Substitute Part Grouping Explanation

Substitution is determined by strict matching of electrical characteristics, mechanical dimensions, and compliance attributes. Substitute parts in this category must have identical values for technology (Schottky), maximum DC reverse voltage (80 V), average rectified current (8A), forward voltage drop (720 mV @ 8A), reverse leakage current (550 µA @ 80 V), capacitance (500pF @ 5V, 1MHz), surface mount package (TO-263AB/D2PAK), automotive qualification (AEC-Q101), and full RoHS3 and REACH compliance. Package and base part number alignment are also required.

Parameter Comparison

Engineering Selection Recommendations

Selection between VS-8TQ080STRRHM3 and VS-8TQ080S-M3 can be based on product status (Active), certification standards (AEC-Q101 automotive qualification, ROHS3 compliance, REACH unaffected), and inventory availability. Both models maintain equivalent status on all compliance and environmental metrics as specified in the provided data.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters are required to ensure substitution compatibility between Schottky rectifier diodes?
A1: The key parameters are technology type (Schottky), voltage rating (80 V), current rating (8A), forward voltage (720 mV @ 8A), reverse leakage current (550 µA @ 80 V), and capacitance (500pF @ 5V, 1MHz).

Q2: Are there any differences in the package or mounting style for VS-8TQ080STRRHM3 and its substitute VS-8TQ080S-M3?
A2: Both parts use the TO-263AB (D2PAK) surface mount package with identical case and mounting type.

Q3: How important is compliance certification when selecting between the main part and its substitute?
A3: Compliance certifications such as ROHS3, REACH, and AEC-Q101 automotive qualification are critical and must match for substitute acceptance in regulated and automotive applications.

Q4: Does the substitute part offer equivalent performance under the same operating conditions?
A4: Both VS-8TQ080STRRHM3 and VS-8TQ080S-M3 specify identical operating temperature ranges (-55°C ~ 175°C) and electrical characteristics.
