7103SPYCQE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The 7103SPYCQE is an active production toggle switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) circuitry with On-Off-On switching function. This panel-mount component is rated for 5A at 120V AC and 28V DC, with anti-rotation actuator design and epoxy-sealed PC pin termination. The part is ROHS3 compliant and maintains 40,000 electrical life cycles. Substitute parts are identified when equivalent electrical ratings, mechanical mounting specifications, and circuit configurations are maintained across the allowed parameter set.

Key Parameters

Substitute Part Grouping Explanation

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

• Circuit configuration must be SPDT
• Switch function must be On-Off-On
• Current rating must be 5A (AC/DC)
• Voltage ratings must be 120V AC and 28V DC minimum
• Mounting type must be Panel Mount
• Panel cutout dimensions must be Circular - 6.35mm Dia
• Bushing thread must be 1/4-40
• Termination style must be PC Pin
• Operating temperature range must encompass -30°C ~ 85°C
• Product status must be Active

The 100SP3T1B1M2QEH manufactured by E-Switch meets all substitution criteria. Variations in actuator type (Anti-Rotation versus Standard Round) and actuator length (10.67mm versus 10.41mm) remain within acceptable mechanical tolerances for panel-mount applications with identical cutout and bushing specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 7103SPYCQE and 100SP3T1B1M2QEH are active production components with ROHS3 compliance and equivalent electrical specifications. Selection between these parts is based on:

• Availability: 100SP3T1B1M2QEH has 976 units in stock versus 691 units for 7103SPYCQE
• Regulatory status: 7103SPYCQE is REACH Affected; 100SP3T1B1M2QEH is REACH Unaffected
• Actuator design: Anti-Rotation actuator (7103SPYCQE) versus Standard Round actuator (100SP3T1B1M2QEH)

Both parts satisfy identical electrical and mechanical requirements for panel-mount SPDT toggle switch applications operating within the specified voltage, current, and temperature parameters.

Frequently Asked Questions (FAQ)

Q: Can the 100SP3T1B1M2QEH replace the 7103SPYCQE in existing designs?

A: Yes. Both parts share identical circuit configuration (SPDT), electrical ratings (5A at 120V AC / 28V DC), panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and PC pin termination. The actuator type and length differences do not affect electrical or mechanical compatibility for standard panel-mount applications.

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

A: The 7103SPYCQE features an anti-rotation actuator, while the 100SP3T1B1M2QEH uses a standard round actuator. Both designs accommodate the identical 6.35mm circular panel cutout and 1/4-40 bushing thread. Actuator type selection depends on application-specific mechanical requirements not specified in the electrical parameter set.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and rated for identical operating temperatures (-30°C ~ 85°C). The 7103SPYCQE is REACH Affected while the 100SP3T1B1M2QEH is REACH Unaffected. Applications subject to REACH regulations should specify the E-Switch part.

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

A: Yes. Both the 7103SPYCQE and 100SP3T1B1M2QEH are rated for 40,000 electrical life cycles.

Q: What packaging is available for these parts?

A: Both parts are supplied in Bulk packaging.
