MD6022APC-0 Equivalent & Substitute Parts

Part Overview

The MD6022APC-0 is an electret condenser microphone manufactured by Knowles, designed for omnidirectional audio capture across the 100 Hz to 10 kHz frequency range with a sensitivity of -42dB ±3dB. This component features PC pin termination and a compact 0.236" diameter circular form factor. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MD6022APC-0 are qualified based on the following critical parameters that determine functional compatibility:

Core Substitution Criteria:

• Microphone type: Electret Condenser
• Directional pattern: Omnidirectional
• Sensitivity: -42dB ±3dB (matching specification)
• Impedance: 2.2 kOhms (matching specification)
• Termination: PC Pins
• Physical form factor: 0.236" Dia (6.00mm) circular
• Port location: Top

Allowable Parameter Variations:

• Frequency range: Extended ranges are acceptable (original 100 Hz ~ 10 kHz; substitutes may extend to 50 Hz ~ 20 kHz)
• Voltage rating: Substitutes rated for 2 V minimum with extended range capability (2 V ~ 10 V) are acceptable
• S/N ratio: Higher values indicate improved performance and are acceptable
• Height: Slight variations within mechanical envelope constraints are acceptable
• Product status: Active products are preferred over obsolete alternatives

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts meet the core electrical and mechanical requirements for direct replacement of the MD6022APC-0:

CMC-2242PBL-A (CUI Devices) is an active product with ROHS3 compliance and extended frequency response (100 Hz ~ 20 kHz). This part provides improved S/N ratio (58dB) and supports extended voltage operation (2 V ~ 10 V). The maximum height of 0.094" represents a 0.003" increase over the original specification, which remains within typical mechanical tolerances for microphone assemblies.

POM-2242P-C33-R (PUI Audio) is an active product with ROHS3 compliance and the widest frequency range (50 Hz ~ 16 kHz). This part delivers the highest S/N ratio (60dB) among available substitutes and supports extended voltage operation (2 V ~ 10 V). The maximum height of 0.094" is identical to the CUI Devices alternative.

Both substitutes are manufactured by active suppliers with current product status, ensuring long-term availability and supply chain stability compared to the obsolete MD6022APC-0.

Frequently Asked Questions (FAQ)

Q: Can CMC-2242PBL-A or POM-2242P-C33-R be used as direct replacements for MD6022APC-0?

A: Yes. Both substitute parts match the critical parameters: electret condenser type, omnidirectional pattern, -42dB ±3dB sensitivity, 2.2 kOhms impedance, PC pin termination, and 0.236" diameter form factor. Extended frequency ranges and improved S/N ratios represent performance enhancements rather than incompatibilities.

Q: What is the significance of the height difference (0.087" vs. 0.094")?

A: The substitute parts are 0.007" taller than the original MD6022APC-0. This difference must be evaluated against the mechanical constraints of the host assembly. In most applications with standard microphone mounting provisions, this variation remains within acceptable tolerances.

Q: Why do the substitute parts specify voltage ranges (2 V ~ 10 V) when the original only lists 2 V?

A: The substitute parts are designed to operate across a wider voltage range while maintaining specified performance at the 2 V rated voltage. This extended capability provides design flexibility for systems requiring higher supply voltages without affecting compatibility with 2 V applications.

Q: What does the "@ 94dB SPL" notation in the CMC-2242PBL-A sensitivity specification mean?

A: This indicates the sensitivity measurement was taken at a 94dB Sound Pressure Level reference condition. The -42dB ±3dB sensitivity value remains equivalent to the original specification for substitution purposes.

Q: Are there compliance or regulatory differences between the original and substitute parts?

A: The substitute parts carry ROHS3 compliance certification, indicating adherence to current environmental and material restriction standards. The original MD6022APC-0 does not specify RoHS status. Both substitutes maintain REACH Unaffected status, matching the original part's regulatory profile.

Q: Which substitute part should be selected for new designs?

A: Selection between CMC-2242PBL-A and POM-2242P-C33-R depends on specific application requirements. Both are active products with equivalent substitution capability. The POM-2242P-C33-R offers the highest S/N ratio (60dB) and lowest frequency extension (50 Hz), while CMC-2242PBL-A provides the highest frequency extension (20 kHz).
