Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103P3CWCKE is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: C&K
• Series: 7000
• Circuit Configuration: SPDT
• Switch Function: On-Off-On
• Current Rating: 0.4VA (AC/DC)
• Voltage Rating: 20V (AC and DC)
• Mounting Type: Panel Mount
• Actuator Type: Flat Anti-Rotation
• Actuator Length: 11.43mm
• Panel Cutout Dimensions: Circular 6.35mm Dia
• Bushing Thread: 1/4-40
• Termination Style: PC Pin
• Ingress Protection: IP67
• Operating Temperature Range: -30°C to 85°C
• Electrical Life: 40,000 Cycles

The C&K 7103P3CWCPE meets all mandatory matching parameters and qualifies as a direct substitute. The primary distinction is product status: the 7103P3CWCKE is obsolete, while the 7103P3CWCPE is active production.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7103P3CWCPE is the direct substitute for the obsolete 7103P3CWCKE. Both components share identical electrical specifications, mechanical dimensions, and environmental ratings. The 7103P3CWCPE is currently in active production, ensuring availability and supply chain continuity.

Compliance considerations: The 7103P3CWCPE carries RoHS compliance designation and is REACH Affected, whereas the 7103P3CWCKE is ROHS3 Compliant and REACH Unaffected. Both components share the same ECCN classification (EAR99) and HTSUS code (8536.50.9065). Selection between these parts should account for regulatory requirements specific to the end application and target market.
