Key Parameters

Substitute Part Grouping Explanation

For the Diodes, Rectifiers product category, the selection of a functional equivalent requires strict adherence to critical parameters: Schottky technology, a maximum reverse voltage of 20 V, similar average rectified current, maximum forward voltage at specified test current, recovery speed classification, reverse leakage at maximum voltage, and identical mounting and package format (through-hole DO-41). Substitute devices meeting these criteria are included.

Parameter Comparison

Engineering Selection Recommendations

The SR202-AP is designated Not For New Designs. The direct substitute 1N5817G from Microchip Technology is active, and both parts share compliance attributes including REACH Unaffected status, ECCN EAR99, and the same HTSUS code. The product category and package type are consistent between the main and substitute parts.

Frequently Asked Questions (FAQ)

Q1: What are the main considerations when substituting Schottky rectifier diodes?

A1: Substitution is based on technology (Schottky), maximum DC reverse voltage, average rectified current, forward voltage characteristics, reverse leakage current, speed classification, and package compatibility.

Q2: Are the SR202-AP and 1N5817G mechanically compatible?

A2: Both diodes use the DO-41 axial through-hole package, ensuring suitable mechanical interchangeability for compatible board layouts.

Q3: Do these diodes comply with the same certification and regulatory standards?

A3: Both parts are classified as REACH Unaffected, with ECCN EAR99 and HTSUS 8541.10.0080, ensuring equivalent compliance within their category.

Q4: Is current rating a critical selection criterion in this substitution group?

A4: Yes, average rectified current is a primary parameter; confirm values match system requirements based on the parameters provided.

Q5: Why is the SR202-AP not recommended for new designs?

A5: Its product status is listed as Not For New Designs. This status directly informs the need to identify substitute parts for ongoing or future designs.
