Substitute parts are selected only if they exactly match the primary electrical performance metrics and mechanical packaging of the MJD42CJ. The allowed parameters for substitution are:

• Transistor Type (PNP)
• Voltage - Collector Emitter Breakdown (Max) (100 V)
• Current - Collector (Ic) (Max) (6 A)
• Vce Saturation (Max) @ Ib, Ic (1.5V @ 600mA, 6A)
• Current - Collector Cutoff (Max) (1µA)
• DC Current Gain (hFE) (Min) @ Ic, Vce (30 @ 300mA, 4V)
• Power - Max (1.6 W)
• Frequency - Transition (3MHz)
• Operating Temperature (150°C (TJ))
• Mounting Type (Surface Mount)
• Package / Case (TO-252-3, DPAK (2 Leads + Tab), SC-63)
• Supplier Device Package (DPAK)
• RoHS Status (ROHS3 Compliant)
• Moisture Sensitivity Level (MSL)
• REACH Status
• Product Status

Any substitute listed satisfies all these parameter matches.
