Equivalent & Substitute Parts for C&K 7103MPYCQE Toggle Switch SPDT

Part Overview

The C&K 7103MPYCQE is an active production toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This panel-mount switch features an anti-rotation brass actuator with epoxy sealed terminals and is designed for on-off-on switching applications. Alternative models may be required due to inventory constraints, application-specific voltage requirements, or packaging preferences while maintaining core switching functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for toggle switches is determined by mechanical and electrical compatibility within defined parameter ranges. The E-Switch 100SP3T1B1M2REH qualifies as a substitute based on the following alignment criteria:

Mechanical Compatibility:

• Panel cutout dimensions: Both use circular 6.35mm diameter openings
• Bushing thread: Both use 1/4-40 threading
• Mounting type: Both are panel-mount configurations
• Termination style: Both use PC pin termination
• Actuator material: Both feature brass, chrome-plated construction

Electrical Compatibility:

• Circuit configuration: Both are SPDT
• Switch function: Both are on-off-on
• Operating temperature: Both operate across -30°C to 85°C
• Electrical life: Both rated for 40,000 cycles
• Epoxy sealed terminals: Both feature this protection

Regulatory Compliance:

• RoHS3 compliance: Both meet this requirement
• ECCN classification: Both are EAR99
• HTSUS code: Both share 8536.50.9065

Voltage and Current Differences: The substitute operates at reduced voltage and current ratings (0.4VA at 20V AC/DC versus 5A at 120V AC/28V DC). This represents a downgrade in electrical capacity and is suitable only for applications with lower power requirements than the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active production status and meet ROHS3 compliance requirements. The C&K 7103MPYCQE is the primary specification for applications requiring 5A switching capacity at 120V AC or 28V DC with anti-rotation actuator design. The E-Switch 100SP3T1B1M2REH is suitable only for low-power applications with maximum requirements of 0.4VA at 20V AC/DC. Selection between these parts must be based on actual circuit voltage and current demands. The longer actuator length (10.41mm versus 5.08mm) and standard round actuator type of the substitute may affect panel ergonomics and mechanical fit. Packaging format differs (bulk versus tray), which may impact procurement and inventory management workflows.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP3T1B1M2REH directly replace the C&K 7103MPYCQE in all applications?

A: No. The substitute is rated for 0.4VA at 20V maximum, while the original is rated for 5A at 120V AC or 28V DC. Substitution is valid only for applications with lower voltage and current requirements that fall within the E-Switch specifications.

Q: Are the panel mounting dimensions identical?

A: Yes. Both switches use a circular 6.35mm diameter panel cutout with 1/4-40 bushing thread, ensuring mechanical compatibility for panel installation.

Q: What is the difference between the actuator types?

A: The C&K 7103MPYCQE features an anti-rotation actuator (5.08mm length), while the E-Switch 100SP3T1B1M2REH uses a standard round actuator (10.41mm length). The anti-rotation design prevents unintended rotation, while the standard round design allows free rotation. The longer actuator of the substitute may require different panel cutout positioning considerations.

Q: Do both switches have the same electrical life rating?

A: Yes. Both are rated for 40,000 electrical cycles, providing equivalent durability in switching operations.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and carry EAR99 ECCN classification. The C&K part is REACH Affected, while the E-Switch part is REACH Unaffected. Regulatory requirements for your application will determine which compliance status is necessary.

Q: What packaging formats are available?

A: The C&K 7103MPYCQE is supplied in bulk packaging, while the E-Switch 100SP3T1B1M2REH is supplied in tray packaging. Packaging selection may affect procurement quantities and inventory handling procedures.
