Key Parameters

Substitute Part Grouping Explanation

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

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

The POM-3546P-R qualifies as a direct substitute based on full alignment with all electrical and mechanical parameters listed above. The primary distinction between these parts is product status and regulatory compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The POM-3546P-R is the direct substitute for the obsolete POM-3546P. Both components share identical electrical performance specifications and mechanical form factors, ensuring functional equivalence in circuit applications.

The POM-3546P-R carries active product status, indicating ongoing manufacturer support and availability. This part also achieves ROHS3 compliance, whereas the original POM-3546P is RoHS non-compliant. For applications subject to RoHS regulatory requirements or environmental compliance mandates, the POM-3546P-R is the appropriate selection.

Both parts maintain REACH Unaffected status and unlimited moisture sensitivity classification (MSL 1), indicating no special handling or storage constraints.

Frequently Asked Questions (FAQ)

Q: Can the POM-3546P-R be used as a direct replacement for the POM-3546P?

A: Yes. The POM-3546P-R is electrically and mechanically equivalent to the POM-3546P. All critical parameters—sensitivity, impedance, voltage range, supply current, termination style, and physical dimensions—are identical between the two parts.

Q: What is the primary difference between these two part numbers?

A: The POM-3546P-R is the active production variant with ROHS3 compliance. The original POM-3546P is obsolete and RoHS non-compliant. The POM-3546P-R also includes a specified frequency range of 30 Hz ~ 15 kHz, whereas the original part does not document this parameter.

Q: Are there packaging differences between POM-3546P and POM-3546P-R?

A: The POM-3546P-R is supplied in bulk packaging, whereas the original POM-3546P packaging specification is not detailed in the available data. Confirm packaging requirements with your procurement or supply chain team.

Q: Does the POM-3546P-R require special handling or storage?

A: No. Both the POM-3546P and POM-3546P-R carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints or special storage conditions are required.

Q: Are both parts suitable for RoHS-regulated applications?

A: Only the POM-3546P-R meets RoHS3 compliance requirements. The original POM-3546P is RoHS non-compliant and is not suitable for applications subject to RoHS directives.
