POM-3546L Equivalent & Substitute Parts

Part Overview

The POM-3546L is an analog electret condenser microphone manufactured by PUI Audio, Inc., designed for omnidirectional audio capture applications. This microphone operates within a 2 V to 10 V supply range and delivers a sensitivity of -46dB ±3dB with a 60dB signal-to-noise ratio. The component features solder pad termination and a circular form factor with 0.236" diameter and 0.146" maximum height.

The POM-3546L is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this microphone.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the POM-3546L is determined by strict alignment across the following critical parameters:

• Microphone type: Electret Condenser
• Output configuration: Analog
• Directional pattern: Omnidirectional
• Sensitivity specification: -46dB ±3dB
• Signal-to-noise ratio: 60dB
• Impedance: 2.2 kOhms
• Voltage range: 2 V ~ 10 V
• Supply current: 500 µA
• Termination method: Solder Pads
• Physical dimensions: 0.236" diameter, 0.146" maximum height
• Circular form factor

The POM-3546L-R qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction is product status: POM-3546L-R is active and RoHS3 compliant, whereas the original POM-3546L is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The POM-3546L-R is the direct substitute for the obsolete POM-3546L. Both components share identical electrical specifications and mechanical dimensions, ensuring functional compatibility in existing circuit designs.

Selection of POM-3546L-R is supported by the following factors:

• Active product status ensures ongoing availability and supply chain support
• ROHS3 compliance satisfies regulatory requirements for new designs and manufacturing environments where RoHS compliance is mandated
• Identical electrical performance across all specified parameters eliminates the need for circuit redesign or performance revalidation
• Solder pad termination and circular form factor maintain mechanical compatibility with existing PCB layouts

For applications where RoHS compliance is not a requirement, either component may be selected based on availability and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can POM-3546L-R be used as a direct replacement for POM-3546L in existing designs?

A: Yes. The POM-3546L-R maintains identical electrical specifications (sensitivity, impedance, voltage range, supply current, S/N ratio) and mechanical dimensions (0.236" diameter, 0.146" height, solder pad termination). No circuit modifications are required.

Q: What is the primary difference between POM-3546L and POM-3546L-R?

A: The POM-3546L-R is the active production variant with ROHS3 compliance. The original POM-3546L is obsolete and RoHS non-compliant. Both components deliver identical performance in analog omnidirectional microphone applications.

Q: Are there packaging differences between these parts?

A: The POM-3546L-R is supplied in bulk packaging, whereas the original POM-3546L packaging specification is not detailed in the available data. Confirm packaging requirements with your procurement process.

Q: What are the critical parameters for substitution eligibility?

A: Substitution requires alignment on microphone type (electret condenser), output type (analog), directional pattern (omnidirectional), sensitivity (-46dB ±3dB), impedance (2.2 kOhms), voltage range (2 V ~ 10 V), supply current (500 µA), termination method (solder pads), and physical dimensions (0.236" diameter, 0.146" height).

Q: Is RoHS compliance a factor in selecting between these parts?

A: RoHS compliance is a regulatory and manufacturing environment consideration. If your application or manufacturing location requires RoHS3 compliance, POM-3546L-R is the appropriate selection. For applications without RoHS requirements, either part may be used based on availability.
