APEM 5637MAB Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The APEM 5637MAB is an active production toggle switch featuring SPDT (Single Pole Double Throw) circuitry with momentary-off-momentary (Mom-Off-Mom) switching function. This panel-mount component is rated for 6A at 125V AC and 4A at 30V DC, designed for applications requiring reliable electromechanical switching with sealed terminals. Substitute parts are identified to provide functional equivalence when the primary part is unavailable or when design requirements permit alternative manufacturers meeting equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APEM 5637MAB is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be Mom-Off-Mom
• Current rating must meet or exceed application requirements (minimum 6A AC or 4A DC)
• Voltage rating must meet or exceed application requirements (minimum 125V AC or 30V DC)

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount
• Termination style must be Solder Lug
• Panel cutout diameter must accommodate the component (12.50mm reference)
• Bushing thread must be 15/32-32 for panel installation

Environmental & Compliance Requirements:

• Operating temperature range must encompass application environment
• RoHS3 compliance required for regulated markets
• Electrical life rating should support application duty cycle

The C&K 7105TZQE meets the core substitution criteria with equivalent SPDT Mom-Off-Mom functionality, panel-mount configuration, and solder lug termination. Electrical ratings are within acceptable parameters for most applications, with minor deviations noted in the comparison table below.

Engineering Selection Recommendations

Primary Part (APEM 5637MAB): Select the APEM 5637MAB for applications requiring maximum electrical ratings (6A AC at 125V), extended operating temperature range (-40°C minimum), or higher electrical life expectancy (50,000 cycles). This part is active in production with established supply chain availability.

Substitute Part (C&K 7105TZQE): The C&K 7105TZQE is suitable as a substitute when application requirements are within its electrical specifications: maximum 5A AC at 120V, maximum 5A DC at 28V, operating temperature minimum -30°C, and electrical life up to 40,000 cycles. Both parts maintain ROHS3 compliance and identical circuit functionality. Panel cutout diameter difference (11.91mm vs 12.50mm) requires verification against panel hole tolerance specifications.

Both parts are active production items with ROHS3 compliance and REACH documentation available. Selection between primary and substitute should be based on specific application electrical requirements and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7105TZQE replace the APEM 5637MAB in all applications?

A: No. The C&K substitute is suitable only for applications where current requirements do not exceed 5A AC (APEM rated 6A) and voltage does not exceed 120V AC (APEM rated 125V). Verify your application's actual current and voltage requirements before substitution.

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

A: The APEM 5637MAB requires a 12.50mm circular cutout, while the C&K 7105TZQE requires 11.91mm. If your panel is already drilled for 12.50mm, the C&K part may not fit securely. Verify panel hole dimensions and tolerance specifications before substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both the APEM 5637MAB and C&K 7105TZQE are ROHS3 compliant and suitable for regulated markets requiring RoHS certification.

Q: What is the difference in electrical life between these parts?

A: The APEM 5637MAB is rated for 50,000 electrical cycles, while the C&K 7105TZQE is rated for 40,000 cycles. For applications with high switching frequency or long service life requirements, the APEM part provides higher cycle endurance.

Q: Do both parts have identical switch function?

A: Yes. Both parts feature SPDT (Single Pole Double Throw) circuitry with Mom-Off-Mom (momentary-off-momentary) switching function, ensuring identical operational behavior in circuit applications.

Q: What is the operating temperature consideration for substitution?

A: The APEM 5637MAB operates from -40°C to 85°C, while the C&K 7105TZQE operates from -30°C to 85°C. If your application requires operation below -30°C, the APEM part is required.
