C&K 7103TCWCLE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7103TCWCLE is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component features an On-Off-On switch function with IP67 ingress protection and epoxy-sealed terminals. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations.

Substitute Part Grouping Explanation

Substitute parts for the 7103TCWCLE are categorized based on electrical and mechanical compatibility within the allowed parameters for SPDT toggle switches:

Direct Equivalent (Same Manufacturer):

• 7103TCWCRE: Identical electrical specifications and mechanical form factor. Differs only in product status (Active vs. Obsolete) and RoHS/REACH compliance status.

Similar Substitutes (Cross-Manufacturer):

• 34ASP38T7M2QT (Grayhill Inc.): Matches core electrical parameters (5A, 125V AC, 28V DC), mechanical mounting (Panel Mount, PC Pin termination, 11.91mm circular cutout, 15/32-32 bushing thread), and operational characteristics (On-Off-On function, -30°C to 85°C, 40,000 cycles). AC voltage rating is 125V versus 120V, within acceptable tolerance for AC applications.
• 34ASP37T7M2RT (Grayhill Inc.): Shares mechanical compatibility (Panel Mount, PC Pin, 11.91mm cutout, 15/32-32 bushing) and operational temperature range. Electrical ratings differ significantly (0.4VA at 20V), limiting substitution to lower-power applications only.

Substitution logic is based on matching: circuit configuration (SPDT), switch function (On-Off-On), mounting type (Panel Mount), termination style (PC Pin), panel cutout dimensions, bushing thread specification, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The 7103TCWCRE is the primary substitute for the obsolete 7103TCWCLE. Both parts share identical electrical and mechanical specifications. The 7103TCWCRE is currently in active production status with improved compliance: ROHS3 compliant and REACH affected (versus non-compliant and REACH unaffected for the original). This part is suitable for all applications previously using the 7103TCWCLE.

For Cross-Manufacturer Substitution: The 34ASP38T7M2QT (Grayhill Inc.) provides full electrical and mechanical compatibility for applications requiring 5A at 120-125V AC with 28V DC capability. The 125V AC rating exceeds the original 120V specification and is acceptable for standard AC line voltage applications. This part is active production status with RoHS compliance.

The 34ASP37T7M2RT (Grayhill Inc.) is limited to low-power applications due to its 0.4VA rating at 20V maximum. This part is suitable only for circuits operating below 20V and 0.4VA and should not be used as a general substitute for the main part.

Compliance Considerations: All active substitute parts (7103TCWCRE and 34ASP38T7M2QT) meet current RoHS requirements. For applications subject to REACH regulations, the 7103TCWCRE is REACH affected, while the 34ASP38T7M2QT is REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can the 7103TCWCRE be used as a direct replacement for the 7103TCWCLE? A: Yes. The 7103TCWCRE is electrically and mechanically identical to the 7103TCWCLE. The primary differences are product status (Active vs. Obsolete) and improved regulatory compliance (ROHS3 compliant and REACH affected). No circuit modifications are required.

Q: What is the difference between the C&K 7103TCWCRE and the Grayhill 34ASP38T7M2QT? A: Both parts share identical mechanical mounting specifications (Panel Mount, PC Pin termination, 11.91mm circular cutout, 15/32-32 bushing thread) and core electrical function (SPDT, On-Off-On, 5A, 40,000 cycle life). The Grayhill part has a 125V AC rating versus 120V AC for the C&K part. Both support 28V DC. The parts are from different manufacturers and may have different lead times and availability.

Q: Can the 34ASP37T7M2RT be used instead of the 7103TCWCLE? A: The 34ASP37T7M2RT shares mechanical compatibility but has significantly lower electrical ratings (0.4VA at 20V maximum). It is suitable only for low-power applications operating below 20V and 0.4VA. It cannot be used as a general substitute for the main part in applications requiring 5A at 120V.

Q: Are all substitute parts panel-mount compatible with the original? A: Yes. All listed substitute parts use identical panel cutout dimensions (Circular - 11.91mm Dia) and bushing thread specification (15/32-32), ensuring mechanical compatibility with existing panel installations.

Q: What is the operating temperature range for all substitute parts? A: All substitute parts operate across the same temperature range: -30°C to 85°C, matching the original 7103TCWCLE specification.

Q: Do the substitute parts have the same electrical life rating? A: Yes. All substitute parts are rated for 40,000 electrical cycles, identical to the original part.
