Substitute Part Grouping Explanation

Substitution eligibility for the BTS452RXT is determined by strict alignment with the following electrical and mechanical parameters:

• Output configuration (High Side N-Channel)
• Switching ratio (1:1)
• Maximum output current (1.8A)
• Load voltage range (6V ~ 52V)
• On-resistance (150mOhm typical)
• Package type (TO-252-5 / DPAK)
• Automotive grade qualification (AEC-Q100)
• Operating temperature range (-40°C ~ 150°C)

The BTS452RATMA1 meets all these criteria and is classified as a parametric equivalent. This part maintains identical electrical specifications and package configuration while offering active product status and improved supply availability.
