Is there a pin-compatible replacement for 1010500812R00?

Several candidates share the same radial 8x12mm package, but none are confirmed pin-to-pin functional equivalents without review. Critical electrical parameters like ESR and ripple current differ significantly.

What risks should I check before replacing 1010500812R00?

Verify the replacement's ESR, ripple current rating, and operating temperature range. The target is a high-performance polymer capacitor; using a standard electrolytic type is a major downgrade risk.

1010500812R00 Alternatives, Datasheet & Cross Reference | NJCON

Finding a substitute for the NJCON 1010500812R00, a 100uF 50V solid polymer capacitor, requires careful matching of its low ESR and high ripple current. Alternatives exist but may differ in performance.

AI replacement insight

Electrical riskhigh

Major differences in ESR and ripple current.

Package risklow

Most candidates match the radial package.

Can it be replaced directly?

No direct, drop-in replacement has been identified. All candidates require engineering review due to significant differences in ripple current, ESR, or capacitor technology.

Best replacement path

Find another solid polymer capacitor with ESR ≤ 35mΩ and ripple current ≥ 2800mA. KNSCHA KNH4100UF50V149EC0024 is a polymer type but has lower performance.

Main risk

The primary risk is substituting a capacitor with much lower ripple current handling, which can cause overheating and premature failure in power applications.

Recommended alternatives

Same package and basic ratings, but has much lower ripple current and slightly higher ESR.
