AML12CBF3EA Equivalent & Substitute Parts Reference

Part Overview

The AML12CBF3EA is a pushbutton Hall Effect switch manufactured by Honeywell Sensing and Productivity Solutions. This component operates at 0.4 V output and functions as a single-circuit, momentary-contact switch with a supply voltage range of 4.5 to 24 VDC. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations. The part features panel mount, snap-in installation with PC pin termination and maintains RoHS compliance with MSL Level 1 rating.

Substitute Part Grouping Explanation

The AML22CBF3AA is identified as a direct substitute for the AML12CBF3EA based on the following substitution criteria:

Mechanical Compatibility:

• Both parts feature panel mount, snap-in mounting configuration
• Both utilize PC pin termination style
• Both accommodate square button actuators (not included)
• Both are manufactured by Honeywell Sensing and Productivity Solutions within the same product family

Electrical Compatibility:

• Both parts operate within overlapping voltage ranges (AML22CBF3AA supports 24 VDC DC rating, compatible with AML12CBF3EA's 4.5–24 VDC supply range)
• Both maintain RoHS compliance and MSL Level 1 rating
• Both are suitable for panel-mounted control applications

Functional Differences: The AML22CBF3AA operates as a SPDT (Single Pole Double Throw) standard illuminated switch with On-Mom function, whereas the AML12CBF3EA is a single-circuit Hall Effect switch with Off-Mom function. The AML22CBF3AA includes integrated LED illumination (red, 24 VDC nominal) and higher current ratings (3A AC / 2A DC), making it suitable for applications requiring visual feedback and higher switching capacity.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The AML22CBF3AA is suitable as a substitute for the AML12CBF3EA in applications where the following conditions are met:

• Panel mount, snap-in installation is required
• PC pin termination is compatible with existing PCB layouts
• Operating voltage does not exceed 24 VDC
• The SPDT circuit configuration and On-Mom function are acceptable for the application logic
• Higher current switching capacity (3A AC / 2A DC) does not create design conflicts

Product Status Consideration: The AML12CBF3EA is obsolete, while the AML22CBF3AA maintains active product status with documented mechanical and electrical life ratings (25,000 cycles). This active status ensures ongoing availability and manufacturer support.

Compliance: Both parts maintain RoHS compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the AML22CBF3AA directly replace the AML12CBF3EA in existing designs?

A: The AML22CBF3AA shares identical mechanical mounting (panel mount, snap-in) and termination (PC pin) with the AML12CBF3EA. However, circuit configuration differs (SPDT vs. single circuit) and switch function differs (On-Mom vs. Off-Mom). Substitution requires verification that the application logic accommodates these functional differences.

Q: What is the primary reason for substitution?

A: The AML12CBF3EA is classified as obsolete. The AML22CBF3AA is an active product from the same manufacturer family, ensuring continued availability and support.

Q: Are there packaging differences between these parts?

A: The AML12CBF3EA packaging is listed as "-" (not specified). The AML22CBF3AA is supplied in bulk packaging. Both parts feature identical panel cutout dimensions (square 19.05 mm × 19.05 mm) for snap-in installation.

Q: What voltage range is compatible with both parts?

A: The AML12CBF3EA operates at 4.5–24 VDC. The AML22CBF3AA is rated for 24 VDC DC operation. Applications operating at 24 VDC are compatible with both parts.

Q: Does the AML22CBF3AA include illumination?

A: Yes. The AML22CBF3AA features integrated red LED illumination at 24 VDC nominal. The AML12CBF3EA does not include illumination. This is a functional addition in the substitute part.

Q: What are the mechanical life specifications?

A: The AML12CBF3EA mechanical life is not specified. The AML22CBF3AA is rated for 25,000 mechanical cycles and 25,000 electrical cycles, providing documented durability for design calculations.

Q: Are both parts RoHS compliant?

A: Yes. Both the AML12CBF3EA and AML22CBF3AA are RoHS compliant with MSL Level 1 (unlimited moisture sensitivity level), suitable for standard manufacturing and storage environments.
