Is there a pin-compatible replacement for LZ1V101M-CRE77?

Yes, VT1V101M-CRE77 and 50TZV100M8X10.5 share the same 8mm x 10.5mm package and are considered pin-compatible. However, their electrical performance, specifically ripple current and impedance (ESR), must be verified to ensure they are a suitable functional replacement.

What risks should I check before replacing LZ1V101M-CRE77?

The main risks are electrical. You must check that the replacement's ripple current rating is equal to or greater than the original's 450mA. Also, verify the impedance (ESR) is similarly low to prevent overheating and maintain circuit stability, especially in power supply applications.

Finding a substitute for the LZ1V101M-CRE77 100µF 35V capacitor requires careful attention to its low impedance and high ripple current ratings. While several parts match its size and basic specs, verifying these key performance parameters is critical for ensuring reliability.

AI replacement insight

Electrical riskhigh

Mismatch in ripple current or ESR can cause circuit instability or component failure.

Package risklow

Several candidates match the 8x10.5mm package, ensuring physical compatibility.

Can it be replaced directly?

No direct, verified drop-in replacement has been identified. All candidates require engineering review, primarily for ripple current and impedance (ESR) performance.

Best replacement path

The Rubycon 50TZV100M8X10.5 is a strong candidate due to its higher voltage and known low-impedance series, but only if the application can tolerate a lower ripple current (350mA vs 450mA).

Main risk

The primary risk is substituting with a capacitor that has higher impedance or lower ripple current handling, which can lead to overheating, reduced performance, or failure in power supply applications.

Recommended alternatives

Pin-compatible voltage upgrade, but has a lower ripple current rating that requires application review.
