Substitute Part Grouping Explanation

Substitution is determined strictly by matching electrical and mechanical parameters. Key parameters include DC reverse voltage, average rectified current, forward voltage at rated current, recovery speed, reverse leakage current, mounting type, package, and product status. Compliance statuses such as RoHS and operating temperature values are also considered. Substitute parts must closely align with these values to ensure compatibility and functional equivalence within the Diodes, Rectifiers category.

Engineering Selection Recommendations

Key selection criteria for substitute parts include product status (Active, Last Time Buy, Not for New Designs), RoHS and REACH compliance, and Moisture Sensitivity Level (MSL). Substitute parts S5GC-13-F, S5GL-TP, MURS340T3G, and STTH3R04S are RoHS compliant, while the main part UFS540J/TR13 is not. Product status must be evaluated to match lifecycle requirements; S5GL-TP is not for new designs, ACGRCT302-HF is last time buy. Mounting type and package are matched for all listed substitutes.

Frequently Asked Questions (FAQ)

Q1: What are the essential substitution criteria for UFS540J/TR13?
A1: Substitutes are determined based on DC reverse voltage, average rectified current, forward voltage at rated current, recovery speed, reverse leakage, mounting type, package/case, operating temperature, product status, RoHS compliance, and MSL.

Q2: Are all substitute diodes in identical packages?
A2: All listed substitutes use surface mount packaging compatible with DO-214AB, SMC, or 3220/DO-214AB as specified.

Q3: How does RoHS compliance affect selection?
A3: UFS540J/TR13 is RoHS non-compliant. Substitute parts S5GC-13-F, S5GL-TP, MURS340T3G, ACGRCT302-HF, and STTH3R04S are ROHS3 compliant.

Q4: Is it necessary to match the exact average rectified current?
A4: Average rectified current must be considered for functional equivalence. Substitute parts with 3A or 5A ratings are listed according to the provided data.

Q5: What is the relevance of product status in substitute selection?
A5: Product status such as Active, Last Time Buy, or Not For New Designs determines lifecycle suitability for ongoing production or legacy repairs.
