AML22CBB3AD Equivalent & Substitute Parts

Part Overview

The AML22CBB3AD is a Double Pole Double Throw (DPDT) illuminated pushbutton switch manufactured by Honeywell Sensing and Productivity Solutions. This panel-mount, snap-in component is rated for 3A at 125V AC and 2A at 24V DC, with integrated red LED illumination. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AML22CBB3AD is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Current ratings must support minimum 3A at 125V AC and 2A at 24V DC
• Illumination type must be LED with red color

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Snap-In
• Panel cutout dimensions must be Square - 19.05mm x 19.05mm
• Termination style must be PC Pin
• Mechanical and electrical life must meet or exceed 25,000 cycles

Compliance Requirements:

• RoHS Compliant status required
• Moisture Sensitivity Level (MSL) 1 or equivalent

The AML22JBF3AD meets all electrical, mechanical, and compliance criteria for direct substitution. The primary difference is the illumination voltage specification (24 VDC versus 2.4 VDC) and the inclusion of a Full Guard Bezel feature. Both parts share identical circuit topology, current/voltage ratings, mounting specifications, and lifecycle ratings.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: AML22JBF3AD

The AML22JBF3AD is the direct functional equivalent for the obsolete AML22CBB3AD. Both components share identical electrical specifications, mechanical mounting characteristics, and lifecycle ratings within the AML22 series.

Product Status Consideration: The AML22CBB3AD is classified as obsolete, while the AML22JBF3AD maintains active product status with Honeywell. For new designs and ongoing system support, the AML22JBF3AD is the appropriate selection.

Illumination Voltage Difference: The illumination voltage differs between the two parts (2.4 VDC versus 24 VDC). This difference requires circuit-level evaluation. Systems designed for the AML22CBB3AD with 2.4 VDC illumination supply must be modified to accommodate the 24 VDC requirement of the AML22JBF3AD, or alternative illumination supply provisions must be implemented.

Mechanical Enhancement: The AML22JBF3AD includes a Full Guard Bezel feature not present in the AML22CBB3AD. This feature provides additional environmental protection and mechanical durability without affecting electrical performance or panel cutout compatibility.

Compliance Status: Both parts maintain RoHS Compliance and MSL 1 (Unlimited) ratings, ensuring regulatory and environmental compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can the AML22JBF3AD be used as a direct replacement for the AML22CBB3AD without circuit modification?

A: Electrical and mechanical compatibility is confirmed. However, the illumination voltage specification differs (24 VDC versus 2.4 VDC). Direct substitution requires that the illumination supply circuit be capable of providing 24 VDC, or the illumination function must be redesigned. The switch contacts and mechanical mounting are fully compatible.

Q: What is the significance of the Full Guard Bezel feature on the AML22JBF3AD?

A: The Full Guard Bezel provides enhanced environmental protection and mechanical durability around the switch actuator. This feature does not affect electrical performance, current/voltage ratings, or panel cutout dimensions. It represents an engineering improvement in the active product variant.

Q: Are both parts suitable for 125V AC and 24V DC applications?

A: Yes. Both the AML22CBB3AD and AML22JBF3AD are rated for 3A at 125V AC and 2A at 24V DC. Electrical specifications are identical across both components.

Q: Why is the AML22CBB3AD classified as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The AML22JBF3AD represents the active continuation of this switch type within the AML22 series, incorporating the Full Guard Bezel enhancement.

Q: Do both parts use the same panel cutout dimensions?

A: Yes. Both components require a square panel cutout of 19.05mm x 19.05mm and utilize snap-in mounting. Panel modifications are not required when substituting between these parts.

Q: What is the mechanical and electrical life expectancy for both parts?

A: Both the AML22CBB3AD and AML22JBF3AD are rated for 25,000 mechanical cycles and 25,000 electrical cycles, providing equivalent operational longevity.

Q: Are both parts RoHS compliant?

A: Yes. Both components maintain RoHS Compliance status and MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements.
