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

Part Overview

The C&K 7103SCWCBE is an active-status toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This panel-mount switch features an On-Off-On function with PC pin termination and IP67 ingress protection. Finding equivalent substitute parts is necessary when managing component availability, optimizing procurement timelines, or addressing supply chain constraints while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103SCWCBE is determined by strict alignment of the following critical parameters:

• Circuit configuration: SPDT only
• Switch function: On-Off-On operation
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V (AC and DC)
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular 6.35mm diameter
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C minimum
• RoHS and REACH compliance status

The TE Connectivity ALCOSWITCH 1-1825137-5 meets all mandatory electrical and mechanical parameters required for direct substitution with the 7103SCWCBE.

Parameter Comparison

Engineering Selection Recommendations

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

• Availability and procurement lead time
• Inventory levels at authorized distributors
• Cost considerations within approved component specifications
• Actuator length tolerance: The TE Connectivity part features a 10.41mm actuator length compared to the C&K 10.67mm length. This 0.26mm difference is within typical mechanical tolerances for panel-mount toggle switches and does not affect functional compatibility.
• Electrical life rating: The C&K part specifies 40,000 cycles while the TE Connectivity part specifies 6,000 cycles. Application duty cycle requirements should inform part selection.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1825137-5 directly replace the C&K 7103SCWCBE in existing designs?

A: Yes. Both parts share identical electrical ratings (0.4VA, 20V AC/DC), circuit configuration (SPDT), switch function (On-Off-On), panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and PC pin termination. Operating temperature ranges and compliance certifications are equivalent.

Q: What is the significance of the actuator length difference?

A: The actuator length difference of 0.26mm (C&K 10.67mm versus TE Connectivity 10.41mm) falls within standard mechanical tolerances for panel-mount toggle switches. This variation does not affect electrical performance or mechanical fit in standard panel cutouts.

Q: Are there differences in electrical life between these parts?

A: Yes. The C&K 7103SCWCBE is rated for 40,000 electrical cycles, while the TE Connectivity 1-1825137-5 is rated for 6,000 cycles. Applications requiring extended cycle life should prioritize the C&K part. For low-cycle-count applications, both parts are suitable.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and REACH affected, with identical moisture sensitivity levels (MSL 1 - Unlimited). Both carry the same ECCN (EAR99) and HTSUS classification.

Q: What is the difference in ingress protection ratings?

A: The C&K 7103SCWCBE specifies IP67 (dust tight, waterproof). The TE Connectivity 1-1825137-5 does not specify an ingress protection rating in the provided data. Applications requiring IP67 protection should confirm TE Connectivity part specifications with the manufacturer.
