Substitute Part Grouping Explanation

Substitution eligibility for the TOM-3046L 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
• Supply voltage range: 2V ~ 10V
• Current consumption: 500 µA
• Termination method: Solder Pads
• Physical dimensions: 0.177" Dia (4.50mm), Height 0.126" (3.20mm)
• Package shape: Circular

The TOM-3046L-R qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction is product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The TOM-3046L-R is the direct substitute for the obsolete TOM-3046L. Both components share identical electrical specifications and mechanical dimensions, ensuring functional compatibility in existing circuit designs.

The TOM-3046L-R offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the TOM-3046L-R achieves ROHS3 compliance, whereas the original TOM-3046L is RoHS non-compliant. This distinction is significant for applications subject to regulatory requirements or procurement policies mandating RoHS compliance.

Both components maintain equivalent moisture sensitivity levels and REACH status. Selection between these parts should be based on regulatory requirements, supply chain considerations, and compliance mandates applicable to the end application.

Frequently Asked Questions (FAQ)

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

A: Yes. The TOM-3046L-R is electrically and mechanically equivalent to the TOM-3046L. All critical parameters—sensitivity, impedance, voltage range, current consumption, and physical dimensions—are identical. The components are pin-compatible and functionally interchangeable.

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

A: The TOM-3046L-R is an active product with ROHS3 compliance, while the TOM-3046L is obsolete and RoHS non-compliant. The TOM-3046L-R also specifies a frequency range of 30 Hz ~ 15 kHz, which is not documented for the original part.

Q: Are there packaging differences between TOM-3046L and TOM-3046L-R?

A: The TOM-3046L-R is supplied in bulk packaging, whereas the original TOM-3046L packaging specification is not detailed in the available data. Both components feature identical solder pad termination and circular form factor.

Q: Does the TOM-3046L-R meet RoHS requirements?

A: Yes. The TOM-3046L-R is ROHS3 compliant. If your application or procurement policy requires RoHS compliance, the TOM-3046L-R is the appropriate selection.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Both components operate at 2V ~ 10V supply voltage, draw 500 µA current, provide -46dB ±3dB sensitivity, maintain 60dB S/N ratio, and present 2.2 kOhms impedance. Electrical performance is equivalent.

Q: What is the physical footprint compatibility?

A: Both parts share identical dimensions: 0.177" diameter (4.50mm) with a maximum height of 0.126" (3.20mm). The circular shape and top-mounted port location are consistent. PCB layout modifications are not required for substitution.
