MB6052USZ-2 Equivalent & Substitute Parts

Part Overview

The MB6052USZ-2 is an electret condenser microphone manufactured by Knowles, designed for analog audio capture applications requiring unidirectional pickup patterns. This component operates across a 1.5 V to 10 V supply range with a sensitivity of -44dB ±3dB at 94dB SPL and covers a frequency range of 100 Hz to 10 kHz. The product is currently obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB6052USZ-2 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Microphone type: Electret Condenser
• Output configuration: Analog
• Directional pattern: Unidirectional
• Termination method: Solder Pads
• Physical form factor: Circular, 0.236" diameter (6.00mm)
• Impedance: 2.2 kOhms
• Supply current: 500 µA
• Voltage range overlap: Minimum 1.5 V to 10 V compatibility

Allowable Parameter Variations:

• Frequency range may extend beyond the original specification
• Sensitivity may vary within ±3dB tolerance band
• Height may differ provided mechanical fit is maintained
• Product status may transition from obsolete to active

The PUM-3546L-R from PUI Audio, Inc. meets all mandatory compatibility criteria and represents an active product alternative.

Parameter Comparison

Engineering Selection Recommendations

The PUM-3546L-R qualifies as a direct substitute for the MB6052USZ-2 based on the following engineering factors:

Functional Equivalence: Both components share identical core specifications for microphone type, output configuration, directional pattern, impedance, supply current, and termination method. The electrical interface and mechanical mounting footprint are compatible.

Product Lifecycle Advantage: The PUM-3546L-R maintains active product status with current manufacturing support and documented availability (5547 units in stock), whereas the MB6052USZ-2 is obsolete. This transition ensures long-term supply chain continuity and access to technical documentation.

Compliance and Certification: The PUM-3546L-R carries RoHS3 compliance certification, providing enhanced environmental and regulatory alignment compared to the obsolete predecessor. Both components maintain REACH Unaffected status and identical ECCN/HTSUS classifications.

Performance Characteristics: The substitute component extends frequency response coverage (30 Hz to 15 kHz versus 100 Hz to 10 kHz) and maintains sensitivity within the ±3dB tolerance specification. The reduced maximum height (3.70mm versus 5.40mm) provides design flexibility for space-constrained applications.

Voltage Compatibility: The PUM-3546L-R operates across a 2 V to 10 V range, which overlaps the original 1.5 V to 10 V specification. Applications requiring operation below 2 V must be evaluated for compatibility.

Frequently Asked Questions (FAQ)

Q: Can the PUM-3546L-R directly replace the MB6052USZ-2 in existing designs?

A: Yes, the PUM-3546L-R is electrically and mechanically compatible with the MB6052USZ-2. Both components share identical impedance (2.2 kOhms), supply current (500 µA), solder pad termination, and 6.00mm circular form factor. The substitute operates within the same voltage range for most applications, with the exception of designs requiring operation below 2 V.

Q: What are the key differences between these two microphones?

A: The primary differences are product status (active versus obsolete), frequency response extension (30 Hz to 15 kHz versus 100 Hz to 10 kHz), physical height (3.70mm versus 5.40mm), and compliance certifications (RoHS3 for the substitute). Sensitivity specifications remain within tolerance, and impedance is identical.

Q: Are there any voltage supply considerations when substituting?

A: The PUM-3546L-R minimum rated voltage is 2 V, compared to 1.5 V for the MB6052USZ-2. Applications operating at 1.5 V supply voltage require verification that the substitute component functions within specification at this reduced voltage level.

Q: Does the reduced height of the PUM-3546L-R affect mechanical compatibility?

A: The PUM-3546L-R has a maximum height of 3.70mm compared to 5.40mm for the MB6052USZ-2. This lower profile is mechanically compatible with existing mounting structures and may provide design advantages for space-constrained applications. The identical 6.00mm diameter and solder pad termination ensure footprint compatibility.

Q: What is the supply chain status for each component?

A: The MB6052USZ-2 is obsolete with no active manufacturing. The PUM-3546L-R is an active product with 5547 units currently in stock, ensuring reliable availability and ongoing technical support.

Q: Are there any compliance or certification differences?

A: The PUM-3546L-R carries RoHS3 compliance certification, providing enhanced environmental compliance. Both components maintain REACH Unaffected status and share identical ECCN (EAR99) and HTSUS (8518.10.8030) classifications.
