Substitute Part Grouping Explanation

Substitution in the Diodes, Rectifiers category is determined by strict matching of electrical and mechanical parameters: diode configuration, technology, voltage and current ratings, forward voltage, reverse leakage current, recovery speed, operating temperature, mounting type, and package form factor. Parts must also hold equivalent compliance certifications and product status. Only parts meeting every listed parameter are included as substitutes.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters must be matched for substitution in diode rectifiers?
A: Diode configuration, technology, voltage rating, current rating, forward voltage, reverse leakage current, recovery speed, and junction temperature must be matched.

Q2: Are the packaging and mounting type critical for substitution?
A: Yes, mechanical compatibility including package type (TO-220-3 Full Pack), supplier device package (TO-220FN), and mounting type (Through Hole) are mandatory for substitution.

Q3: Does RoHS and REACH compliance affect engineering selection?
A: Only ROHS3 compliant and REACH unaffected parts can be used as substitutes where such certifications are required for application or regulatory conformity.

Q4: Is it allowed to substitute a diode with a higher current rating?
A: Substitution is permitted when all other electrical and mechanical parameters are strictly matched as specified.

Q5: What product status is required for substitute selection?
A: Only parts with an 'Active' product status are included in the substitute group for ongoing supply assurance.
