Direct Equivalent (380LX103M016J012): Maintains identical electrical specifications including 75 mOhm ESR @ 120Hz and 3000-hour lifetime @ 85°C. Physical dimensions and lead spacing are identical. This part is manufactured by Cornell Dubilier Electronics and is in active production status.

Upgraded Performance (381LX103M016J012, LGU1C103MELA, LGY1C103MELA25): These parts maintain the same capacitance, voltage rating, tolerance, and physical dimensions. They offer extended operating temperature range (-40°C ~ 105°C) and longer lifetime ratings (3000 or 5000 hours @ 105°C). These upgrades provide improved thermal performance while maintaining mechanical compatibility.

Similar Specification (SLP103M016C1P3, SLPX103M016A3P3): These parts share the same capacitance, voltage, tolerance, and lead spacing. They feature lower ESR values (66 mOhm @ 120Hz) and different ripple current ratings. Physical dimensions vary: SLP103M016C1P3 has a height of 0.984" (25.00 mm), and SLPX103M016A3P3 has a diameter of 0.866" (22.00 mm) and height of 1.181" (30.00 mm).

Parametric Equivalent (109LBB016M2CC): Matches core electrical parameters with 66.3 mOhm ESR @ 120Hz and identical physical dimensions to the main part. Manufactured by Cornell Dubilier / Illinois Capacitor.
