Substitute Part Grouping Explanation

Substitution eligibility for the EK-23027 is determined by strict equivalence across the following critical parameters:

• Microphone Type: Electret condenser technology
• Output Configuration: Analog output
• Directional Pattern: Omnidirectional
• Frequency Response: 100 Hz ~ 10 kHz
• Sensitivity: -53dB ±2dB @ 74dB SPL
• Impedance: 4.4 kOhms
• Supply Current: 50 µA
• Termination Method: Solder pads
• Physical Dimensions: 0.219" L x 0.157" W (5.56mm x 3.99mm)
• Maximum Height: 0.089" (2.26mm)

The EK-23027-C36 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Variations in voltage rating and port location do not affect functional compatibility within the specified operating range.

Parameter Comparison

Engineering Selection Recommendations

The EK-23027-C36 is the qualified substitute for the obsolete EK-23027. Both components share identical electrical performance specifications and physical dimensions, ensuring direct functional compatibility in existing circuit designs.

The EK-23027-C36 offers the advantage of active product status, ensuring continued availability and supply chain reliability. The substitute carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for new product development and manufacturing.

The voltage range difference (0.9 V ~ 10 V for EK-23027 versus 1.3 V ~ 10 V for EK-23027-C36) does not impact compatibility in applications operating within the 1.3 V to 10 V window. Systems requiring operation below 1.3 V must retain the original EK-23027 specification or conduct circuit redesign validation.

Frequently Asked Questions (FAQ)

Q: Can the EK-23027-C36 replace the EK-23027 in existing designs?

A: Yes. The EK-23027-C36 matches all critical electrical and mechanical parameters of the EK-23027, including frequency response, sensitivity, impedance, supply current, and physical dimensions. Direct substitution is supported for applications operating within the 1.3 V to 10 V supply range.

Q: What is the difference between the EK-23027 and EK-23027-C36?

A: The primary differences are product status (obsolete versus active), packaging format (unspecified versus bulk), port location (side versus top), and regulatory compliance (ROHS3 certification on the substitute). Electrical performance and physical dimensions are identical.

Q: Does the port location difference affect circuit compatibility?

A: Port location (side versus top) is a mechanical consideration related to PCB layout and assembly. Electrical performance remains unchanged. Circuit designs must accommodate the physical placement of the substitute component.

Q: Is the EK-23027-C36 suitable for new product development?

A: Yes. The EK-23027-C36 is an active product with ROHS3 compliance, making it appropriate for new designs. The obsolete status of the EK-23027 makes the EK-23027-C36 the recommended choice for ongoing development and production.

Q: What supply voltage range should be used for the EK-23027-C36?

A: The EK-23027-C36 operates across 1.3 V to 10 V. Applications requiring operation below 1.3 V are not supported by this substitute and require alternative component selection or circuit modification.
