactured by the same original equipment manufacturer (C&K) and maintains active product status, ensuring ongoing availability and supply chain continuity. The part carries identical electrical and mechanical specifications with ROHS3 compliance. The primary distinction is packaging format (bulk versus original) and terminal treatment (epoxy sealed versus satin chrome actuator finish), neither of which affects functional compatibility in the specified application envelope.

Grayhill Inc. 34ASP48T7M1RT: This substitute provides cross-manufacturer compatibility for applications where C&K component sourcing is constrained. The part meets all critical electrical and mechanical parameters with ROHS3 compliance and active product status. The 34ASP48T7M1RT does not specify ingress protection rating in the provided data, whereas the main part and C&K substitute both specify IP67. This difference should be evaluated against application environmental requirements. REACH compliance status differs (unaffected versus affected), which may influence supply chain considerations in regulated markets.

Frequently Asked Questions (FAQ)

Q: Can the 7105TCWZBE be used as a direct replacement for the 7105TCWZBES?

A: Yes. Both parts share identical electrical ratings (0.4VA, 20V AC/DC, SPDT Mom-Off-Mom), mechanical dimensions (11.91mm panel cutout, 15/32-32 bushing thread, 17.45mm actuator length), operating temperature range (-30°C to 85°C), and electrical life (40,000 cycles). The parts differ only in packaging format and terminal treatment, neither of which affects circuit functionality or panel integration.

Q: What is the key difference between the C&K 7105TCWZBE and the Grayhill 34ASP48T7M1RT?

A: Both parts are electrically and mechanically equivalent. The primary engineering consideration is that the Grayhill part does not specify an ingress protection rating, while the C&K parts both specify IP67 (dust tight, waterproof). For applications requiring sealed environmental protection, the C&K 7105TCWZBE is the specified choice. For general panel-mount applications without environmental sealing requirements, the Grayhill 34ASP48T7M1RT provides equivalent functionality.

Q: Are there any compliance differences between the substitute parts?

A: Both substitutes are ROHS3 compliant. The C&K 7105TCWZBE is REACH affected, while the Grayhill 34ASP48T7M1RT is REACH unaffected. For applications subject to REACH regulations, the C&K substitute maintains regulatory alignment with the original part. Both parts carry EAR99 ECCN classification.

Q: Why is the original 7105TCWZBES listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by C&K. The C&K 7105TCWZBE (active status) serves as the direct replacement, maintaining the same electrical and mechanical specifications while ensuring ongoing supply availability.

Q: Can I use either substitute interchangeably in my application?

A: Electrical and mechanical interchangeability is confirmed for both substitutes. Selection between them depends on supply chain factors, environmental protection requirements (IP67 specification), and regulatory compliance needs (REACH status). For new designs or applications with environmental sealing requirements, the C&K 7105TCWZBE is the recommended choice.
