POM-2744P Equivalent & Substitute Parts

Part Overview

The POM-2744P is an analog electret condenser microphone manufactured by PUI Audio, Inc., designed for omnidirectional audio capture with a sensitivity of -44dB ±3dB. This component operates across a voltage range of 2 V to 10 V and delivers a signal-to-noise ratio of 56dB with an impedance of 2.2 kOhms.

The POM-2744P carries an Obsolete product status, making it necessary to identify functionally equivalent alternatives for new designs and ongoing production requirements. The substitute part POM-2744P-C33-R maintains the core electrical specifications while offering enhanced performance characteristics and Active product status.

Engineering Selection Recommendations

The POM-2744P-C33-R is the designated substitute for the obsolete POM-2744P. Selection of the substitute part is based on:

• Active product status ensuring long-term availability and supply chain continuity
• ROHS3 compliance meeting current environmental and regulatory requirements
• Improved signal-to-noise ratio (60dB versus 56dB) providing enhanced audio quality
• Identical core electrical parameters ensuring direct functional replacement
• PC Pin termination providing standardized connection methodology
• Specified frequency range (50 Hz ~ 16 kHz) and physical dimensions enabling precise integration planning

Frequently Asked Questions (FAQ)

Q: Can POM-2744P-C33-R replace POM-2744P in existing designs?

A: Yes. The substitute part maintains identical sensitivity (-44dB ±3dB), voltage range (2 V ~ 10 V), impedance (2.2 kOhms), and supply current (500 µA). The PC Pin termination of the substitute part requires verification against the original termination method in the application circuit.

Q: What are the key differences between these parts?

A: The POM-2744P-C33-R provides improved signal-to-noise ratio (60dB versus 56dB), ROHS3 compliance, Active product status, and specified physical dimensions and frequency range. The original POM-2744P carries Obsolete status and RoHS non-compliant designation.

Q: Are there packaging considerations for substitution?

A: The POM-2744P-C33-R is supplied in Bulk packaging with PC Pin termination. Physical dimensions are 0.236" diameter (6.00mm) with maximum height of 0.114" (2.90mm) in a circular shape. Verify these specifications against the mechanical constraints of the target application.

Q: What compliance certifications apply to the substitute part?

A: The POM-2744P-C33-R is ROHS3 compliant and REACH Unaffected. Both parts share identical ECCN (EAR99) and HTSUS (8518.10.8030) classifications.

Q: Is the frequency response specified for the original part?

A: The POM-2744P does not include frequency range specification in the available documentation. The substitute part POM-2744P-C33-R specifies 50 Hz ~ 16 kHz frequency response, providing defined bandwidth parameters for system design.
