Is there a pin-compatible replacement for TPD2E007DCKR?

PESD15VS2UT shares the SOT-23 package and pinout. However, its I/O capacitance is 90pF, far exceeding the target's 15pF, making it unsuitable for high-speed data lines without verification.

What risks should I check before replacing TPD2E007DCKR?

Key risks are pinout mismatch, which requires a PCB redesign, and I/O capacitance, where a higher value can disrupt signal integrity. Also verify the working voltage (VRWM) and clamping voltage provide adequate protection for your circuit.

TPD2E007DCKR Alternatives, Datasheet & Cross Reference | Leiditech

TPD2E007DCKR is a 2-channel ESD protection diode for data lines in a SOT-23 package. Finding a direct drop-in replacement requires careful matching of pinout, voltage, and I/O capacitance.

AI replacement insight

Electrical riskhigh

High capacitance or wrong pinout are critical electrical risks.

Package risklow

SOT-23 is a standard package, but pinout must be verified.

Can it be replaced directly?

No direct, risk-free replacement has been identified. All candidates have critical differences in pinout or key electrical parameters like capacitance.

Best replacement path

No ideal path; requires engineering review. PESD15VS2UT is pin-compatible but has high capacitance. TPESD15BS3 is functional but needs a board spin.

Main risk

The main risks are pinout incompatibility requiring board changes, and high I/O capacitance degrading signal integrity.

Recommended alternatives

Pin-compatible package, but critically higher I/O capacitance makes it unsuitable for most data lines.
