Key Parameters

Substitute Part Grouping Explanation

Substitution of the TOM-3044L-R is determined by strict equivalence across the following critical parameters:

• Microphone type: Electret condenser
• Output configuration: Analog
• Directional pattern: Omnidirectional
• Electrical interface: Solder pad termination
• Physical form factor: 0.177" diameter circular package, 0.126" maximum height
• Operating voltage range: 2V ~ 10V compatibility
• Impedance: 2.2 kOhms
• Supply current: 500 µA

The TOM-3046L-R qualifies as a substitute based on matching all mechanical and electrical interface parameters. The primary distinction is sensitivity specification: the substitute operates at -46dB ±3dB versus the original -44dB ±3dB, representing a 2dB reduction in output level. Both components maintain identical S/N ratio (60dB), impedance, voltage range, and physical dimensions.

Engineering Selection Recommendations

The TOM-3046L-R is the designated substitute for the obsolete TOM-3044L-R. Selection of this alternative is supported by the following engineering factors:

Product Status: The TOM-3046L-R maintains active product status with current manufacturing availability, ensuring supply chain continuity and long-term component sourcing reliability.

Compliance & Certifications: The TOM-3046L-R is RoHS3 compliant, providing regulatory alignment with current environmental standards. Both components share identical REACH unaffected status and EAR99 export classification.

Electrical & Mechanical Compatibility: The substitute maintains full pin-compatible operation through identical solder pad termination, voltage range (2V ~ 10V), impedance (2.2 kOhms), and supply current (500 µA) specifications. Physical form factor equivalence (0.177" diameter, 0.126" height) ensures direct PCB footprint compatibility.

Sensitivity Consideration: The TOM-3046L-R operates at -46dB ±3dB sensitivity compared to the original -44dB ±3dB specification. This 2dB reduction in output level represents a minor variation within typical analog microphone application tolerances and does not preclude functional substitution in standard audio capture circuits.

Frequently Asked Questions (FAQ)

Q: Can the TOM-3046L-R be used as a direct replacement for the TOM-3044L-R?

A: Yes. The TOM-3046L-R is mechanically and electrically compatible with the TOM-3044L-R. Both components share identical physical dimensions, solder pad termination, voltage range, impedance, and supply current specifications. Direct PCB footprint substitution is supported without circuit modification.

Q: What is the significance of the -2dB sensitivity difference between these components?

A: The TOM-3046L-R operates at -46dB ±3dB sensitivity versus the original -44dB ±3dB.
