Substitute Part Grouping Explanation

Substitution eligibility for the EM-24347-C36 is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Microphone type: Electret Condenser
• Output type: Analog
• Directional pattern: Omnidirectional
• Frequency range: 300 Hz ~ 5.8 kHz
• Impedance: 4.4 kOhms
• Voltage range: 0.9 V ~ 1.6 V
• Supply current: 50 µA
• Termination method: Solder Pads
• Physical dimensions: 0.141" L x 0.141" W (4.67mm x 4.67mm)
• Maximum height: 0.090" (2.28mm)
• Shape: Square

The EM-24447-C36 qualifies as a direct substitute based on complete alignment with all mandatory parameters. The primary distinction between these parts is sensitivity specification: the EM-24347-C36 operates at -54.5dB ±4dB, while the EM-24447-C36 operates at -58.5dB ±4dB. Both sensitivity values fall within acceptable operational ranges for omnidirectional electret condenser microphones in this form factor and remain functionally compatible within applications designed for the EM-24347-C36.
