APEM 5644MTHAB Toggle Switch SP3T Equivalent & Substitute Parts

Part Overview

The APEM 5644MTHAB is an SP3T (single pole, three throw) toggle switch rated for 6A at 125V AC and 4A at 30V DC. This panel-mount switch features a standard round actuator with solder lug termination and is designed for applications requiring three-position switching with on-on-on functionality. The part is currently active in production with 956 units in stock. Equivalent and substitute parts are identified when electrical ratings, mechanical form factor, and circuit configuration align within acceptable operational parameters.

Key Parameters

Substitute Part Grouping Explanation

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

• Circuit configuration must be SP3T with on-on-on switching function
• Current rating must meet or exceed 6A AC and 4A DC requirements
• Voltage rating must support minimum 125V AC and 30V DC operation
• Mounting type must be panel mount with compatible panel cutout dimensions
• Actuator type and length must be standard round with similar dimensions (±0.5mm tolerance acceptable)
• Termination style must be solder lug
• Bushing thread must be 15/32-32 for mechanical compatibility
• Operating temperature range must encompass -40°C to 85°C minimum
• RoHS3 compliance required for regulatory alignment

The C&K 7211TZQE meets the core substitution criteria with equivalent circuit configuration, compatible mechanical form factor, and overlapping electrical specifications within acceptable operational limits.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7211TZQE functions as an equivalent substitute for the APEM 5644MTHAB in applications where the following conditions are met:

• Operating voltage does not exceed 120V AC or 28V DC
• Operating current does not exceed 5A AC
• Minimum operating temperature remains above -30°C
• Panel cutout diameter tolerance accommodates 11.91mm specification
• Application cycle life requirement does not exceed 40,000 cycles

Both parts maintain ROHS3 compliance and identical circuit configuration. The APEM 5644MTHAB provides higher current and voltage ratings, extended temperature range, and longer electrical life. The C&K 7211TZQE is suitable for applications with less demanding electrical and thermal specifications.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7211TZQE replace the APEM 5644MTHAB in all applications?

A: No. The C&K part has lower AC current rating (5A vs 6A), lower voltage ratings (120V AC vs 125V AC, 28V DC vs 30V DC), narrower operating temperature range (-30°C to 85°C vs -40°C to 85°C), and reduced electrical life (40,000 vs 50,000 cycles). Substitution is valid only when application requirements fall within C&K specifications.

Q: What is the panel cutout diameter difference between these parts?

A: The APEM 5644MTHAB requires a 12.50mm diameter cutout, while the C&K 7211TZQE requires 11.91mm. This 0.59mm difference may require panel modification or use of adapter bushings depending on panel thickness and tolerance specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the APEM 5644MTHAB and C&K 7211TZQE are ROHS3 compliant.

Q: What is the actuator length difference?

A: The APEM actuator is 17.50mm and the C&K actuator is 17.45mm, a difference of 0.05mm. This is negligible for most panel-mount applications.

Q: Which part should be selected for low-temperature applications below -30°C?

A: The APEM 5644MTHAB is rated to -40°C and is the appropriate choice for applications requiring operation below -30°C. The C&K 7211TZQE minimum operating temperature is -30°C.

Q: Do both parts use the same termination method?

A: Yes. Both parts use solder lug termination and are compatible with identical PCB footprints.
