MB6022ASC-1L Equivalent & Substitute Parts

Part Overview

The MB6022ASC-1L 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 -42dB ±3dB at 94dB SPL, suitable for embedded audio systems and consumer electronics. The product is currently obsolete, necessitating identification of functionally equivalent alternatives to maintain design continuity and support ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB6022ASC-1L is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Microphone type: Electret Condenser
• Output configuration: Analog
• Directional pattern: Omnidirectional
• Sensitivity: -42dB ±3dB @ 94dB SPL
• Voltage range: 2 V ~ 10 V (minimum 2 V rated, maximum 10 V operating)
• Supply current: 500 µA
• Impedance: 2.2 kOhms
• Physical dimensions: 0.236" diameter (6.00mm), 0.094" maximum height (2.40mm)
• Shape: Circular

Allowable Variations:

• Frequency range may extend beyond 100 Hz ~ 10 kHz (wider ranges are acceptable)
• Termination type may differ (solder pads vs. PC pins) based on PCB design compatibility
• S/N ratio may vary within acceptable engineering tolerances
• Product status may differ (active vs. obsolete)

The CMC-2242PBL-A meets all critical matching parameters and is identified as a manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The CMC-2242PBL-A is a direct functional equivalent to the MB6022ASC-1L based on matching electrical specifications and physical dimensions. Key selection considerations:

Product Availability: The CMC-2242PBL-A maintains active product status with confirmed inventory availability (1111 Pcs), whereas the MB6022ASC-1L is obsolete. This substitution ensures continued supply chain access for production and maintenance applications.

Compliance Status: The CMC-2242PBL-A is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement in regulated markets.

Frequency Response Extension: The CMC-2242PBL-A extends the upper frequency limit to 20 kHz compared to the original 10 kHz specification. This represents an enhancement that does not compromise compatibility with designs specified for the narrower bandwidth.

Termination Compatibility: The transition from solder pads to PC pins requires PCB design verification to confirm mechanical and electrical compatibility with existing footprints and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the CMC-2242PBL-A directly replace the MB6022ASC-1L in existing designs?

A: Electrical compatibility is confirmed across all critical parameters: sensitivity, impedance, voltage range, supply current, and frequency response. Mechanical compatibility depends on PCB footprint design. The solder pad termination of the original part differs from the PC pin termination of the substitute, requiring verification that the PCB layout accommodates the pin configuration.

Q: What is the significance of the extended frequency range in the CMC-2242PBL-A?

A: The CMC-2242PBL-A operates from 100 Hz to 20 kHz, extending 10 kHz beyond the MB6022ASC-1L specification. This wider bandwidth is a superset of the original specification and does not introduce incompatibility. Designs specified for 100 Hz ~ 10 kHz operation remain fully functional.

Q: How do the S/N ratios compare between these parts?

A: The MB6022ASC-1L specifies 60dB S/N ratio, while the CMC-2242PBL-A specifies 58dB. Both values fall within acceptable engineering tolerances for analog microphone applications. The 2dB difference does not materially impact audio quality in typical embedded audio capture scenarios.

Q: What are the compliance implications of selecting the CMC-2242PBL-A?

A: The CMC-2242PBL-A is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. Both parts carry EAR99 ECCN classification and identical HTSUS codes, indicating equivalent trade compliance status.

Q: Are there inventory considerations for this substitution?

A: The CMC-2242PBL-A is currently in active production with 1111 Pcs available inventory. The MB6022ASC-1L is obsolete with limited remaining stock (702 Pcs). For new production or long-term supply planning, the CMC-2242PBL-A is the recommended selection.
