Key Parameters

Substitute Part Grouping Explanation

Substitution of the POM-5242P-R is determined by strict equivalence across the following critical parameters:

• Microphone Type: Electret condenser technology
• Output Configuration: Analog signal output
• Directional Pattern: Omnidirectional pickup
• Sensitivity Level: -42dB ±3dB
• Signal-to-Noise Ratio: 60dB minimum
• Supply Voltage Compatibility: 2V rated with 2V ~ 10V operational range
• Current Consumption: 500 µA supply current
• Mechanical Interface: PC pin termination
• Physical Envelope: 0.236" diameter (6.00mm) circular form factor
• Port Orientation: Top-mounted audio port

The POM-5042P-C3310-R meets all substitution criteria as an active product from the same manufacturer within the POM series, maintaining identical electrical performance specifications and mechanical compatibility.

Engineering Selection Recommendations

The POM-5042P-C3310-R is the direct functional equivalent for the obsolete POM-5242P-R. Selection is based on the following engineering criteria:

Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Electrical Equivalence: Both parts operate identically across all specified electrical parameters including sensitivity, impedance, supply voltage range, and current consumption. No circuit modifications are required.

Mechanical Compatibility: The substitute maintains the same 0.236" diameter circular form factor, PC pin termination, and top-mounted port configuration. The height difference of 0.008" (0.20mm) is within typical PCB assembly tolerances and does not affect mechanical fit in standard microphone mounting applications.

Regulatory Compliance: The substitute part carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronic component procurement.

Packaging: The substitute is supplied in box packaging, suitable for standard component handling and inventory management.

Frequently Asked Questions (FAQ)

Q: Can the POM-5042P-C3310-R be used as a direct replacement for the POM-5242P-R without circuit modifications?

A: Yes. Both parts share identical electrical specifications including sensitivity (-42dB ±3dB), impedance (2.2 kOhms), supply voltage range (2V ~ 10V), and current consumption (500 µA). PC pin termination and omnidirectional characteristics are identical. No circuit redesign is necessary.

Q: What is the significance of the 0.008" height difference between the two parts?

A: The POM-5042P-C3310-R has a maximum height of 0.205" compared to 0.213" for the POM-5242P-R. This 0.008" (0.20mm) difference is negligible for standard PCB assembly and does not affect mechanical fit in typical microphone mounting applications.

Q: Does the substitute part meet current environmental standards?

A: Yes. The POM-5042P-C3310-R is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement in most jurisdictions.

Q: Why is the main part classified as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions. The active substitute part provides equivalent functionality and ensures continued availability for applications requiring this microphone specification.

Q: Are there any differences in packaging between the two parts?

A: The main part packaging is not specified in available documentation. The substitute part is supplied in box packaging, which is standard for component distribution and inventory management.

Q: What parameters must remain constant when selecting a substitute for this microphone?

A: Critical parameters for substitution include microphone type (electret condenser), output type (analog), directional pattern (omnidirectional), sensitivity (-42dB ±3dB), S/N ratio (60dB), supply voltage (2V rated, 2V ~ 10V range), current consumption (500 µA), termination type (PC pins), and physical form factor (0.236" diameter circular).
