Substitute Part Grouping Explanation

Substitution of the TM-24568-000 is determined by strict equivalence across the following critical parameters:

• Microphone Type: Electret Condenser technology
• Output Configuration: Analog output
• Directional Pattern: Omnidirectional
• Frequency Response: 100 Hz ~ 5.8 kHz
• Sensitivity: -56dB ±3dB @ 74dB SPL
• Electrical Specifications: 4.4 kOhms impedance, 0.9 V ~ 1.6 V operating range, 50 µA supply current
• Physical Interface: Solder pad termination
• Package Footprint: 0.141" x 0.141" (4.67mm x 4.67mm) base dimensions

The TO-24611-000 meets all substitution criteria, maintaining identical electrical and functional specifications while differing only in series designation, product status, packaging format, and physical height.

Engineering Selection Recommendations

The TO-24611-000 serves as the direct functional equivalent for the obsolete TM-24568-000. Selection of the TO-24611-000 is supported by the following factors:

• Active Product Status: The TO-24611-000 maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: The TO-24611-000 is ROHS3 compliant, meeting current environmental and regulatory requirements.
• Electrical Equivalence: All critical electrical parameters, frequency response, sensitivity, and impedance specifications are identical.
• Physical Compatibility: Identical footprint and solder pad termination enable direct PCB layout compatibility.
• Height Consideration: The TO-24611-000 exhibits a reduced maximum height of 0.053" (1.35mm) compared to 0.070" (1.77mm) for the TM-24568-000. This dimensional difference must be evaluated against specific application space constraints and PCB assembly clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can the TO-24611-000 be used as a direct replacement for the TM-24568-000?

A: Yes. The TO-24611-000 is electrically and functionally equivalent across all specified parameters including frequency response, sensitivity, impedance, voltage range, and current consumption. Both components share identical solder pad termination and footprint dimensions.

Q: What is the significance of the height difference between these parts?

A: The TO-24611-000 has a maximum height of 0.053" (1.35mm) versus 0.070" (1.77mm) for the TM-24568-000. This 0.017" (0.42mm) reduction must be evaluated within the context of your specific PCB assembly design, component stacking requirements, and enclosure clearance specifications.

Q: Why is the TM-24568-000 classified as obsolete?

A: The TM-24568-000 has reached end-of-life status. The TO-24611-000 represents the active production equivalent and is the recommended selection for new designs and ongoing production requirements.

Q: Are there compliance differences between these parts?

A: The TO-24611-000 is ROHS3 compliant and carries a Moisture Sensitivity Level rating of 1 (Unlimited). The TM-24568-000 specifications do not include these designations. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Q: What packaging formats are available?

A: The TM-24568-000 packaging format is not specified. The TO-24611-000 is supplied in Tray packaging. Confirm packaging requirements with your procurement specifications.

Q: Are the electrical characteristics identical?

A: Yes. Both components operate at 0.9 V ~ 1.6 V with 50 µA supply current, maintain 4.4 kOhms impedance, and deliver -56dB ±3dB sensitivity at 74dB SPL across the 100 Hz ~ 5.8 kHz frequency range.
