Substitute Part Grouping Explanation

Substitution is determined by exact matching or exceeding of the following key parameters:

Diode configuration (1 pair common cathode)
Technology (Schottky)
Maximum DC reverse voltage (30 V)
Average rectified current per diode (≥15A)
Package / case type (TO-263-3, D2PAK (2 Leads + Tab), TO-263AB)
Mounting type (Surface Mount)
Speed classification (Fast Recovery ≤ 500ns)
Reverse leakage current (compare as specified)
Maximum operating junction temperature

Substitute parts listed share identical or higher performance within these parameter limits.

Engineering Selection Recommendations

The MBRB3030CT-TP is listed as "Not For New Designs" while the substitute STPS41L30CG-TR is "Active" and ROHS3 compliant. Both parts are REACH unaffected and have an ECCN of EAR99. Use only parts with the appropriate product status and required compliance certifications for regulated designs.

Frequently Asked Questions (FAQ)

Q: What must be matched when substituting a Schottky rectifier such as MBRB3030CT-TP?
A: Match diode configuration, technology, voltage rating, current rating, package type, mounting style, speed, and maximum operating temperature.

Q: Is package compatibility required for substitution?
A: Yes, the replacement part must use TO-263-3, D2PAK (2 Leads + Tab), TO-263AB and be suitable for surface mount applications.

Q: Can a replacement exceed, but not fall below, the main part's current rating?
A: Substitute parts must have current ratings equal to or greater than the main part’s specified value.

Q: Are compliance statuses relevant for substitution?
A: Yes, matching or exceeding compliance requirements such as ROHS and REACH is necessary for regulated environments.

Q: What differences exist between MBRB3030CT-TP and STPS41L30CG-TR?
A: STPS41L30CG-TR offers a higher average rectified current per diode and a lower voltage-forward drop at its maximum current rating.
