Equivalent & Substitute Parts for EDF1DM/45 Bridge Rectifier

Part Overview

The EDF1DM/45 from Vishay General Semiconductor - Diodes Division is a single-phase bridge rectifier with a 200 V peak reverse voltage and a 1 A average rectified current. With standard technology, through-hole mounting in a 4-EDIP (0.300", 7.62mm) package, and a forward voltage of 1.05 V at 1 A, it is suited for general rectification applications. The product is currently obsolete, which creates the need to identify direct alternatives with matching electrical and mechanical specifications for ongoing maintenance, repair, or new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for bridge rectifiers must match the original in terms of diode type (single phase), technology (standard), peak reverse voltage, current rating, forward voltage, reverse leakage current, operating temperature range, mounting type, and package/case dimensions. All listed substitutes comply with these main electrical and mechanical requirements as provided in the input.

Key parameters for substitution:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max)
• Current - Average Rectified (Io)
• Voltage - Forward (Vf) (Max) @ If
• Current - Reverse Leakage @ Vr
• Operating Temperature
• Mounting Type
• Package / Case
• RoHS and REACH compliance
• MSL (Moisture Sensitivity Level)
• ECCN, HTSUS codes

Parameter Comparison

Engineering Selection Recommendations

Based on the obsolete status of Vishay General Semiconductor - Diodes Division EDF1DM/45, only parts with active product status, matching RoHS3 and REACH certifications, and equivalent ECCN and HTSUS classifications are eligible for substitution. EDF1DM-E3/45 from the same manufacturer is an active part with identical electrical and mechanical specifications. DF202-G from Comchip Technology is also active and shares compliance status and device package format as defined in the parameters.

Frequently Asked Questions (FAQ)

Q1: Which key parameters determine interchangeability in single-phase bridge rectifiers like EDF1DM/45?
A1: Interchangeability is defined by diode type, technology, voltage rating, current rating, forward voltage, reverse leakage current, operating temperature, mounting type, package/case, and compliance with RoHS and REACH.

Q2: What are the package differences among the substitutes?
A2: EDF1DM/45 and EDF1DM-E3/45 use the 4-EDIP (0.300", 7.62mm) package with supplier device code DFM. DF202-G uses a slightly larger 4-EDIP (0.321", 8.15mm) package with supplier device code 4-DF.

Q3: Is the substitute's forward voltage or current significantly different?
A3: EDF1DM-E3/45 matches both forward voltage and current ratings. DF202-G provides a higher average rectified current (2 A vs. 1 A) and a slightly higher forward voltage (1.1 V @ 2 A).

Q4: What compliance certifications are confirmed for compatible substitutes?
A4: All listed substitutes are ROHS3 compliant, REACH unaffected, and share ECCN EAR99 and HTSUS 8541.10.0080.

Q5: Are mounting and moisture sensitivity specifications consistent?
A5: All alternatives offer through-hole mounting and MSL 1 (unlimited) rating.
