Key Parameters

Substitute Part Grouping Explanation

Substitution of the DLN10C-BT is determined by electrical and mechanical parameter alignment within the rectifier diode category. The primary substitution criteria are:

Electrical Parameters (Critical):

• Voltage - DC Reverse (Vr) (Max): 200 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 35 ns or lower

Mechanical Parameters (Critical):

• Mounting Type: Through Hole
• Package / Case: Axial configuration

Compliance Parameters:

• REACH Status: REACH Unaffected
• ECCN: EAR99

The MUR120RLG meets all critical electrical and mechanical substitution criteria. It maintains identical voltage and current ratings, equivalent fast recovery speed classification, and identical reverse recovery time. Both components feature through-hole axial mounting and share identical REACH and ECCN compliance status. The MUR120RLG is classified as active product status, making it suitable for direct substitution in applications currently using the obsolete DLN10C-BT.

Engineering Selection Recommendations

The MUR120RLG is the direct active equivalent for the obsolete DLN10C-BT. Selection of the MUR120RLG is based on the following engineering factors:

Product Status: The MUR120RLG carries active product status, ensuring continued availability and manufacturing support, whereas the DLN10C-BT is obsolete and subject to discontinuation.

Electrical Equivalence: Both components share identical voltage ratings (200 V), current ratings (1 A), and reverse recovery time (35 ns). The MUR120RLG demonstrates improved performance characteristics with lower forward voltage drop (875 mV versus 980 mV) and reduced reverse leakage current (2 µA versus 10 µA).

Compliance Alignment: Both parts maintain identical REACH and ECCN compliance status, ensuring regulatory consistency in procurement and deployment.

Temperature Performance: The MUR120RLG provides an extended operating temperature range (-65°C to 175°C) compared to the DLN10C-BT (maximum 150°C), offering improved thermal margin in applications subject to temperature variation.

Package Compatibility: Both components utilize axial through-hole mounting. The MUR120RLG is supplied in DO-204AL and DO-41 packages, which are standard axial configurations compatible with existing PCB layouts designed for the DLN10C-BT R-1 axial package.

Frequently Asked Questions (FAQ)

Q: Can the MUR120RLG be used as a direct replacement for the DLN10C-BT in existing designs?

A: Yes. The MUR120RLG meets all critical electrical parameters (200 V reverse voltage, 1 A current rating, 35 ns reverse recovery time) and mechanical requirements (through-hole axial mounting). Both components are classified as fast recovery diodes with identical speed characteristics. The MUR120RLG is suitable for direct substitution in applications currently using the DLN10C-BT.

Q: What are the key differences between the DLN10C-BT and MUR120RLG?

A: The primary differences are product status and performance characteristics. The DLN10C-BT is obsolete, while the MUR120RLG is active. The MUR120RLG exhibits lower forward voltage drop (875 mV versus 980 mV at 1 A) and lower reverse leakage current (2 µA versus 10 µA at 200 V). The MUR120RLG also provides an extended operating temperature range (-65°C to 175°C versus 150°C maximum).

Q: Are there package compatibility considerations when substituting the MUR120RLG for the DLN10C-BT?

A: Both components use axial through-hole mounting. The DLN10C-BT is packaged in R-1 axial configuration, while the MUR120RLG is supplied in DO-204AL and DO-41 axial packages. These are standard axial package variants with compatible lead spacing and mounting characteristics suitable for existing through-hole PCB designs.

Q: What is the significance of the improved forward voltage and leakage current in the MUR120RLG?

A: Lower forward voltage drop reduces power dissipation during conduction, improving circuit efficiency. Reduced reverse leakage current minimizes standoff current and improves circuit performance during reverse bias conditions. These improvements represent enhanced performance characteristics of the active MUR120RLG compared to the obsolete DLN10C-BT.

Q: Do the DLN10C-BT and MUR120RLG share identical compliance certifications?

A: Yes. Both components maintain identical REACH and ECCN compliance status (REACH Unaffected, EAR99), ensuring regulatory consistency for procurement and deployment in controlled environments.

Q: Why is the MUR120RLG classified as the substitute for the DLN10C-BT?

A: The MUR120RLG is classified as the substitute based on electrical parameter equivalence (identical voltage, current, and speed ratings), mechanical compatibility (through-hole axial mounting), and active product status. The DLN10C-BT is obsolete, making the active MUR120RLG the appropriate long-term alternative for ongoing design and procurement requirements.
