Equivalent & Substitute Parts Reference: FR30B02

Part Overview

The FR30B02 is a diode rectifier from GeneSiC Semiconductor, intended for general-purpose fast recovery applications. It features a stud mount DO-5 package and is actively supported in inventory. The typical reasons for seeking substitute or equivalent models include supply continuity, matching mechanical mounting, or ensuring electrical compatibility in new or existing designs within the Diodes, Rectifiers category.

Substitute Part Grouping Explanation

Substitute parts for the FR30B02 are identified strictly by matching parameters within these categories: package type and mounting format (DO-203AB, DO-5, Stud), electrical ratings (voltage reverse, current average rectified, forward voltage drop, reverse recovery time), product status, compliance designations, and moisture sensitivity level. Only parts meeting these parameters are considered for direct substitution within the Diodes, Rectifiers product group.

Key confirmed substitution criteria:

Stud mount DO-5 (DO-203AB) mechanical compatibility
Maximum DC reverse voltage rating
Average rectified current rating
Forward voltage drop @ specified current
Reverse recovery time
Product/environmental compliance

Engineering Selection Recommendations

Both FR30B02 and VS-1N1184 are active, RoHS compliant, and classified under ECCN EAR99 with a moisture sensitivity level of 1 (unlimited). For design-in or replacement within the Diodes, Rectifiers category, selection may proceed based on these compliance and certification parameters.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for substituting FR30B02 in a design?
A: Voltage - DC reverse rating, average rectified current, and forward voltage drop at operational current are essential. Mechanical mounting type and package must also match.

Q: Is the VS-1N1184 in the same mechanical package as the FR30B02?
A: Both parts use the DO-203AB (DO-5, Stud) package and support chassis, stud mount installation.

Q: Are there differences in environmental compliance between FR30B02 and VS-1N1184?
A: Both are RoHS compliant and classified with ECCN EAR99. VS-1N1184 specifies ROHS3 compliance and is REACH unaffected.

Q: Does the moisture sensitivity level affect the substitution between these two rectifiers?
A: Both parts have MSL 1, supporting unlimited floor life, so moisture sensitivity does not restrict substitution.

Q: Which parameters are critical for physical compatibility when replacing the main part?
A: The package/case type (DO-203AB, DO-5, Stud) and mounting type (stud mount) are critical for mechanical compatibility.
