EM-23346-C54 Equivalent & Substitute Parts

Part Overview

The EM-23346-C54 is a Knowles electret condenser microphone designed for analog audio applications requiring omnidirectional pickup patterns. This component operates across a 100 Hz to 10 kHz frequency range with a sensitivity of -52dB ±3dB at 74dB SPL, making it suitable for compact audio capture in consumer and industrial applications.

The EM-23346-C54 carries an Obsolete product status, indicating that Knowles has discontinued active production and support for this model. Organizations currently using this component in active designs or requiring additional inventory must identify functionally equivalent alternatives to ensure supply chain continuity and long-term product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EM-23346-C54 is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Microphone Type: Electret Condenser
• Output Type: Analog
• Direction: Omnidirectional
• Sensitivity: -52dB ±3dB @ 74dB SPL
• Impedance: 4.4 kOhms
• Current - Supply: 50 µA
• Termination: Solder Pads
• Physical Dimensions: 0.141" L x 0.141" W (4.67mm x 4.67mm)
• Height (Max): 0.090" (2.28mm)
• Shape: Square

Allowable Variation Parameters:

• Frequency Range: The EM-23346-C54 operates from 100 Hz to 10 kHz. Substitute parts with narrower frequency ranges (such as 100 Hz to 5 kHz) remain functionally compatible for applications that do not require the extended upper frequency response.
• Voltage - Rated: The EM-23346-C54 is rated at 1.3 V. Substitute parts with expanded voltage operating ranges (such as 0.9 V to 1.6 V) provide enhanced flexibility for variable supply conditions while maintaining compatibility with the nominal 1.3 V specification.
• Packaging: Variations in packaging format (such as Tray versus other configurations) do not affect electrical or mechanical compatibility.

The EM-23346-C36 meets all mandatory matching criteria and falls within allowable variation parameters, qualifying it as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The EM-23346-C36 is the qualified substitute for the EM-23346-C54. Both components maintain identical electrical performance characteristics, physical form factors, and regulatory compliance certifications (ROHS3).

The EM-23346-C54 is classified as Obsolete, indicating end-of-life status with no ongoing manufacturing or support. The EM-23346-C36 carries a Not For New Designs designation, reflecting a transitional product status that provides greater availability than the fully obsolete EM-23346-C54 while maintaining full functional compatibility.

The frequency range difference (10 kHz versus 5 kHz upper limit) does not impact substitution suitability for applications operating within the 100 Hz to 5 kHz band. Applications requiring response beyond 5 kHz must evaluate alternative component families.

Both components are ROHS3 compliant and carry identical mechanical specifications, ensuring direct compatibility in existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the EM-23346-C36 directly replace the EM-23346-C54 in existing designs?

A: Yes. The EM-23346-C36 maintains identical electrical specifications, physical dimensions, and termination methods. Direct substitution is supported without PCB layout modifications or signal chain redesign.

Q: What is the significance of the frequency range difference between these parts?

A: The EM-23346-C54 specifies a 100 Hz to 10 kHz frequency response, while the EM-23346-C36 specifies 100 Hz to 5 kHz. For applications operating within the 100 Hz to 5 kHz band, this difference is not functionally significant. Applications requiring response above 5 kHz must confirm that the EM-23346-C36 meets their specific frequency requirements before substitution.

Q: Are there packaging differences between these parts?

A: The EM-23346-C54 is supplied in standard packaging, while the EM-23346-C36 is supplied in Tray packaging. Packaging format does not affect electrical performance or mechanical compatibility. Component handling and storage procedures should follow the specifications for Tray-packaged components.

Q: What does the "Not For New Designs" status mean for the EM-23346-C36?

A: Not For New Designs indicates that Knowles is not recommending this component for incorporation into new product development. However, it remains functionally equivalent and available for replacement in existing designs. For new designs, consultation with Knowles regarding current-generation alternatives is recommended.

Q: Are both components RoHS compliant?

A: Yes. Both the EM-23346-C54 and EM-23346-C36 are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
