PUM-3046L Equivalent & Substitute Parts

Part Overview

The PUM-3046L is an analog electret condenser microphone manufactured by PUI Audio, Inc., designed for unidirectional audio capture with a sensitivity of -46dB ±3dB. This component features a compact circular form factor (0.236" diameter) and operates across a 2V to 10V supply range with solder pad termination for direct PCB integration.

The PUM-3046L is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing production requirements, system redesigns, or inventory replenishment where original stock is unavailable or depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PUM-3046L is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Microphone type: Electret Condenser
• Output type: Analog
• Directional pattern: Unidirectional
• Sensitivity range: -46dB (tolerance variance acceptable within engineering limits)
• Impedance: 2.2 kOhms
• Voltage range: 2V ~ 10V minimum
• Current supply: 500 µA
• Termination method: Solder Pads
• Physical form factor: Circular, 0.236" diameter, 0.126" maximum height
• Port location: Top

The PUM-3046L-R qualifies as a direct substitute based on full alignment with all mandatory parameters. The substitute maintains identical electrical specifications, mechanical dimensions, and interface characteristics required for drop-in replacement in existing PCB designs.

Parameter Comparison

Engineering Selection Recommendations

The PUM-3046L-R is the qualified substitute for the obsolete PUM-3046L based on the following engineering criteria:

Electrical Compatibility: The substitute maintains identical voltage range (2V ~ 10V), current consumption (500 µA), impedance (2.2 kOhms), and S/N ratio (60dB). Sensitivity tolerance variance (-46dB ±4dB versus -46dB ±3dB) represents a ±1dB widening and remains within acceptable engineering limits for analog microphone applications.

Mechanical Compatibility: Identical physical dimensions (0.236" diameter, 0.126" maximum height), circular form factor, top port location, and solder pad termination ensure direct PCB compatibility without layout modifications.

Compliance Status: The PUM-3046L-R is ROHS3 compliant and REACH unaffected, addressing current regulatory requirements. The original PUM-3046L is RoHS non-compliant, making the substitute the appropriate choice for new designs or compliance-driven applications.

Production Status: The PUM-3046L-R is in active production with substantial inventory availability (5856 pcs), ensuring supply chain reliability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the PUM-3046L-R be used as a direct replacement for the PUM-3046L in existing designs?

A: Yes. The PUM-3046L-R is a direct substitute with identical electrical specifications, mechanical dimensions, and interface characteristics. No PCB redesign or circuit modifications are required for drop-in replacement.

Q: What is the difference in sensitivity tolerance between the two parts?

A: The PUM-3046L specifies -46dB ±3dB sensitivity, while the PUM-3046L-R specifies -46dB ±4dB. The substitute tolerance is ±1dB wider. Both parts maintain the same nominal -46dB sensitivity value and are functionally equivalent for analog microphone applications.

Q: Does the PUM-3046L-R include frequency response specifications?

A: Yes. The PUM-3046L-R is specified with a frequency range of 30 Hz ~ 15 kHz. The original PUM-3046L does not include frequency range documentation in the available data.

Q: What are the compliance differences between these parts?

A: The PUM-3046L is RoHS non-compliant. The PUM-3046L-R is ROHS3 compliant. Both parts are REACH unaffected. For applications requiring RoHS compliance, the PUM-3046L-R is the required selection.

Q: Are there packaging differences between the PUM-3046L and PUM-3046L-R?

A: The original PUM-3046L packaging is not specified in available data. The PUM-3046L-R is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the supply status for each part?

A: The PUM-3046L is obsolete with 1097 pcs available in current inventory. The PUM-3046L-R is in active production with 5856 pcs available. For long-term supply assurance, the PUM-3046L-R is the recommended selection.
