Equivalent & Substitute Parts Reference: UES1306E3

Part Overview

The UES1306E3 by Microchip Technology is a general purpose diode used for rectification applications. It features a maximum reverse DC voltage of 400V, an average rectified current of 3A, and fast recovery characteristics. This component is actively supplied in bulk packaging, with a through-hole B axial configuration. Sourcing equivalent or substitute diodes is essential for maintaining supply chain resilience and ensuring uninterrupted production, especially given inventory constraints or possible compliance requirements.

Substitute Part Grouping Explanation

Substitution is determined strictly by matching all defined key parameters: voltage rating (400 V maximum reverse voltage), average rectified current rating (3A), maximum forward voltage drop (1.25 V at 3A), fast recovery speed (50 ns), reverse leakage current (20 µA @ 400 V), mounting type (through-hole, B axial), operating temperature range (-55°C ~ 150°C), product status, and relevant compliance documentation (REACH status, ECCN, HTSUS code). Only parts identical on these metrics are considered as parametric equivalents in this product category (diodes, rectifiers).

Engineering Selection Recommendations

Both UES1306E3 and UES1306 are active products with identical electrical and mechanical characteristics, and both are listed as REACH unaffected and EAR99 for ECCN classification. Selection between these two should be guided by inventory availability, packaging, and the compliance status required by the application. RoHS compliance for UES1306 is listed as non-compliant, while UES1306E3 provides only REACH status. Only select alternatives that strictly match the compliance and certification documentation specified in your project or procurement requirements.

Frequently Asked Questions (FAQ)

Q1: What criteria must be met for a diode to be considered a substitute for UES1306E3?
A1: The substitute diode must match all specified electrical ratings (400 V Vr, 3A Io, 1.25 V Vf @ 3A), speed (Fast recovery ≤ 500ns, >200mA), reverse recovery time (50 ns), leakage current (20 µA @ 400 V), mounting type (Through Hole), package/case (B axial), operating temperature (-55°C to 150°C), product status (Active), and compliance attributes.

Q2: Are the package and mounting type critical when selecting substitutes?
A2: Yes, only substitutes with matching through-hole mounting and B axial package/case are suitable to ensure mechanical compatibility.

Q3: Does compliance documentation affect substitute selection?
A3: Substitute selection must comply with specified REACH status, ECCN, and HTSUS codes. RoHS compliance should also be verified if required by the application.

Q4: Can substitutes from the same manufacturer be used without further assessment?
A4: Only if all specified parameters and documentation match exactly. Manufacturer alone is not a sufficient criterion for substitution.

Q5: How does inventory availability impact part selection?
A5: Inventory levels affect procurement decisions. Use substitutes with identical parameters and compliance when required quantities of the main part are not available.
