Honeywell 13AT2-E Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The Honeywell 13AT2-E is a panel-mount toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 5A at 250V AC and 30V DC. This switch features a locking lever actuator with 30mm length and solder lug termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance and repair applications where original stock is depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 13AT2-E is determined by the following critical parameters:

Electrical Compatibility:

• Circuit configuration (DPDT)
• Switch function (On-Off-On)
• Current rating (5A minimum)
• Voltage ratings (AC and DC)

Mechanical Compatibility:

• Mounting type (Panel Mount)
• Actuator type (Locking Lever)
• Panel cutout dimensions (Circular - 12.40mm Dia)
• Bushing thread (15/32-32)
• Termination style compatibility

Regulatory Compliance:

• RoHS compliance status
• ECCN and HTSUS classifications

The substitute part 12TW1-1A shares the same circuit configuration (DPDT), switch function (On-Off-On), current rating (5A), mounting type (Panel Mount), actuator type (Locking Lever), panel cutout dimensions, and bushing thread specifications. However, the AC voltage rating differs (125V vs. 250V), and the termination style varies (Solder Turret vs. Solder Lug).

Parameter Comparison

Engineering Selection Recommendations

13AT2-E (Original Part): The 13AT2-E is classified as obsolete. Continued use is limited to existing inventory or legacy system maintenance. The part is RoHS compliant and carries standard ECCN and HTSUS classifications for electronic switches.

12TW1-1A (Substitute Part): The 12TW1-1A is an active product from the same manufacturer with identical mechanical mounting characteristics and circuit configuration. This substitute is suitable for applications where the AC voltage requirement does not exceed 125V. The part is RoHS compliant and includes environment sealing, providing enhanced ingress protection compared to the original part. The active product status ensures continued availability and supply chain reliability.

Selection Criteria:

• If the application requires 250V AC operation, the 13AT2-E specifications cannot be met by the 12TW1-1A substitute.
• If the application operates at 125V AC or lower, the 12TW1-1A is mechanically and electrically compatible for panel-mount installation.
• Termination style differences (Solder Lug vs. Solder Turret) require verification of PCB or wiring harness compatibility during integration.
• The 0.54mm difference in actuator length (30.00mm vs. 29.46mm) is within typical mechanical tolerance for panel-mount applications.

Frequently Asked Questions (FAQ)

Q: Can the 12TW1-1A directly replace the 13AT2-E in all applications?

A: No. The 12TW1-1A has a lower AC voltage rating (125V vs. 250V). Substitution is only valid for applications operating at 125V AC or lower. DC voltage specifications also differ, with the 13AT2-E rated for 30V DC and the 12TW1-1A specifications not provided for DC operation.

Q: Are the mechanical mounting dimensions identical?

A: The panel cutout dimensions (Circular - 12.40mm Dia) and bushing thread (15/32-32) are identical. The actuator length differs by 0.54mm (30.00mm vs. 29.46mm), which is typically acceptable for panel-mount applications but should be verified for specific mechanical constraints.

Q: What is the difference between Solder Lug and Solder Turret termination?

A: Solder Lug termination uses a flat tab for connection, while Solder Turret termination uses a cylindrical post. These are different connection methods requiring compatible PCB or wiring harness designs. Verify termination compatibility before substitution.

Q: Does the 12TW1-1A offer any advantages over the 13AT2-E?

A: The 12TW1-1A is an active product with current manufacturing support, whereas the 13AT2-E is obsolete. The 12TW1-1A includes environment sealing for enhanced ingress protection and specifies an operating temperature range (-65°C ~ 71°C), providing additional environmental performance data.

Q: Are both parts RoHS compliant?

A: Yes. Both the 13AT2-E and 12TW1-1A are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications.

Q: What should be verified before implementing the 12TW1-1A as a substitute?

A: Verify the application voltage requirement does not exceed 125V AC. Confirm termination style compatibility with the circuit board or wiring harness. Validate that the 0.54mm actuator length difference does not conflict with panel geometry or mechanical constraints. Confirm DC voltage requirements, as the 12TW1-1A does not specify DC ratings.
