E103MYCLE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The E103MYCLE is a panel-mount toggle switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) circuitry with On-Off-On switching function. Rated for 7.5A at 125V AC and 28V DC, this component is classified as obsolete. Due to its discontinued status, equivalent substitute parts from active product lines are necessary for new designs, repairs, and system upgrades requiring compatible SPDT toggle switch functionality with equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the E103MYCLE is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-Off-On
• Mounting type: Panel Mount
• Termination style: PC Pin
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Actuator material: Brass, Chrome Plated
• Operating temperature range: -30°C to 85°C (minimum)

Electrical Performance Criteria:

• Voltage rating - AC: 125V (minimum)
• Voltage rating - DC: 28V (minimum)
• Current rating: 7.5A (minimum for direct replacement)

Secondary Considerations:

• Ingress protection rating: IP57 or higher
• Electrical life: 40,000 cycles (minimum)
• RoHS and REACH compliance status

Substitute parts meeting all primary criteria with equal or superior electrical performance are classified as direct equivalents. Parts with reduced current ratings (5A-6A) are classified as similar substitutes suitable for applications not requiring the full 7.5A capacity.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred):

E103MYCRE (C&K) is the direct equivalent replacement for E103MYCLE. Both components share identical electrical ratings (7.5A at 125V AC/28V DC), mechanical dimensions, and mounting specifications. E103MYCRE is currently in active production status, ensuring long-term availability. The primary distinction is REACH compliance status; E103MYCRE is REACH Affected while E103MYCLE is REACH Unaffected. For applications subject to REACH regulations, this difference must be evaluated against regulatory requirements.

Similar Substitutes (Reduced Current Rating):

2M1-SP3-T1-B1-M2QE (Carling Technologies), 34BWSP32B1M2QT (Grayhill Inc.), A121M1DCQ (Electroswitch), and A121M1DCQP (Electroswitch) are suitable substitutes for applications where the full 7.5A current capacity is not required. These parts maintain SPDT configuration, On-Off-On function, and compatible mechanical mounting specifications. Current ratings range from 5A to 6A, representing 67-80% of the original specification. All substitute parts are in active production status with RoHS compliance.

Compliance Considerations:

All substitute parts maintain RoHS compliance. REACH status varies: Carling Technologies and Grayhill Inc. parts are REACH Unaffected; Electroswitch parts show Vendor Undefined status. For applications in REACH-regulated markets, verify vendor documentation before final selection.

Actuator Length Variation:

2M1-SP3-T1-B1-M2QE features a 10.40mm actuator length compared to the standard 5.08mm specification. This extended length may affect panel aesthetics and operator feel. A121M1DCQP incorporates an anti-rotation actuator design, providing enhanced mechanical stability compared to standard round actuators.

Frequently Asked Questions (FAQ)

Q: Can E103MYCRE be used as a direct drop-in replacement for E103MYCLE?

A: Yes. E103MYCRE maintains identical electrical ratings (7.5A at 125V AC/28V DC), circuit configuration (SPDT), switch function (On-Off-On), mounting type (Panel Mount), and mechanical dimensions (6.35mm circular cutout, 1/4-40 bushing thread). The components are mechanically and electrically interchangeable. REACH compliance status differs and must be evaluated for regulatory applicability.

Q: What is the significance of the reduced current ratings in substitute parts?

A: Substitute parts from Carling Technologies, Grayhill Inc., and Electroswitch are rated for 5A-6A current capacity compared to the E103MYCLE specification of 7.5A. These parts are suitable for applications where the actual circuit current does not exceed their rated capacity. Applications requiring the full 7.5A capacity must use E103MYCRE or equivalent 7.5A-rated components.

Q: Are all substitute parts compatible with the same panel cutout dimensions?

A: E103MYCRE, 2M1-SP3-T1-B1-M2QE, and 34BWSP32B1M2QT specify circular 6.35mm diameter panel cutouts with 1/4-40 bushing threads, matching the original E103MYCLE specification. A121M1DCQ and A121M1DCQP do not specify panel cutout dimensions; verify mechanical compatibility with your panel design before selection.

Q: What is the difference between A121M1DCQ and A121M1DCQP?

A: Both parts are manufactured by Electroswitch with identical electrical specifications (6A at 125V AC/28V DC) and operating temperature range (-30°C to 90°C). The primary difference is actuator type: A121M1DCQ features a standard round actuator, while A121M1DCQP incorporates an anti-rotation actuator design for enhanced mechanical stability.

Q: How do ingress protection ratings affect substitution?

A: E103MYCLE and E103MYCRE are rated IP57 (dust protected, waterproof). Carling Technologies and Grayhill Inc. substitute parts are rated IP67 (dust tight, waterproof), providing superior environmental protection. Electroswitch parts do not specify ingress protection ratings. For applications requiring sealed operation, IP67-rated parts provide enhanced protection.

Q: What is the impact of electrical life cycle differences?

A: E103MYCLE and E103MYCRE are rated for 40,000 electrical cycles. Substitute parts from Carling Technologies and Grayhill Inc. are rated for 50,000 cycles; Electroswitch parts are rated for 60,000 cycles. Higher cycle ratings indicate extended component life under repeated switching conditions. Applications with high switching frequency benefit from higher-rated components.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry RoHS compliance certification. E103MYCRE, 2M1-SP3-T1-B1-M2QE, and 34BWSP32B1M2QT are ROHS3 compliant. A121M1DCQ and A121M1DCQP are RoHS compliant. Verify specific RoHS version requirements for your application.

Q: What does "REACH Affected" status mean for E103MYCRE?

A: REACH Affected indicates the component may contain substances of concern regulated under the REACH directive. E103MYCRE carries this designation while E103MYCLE is REACH Unaffected. For applications in REACH-regulated markets (primarily EU), evaluate whether REACH Affected status creates compliance obligations or requires alternative sourcing.
