AML21LBE2AD Equivalent & Substitute Parts

Part Overview

The AML21LBE2AD is a pushbutton switch manufactured by Honeywell Sensing and Productivity Solutions, configured as a Double Pole Double Throw (DPDT) illuminated panel mount switch with snap-in mounting. The switch is rated for 3A AC at 125V and 2A DC at 24V, featuring incandescent illumination at 28 VAC nominal. This part is classified as obsolete, making identification of equivalent substitute components essential for ongoing maintenance, repair, and system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AML21LBE2AD is determined by strict equivalence across the following critical parameters:

Circuit and Electrical Specifications: The substitute must maintain DPDT configuration with On-On switch function, 3A AC at 125V, and 2A DC at 24V ratings.

Illumination Characteristics: Incandescent illumination type at 28 VAC nominal voltage must be preserved.

Mechanical Interface: Panel mount snap-in mounting with rectangular actuator type and identical panel cutout dimensions (28.98mm x 19.05mm) is required.

Termination: Solder and quick connect 0.110" (2.8mm) termination style must be maintained.

Lifecycle Ratings: Mechanical and electrical life of 25,000 cycles must be met.

Compliance: RoHS compliance and MSL 1 rating must be retained.

The AML21GBE2AD meets all these criteria and is classified as an equivalent substitute within the AML21 series.

Parameter Comparison

Engineering Selection Recommendations

The AML21GBE2AD is the direct equivalent substitute for the obsolete AML21LBE2AD. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the same AML21 series and share identical electrical, mechanical, and functional specifications.

Product Status Advantage: The AML21GBE2AD maintains active product status, ensuring continued availability and manufacturer support, whereas the AML21LBE2AD is classified as obsolete.

Compliance Alignment: Both parts maintain RoHS compliance and MSL 1 rating, meeting current regulatory and environmental standards.

Functional Equivalence: All critical parameters—circuit configuration (DPDT), current ratings (3A AC / 2A DC), voltage ratings (125V AC / 24V DC), illumination specifications (incandescent at 28 VAC), mounting interface (panel mount snap-in), termination style (solder and quick connect 0.110"), and lifecycle ratings (25,000 cycles mechanical and electrical)—are identical between the two parts.

Direct Replacement: The AML21GBE2AD can be used as a direct replacement in applications currently using the AML21LBE2AD without modification to circuit design, panel cutout dimensions, or electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can the AML21GBE2AD be used as a direct replacement for the AML21LBE2AD?

A: Yes. The AML21GBE2AD is a direct equivalent substitute. All electrical ratings, mechanical dimensions, mounting interface, illumination specifications, and lifecycle ratings are identical. The primary difference is product status: AML21GBE2AD is active while AML21LBE2AD is obsolete.

Q: What are the key electrical specifications that define substitution compatibility?

A: Substitution compatibility is determined by DPDT circuit configuration, On-On switch function, 3A AC at 125V rating, 2A DC at 24V rating, incandescent illumination at 28 VAC nominal, and 25,000 cycle mechanical and electrical life ratings.

Q: Are the panel cutout dimensions identical between these parts?

A: Yes. Both the AML21LBE2AD and AML21GBE2AD require a rectangular panel cutout of 28.98mm x 19.05mm. No panel modification is required when substituting between these parts.

Q: What is the termination configuration for both parts?

A: Both parts use solder and quick connect termination with 0.110" (2.8mm) connector spacing. Wiring harnesses and connection methods are compatible.

Q: Are both parts RoHS compliant?

A: Yes. Both the AML21LBE2AD and AML21GBE2AD are RoHS compliant with MSL 1 (unlimited moisture sensitivity level).

Q: Why is the AML21LBE2AD classified as obsolete?

A: The AML21LBE2AD is listed as obsolete by the manufacturer. The AML21GBE2AD is the active equivalent within the AML21 series and is the recommended part for new designs and ongoing procurement.

Q: What is the difference in packaging between these parts?

A: The AML21LBE2AD is supplied with standard packaging, while the AML21GBE2AD is supplied in bulk packaging. This does not affect component functionality or specifications.

Q: Can the illumination voltage be adjusted on either part?

A: No. Both parts are designed for 28 VAC nominal illumination voltage. This specification is fixed and cannot be adjusted.
