C&K 7201MD9AGE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201MD9AGE is an active production toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. This through-hole, right-angle mounted switch features epoxy sealed terminals and is designed for applications requiring reliable electromechanical switching. Substitute parts may be required due to inventory constraints, lead time considerations, or specific packaging requirements while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201MD9AGE is determined by strict alignment with the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Mounting type must be Through Hole, Right Angle
• Termination style must be PC Pin
• Operating temperature range must encompass -30°C to 85°C
• RoHS3 compliance required

Electrical Performance Criteria:

• Current rating must be equal to or greater than 5A (AC/DC)
• Voltage rating - AC must be equal to or greater than 120V
• Voltage rating - DC must be equal to or greater than 28V

The E-Switch 100DP1T2B4M6QE meets all primary and electrical criteria. The E-Switch 100DP1T2B4M6RE does not qualify as a direct substitute due to insufficient current rating (0.4VA) and voltage ratings (20V AC/DC), which fall below the 7201MD9AGE specifications.

Parameter Comparison

Engineering Selection Recommendations

Qualified Substitute: E-Switch 100DP1T2B4M6QE is the only qualified substitute for the C&K 7201MD9AGE. Both parts are active production items with ROHS3 compliance. The 100DP1T2B4M6QE meets or exceeds all electrical specifications (5A at 120V AC / 28V DC) and maintains identical circuit configuration, switch function, mounting type, and termination style. The primary design consideration is the reduced actuator length (5.08mm versus 6.86mm), which must be evaluated against panel cutout and mechanical assembly requirements. Electrical life differs (40,000 cycles versus 100,000 cycles), which should be assessed against application duty cycle expectations.

Non-Qualified Alternative: E-Switch 100DP1T2B4M6RE does not qualify as a substitute due to electrical ratings insufficient for the 7201MD9AGE application. The 0.4VA current rating and 20V maximum voltage ratings are below the required 5A and 120V AC specifications.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T2B4M6QE be used as a direct replacement for the C&K 7201MD9AGE? A: The 100DP1T2B4M6QE meets all critical electrical and mechanical specifications for substitution. However, the reduced actuator length (5.08mm versus 6.86mm) requires verification against your specific panel cutout and mechanical assembly design.

Q: What is the significance of the different actuator lengths? A: Actuator length affects the physical engagement depth with the switch panel. The 7201MD9AGE has a 6.86mm actuator, while the 100DP1T2B4M6QE has a 5.08mm actuator. This difference must be evaluated to ensure proper mechanical fit and operation within your application's panel thickness and mounting configuration.

Q: Why is the E-Switch 100DP1T2B4M6RE not suitable as a substitute? A: The 100DP1T2B4M6RE has a maximum current rating of 0.4VA and voltage ratings of 20V AC/DC, both significantly below the 7201MD9AGE requirements of 5A and 120V AC / 28V DC. Using this part in an application designed for the 7201MD9AGE would result in component failure or unsafe operation.

Q: Does the difference in electrical life (100,000 versus 40,000 cycles) affect substitution suitability? A: Electrical life indicates the number of switching cycles the component can withstand. The 7201MD9AGE is rated for 100,000 cycles while the 100DP1T2B4M6QE is rated for 40,000 cycles. For applications with high switching frequency or long operational life requirements, this difference should be factored into component selection and maintenance planning.

Q: Are there packaging differences between the main part and substitute? A: Yes. The C&K 7201MD9AGE is supplied in Tray packaging, while the E-Switch 100DP1T2B4M6QE is supplied in Bulk packaging. Packaging differences may affect inventory management, handling procedures, and component protection during storage and transport.

Q: Are both parts RoHS compliant? A: Yes. Both the C&K 7201MD9AGE and E-Switch 100DP1T2B4M6QE are ROHS3 compliant, meeting environmental and regulatory requirements for restricted substance use.
