Parametric upgrade (16V, 1.0Ω ESR) but in a larger C-Case package.
Best Alternatives to TAJB107M010RNJ
Finding a replacement for the TAJB107M010RNJ, a 100µF 10V 1210 tantalum capacitor, involves checking key electrical parameters and the physical package. While no direct drop-in replacements were found in this review, several functional alternatives exist that offer upgraded p...
AI replacement insight
Package riskhigh
All candidates have different footprints (A, C, D, E-Case vs B-Case), requiring board redesign.
Electrical risklow
Most candidates are parametric upgrades (higher voltage, lower ESR), which is generally safe but requires verification.
Can it be replaced directly?
No direct, pin-for-pin replacement was identified in this review. All evaluated options have different physical packages.
Best replacement path
Upgrade to a higher voltage/lower ESR part like TAJD107K020RNJ, but this requires a larger PCB footprint (D-case).
Main risk
Physical package mismatch is the primary risk, requiring mandatory PCB redesign for all evaluated alternatives.

Questions & answers
The best alternative depends on your design constraints. For a parametric upgrade in a larger footprint, TAJD107K020RNJ offers higher voltage (20V), tighter tolerance (10%), and lower ESR. If you need an electrically identical part and can modify the layout for a smaller A-case package, TLJA107M010R1400 is a strong candidate.
