Equivalent & Substitute Parts Reference for EM2B – Sanken Electric USA Inc.

Part Overview

The EM2B (Manufacturer Part Number: EM2B, Sanken Electric USA Inc.) is an active general-purpose diode with the following critical features: 800 V maximum DC reverse voltage, 1.2A average rectified current, and a standard recovery speed, provided in an axial through-hole package. When working on designs or repairs, it is essential to identify equivalent and substitute diode models due to inventory variation, procurement needs, or to meet compliance requirements. Substitutes must strictly meet or exceed all critical electrical and mechanical parameters specified for EM2B in the "Diodes, Rectifiers" category.

Substitute Part Grouping Explanation

Substitute parts for the EM2B diode are identified by strict comparison of the following provided parameters: "Voltage - DC Reverse (Vr) (Max)", "Current - Average Rectified (Io)", "Voltage - Forward (Vf) (Max)", "Speed", "Current - Reverse Leakage @ Vr", "Mounting Type", "Package / Case", "Operating Temperature - Junction", and compliance status ("RoHS", "MSL", "ECCN", "HTSUS"). All listed substitutes are in the "Diodes, Rectifiers" category and meet or exceed these key requirements based on direct data.

Engineering Selection Recommendations

All listed substitute part numbers share an active product status and conform to the required RoHS compliance and MSL rating (1 – Unlimited). The substitute diodes also retain the same essential customs export designation (EAR99) and harmonized tariff schedule code (8541.10.0080), matching the regulatory and inventory requirements for direct selection in engineering applications within the Diodes, Rectifiers category.

Frequently Asked Questions (FAQ)

Q1: Which key parameters must be matched for substitution in the Diodes, Rectifiers category?
A1: Substitution requires strict matching or exceeding of the following: maximum DC reverse voltage, average rectified current, forward voltage at specified current, recovery speed, reverse leakage current, mounting type, and operating temperature range, along with compliance and mechanical packaging specifications.

Q2: Are all substitute diodes listed suitable for through-hole mounting in axial packages?
A2: Yes, all substitutes are specified for through-hole mounting with axial packages or standard diode outlines suitable for direct replacement.

Q3: How does RoHS status influence substitute selection for EM2B?
A3: All parts, including EM2B and its substitutes, are RoHS compliant, ensuring conformance to environmental and material safety regulations for procurement and application.

Q4: Can differences in recovery speed affect substitution decisions?
A4: Only specified speed values are considered. Substitutes provided match or exceed the application criteria for recovery speed as specified in the input.

Q5: Why is inventory availability noted for each substitute part?
A5: Inventory status is listed to indicate current sourcing options, but is not a technical substitution criterion.

Q6: Are there differences in temperature rating among substitute parts?
A6: Substitute parts meet or exceed the specified operating temperature range required for EM2B. Only the input-supplied data is used for parameter match.
