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

Part Overview

The C&K 7103SHCBE is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This switch operates in an On-Off-On function with a standard round actuator and PC pin termination. The part is currently active in production with 784 units in stock.

Finding equivalent and substitute parts becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements necessitate alternative sourcing options. The parts listed below maintain functional compatibility based on shared electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7103SHCBE are identified based on strict parameter matching across electrical and mechanical specifications. The substitution logic is as follows:

Primary Substitution Criteria (Must Match):

• Circuit configuration: SPDT
• Switch function: On-Off-On
• Mounting type: Panel Mount
• Termination style: PC Pin
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Operating temperature range: -30°C to 85°C

Electrical Compatibility Parameters:

• Current rating and voltage ratings must support the application requirements
• RoHS3 compliance status

Mechanical Compatibility Parameters:

• Actuator type: Standard Round
• Illumination status: Non-Illuminated

The following parts meet these criteria and are listed as direct substitutes.

Engineering Selection Recommendations

TE Connectivity 1-1825137-5 (Gemini A Series)

This part is an active production component with identical electrical ratings (0.4VA at 20V AC/DC) and matching mechanical specifications. The panel cutout dimensions, bushing thread, and termination style are identical to the 7103SHCBE. Both parts are ROHS3 compliant and REACH affected. The primary difference is the reduced electrical life rating (6,000 cycles versus 40,000 cycles) and slightly shorter actuator length (10.41mm versus 10.67mm). This substitute is suitable for applications where the lower cycle rating is acceptable and inventory availability is a priority.

NKK M2013SS1W03 (M Series)

This part has an obsolete product status and should not be selected for new designs or long-term production applications. While it maintains the same circuit configuration, switch function, mounting type, and mechanical interface, it has significantly higher electrical ratings (6A AC, 3A DC at 125V AC, 30V DC). The panel cutout diameter is 6.50mm, requiring a slightly larger opening than the 7103SHCBE. The electrical life is 25,000 cycles. REACH status is unaffected, whereas the primary part is REACH affected. This part is listed for reference only and is not recommended for substitution in new applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1825137-5 be used as a direct replacement for the C&K 7103SHCBE?

A: Yes, for applications operating at or below 0.4VA and 20V AC/DC. Both parts share identical electrical ratings, circuit configuration, mounting type, panel cutout dimensions, bushing thread, and termination style. The actuator length difference (10.41mm versus 10.67mm) is within typical mechanical tolerance for panel-mount switches. Verify that the reduced electrical life rating (6,000 cycles) meets your application requirements.

Q: Why is the NKK M2013SS1W03 listed as obsolete?

A: The product status field indicates this part is no longer in active production. Obsolete parts should not be selected for new designs or applications requiring long-term supply assurance.

Q: What is the significance of the panel cutout dimension difference in the NKK part?

A: The NKK M2013SS1W03 requires a 6.50mm circular cutout, compared to 6.35mm for the C&K 7103SHCBE. This 0.15mm difference may require panel modification and is a mechanical incompatibility factor.

Q: Are all listed parts RoHS3 compliant?

A: Yes, all three parts listed carry ROHS3 compliance certification.

Q: What does REACH Affected versus REACH Unaffected mean for substitution?

A: REACH Affected indicates the part is subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. The C&K and TE Connectivity parts are REACH Affected, while the NKK part is REACH Unaffected. Regulatory requirements in your application region determine whether this distinction is relevant to your selection.

Q: Which substitute has the best electrical life rating?

A: The C&K 7103SHCBE has the highest electrical life at 40,000 cycles, followed by the NKK M2013SS1W03 at 25,000 cycles, and the TE Connectivity 1-1825137-5 at 6,000 cycles.
