Is there a pin-compatible replacement for ACT45C-510-2P-TL000?

WBA4532L510T-G-HF shares the same 1812 package, making it physically compatible. However, its lower temperature rating (85°C vs 125°C) and lack of AEC-Q200 rating mean it is not a direct drop-in for automotive applications and requires careful review.

What risks should I check before replacing ACT45C-510-2P-TL000?

Key risks include: 1) Operating Temperature: Ensure the replacement meets your system's thermal requirements. 2) AEC-Q200 Compliance: Critical for automotive use. 3) Electrical Parameters: Verify that any differences in inductance, impedance, DCR, and current rating are acceptable for your circuit's performance.

ACT45C-510-2P-TL000 Alternatives, Datasheet & Cross Reference | TDK Electronics AG

The TDK ACT45C-510-2P-TL000 is an AEC-Q200 qualified common mode choke in an 1812 package for CAN-BUS. Finding a direct replacement requires matching its 51µH inductance, 200mA current rating, and wide -40 to +125°C temperature range.

AI replacement insight

Electrical riskmedium

Candidates have different current, temperature, or inductance values requiring verification.

Package risklow

Several candidates match the 1812 package, making them physically compatible.

Can it be replaced directly?

No direct, fully-equivalent drop-in replacement was found. All candidates have tradeoffs in temperature, AEC-Q200 rating, or key electrical parameters.

Best replacement path

For non-automotive use, review WBA4532L510T-G-HF. For automotive, re-evaluate the circuit with another ACT45C series part, accepting different electricals.

Main risk

The main risk is matching both the electrical specifications and the automotive-grade (AEC-Q200, 125°C) qualifications of the original part.

Recommended alternatives

Matches key electricals like inductance and DCR but has a lower temperature rating and is not for automotive use.
