Frequently Asked Questions (FAQ)

Q: Can the POM-2242P-C33-R be used as a direct replacement for the POM-2242P?

A: Yes. Both components share identical sensitivity (-42dB ±3dB), impedance (2.2 kOhms), voltage range (2V ~ 10V), current consumption (500 µA), termination style (PC Pins), and physical dimensions (0.236" diameter, 0.094" height). The POM-2242P-C33-R is electrically and mechanically compatible with designs specified for the POM-2242P.

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

A: The primary differences are product status, compliance, and performance specifications. The POM-2242P-C33-R is an active product with ROHS3 compliance, while the POM-2242P is obsolete and RoHS non-compliant. The POM-2242P-C33-R also specifies a frequency response range (50 Hz ~ 16 kHz) and provides a 2dB improvement in signal-to-noise ratio (60dB versus 58dB).

Q: Are there packaging differences between these parts?

A: The POM-2242P-C33-R is supplied in bulk packaging, while packaging information for the POM-2242P is not specified. Both components use identical PC pin termination and circular form factor.

Q: Does the improved S/N ratio of the POM-2242P-C33-R affect circuit design?

A: No. The improved signal-to-noise ratio (60dB versus 58dB) represents enhanced performance without requiring circuit modifications. The electrical interface, impedance, and voltage requirements remain unchanged.

Q: Are there compliance considerations for selecting between these parts?

A: Yes. The POM-2242P-C33-R meets ROHS3 compliance requirements, making it suitable for applications subject to current regulatory standards. The obsolete POM-2242P is RoHS non-compliant and should not be specified for new designs or applications requiring regulatory compliance.
