Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103P3CWWLE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Current and voltage ratings (5A AC/DC, 120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Flat Anti-Rotation, 11.43mm length)
• Termination style (Wire Wrap)
• Panel interface dimensions (Circular 6.35mm Dia, 1/4-40 bushing thread)
• Ingress protection rating (IP67)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 cycles)

The C&K 7103P3CWWRE qualifies as a direct substitute based on complete alignment with all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7103P3CWWRE is a direct functional equivalent to the 7103P3CWWLE. The primary distinction is product lifecycle status: the original part is obsolete while the substitute remains in active production. Both parts maintain identical electrical and mechanical specifications, ensuring seamless integration into existing designs.

The 7103P3CWWRE carries RoHS compliance certification and is REACH affected, compared to the 7103P3CWWLE which is RoHS3 compliant and REACH unaffected. Selection between these parts should be based on regulatory requirements applicable to the end application and geographic market.

Frequently Asked Questions (FAQ)

Q: Can the 7103P3CWWRE replace the 7103P3CWWLE in existing assemblies?

A: Yes. Both parts share identical electrical ratings (5A at 120V AC / 28V DC), circuit configuration (SPDT), mechanical mounting interface (Panel Mount, 6.35mm circular cutout, 1/4-40 bushing), actuator specifications (Flat Anti-Rotation, 11.43mm), and termination style (Wire Wrap). No design modifications are required.

Q: What is the difference between these two parts?

A: The parts differ in product status and compliance certifications. The 7103P3CWWLE is obsolete and RoHS3 compliant with REACH unaffected status. The 7103P3CWWRE is active production and RoHS compliant with REACH affected status. All functional and mechanical parameters are identical.

Q: Are there any compatibility concerns with panel cutout dimensions?

A: No. Both parts specify identical panel interface requirements: circular 6.35mm diameter cutout with 1/4-40 bushing thread. Existing panel mounting holes require no modification.

Q: What is the operating temperature range for these switches?

A: Both parts operate across -30°C to 85°C. This range applies to all electrical and mechanical functions.

Q: How many electrical cycles are rated for these switches?

A: Both parts are rated for 40,000 electrical cycles, defining the expected operational life under specified load conditions.
