Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMC-6010-42T is determined by the following critical parameters:

• Microphone Type: Electret condenser technology
• Output Configuration: Analog output
• Directional Pattern: Omnidirectional
• Frequency Response: 100 Hz ~ 20 kHz minimum coverage
• Impedance: 2.2 kOhms
• Voltage Compatibility: 2 V ~ 10 V operating range
• Physical Form Factor: 0.236" diameter (6.00mm) circular package
• Termination Method: Solder pads for PCB mounting

The CMC-6013-38T meets all substitution criteria. Both components share identical microphone architecture, output type, directional characteristics, frequency response specification, impedance rating, voltage operating range, physical dimensions, and termination method. Differences in sensitivity rating and supply current do not preclude substitution when the application tolerates the specified parameter variations.

Parameter Comparison

Engineering Selection Recommendations

The CMC-6013-38T is the designated manufacturer substitute for the obsolete CMC-6010-42T. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

The CMC-6013-38T offers improved supply current efficiency at 150 µA compared to the CMC-6010-42T at 500 µA, reducing power consumption in battery-operated or low-power systems. The CMC-6013-38T also provides a higher signal-to-noise ratio of 60dB versus 58dB, enhancing audio clarity in noise-sensitive applications.

The sensitivity difference of 4dB between the two components (CMC-6010-42T at -42dB versus CMC-6013-38T at -38dB) represents a measurable increase in output level for equivalent input sound pressure. Applications requiring the specific sensitivity of the CMC-6010-42T must evaluate whether the CMC-6013-38T sensitivity meets system gain structure requirements.

The CMC-6013-38T exhibits a maximum height of 0.059" (1.50mm) compared to 0.047" (1.20mm) for the CMC-6010-42T. PCB layout and enclosure clearance must accommodate this dimensional increase.

Frequently Asked Questions (FAQ)

Q: Can the CMC-6013-38T directly replace the CMC-6010-42T in existing designs?

A: The CMC-6013-38T is mechanically and electrically compatible with the CMC-6010-42T for applications tolerating the specified parameter variations. The 4dB sensitivity difference and increased height must be evaluated against design constraints. Both components share identical frequency response, impedance, voltage range, and termination specifications.

Q: What is the significance of the sensitivity difference between these microphones?

A: Sensitivity is measured in dB relative to a reference level at a specified sound pressure level. The CMC-6013-38T at -38dB produces approximately 4dB higher output voltage than the CMC-6010-42T at -42dB for identical input sound pressure. System gain structure and signal chain design must accommodate this output level difference.

Q: Does the increased height of the CMC-6013-38T affect PCB integration?

A: The CMC-6013-38T maximum height of 0.059" (1.50mm) exceeds the CMC-6010-42T height of 0.047" (1.20mm) by 0.012" (0.30mm). PCB layout, component placement, and enclosure design must verify clearance compatibility before substitution.

Q: What is the power consumption impact of substituting the CMC-6013-38T?

A: The CMC-6013-38T operates at 150 µA supply current compared to 500 µA for the CMC-6010-42T, representing a 70% reduction in microphone current draw. This improvement benefits battery-powered applications and reduces thermal load in power-constrained systems.

Q: Are both microphones compliant with current regulatory standards?

A: Both the CMC-6010-42T and CMC-6013-38T maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component manufacturing and use.
