Is there a pin-compatible replacement for JEN1006-3.3V-ULC?

No replacements have been verified as pin-to-pin compatible. While several candidates use the same DFN1006 package, differences in electrical parameters require a full engineering review before considering them for drop-in replacement.

What risks should I check before replacing JEN1006-3.3V-ULC?

Before replacing, you must verify three key parameters: 1) Capacitance, to ensure it's low enough for your high-speed interface. 2) Peak Pulse Current (Ipp), to ensure it meets the required 10A surge protection. 3) Reverse Working Voltage (VRWM), to ensure it's compatible with your system's 3.3V logic levels.

AI replacement insight

Electrical riskhigh

Capacitance, voltage, and current ratings must be carefully verified to match the application.

Package risklow

Several candidates share the same DFN1006 package, but pinout compatibility is assumed, not verified.

Can it be replaced directly?

No direct, verified drop-in replacement has been identified. Several functional alternates exist but require engineering review due to differences in voltage or missing specifications.

Best replacement path

Verify the peak current rating of ULC candidates like ESD112-B1-02EL or PESDMC2FD5VB.

Main risk

The primary risk is capacitance mismatch, which can degrade signal integrity in high-speed applications. Secondary risks include differences in voltage ratings and unverified surge current capability.

Recommended alternatives

A promising ULC alternate in the same package, but requires review of its higher voltage and missing current spec.
