MB6022ABC-3 Equivalent & Substitute Parts

Part Overview

The MB6022ABC-3 is an electret condenser microphone manufactured by Knowles, designed for analog audio capture applications requiring omnidirectional pickup patterns. This component operates across a 100 Hz to 10 kHz frequency range with a sensitivity of -45dB ±2dB at 94dB SPL, suitable for low-power applications with supply voltages between 3 V and 10 V. The product is classified as obsolete, making identification of compatible substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the MB6022ABC-3 are qualified based on the following critical parameters that determine functional compatibility:

Electrical Compatibility:

• Microphone type: Electret condenser
• Output configuration: Analog
• Directional pattern: Omnidirectional
• Impedance: 2.2 kOhms
• S/N ratio: 60dB minimum
• Supply current: 500 µA
• Voltage range overlap with original specification (3 V ~ 10 V)

Mechanical Compatibility:

• Physical diameter: 0.236" (6.00mm)
• Maximum height: 0.094" (2.40mm)
• Circular shape
• Termination type: Solderless (Bullseye)
• Port location: Top

Acoustic Compatibility:

• Frequency response: 100 Hz ~ 10 kHz minimum coverage
• Sensitivity within ±3dB tolerance of original specification

The POM-2246S-2-R meets these criteria with minor parameter variations within acceptable engineering tolerances for this component category.

Parameter Comparison

Engineering Selection Recommendations

The POM-2246S-2-R from PUI Audio, Inc. is qualified as a direct substitute for the obsolete MB6022ABC-3. The substitute maintains identical mechanical form factor, electrical impedance, and supply current specifications. The POM-2246S-2-R carries active product status with RoHS3 compliance, providing long-term availability and regulatory alignment for new designs or production continuity.

Sensitivity variation between the two components (-45dB versus -46dB) falls within standard engineering tolerance for analog microphone applications and does not preclude functional substitution. The extended lower voltage rating of the POM-2246S-2-R (2 V minimum versus 3 V) provides additional operational flexibility without compromising compatibility with existing 3 V to 10 V supply designs.

Both components maintain identical REACH and ECCN classifications, ensuring consistent regulatory and export compliance status.

Frequently Asked Questions (FAQ)

Q: Can the POM-2246S-2-R replace the MB6022ABC-3 in existing designs?

A: Yes. Both components share identical mechanical dimensions, electrical impedance, supply current, and termination type. The substitute operates within the original voltage range and maintains compatible acoustic performance across the specified frequency band.

Q: What is the sensitivity difference between these microphones?

A: The MB6022ABC-3 specifies -45dB ±2dB sensitivity, while the POM-2246S-2-R specifies -46dB ±3dB. This 1dB nominal difference is within standard tolerance for electret condenser microphones and does not affect functional compatibility in typical audio applications.

Q: Does the POM-2246S-2-R support the same voltage range?

A: The POM-2246S-2-R operates from 2 V to 10 V, compared to the original 3 V to 10 V range. Designs operating at 3 V or higher experience no compatibility issues. Applications requiring operation below 3 V must evaluate the substitute's performance at the lower voltage threshold.

Q: Are the physical dimensions identical?

A: Yes. Both microphones are 0.236" (6.00mm) in diameter with a maximum height of 0.094" (2.40mm). Both use circular form factors with top-mounted ports and solderless Bullseye termination, ensuring direct mechanical compatibility in PCB layouts and mechanical assemblies.

Q: What is the compliance status of the substitute part?

A: The POM-2246S-2-R is RoHS3 compliant and maintains REACH unaffected status, matching the regulatory classification of the original component. Both parts carry identical ECCN (EAR99) and HTSUS classifications.
