POM-5246P-R Equivalent & Substitute Parts

Part Overview

The POM-5246P-R is an electret condenser microphone manufactured by PUI Audio, Inc., designed for analog applications requiring omnidirectional pickup patterns. This component operates across a 2 V to 10 V supply range with a sensitivity specification of -48dB ±3dB and a frequency response spanning 30 Hz to 15 kHz. The product is currently classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system designs and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the POM-5246P-R is determined by the following critical parameters:

• Microphone type: Electret condenser construction
• Output configuration: Analog signal output
• Directional pattern: Omnidirectional response
• Voltage compatibility: 2 V minimum supply requirement
• Current draw: 500 µA supply current
• Physical form factor: Circular shape, 0.236" diameter, PC pin termination
• Port location: Top-mounted configuration

The POM-5046P-C3310-R meets these substitution criteria while maintaining mechanical and electrical compatibility with the original POM-5246P-R design envelope.

Parameter Comparison

Engineering Selection Recommendations

The POM-5046P-C3310-R serves as the direct substitute for the obsolete POM-5246P-R. Both components share identical mechanical dimensions (0.236" diameter), electrical supply requirements (2 V rated, 500 µA current draw), and functional architecture (electret condenser, analog output, omnidirectional pattern, PC pin termination).

The POM-5046P-C3310-R is currently in active production status with ROHS3 compliance and REACH unaffected certification, providing regulatory alignment for new designs and ongoing procurement. The sensitivity differential of 2dB (-46dB versus -48dB) and S/N ratio reduction of 5dB represent measurable but acceptable trade-offs within typical analog microphone application tolerances.

Frequently Asked Questions (FAQ)

Q: Can the POM-5046P-C3310-R directly replace the POM-5246P-R in existing designs?

A: Yes. Both components maintain identical physical form factors (0.236" diameter, PC pin termination), rated voltage (2 V), and supply current (500 µA). The 2dB sensitivity difference falls within normal application tolerance ranges for analog microphone circuits.

Q: What is the significance of the sensitivity difference between these parts?

A: The POM-5246P-R operates at -48dB ±3dB sensitivity, while the POM-5046P-C3310-R operates at -46dB ±3dB. This 2dB difference represents a measurable increase in output level for the substitute part. Circuit gain adjustments may be required to maintain consistent signal levels in applications with fixed gain stages.

Q: Are there compliance or regulatory differences between these components?

A: The POM-5046P-C3310-R carries ROHS3 compliance and REACH unaffected certification. The original POM-5246P-R compliance status is not specified. For applications subject to regulatory requirements, the substitute part provides documented compliance documentation.

Q: What is the height difference between these microphones?

A: The POM-5246P-R has a maximum height of 0.213" (5.40mm), while the POM-5046P-C3310-R has a maximum height of 0.205" (5.20mm). This 0.008" (0.20mm) difference is negligible for most mechanical mounting applications.

Q: Why is the original POM-5246P-R classified as obsolete?

A: Product obsolescence typically results from manufacturer discontinuation decisions. The POM-5046P-C3310-R represents the active production equivalent within the PUI Audio POM series, ensuring long-term component availability and supply chain continuity.
