Key Parameters

Substitute Part Grouping Explanation

Substitution of the AML21MBE2CD is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Circuit configuration (4PDT)
• Switch function (On-On)
• Current ratings (3A AC / 2A DC)
• Voltage ratings (125V AC / 24V DC)

Mechanical Compatibility:

• Mounting type (Panel Mount, Snap-In)
• Panel cutout dimensions (Rectangular - 28.98mm x 19.05mm)
• Termination style (Solder, Quick Connect - 0.110")

Operational Compatibility:

• Mechanical life (25,000 Cycles)
• Electrical life (25,000 Cycles)

Regulatory Compliance:

• RoHS Compliant status
• MSL Rating 1

The AML21GBA2CD meets all substitution criteria as an active product within the same AML21 series, maintaining identical electrical ratings, mechanical specifications, and panel interface dimensions.

Parameter Comparison

Engineering Selection Recommendations

The AML21GBA2CD is the direct substitute for the obsolete AML21MBE2CD. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the AML21 series and maintain identical electrical, mechanical, and operational specifications.

Selection Basis:

The AML21GBA2CD is classified as an active product, ensuring ongoing availability and supply chain continuity. Both parts carry RoHS Compliant certification and MSL Rating 1, meeting current regulatory requirements. The substitute maintains the same 4PDT circuit configuration, 3A/125V AC and 2A/24V DC ratings, panel mount snap-in installation, and 25,000-cycle mechanical and electrical life specifications.

The identical panel cutout dimensions (28.98mm x 19.05mm) and termination style (Solder, Quick Connect - 0.110") ensure direct mechanical and electrical compatibility in existing panel installations without modification.

Frequently Asked Questions (FAQ)

Q: Can AML21GBA2CD directly replace AML21MBE2CD in existing applications?

A: Yes. Both components share identical electrical ratings (3A/125V AC, 2A/24V DC), circuit configuration (4PDT), mounting specifications (Panel Mount, Snap-In), panel cutout dimensions (28.98mm x 19.05mm), and termination style (Solder, Quick Connect - 0.110"). Direct substitution is supported without circuit or panel modifications.

Q: What is the difference between AML21MBE2CD and AML21GBA2CD?

A: The primary difference is product status. AML21MBE2CD is obsolete, while AML21GBA2CD is active. All electrical, mechanical, and operational parameters are identical. The packaging differs (AML21MBE2CD is packaged individually; AML21GBA2CD is packaged in bulk), but this does not affect component functionality.

Q: Are both parts RoHS compliant?

A: Yes. Both AML21MBE2CD and AML21GBA2CD are RoHS Compliant and carry MSL Rating 1 (Unlimited), meeting current environmental and moisture sensitivity requirements.

Q: What is the illumination voltage for these switches?

A: The AML21MBE2CD specifies 28 VAC nominal illumination voltage. The AML21GBA2CD does not specify this parameter in the provided data, but both components feature incandescent illumination and are electrically identical.

Q: Can these switches handle both AC and DC applications?

A: Yes. Both switches are rated for 3A at 125V AC and 2A at 24V DC, supporting dual-voltage applications within these specified limits.

Q: What is the mechanical and electrical life expectancy?

A: Both components are rated for 25,000 cycles of mechanical life and 25,000 cycles of electrical life under specified operating conditions.
