APEM 5646AB2 Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The APEM 5646AB2 is a panel-mount toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 6A AC at 125V and 4A DC at 30V. This switch is designed for On-On applications requiring reliable electrical switching in industrial and commercial control panels. The product maintains Active status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and circuit functionality align within acceptable operational parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APEM 5646AB2 is determined by the following critical parameters:

Circuit Compatibility: Both the main part and substitute must maintain DPDT configuration with On-On switching function to preserve circuit logic and control functionality.

Electrical Ratings: Substitute parts must meet or exceed the AC voltage and current requirements (125V AC, 6A AC minimum). DC ratings may vary within acceptable operational margins (30V DC, 4A DC baseline).

Mechanical Compatibility: Panel mount configuration, solder lug termination, and 1/4-40 bushing thread must be maintained. Panel cutout diameter tolerance of ±0.15mm is acceptable for standard panel drilling practices.

Environmental Compliance: RoHS3 compliance and unlimited MSL rating are mandatory for equivalent substitution in regulated applications.

Actuator Specifications: Standard round actuator type with actuator length within 0.26mm variance accommodates manufacturing tolerances and panel mounting clearances.

The E-Switch 100DP1T4B1M1QEH qualifies as a substitute based on matching DPDT circuit, On-On function, panel mount configuration, solder lug termination, and RoHS3 compliance. Electrical ratings remain within acceptable operational parameters for most industrial control applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Application: The APEM 5646AB2 remains the specified component for applications requiring 6A AC switching at 125V with extended low-temperature operation (-40°C) and maximum electrical life (50,000 cycles).

Substitute Application: The E-Switch 100DP1T4B1M1QEH is suitable for applications where AC current requirements do not exceed 5A at 120V, operating temperatures remain above -30°C, and electrical cycle life of 40,000 cycles is acceptable. Both components maintain Active product status and full RoHS3 compliance, ensuring regulatory compatibility in current manufacturing environments.

Compliance Consideration: Both parts carry identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications, supporting equivalent procurement and supply chain management.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T4B1M1QEH replace the APEM 5646AB2 in all applications?

A: No. The E-Switch substitute is rated for 5A AC at 120V, which is lower than the APEM specification of 6A AC at 125V. Substitution is valid only for applications operating within the E-Switch electrical ratings. Additionally, the minimum operating temperature is -30°C versus -40°C for the APEM part.

Q: What is the significance of the panel cutout diameter difference (6.50mm vs 6.35mm)?

A: The 0.15mm variance falls within standard panel drilling tolerances. Both parts use identical 1/4-40 bushing threads and will mount securely in panels drilled to either specification. Existing panel cutouts for the APEM 5646AB2 may require slight enlargement for the E-Switch substitute.

Q: Are there electrical life implications when substituting?

A: Yes. The APEM 5646AB2 is rated for 50,000 electrical cycles, while the E-Switch 100DP1T4B1M1QEH is rated for 40,000 cycles. For high-cycle applications, the APEM part provides extended service life. The E-Switch substitute is appropriate for moderate-cycle applications.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the APEM 5646AB2 and E-Switch 100DP1T4B1M1QEH are RoHS3 compliant, REACH unaffected, and carry EAR99 classification. Both maintain unlimited moisture sensitivity rating (MSL 1).

Q: What is the actuator length variance impact?

A: The 0.26mm difference (APEM 16.00mm vs E-Switch 16.26mm) is within manufacturing tolerance and does not affect panel mounting or operational clearance for standard control panel applications.
