MUR440HB0G Equivalent & Substitute Parts

Part Overview

The MUR440HB0G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 V DC reverse voltage and 4 A average rectified current in a DO-201AD through-hole axial package. This component is classified as Active product status and carries AEC-Q101 automotive qualification. The MUR440HB0G is ROHS3 compliant with unlimited moisture sensitivity (MSL 1).

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit operation within the electrical and mechanical parameters of alternative qualified devices. The EGP30G represents a functionally compatible alternative within the same package family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MUR440HB0G is determined by the following critical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 V minimum
• Package / Case: DO-201AD, Axial (mechanical and thermal compatibility)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 50 ns (switching performance)

Allowable Variation Criteria:

• Current - Average Rectified (Io): Equal to or greater than required circuit current
• Voltage - Forward (Vf) (Max): Lower or equal values acceptable
• Current - Reverse Leakage @ Vr: Lower or equal values acceptable
• Operating Temperature - Junction: Range must encompass application requirements

The EGP30G qualifies as a substitute based on matching voltage rating (400 V), identical package (DO-201AD), identical speed classification, and identical reverse recovery time (50 ns). The EGP30G operates at 3 A average rectified current, which is lower than the MUR440HB0G's 4 A rating; therefore, substitution is valid only for applications requiring 3 A or less.

Parameter Comparison

Engineering Selection Recommendations

MUR440HB0G Selection: The MUR440HB0G is the primary choice for new designs. It carries Active product status, indicating full manufacturer support and continued availability. The component holds AEC-Q101 automotive qualification, suitable for automotive and industrial applications requiring long-term reliability. The operating temperature range of -55°C to 175°C accommodates demanding thermal environments. Current rating of 4 A supports higher-power rectification circuits.

EGP30G Selection: The EGP30G carries Not For New Designs product status, indicating the manufacturer has discontinued active development and support for this component. Substitution with EGP30G is restricted to legacy system maintenance, repair, or applications where current requirements do not exceed 3 A. The operating temperature range of -65°C to 150°C is narrower than the MUR440HB0G, with the upper limit 25°C lower. Both components maintain ROHS3 compliance and REACH unaffected status. The EGP30G exhibits lower reverse leakage current (5 µA versus 10 µA), which may provide marginal benefit in low-leakage applications.

Frequently Asked Questions (FAQ)

Q: Can the EGP30G replace the MUR440HB0G in all applications?

A: No. The EGP30G is rated for 3 A average rectified current, while the MUR440HB0G is rated for 4 A. Substitution is valid only for circuits requiring 3 A or less. Additionally, the EGP30G carries Not For New Designs status and has a maximum junction temperature 25°C lower than the MUR440HB0G.

Q: Are the packages physically identical?

A: Yes. Both components use the DO-201AD axial through-hole package. Physical dimensions, lead spacing, and PCB mounting compatibility are identical. No layout modifications are required for package substitution.

Q: What is the significance of the 50 ns reverse recovery time?

A: The reverse recovery time (trr) of 50 ns indicates fast-recovery diode performance, enabling rapid switching transitions. Both the MUR440HB0G and EGP30G share this specification, ensuring equivalent switching behavior in rectification circuits.

Q: Why does the EGP30G have lower reverse leakage current?

A: The EGP30G exhibits 5 µA reverse leakage at 400 V, compared to 10 µA for the MUR440HB0G. This difference reflects manufacturing process variations between manufacturers. Lower leakage may reduce standby power dissipation in certain applications but does not affect primary rectification function.

Q: Is the EGP30G suitable for new product designs?

A: No. The EGP30G carries Not For New Designs product status. New designs must use the MUR440HB0G or equivalent active-status components to ensure long-term supply availability and manufacturer support.

Q: What is the temperature operating range difference?

A: The MUR440HB0G operates from -55°C to 175°C junction temperature, while the EGP30G operates from -65°C to 150°C. The EGP30G has a lower maximum temperature limit, restricting use in high-temperature applications. The MUR440HB0G is preferred for thermal margin in demanding environments.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the MUR440HB0G and EGP30G are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.
