APEM 5644TH2RAB9 Toggle Switch SP3T Equivalent & Substitute Parts

Part Overview

The APEM 5644TH2RAB9 is an SP3T (single pole triple throw) toggle switch rated for 6A at 125V AC and 4A at 30V DC. This panel-mount switch features a momentary-on-momentary (Mom-On-Mom) function with a flatted brass nickel-plated actuator and solder lug termination. The part is currently active in production with 1030 units in stock and is ROHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified when alternative manufacturers offer SP3T toggle switches with compatible electrical ratings, mechanical mounting specifications, and functional characteristics that allow direct replacement in panel-mount applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APEM 5644TH2RAB9 is determined by the following critical parameters:

Circuit Configuration: SP3T topology is mandatory for functional equivalence.

Electrical Ratings: The substitute must support minimum 5A at 120V AC and 28V DC to accommodate the primary part's 6A @ 125V AC and 4A @ 30V DC specifications.

Switch Function: Mom-On-Mom operation must be maintained.

Mounting Specification: Panel mount with circular cutout diameter within 6.35mm to 6.50mm range ensures mechanical compatibility.

Termination: Solder lug termination is required for circuit board integration.

Compliance: ROHS3 compliance is necessary for regulatory alignment.

The C&K 7215P3YZQE qualifies as a substitute based on matching SP3T configuration, Mom-On-Mom function, panel-mount design, solder lug termination, and ROHS3 compliance. Electrical ratings of 5A @ 120V AC and 28V DC are within acceptable operating parameters for this application category.

Parameter Comparison

Engineering Selection Recommendations

Both the APEM 5644TH2RAB9 and C&K 7215P3YZQE are active production parts with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Selection between these parts should be based on application-specific requirements:

APEM 5644TH2RAB9 is the primary choice when maximum current capacity (6A AC) and extended operating temperature range (-40°C) are required, or when higher electrical life expectancy (50,000 cycles) is specified.

C&K 7215P3YZQE is suitable for applications where the 5A AC rating and -30°C minimum temperature are acceptable, and where the anti-rotation actuator feature provides mechanical advantage in the panel assembly.

Both parts meet the SP3T Mom-On-Mom functional requirement and panel-mount installation specification. Panel cutout diameter difference (6.50mm vs. 6.35mm) is within standard mechanical tolerance for circular apertures.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7215P3YZQE directly replace the APEM 5644TH2RAB9 in all applications?

A: Direct replacement is possible when the application current requirement does not exceed 5A AC and the minimum operating temperature does not fall below -30°C. Both parts share identical SP3T configuration, Mom-On-Mom function, and solder lug termination. Panel cutout diameter tolerance accommodates both 6.35mm and 6.50mm specifications.

Q: What is the significance of the panel cutout diameter difference?

A: The APEM part specifies 6.50mm circular cutout while the C&K part specifies 6.35mm. Standard panel drilling tolerances typically accommodate both dimensions. Verify panel aperture specifications before substitution if tight mechanical tolerances are specified.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant with MSL 1 (unlimited) rating. The C&K part is REACH Affected while the APEM part is REACH Unaffected. Confirm REACH compliance requirements for your specific application and supply chain.

Q: How do electrical life ratings affect part selection?

A: The APEM 5644TH2RAB9 provides 50,000 electrical cycles while the C&K 7215P3YZQE provides 40,000 cycles. Select based on application duty cycle and expected product lifetime requirements.

Q: What is the functional difference between flatted and flat anti-rotation actuators?

A: Both actuator types are flatted designs suitable for panel-mount toggle switches. The anti-rotation feature on the C&K part provides additional mechanical stability. Actuator length difference (11.40mm vs. 11.43mm) is negligible for standard panel applications.
