Parameter Comparison

Engineering Selection Recommendations

The LLS1C223MELA from Nichicon is a direct parametric equivalent to the 229LBB016M2CF. Both parts are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

Selection Basis:

The substitute part matches all critical electrical and mechanical parameters required for direct board-level substitution. Both capacitors are rated for identical capacitance (22000 µF), voltage (16 V), tolerance (±20%), operating temperature range (-40°C to 85°C), and thermal lifetime (3000 hours at 85°C). Physical compatibility is confirmed through identical lead spacing (10.00 mm), can diameter (25.00 mm), and seated height (42.00 mm), ensuring mechanical fit in existing PCB layouts designed for snap-in radial through-hole mounting.

The LLS1C223MELA demonstrates slightly higher ripple current capability at 120 Hz (4.44 A versus 4.26 A), which represents an operational advantage in applications subject to AC ripple stress. Both parts maintain polar orientation and are suitable for general-purpose energy storage and filtering applications.
