Substitute Part Grouping Explanation

Substitution eligibility for the A6284KLPTR-T-1 is determined by strict equivalence across the following critical parameters:

• Manufacturer & Base Product: Same manufacturer (Allegro MicroSystems) and base product number (A6284)
• Electrical Specifications: Identical output channel count (6), output current per channel (120mA), supply voltage range (5V to 42V), and dimming method (PWM)
• Package & Mounting: Identical package type (20-TSSOP with exposed pad), mounting method (Surface Mount), and physical dimensions
• Environmental & Compliance: Matching operating temperature range (-40°C to 150°C), automotive grade, AEC-Q100 qualification, ROHS3 compliance, and MSL rating (2)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in packaging suffix (such as -T versus -T-1) indicate different tape and reel configurations or manufacturing date codes but do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The A6284KLPTR-T is a direct parametric equivalent to the A6284KLPTR-T-1. Both parts are manufactured by Allegro MicroSystems, carry identical electrical and mechanical specifications, and maintain active production status. Both devices hold AEC-Q100 automotive qualification and ROHS3 compliance, making them suitable for automotive LED driver applications requiring 6-channel PWM dimming control at 120mA per channel across a 5V to 42V supply range.

Selection between these two part numbers should be based on inventory availability and supply chain requirements. The A6284KLPTR-T currently has higher stock availability (4290 units) compared to the A6284KLPTR-T-1 (1910 units), which may influence procurement decisions for high-volume production runs. Both parts are functionally interchangeable at the circuit level and require no design modifications for substitution.
