Key Parameters

Substitute Part Grouping Explanation

Substitution of the PNM-5250L-R is determined by strict equivalence across the following critical parameters:

• Microphone type: Electret condenser
• Output configuration: Analog
• Directional characteristic: Noise cancelling
• Sensitivity specification: -50dB ±4dB
• Supply current: 500 µA
• Termination method: Solder pads
• Physical form factor: 0.236" diameter circular package

The substitute part PNM-5050L-C3310-R meets all these criteria. While minor variations exist in rated voltage (2 V vs. 1.5 V) and S/N ratio (55dB vs. 60dB), the substitute maintains functional compatibility within the specified voltage operating range of 1.5 V to 10 V and preserves the core noise-cancelling microphone functionality.

Parameter Comparison

Engineering Selection Recommendations

The PNM-5050L-C3310-R is the direct substitute for the obsolete PNM-5250L-R. Both components are manufactured by PUI Audio, Inc., and share identical sensitivity, supply current, termination method, and physical dimensions. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The PNM-5050L-C3310-R carries ROHS3 compliance certification, meeting current environmental and regulatory standards. The substitute maintains the same noise-cancelling analog microphone functionality with equivalent electrical performance for applications operating within the specified voltage range.

Frequently Asked Questions (FAQ)

Q: Can the PNM-5050L-C3310-R directly replace the PNM-5250L-R in existing designs?

A: Yes. Both components share identical sensitivity (-50dB ±4dB), supply current (500 µA), termination (solder pads), and physical form factor (0.236" diameter). The substitute operates within the same voltage range and maintains equivalent noise-cancelling performance.

Q: What is the difference in rated voltage between these parts?

A: The PNM-5250L-R has a rated voltage of 1.5 V, while the PNM-5050L-C3310-R is rated at 2 V. Both components operate across the 1.5 V to 10 V range, ensuring compatibility in applications using standard supply voltages.

Q: Does the height difference affect mechanical compatibility?

A: The PNM-5050L-C3310-R has a maximum height of 0.205" (5.20mm) compared to 0.213" (5.40mm) for the PNM-5250L-R. This 0.008" difference is negligible for most mechanical mounting applications and does not affect solder pad compatibility.

Q: Why is the original part marked as obsolete?

A: The PNM-5250L-R is classified as obsolete by the manufacturer. The PNM-5050L-C3310-R is the active production equivalent, ensuring continued availability and support for new and replacement applications.

Q: Are there compliance differences between these parts?

A: The PNM-5050L-C3310-R carries ROHS3 compliance certification. Both parts are classified under ECCN EAR99 and HTSUS 8518.10.8030, with moisture sensitivity level 1 (unlimited).
