Engineering Selection Recommendations

First Choice: EKZE6R3ELL331MF11D

This Chemi-Con part is the direct parametric equivalent to the KZE6.3VB331M6X11LL. It maintains identical electrical and mechanical specifications, including capacitance, voltage rating, tolerance, lifetime rating, impedance, and physical dimensions. The part is currently active in production and ROHS3 compliant, making it the optimal choice for direct replacement in existing designs or new applications requiring the original specification.

Alternative Choice: EEU-FM0J331

The Panasonic EEU-FM0J331 meets all core electrical compatibility requirements and is currently active. This part offers higher ripple current capability (318.5 mA @ 120 Hz and 455 mA @ 100 kHz) compared to the original specification. The height dimension is 0.500" (12.70 mm), exceeding the original 0.433" (11.00 mm). PCB layout clearance must be verified before selection.

Extended Lifetime Option: UHE0J331MED

The Nichicon UHE0J331MED provides double the lifetime rating (4000 hours at 105°C versus 2000 hours), offering enhanced reliability for applications requiring extended operational life. All core electrical and mechanical parameters match the original specification. This part is currently obsolete but remains available in inventory.

Extended Temperature Range Options: SEK331M6R3ST and UPW0J331MED

Both the Cornell Dubilier SEK331M6R3ST and Nichicon UPW0J331MED support extended operating temperature range (-55°C to 105°C versus -40°C to 105°C). These parts are suitable for applications requiring operation at lower temperatures. The SEK331M6R3ST has a slightly increased height of 0.453" (11.50 mm). Both parts are currently obsolete.
