Engineering Selection Recommendations

FR203GP-AP is the primary direct equivalent for FR203-AP replacement. Both parts are manufactured by Micro Commercial Co with identical electrical and mechanical specifications. FR203GP-AP holds active product status with 1120 units in stock, compared to the obsolete FR203-AP with 764 units. This part maintains the same DO-15 package configuration and all electrical parameters, including 200 V reverse voltage, 2 A rectified current, 1.3 V forward voltage drop, and 150 ns reverse recovery time. Selection of FR203GP-AP eliminates obsolescence risk while preserving design compatibility.

FR203G and FR203G A0G (Taiwan Semiconductor Corporation) serve as parametric equivalents with active product status. Both parts deliver identical voltage, current, and thermal specifications. The primary distinction is capacitance rating: 10 pF versus 40 pF at 4V, 1MHz. Both parts are ROHS3 compliant and REACH unaffected. FR203G A0G includes additional cross-reference documentation to alternative part numbers. Inventory availability is 725 units (FR203G) and 733 units (FR203G A0G).
