Substitute Part Grouping Explanation

Substitution eligibility for the POM-2246P-2 is determined by strict equivalence across the following critical parameters:

• Microphone type: Electret condenser
• Output configuration: Analog
• Directional pattern: Omnidirectional
• Sensitivity specification: -46dB ±3dB
• Signal-to-noise ratio: 60dB
• Impedance: 2.2 kOhms
• Operating voltage range: 2V ~ 10V
• Supply current: 500 µA
• Mechanical form factor: 0.236" diameter circular, 0.094" maximum height
• Termination style: PC pins
• Port orientation: Top-mounted

The POM-2246P-2-R qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The POM-2246P-2-R serves as the direct functional equivalent to the obsolete POM-2246P-2. Both components maintain identical electrical performance specifications and mechanical dimensions, ensuring drop-in compatibility within existing circuit designs.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The POM-2246P-2-R carries active product status from the manufacturer, providing assured long-term availability and supply chain continuity. Additionally, the POM-2246P-2-R meets ROHS3 compliance requirements, whereas the original POM-2246P-2 does not. For applications subject to RoHS directives or requiring components with current regulatory certification, the POM-2246P-2-R is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the POM-2246P-2-R replace the POM-2246P-2 in existing designs?

A: Yes. The POM-2246P-2-R is electrically and mechanically identical to the POM-2246P-2. All electrical parameters, impedance characteristics, sensitivity ratings, and physical dimensions are equivalent. PC pin termination and top-mounted port orientation are identical, enabling direct substitution without circuit modification.

Q: What is the primary reason to transition from POM-2246P-2 to POM-2246P-2-R?

A: The POM-2246P-2 is classified as obsolete. The POM-2246P-2-R maintains active product status, ensuring manufacturer support and continued availability. Additionally, the POM-2246P-2-R meets ROHS3 compliance standards.

Q: Are there packaging differences between these parts?

A: The POM-2246P-2 is supplied in standard packaging, while the POM-2246P-2-R is supplied in bulk packaging. This distinction affects order quantities and handling but does not impact component performance or compatibility.

Q: What are the critical parameters that define substitution eligibility for this microphone?

A: Substitution requires equivalence across microphone type (electret condenser), output configuration (analog), directional pattern (omnidirectional), sensitivity (-46dB ±3dB), impedance (2.2 kOhms), operating voltage range (2V ~ 10V), supply current (500 µA), and mechanical form factor (0.236" diameter, 0.094" height, circular, top-mounted PC pins).
