Is there a pin-compatible replacement for TAJB107M006RNJ?

Yes, both TAJB107K006RNJ and TAJB107M010RNJ are pin-compatible replacements. They share the same 3528 (1210) package and 2-pin layout, allowing them to be used on the same PCB footprint without modification.

What risks should I check before replacing TAJB107M006RNJ?

The main risk is selecting a part with a different package size, which would require a PCB redesign. If choosing a pin-compatible option, confirm that any changes in ESR or tolerance are acceptable for your specific circuit's performance and stability.

AI replacement insight

Package riskhigh

Several candidates have different package sizes (1206, 2917) and are not drop-in compatible.

Electrical risklow

Most candidates offer matching or superior electrical specs (voltage, tolerance, ESR). Verify ESR changes for circuit stability.

Sourcing risklow

The TAJ series from Kyocera AVX is widely available from multiple distributors.

Can it be replaced directly?

Yes, TAJB107K006RNJ is an excellent pin-compatible replacement. It matches the 1210 package, 100µF capacitance, and 6.3V rating, while offering a better 10% tolerance. TAJB107M010RNJ is also a great option with a higher 10V rating.

Best replacement path

The best replacements are TAJB107K006RNJ and TAJB107M010RNJ. Both are in the same 1210 package and offer upgraded performance (tighter tolerance or higher voltage), making them excellent low-risk substitutes.

Main risk

The primary risk when substituting is package mismatch. Several functional alternatives exist in different package sizes (e.g., 1206, 2917) which require PCB layout changes and are not drop-in replacements.

Recommended alternatives

A pin-compatible replacement with identical key specs and a tighter 10% tolerance.
