Engineering Selection Recommendations

Primary Substitute: MAX4452EXK+T

The MAX4452EXK+T is the direct functional equivalent of the MAX4452EXK-T. All electrical parameters, mechanical dimensions, and pin configurations are identical. The substitute part is currently in active production status, ensuring long-term availability and supply chain stability.

Compliance Advantage:

The MAX4452EXK+T carries ROHS3 compliance certification, whereas the original MAX4452EXK-T is RoHS non-compliant. For applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance, the MAX4452EXK+T is the appropriate selection.

Packaging Consideration:

The MAX4452EXK+T is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The original MAX4452EXK-T packaging format is not specified in the provided data. For high-volume production environments, the Tape & Reel format offers handling and placement efficiency advantages.

Supply Status:

With 1424 pieces in current inventory, the MAX4452EXK+T demonstrates active market availability. The obsolete status of the MAX4452EXK-T makes the substitute the recommended selection for new designs and ongoing production support.

Frequently Asked Questions (FAQ)

Q: Can MAX4452EXK+T replace MAX4452EXK-T in existing designs?

A: Yes. The MAX4452EXK+T is electrically and mechanically equivalent. All electrical specifications, operating ranges, and pin configurations are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between MAX4452EXK-T and MAX4452EXK+T?

A: The parts are functionally identical. Differences exist in product status (obsolete versus active), RoHS compliance (non-compliant versus ROHS3 compliant), and packaging format (unspecified versus Tape & Reel). The "+T" designation indicates Tape & Reel packaging.

Q: Is the SC-70-5 package footprint identical between both parts?

A: Yes. Both parts use the 5-TSSOP (SC-70-5, SOT-353) surface mount package. PCB footprints and land patterns are identical, enabling direct board-level substitution.

Q: Does the MAX4452EXK+T meet RoHS requirements?

A: Yes. The MAX4452EXK+T is ROHS3 compliant. The original MAX4452EXK-T is RoHS non-compliant. For applications requiring RoHS certification, the substitute part satisfies regulatory requirements.

Q: Are there any performance differences in bandwidth or slew rate?

A: No. Both parts deliver identical -3dB bandwidth of 200 MHz and slew rate of 95 V/µs. Signal conditioning performance is equivalent across all specified frequency and transient response parameters.
