Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB6052ASC-1 is determined by strict alignment of the following critical parameters:

• Microphone Type: Electret condenser technology
• Output Configuration: Analog output
• Directional Pattern: Omnidirectional
• Electrical Compatibility: Voltage range 2 V ~ 10 V, impedance 2.2 kOhms, supply current 500 µA
• Mechanical Compatibility: Circular form factor 0.236" diameter (6.00mm), solder pad termination
• Frequency Response: Minimum coverage of 100 Hz ~ 10 kHz range
• Sensitivity Range: Within ±3dB tolerance specification

The CMC-5044TF-A from CUI Devices meets all substitution criteria while maintaining active product status and enhanced frequency response capability.

Engineering Selection Recommendations

The CMC-5044TF-A is the qualified substitute for the obsolete MB6052ASC-1. Selection is based on the following engineering criteria:

Electrical Compatibility: Both components operate identically across the 2 V ~ 10 V supply range with matching impedance (2.2 kOhms) and current draw (500 µA), ensuring direct circuit-level compatibility without modification to power delivery or signal conditioning stages.

Mechanical Compatibility: Identical 0.236" (6.00mm) diameter and solder pad termination enable direct PCB footprint compatibility. The CMC-5044TF-A height of 0.205" (5.20mm) is reduced compared to the original 0.213" (5.40mm), providing improved spatial efficiency in compact designs.

Functional Equivalence: Both microphones deliver omnidirectional analog output with matching 60dB signal-to-noise ratio. The CMC-5044TF-A sensitivity of -44dB ±3dB remains within the ±3dB tolerance specification of the original -42dB ±3dB specification, ensuring equivalent acoustic performance in system-level applications.

Regulatory and Compliance Status: The CMC-5044TF-A holds active product status with ROHS3 compliance certification, providing long-term supply assurance and regulatory alignment for production environments. Both components maintain REACH Unaffected and EAR99 ECCN classifications.

Enhanced Capability: The CMC-5044TF-A extends frequency response to 20 kHz, providing additional bandwidth beyond the original 10 kHz specification without introducing incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the CMC-5044TF-A be used as a direct replacement for the MB6052ASC-1 without circuit modifications?

A: Yes. The CMC-5044TF-A maintains identical electrical specifications (voltage range, impedance, supply current) and mechanical form factor (diameter, termination type, footprint), enabling direct substitution without circuit redesign or PCB layout changes.

Q: What is the significance of the sensitivity difference between -42dB and -44dB?

A: Both specifications include ±3dB tolerance bands, resulting in overlapping acceptable ranges. The -44dB specification of the CMC-5044TF-A falls within the tolerance envelope of the original -42dB specification, maintaining equivalent acoustic performance in system applications.

Q: Does the extended frequency response of the CMC-5044TF-A (20 kHz vs. 10 kHz) affect compatibility?

A: No. Extended frequency response is a non-breaking enhancement. Applications designed for 10 kHz operation will function identically; systems requiring extended bandwidth benefit from the additional capability without requiring design changes.

Q: Are there any height clearance considerations when substituting the CMC-5044TF-A?

A: The CMC-5044TF-A is 0.008" (0.20mm) shorter than the original component. This reduction improves spatial efficiency and presents no compatibility issues for designs with existing height clearance for the MB6052ASC-1.

Q: What is the supply status difference between these components?

A: The MB6052ASC-1 is obsolete and no longer manufactured. The CMC-5044TF-A is an active product with ongoing production and supply availability, ensuring long-term component sourcing for new designs and production continuity.

Q: Are both components subject to the same regulatory classifications?

A: Yes. Both the MB6052ASC-1 and CMC-5044TF-A maintain identical REACH Unaffected and EAR99 ECCN classifications. The CMC-5044TF-A additionally carries ROHS3 compliance certification, providing enhanced regulatory alignment for current manufacturing standards.
