Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB6022APC-0 is determined by the following critical parameters:

Microphone Type and Output Configuration: Both the main part and substitute must be electret condenser microphones with analog output to maintain signal compatibility with existing amplification and processing circuits.

Directional Characteristics: Omnidirectional pickup pattern is required to preserve the acoustic behavior of the original design.

Physical Form Factor: Circular shape with 0.236" diameter (6.00mm) and maximum height of 0.094" (2.40mm) ensures mechanical compatibility with existing PCB layouts and enclosure constraints.

Electrical Interface: PC pin termination is mandatory for direct board-level integration without adapter components.

Operating Voltage and Current: Voltage range of 2 V to 10 V and supply current of 500 µA must be supported to ensure compatibility with existing power supply and biasing circuits.

Impedance Matching: 2.2 kOhms impedance maintains proper signal coupling with downstream audio processing stages.

Audio Performance Parameters: Frequency response, sensitivity, and signal-to-noise ratio must fall within acceptable ranges for the intended application. Sensitivity tolerance and frequency bandwidth variations are permissible within engineering design margins.

Parameter Comparison

Engineering Selection Recommendations

The POM-2242P-C33-R from PUI Audio, Inc. is a direct functional substitute for the obsolete MB6022APC-0. Both components share identical physical dimensions, electrical interface specifications, impedance characteristics, and power supply requirements.

The POM-2242P-C33-R maintains active product status, ensuring ongoing availability and supply chain continuity. The substitute part is RoHS3 compliant, providing regulatory alignment with current manufacturing standards.

Performance variations between the two parts are within acceptable engineering tolerances. The POM-2242P-C33-R exhibits a wider frequency response (50 Hz to 16 kHz versus 100 Hz to 10 kHz) and slightly lower sensitivity (-42dB ±3dB versus -40dB ±2dB), representing marginal differences that do not preclude substitution in applications designed around the original MB6022APC-0 specifications.

Both components maintain identical signal-to-noise ratio (60dB), impedance (2.2 kOhms), and electrical operating parameters, confirming compatibility at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can the POM-2242P-C33-R be used as a direct replacement for the MB6022APC-0 without circuit modifications?

A: Yes. Both components share identical physical dimensions, PC pin termination, impedance, voltage range, and supply current specifications. Direct board-level substitution is supported without circuit redesign.

Q: What are the differences in frequency response between these two microphones?

A: The MB6022APC-0 operates from 100 Hz to 10 kHz, while the POM-2242P-C33-R extends from 50 Hz to 16 kHz. The substitute part provides broader frequency coverage, which is compatible with applications designed for the original part's narrower bandwidth.

Q: How do the sensitivity specifications compare?

A: The MB6022APC-0 has a sensitivity of -40dB ±2dB at 94dB SPL, while the POM-2242P-C33-R is rated at -42dB ±3dB. The 2dB difference in nominal sensitivity and the wider tolerance band of the substitute part represent acceptable variations for analog microphone applications.

Q: Are there any compliance or regulatory differences between these parts?

A: The POM-2242P-C33-R is RoHS3 compliant, while the MB6022APC-0 is obsolete and no longer subject to active compliance tracking. Both parts are REACH unaffected and carry the same ECCN and HTSUS classifications.

Q: What is the packaging format for the substitute part?

A: The POM-2242P-C33-R is supplied in bulk packaging, consistent with standard microphone component distribution for manufacturing environments.

Q: Are the mechanical dimensions identical between the two parts?

A: Yes. Both the MB6022APC-0 and POM-2242P-C33-R are circular microphones with a 0.236" diameter (6.00mm) and maximum height of 0.094" (2.40mm), ensuring identical PCB footprint compatibility.
