Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the POM-3542L is determined by strict equivalence across the following critical parameters:

• Microphone type: Electret condenser
• Output configuration: Analog
• Directional pattern: Omnidirectional
• Sensitivity specification: -42dB ±3dB
• Signal-to-noise ratio: 60dB
• Impedance: 2.2 kOhms
• Supply voltage range: 2 V ~ 10 V
• Supply current: 500 µA
• Termination method: Solder pads
• Physical dimensions: 0.236" diameter, 0.146" maximum height, circular shape

The POM-3542L-R meets all substitution criteria and is classified as a direct equivalent within the POM series.

Parameter Comparison

Engineering Selection Recommendations

The POM-3542L-R is the direct substitute for the obsolete POM-3542L. Both components share identical electrical and mechanical specifications across all critical parameters: sensitivity, impedance, voltage range, current consumption, and physical dimensions.

The primary distinction between the two parts is product status and regulatory compliance. The POM-3542L-R is classified as active and meets ROHS3 compliance requirements, whereas the original POM-3542L is obsolete and RoHS non-compliant. For new designs or ongoing production requiring regulatory compliance with modern environmental standards, the POM-3542L-R is the appropriate selection.

Both components are manufactured by PUI Audio, Inc., and maintain identical performance characteristics within the POM series. The POM-3542L-R is available in bulk packaging with current inventory of 837 pieces.

Frequently Asked Questions (FAQ)

Q: Can the POM-3542L-R be used as a direct replacement for the POM-3542L?

A: Yes. The POM-3542L-R meets all electrical and mechanical specifications of the POM-3542L, including sensitivity (-42dB ±3dB), impedance (2.2 kOhms), voltage range (2 V ~ 10 V), supply current (500 µA), and physical dimensions (0.236" diameter, 0.146" height). Both components feature identical solder pad termination and omnidirectional pickup patterns.

Q: What is the primary difference between these two parts?

A: The POM-3542L is obsolete, while the POM-3542L-R is active. Additionally, the POM-3542L-R is ROHS3 compliant, whereas the original part is RoHS non-compliant. Functionally and electrically, the components are equivalent.
