Substitute Part Grouping Explanation

Substitution of the BSP321PL6327HTSA1 is determined by strict electrical and mechanical parameter matching. The primary substitute identified is the BSP321PH6327XTSA1, which maintains identical electrical specifications across all critical parameters: P-Channel topology, 100V Vdss rating, 980mA continuous drain current, 900mOhm Rds On, gate threshold voltage, gate charge, and operating temperature range.

The substitution is valid based on the following key parameters:

FET Type: Both devices are P-Channel MOSFETs
Drain to Source Voltage (Vdss): Both rated at 100V
Continuous Drain Current (Id): Both rated at 980mA @ 25°C
On-State Resistance (Rds On): Both 900mOhm @ 980mA, 10V
Gate Threshold Voltage (Vgs(th)): Both 4V @ 380µA
Gate Charge (Qg): Both 12nC @ 10V
Maximum Gate Voltage (Vgs): Both ±20V
Input Capacitance (Ciss): Both 319pF @ 25V
Power Dissipation: Both 1.8W (Ta)
Operating Temperature: Both -55°C to 150°C (TJ)
Mounting Type: Both Surface Mount
Package: Both TO-261-4, TO-261AA

The BSP321PH6327XTSA1 differs only in packaging format (Cut Tape & Digi-Reel) and RoHS compliance status, with no impact on electrical or mechanical compatibility.
