Key Parameters

Substitute Part Grouping Explanation

Substitution of the PNM-3546L-R is determined by strict equivalence across the following critical parameters:

• Microphone type: Electret condenser
• Output configuration: Analog
• Directional characteristic: Noise cancelling
• Sensitivity specification: -46dB ±4dB
• Supply voltage compatibility: 2 V ~ 10 V operation
• Current consumption: 500 µA
• Physical form factor: 0.236" diameter circular package
• Termination method: Solder pads
• Port orientation: Top-mounted

The substitute PNM-3546L-C3310-R maintains all critical electrical and mechanical parameters required for direct functional replacement within the same application context.

Parameter Comparison

Engineering Selection Recommendations

The PNM-3546L-C3310-R is the direct substitute for the obsolete PNM-3546L-R. Both components share identical electrical performance specifications and mechanical form factors. The substitute part is currently in active production status, ensuring availability for new designs and replacement applications.

The PNM-3546L-C3310-R carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution. The S/N ratio difference of 5dB (60dB versus 55dB) represents a minor variance within acceptable engineering tolerances for noise cancellation applications and does not preclude functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the PNM-3546L-C3310-R be used as a direct replacement for the PNM-3546L-R?

A: Yes. Both components are electret condenser microphones with identical sensitivity (-46dB ±4dB), frequency response (50 Hz ~ 16 kHz), supply current (500 µA), physical dimensions (0.236" diameter, 0.146" height), and solder pad termination. Electrical and mechanical compatibility is confirmed.

Q: What is the significance of the S/N ratio difference between the two parts?

A: The main part specifies 60dB S/N ratio while the substitute specifies 55dB. This 5dB difference falls within typical manufacturing variance for electret condenser microphones and does not affect functional substitution for noise cancellation applications.

Q: Are there packaging differences between these parts?

A: The main part PNM-3546L-R does not specify packaging detail. The substitute PNM-3546L-C3310-R is supplied in box packaging. Both use identical solder pad termination for PCB integration.

Q: Does the substitute part meet current regulatory standards?

A: Yes. The PNM-3546L-C3310-R is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Why is the original part listed as obsolete?

A: The PNM-3546L-R is designated obsolete by the manufacturer. The PNM-3546L-C3310-R is the active production equivalent, ensuring continued availability and support for this microphone specification.
