Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7103SPCWCBE and TE Connectivity 1-1825137-5 are active-status products with ROHS3 compliance and REACH affected status. Selection between these parts should be based on the following considerations:

C&K 7103SPCWCBE is the primary specification. It provides 40,000 electrical cycles and features an anti-rotation actuator with chrome-plated brass construction.

TE Connectivity 1-1825137-5 is a functional equivalent meeting all critical electrical and mechanical parameters. It provides 6,000 electrical cycles and features a standard round actuator with nickel-plated brass construction. This part is suitable for applications where the lower cycle rating is acceptable and where the standard actuator geometry is compatible with the mechanical design.

Both parts satisfy ROHS3 compliance requirements and are suitable for applications requiring IP67 ingress protection with epoxy sealed terminals.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical electrical ratings (0.4VA, 20V AC/DC), circuit configuration (SPDT), switch function (On-Off-On), mounting specifications (panel mount with 1/4-40 bushing thread), and panel cutout dimensions (6.35mm circular). Both operate across -30°C to 85°C and feature PC pin termination with epoxy sealed terminals.

Q: What are the differences between these two parts?

A: The primary differences are electrical life rating (C&K: 40,000 cycles vs. TE Connectivity: 6,000 cycles), actuator type (C&K: anti-rotation vs. TE Connectivity: standard round), actuator length (C&K: 10.67mm vs. TE Connectivity: 10.41mm), and actuator material finish (C&K: chrome plated vs. TE Connectivity: nickel plated).

Q: Are both parts ROHS3 compliant?

A: Yes. Both the C&K 7103SPCWCBE and TE Connectivity 1-1825137-5 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Does the difference in electrical life affect substitution eligibility?

A: Electrical life is a performance characteristic that does not affect mechanical or electrical compatibility. Selection should be based on application cycle requirements. The C&K part is suitable for higher-cycle applications, while the TE Connectivity part is suitable for lower-cycle applications.

Q: Are the panel mounting dimensions identical?

A: Yes. Both parts feature a circular 6.35mm diameter panel cutout and 1/4-40 bushing thread, ensuring identical panel mounting compatibility.
