Omron A16L-AAM-24-1 Pushbutton Switch SPDT Equivalent & Substitute Parts

Part Overview

The Omron A16L-AAM-24-1 is a panel-mount illuminated pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 125V AC. This component features incandescent blue illumination at 24 VAC/DC and is designed for momentary (On-Mom) operation with a 16mm circular panel cutout. The part is currently listed as obsolete, making identification of compatible substitutes essential for ongoing maintenance and new designs requiring equivalent functionality.

Substitute Part Grouping Explanation

The A16L-AAM-24-1 can be directly substituted with the A16L-AAM-24D-1 based on the following matching parameters:

• Circuit configuration: Both SPDT
• Current rating: Both 5A (AC)
• Voltage rating: Both 125V AC
• Switch function: Both On-Mom (momentary)
• Mounting type: Both panel mount, front
• Panel cutout dimensions: Both circular 16.00mm diameter
• Actuator type: Both square button
• Actuator color: Both blue
• Termination style: Both solder and quick connect 0.110" (2.8mm)
• Ingress protection: Both IP40
• Operating temperature range: Both -10°C ~ 55°C
• Mechanical life: Both 2,000,000 cycles
• Electrical life: Both 100,000 cycles
• RoHS compliance: Both compliant

The primary difference between these parts is the illumination type: the A16L-AAM-24-1 uses incandescent illumination at 24 VAC/DC, while the A16L-AAM-24D-1 uses LED illumination at 24 VDC. Both illumination options are blue and operate at the same nominal voltage rating, making them functionally equivalent for panel-mount applications.

Parameter Comparison

Engineering Selection Recommendations

The A16L-AAM-24D-1 is the direct substitute for the obsolete A16L-AAM-24-1. Both parts maintain identical electrical and mechanical specifications across all critical parameters including circuit configuration, current and voltage ratings, switch function, mounting dimensions, and lifecycle ratings. Both components are RoHS compliant and operate within the same temperature range.

The A16L-AAM-24D-1 offers the advantage of active product status, ensuring continued availability and supply chain reliability. The transition from incandescent to LED illumination in the substitute part represents a modern component evolution while maintaining functional equivalence. The LED variant operates at 24 VDC, whereas the original part accepts both 24 VAC and 24 VDC illumination supply. For applications requiring AC illumination supply exclusively, this difference must be evaluated against the availability and long-term support benefits of the active substitute part.

Frequently Asked Questions (FAQ)

Q: Can the A16L-AAM-24D-1 directly replace the A16L-AAM-24-1 in existing installations?

A: Yes. Both parts share identical electrical ratings (5A, 125V AC), circuit configuration (SPDT), switch function (On-Mom), panel cutout dimensions (16mm circular), and termination style. The primary difference is illumination type: incandescent (original) versus LED (substitute). If your application uses 24 VDC illumination supply, the substitute is fully compatible. If your application uses 24 VAC illumination supply exclusively, the substitute's 24 VDC-only specification must be considered.

Q: What is the significance of the product status change from Obsolete to Active?

A: The A16L-AAM-24-1 is obsolete and no longer manufactured. The A16L-AAM-24D-1 is an active product with ongoing manufacturing and supply chain support. Selecting the active substitute ensures long-term component availability and reduces the risk of future supply disruptions.

Q: Are the mechanical and electrical life ratings identical between these parts?

A: Yes. Both the A16L-AAM-24-1 and A16L-AAM-24D-1 are rated for 2,000,000 mechanical cycles and 100,000 electrical cycles, ensuring equivalent operational durability.

Q: What is the difference between incandescent and LED illumination in these switches?

A: The A16L-AAM-24-1 uses incandescent illumination, while the A16L-AAM-24D-1 uses LED illumination. Both provide blue illumination at the same nominal voltage rating (24V). LED illumination typically offers longer operational life and lower power consumption compared to incandescent technology.

Q: Are both parts RoHS compliant?

A: Yes. Both the A16L-AAM-24-1 and A16L-AAM-24D-1 are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

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

A: Yes. Both parts require a circular 16.00mm diameter panel cutout, ensuring mechanical compatibility in existing panel designs without modification.
