Key Parameters

Substitute Part Grouping Explanation

Substitution within the Diodes, Rectifiers category requires strict electrical and mechanical equivalence. The allowed parameters for substitution are: maximum reverse voltage, average rectified current, maximum forward voltage at current, recovery speed, reverse recovery time, reverse leakage current, package type, supplier device package, operating temperature range, RoHS status, MSL, and regulatory compliance.

Only manufacturer part numbers matching these parameters can be considered for direct substitution. Substitutes are listed when all relevant parameters align precisely with the main part.

Parameter Comparison

Engineering Selection Recommendations

Both SJPL-F4 and SJPL-F4VR are active products and conform to industry standards for environmental compliance, including RoHS and MSL 1 (Unlimited). Regulatory designations (ECCN and HTSUS) are identical. Selection between these two is permitted based on part status and compliance documentation provided.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for direct substitution of diodes in the rectifiers category?
A1: Parameters include maximum DC reverse voltage, average rectified current, maximum forward voltage at rated current, reverse recovery time, reverse leakage current, speed classification, operating temperature, package/case, and compliance status.

Q2: Are SJPL-F4 and SJPL-F4VR mechanically identical for PCB assembly?
A2: Both diodes use the same 2-SMD, J-Lead package and SJP supplier device package, providing equivalent mechanical compatibility.

Q3: Does RoHS or MSL status affect substitution choices?
A3: Both SJPL-F4 and SJPL-F4VR are RoHS compliant and designated as MSL 1, allowing unlimited moisture exposure before reflow and supporting direct substitution.

Q4: Is there any difference in electrical performance between SJPL-F4 and SJPL-F4VR?
A4: No difference is present in DC reverse voltage, average rectified current, forward voltage at rated current, reverse recovery time, reverse leakage current, or speed.
