Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching key parameters relevant for the Diodes, Rectifiers category: average rectified current (Io), voltage forward (Vf) at specified test current, recovery speed, mounting type, package/case, supplier device package, operating temperature range, and product status. Compliance parameters such as RoHS and REACH status are also considered to address regulatory requirements. Only parts matching these fields are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Based strictly on the provided product statuses, both R37120 and S85Q are listed as Active components. For applications requiring RoHS compliance, S85Q (GeneSiC Semiconductor) is compliant under ROHS3, whereas R37120 (Microchip Technology) is RoHS non-compliant. Both parts are REACH Unaffected. Electrical and mechanical substitutability is established through their identical category, current rating, and package/case compatibility. The recommended substitute part, S85Q, matches key parameters and fulfills compliance criteria specified in the input.

Frequently Asked Questions (FAQ)

Q1: Which key parameters are used to determine substitute compatibility for Diodes, Rectifiers such as R37120?
A1: Substitution is determined by current rating (Io), forward voltage (Vf) at specified current, recovery speed, mounting type, package/case, supplier device package, and operating temperature range.

Q2: Can S85Q directly replace R37120 in applications requiring stud mount DO-203AB packaging?
A2: S85Q utilizes the DO-203AB, DO-5, stud mount package and matches the mounting type, enabling direct mechanical substitution.

Q3: Are there differences in RoHS compliance status between the main and substitute part?
A3: R37120 is RoHS non-compliant; S85Q is ROHS3 compliant. Selection should be based on compliance requirements for the target application.
