Key Parameters

Substitute Part Grouping Explanation

The POM-3046P-R serves as a direct substitute based on strict equivalence of all critical electrical and mechanical parameters. Substitution validity is determined by the following criteria:

Electrical Parameters (Must Match):

• Sensitivity: -46dB ±3dB
• S/N Ratio: 60dB
• Impedance: 2.2 kOhms
• Voltage Range: 2V ~ 10V
• Current Supply: 500 µA
• Output Type: Analog
• Direction: Omnidirectional

Mechanical Parameters (Must Match):

• Size / Dimension: 0.236" Dia (6.00mm)
• Height (Max): 0.126" (3.20mm)
• Termination: PC Pins
• Port Location: Top
• Shape: Circular

The POM-3046P-R maintains complete alignment with all specified parameters, confirming direct substitutability for the obsolete POM-3046P.

Engineering Selection Recommendations

The POM-3046P-R is the appropriate selection for new designs and production continuity. The substitute part maintains complete electrical and mechanical equivalence to the obsolete POM-3046P while offering the following advantages:

Product Status: The POM-3046P-R carries Active product status, ensuring ongoing manufacturer support, availability, and supply chain reliability compared to the Obsolete classification of the original part.

Compliance: The POM-3046P-R is ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing. The original POM-3046P is RoHS non-compliant, which may present compliance challenges in regulated applications and markets.

Availability: The POM-3046P-R demonstrates higher inventory levels (1002 Pcs) compared to the POM-3046P (728 Pcs), supporting production scalability and supply security.

All critical electrical parameters—sensitivity, impedance, voltage range, and current supply—remain identical between the two parts, confirming direct functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the POM-3046P-R be used as a direct replacement for the POM-3046P?

A: Yes. The POM-3046P-R maintains identical electrical specifications (sensitivity, impedance, voltage range, current supply) and mechanical dimensions (0.236" diameter, 0.126" height, PC pin termination). Both parts are omnidirectional analog electret condenser microphones from the same manufacturer series.

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

A: The POM-3046P-R is an Active product with ROHS3 compliance, while the POM-3046P is Obsolete and RoHS non-compliant. The substitute also specifies a frequency range of 30 Hz ~ 15 kHz, which was not documented for the original part.

Q: Are there packaging differences between the POM-3046P and POM-3046P-R?

A: The POM-3046P-R is supplied in Bulk packaging, while the original POM-3046P packaging designation is not specified. Both parts use identical PC pin termination and circular form factor.

Q: Does the POM-3046P-R meet current regulatory requirements?

A: Yes. The POM-3046P-R is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components. The original POM-3046P is RoHS non-compliant.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts share identical sensitivity (-46dB ±3dB), S/N ratio (60dB), impedance (2.2 kOhms), voltage range (2V ~ 10V), and current supply (500 µA) specifications.
