Key Parameters

Substitute Part Grouping Explanation

Equivalent and substitute diode selections for RFN5B2STL are strictly based on matching the following provided parameters: part category (Diodes, Rectifiers), current rating (5A), maximum forward voltage (980 mV @ 5 A), speed classification (Fast Recovery ≤ 500ns, >200mA), reverse recovery time (25 ns), reverse leakage current (10 µA @ 200 V), surface mount mounting, and physical package (TO-252-3/DPAK/SC-63 or equivalent). Compliance attributes (RoHS, MSL, ECCN, HTSUS) and operating temperature (150°C) are also matched where provided.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute rectifiers for RFN5B2STL is based on the product status being listed as Obsolete. Substitute parts such as RFN5BM2STL are Active, ROHS3 Compliant, and share identical values for current rating, forward voltage, speed, reverse recovery time, reverse leakage, mounting type, package, and compliance. Moisture Sensitivity Level (MSL) and ECCN codes also match the main part.

Frequently Asked Questions (FAQ)

Q1: What parameters must be matched to substitute RFN5B2STL?
A1: Substitute diodes must match current rating, maximum forward voltage, speed classification, reverse recovery time, reverse leakage, package type, mounting method, operating temperature, and compliance attributes.

Q2: Is the package type critical for diode substitution?
A2: Yes. RFN5B2STL uses the TO-252-3, DPAK (2 Leads + Tab), SC-63 Surface Mount package. Substitute parts must use the same package to ensure mechanical and electrical compatibility in assemblies.

Q3: Are there differences in compliance or certification among substitutes?
A3: Substitute parts listed (e.g., RFN5BM2STL) are ROHS3 Compliant and have MSL 1 (Unlimited), matching the required attributes for direct substitution.

Q4: Why is substitution necessary for RFN5B2STL?
A4: The part is Obsolete. Approved substitutes secure supply chain continuity and allow maintenance or production without design changes.

Q5: Does the substitution affect performance or reliability?
A5: Strict parameter matching ensures electrical and mechanical equivalence, so performance remains as specified by the matched key parameters.
