• Sensitivity specification: -46dB ±3dB
• Impedance: 2.2 kOhms
• Voltage range: 2 V ~ 10 V
• Supply current: 500 µA
• Port location: Top

The substitute part POM-2246P-C33-R maintains all core electrical and functional parameters while introducing improvements in product status, compliance certification, and termination specification. The substitute is manufactured by the same supplier within the same product series, ensuring design compatibility.

Parameter Comparison

Engineering Selection Recommendations

The POM-2246P-C33-R is the direct equivalent substitute for the obsolete POM-2246P. Both components share identical electrical specifications across sensitivity, impedance, voltage range, and supply current parameters. The substitute part offers the following advantages:

• Active product status with current manufacturing availability
• ROHS3 compliance certification, meeting modern regulatory requirements
• Specified termination configuration (PC Pins) enabling standardized assembly integration
• Improved signal-to-noise ratio of 60dB compared to 58dB in the original part
• Documented frequency response range of 50 Hz to 16 kHz with defined physical dimensions

For applications requiring the POM-2246P, the POM-2246P-C33-R provides direct functional replacement with enhanced compliance and specification documentation.

Frequently Asked Questions (FAQ)

Q: Can POM-2246P-C33-R be used as a direct replacement for POM-2246P?

A: Yes. Both components are electret condenser microphones with identical sensitivity (-46dB ±3dB), impedance (2.2 kOhms), voltage range (2 V ~ 10 V), and supply current (500 µA) specifications. The substitute maintains all core electrical and functional parameters required for circuit compatibility.

Q: What are the key differences between these parts?

A: The primary differences are product status, compliance certification, and documentation completeness. POM-2246P-C33-R is an active product with ROHS3 compliance, while POM-2246P is obsolete and RoHS non-compliant. The substitute also specifies PC Pin termination, frequency response range, and physical dimensions not documented for the original part.

Q: Does the improved S/N ratio of POM-2246P-C33-R affect circuit design?

A: No. The S/N ratio improvement from 58dB to 60dB represents enhanced performance in the substitute part. This does not require circuit modifications and is backward compatible with designs specified for the original component.

Q: What termination type is used in POM-2246P-C33-R?

A: POM-2246P-C33-R uses PC Pins termination, providing standardized through-hole or surface-mount assembly compatibility. Verify PCB footprint alignment with your design specifications.

Q: Are there any compliance considerations when switching to POM-2246P-C33-R?

A: Yes. POM-2246P-C33-R is ROHS3 compliant, making it suitable for applications subject to RoHS regulations. The original POM-2246P is RoHS non-compliant. Both parts maintain REACH Unaffected status.
