DLE30C-KC9 Equivalent & Substitute Parts

Part Overview

The DLE30C-KC9 is a general-purpose rectifier diode manufactured by onsemi, rated for 200 V DC reverse voltage and 3 A average rectified current in a through-hole axial package (DO-201AD). This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design requirements and procurement needs. The DLE30C-KC9 features fast recovery characteristics with a reverse recovery time of 35 ns, making it suitable for standard rectification applications requiring moderate switching speeds.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete DLE30C-KC9 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 3 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Through Hole
• Package / Case: DO-201AD, Axial

Acceptable Parameter Variations:

• Voltage - Forward (Vf) (Max) @ If: Minor variations within standard rectifier tolerances
• Reverse Recovery Time (trr): Variations within fast recovery classification
• Current - Reverse Leakage @ Vr: Variations at different measurement voltages within acceptable limits
• Operating Temperature Range: Extended ranges are acceptable for substitution

The UF5402-E3/54 manufactured by Vishay General Semiconductor - Diodes Division meets all substitution criteria and is classified as an active product with current availability.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The DLE30C-KC9 is classified as obsolete, while the UF5402-E3/54 is an active product with confirmed current inventory (2900 pcs). For new designs and ongoing procurement, the UF5402-E3/54 is the appropriate selection.

Compliance and Certification: Both parts share identical REACH status (REACH Unaffected) and ECCN classification (EAR99). The UF5402-E3/54 carries RoHS3 compliance certification, providing additional regulatory alignment for modern manufacturing environments.

Electrical Performance: The UF5402-E3/54 maintains all critical electrical specifications within acceptable engineering tolerances. The forward voltage differential (20 mV higher at 3 A) and reverse recovery time increase (15 ns) remain within standard rectifier performance bands and do not compromise circuit functionality for general-purpose rectification applications.

Mechanical and Thermal Compatibility: Identical package designation (DO-201AD, Axial) and mounting type (Through Hole) ensure direct mechanical substitution without PCB redesign. The extended operating temperature range of the UF5402-E3/54 (-55°C to 150°C versus 150°C maximum for the DLE30C-KC9) provides superior thermal margin.

Frequently Asked Questions (FAQ)

Q: Can the UF5402-E3/54 be used as a direct replacement for the DLE30C-KC9 in existing designs?

A: Yes. The UF5402-E3/54 meets all electrical and mechanical substitution criteria. Identical voltage ratings (200 V), current ratings (3 A), package type (DO-201AD, Axial), and mounting configuration (Through Hole) enable direct substitution without circuit modification or PCB redesign.

Q: What are the key differences between these two parts?

A: The primary differences are product status (DLE30C-KC9 is obsolete; UF5402-E3/54 is active), forward voltage (980 mV versus 1 V at 3 A), reverse recovery time (35 ns versus 50 ns), and operating temperature range (-55°C to 150°C for UF5402-E3/54 versus 150°C maximum for DLE30C-KC9). These differences do not affect substitution suitability for standard rectification applications.

Q: Are there any packaging differences between the DLE30C-KC9 and UF5402-E3/54?

A: Both parts use the DO-201AD axial package with through-hole mounting. The UF5402-E3/54 is supplied in Cut Tape (CT) packaging format, which is standard for active production components. No physical or dimensional differences affect PCB compatibility.

Q: What compliance certifications apply to the UF5402-E3/54?

A: The UF5402-E3/54 is RoHS3 compliant and carries REACH Unaffected status. Both parts share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: Is the UF5402-E3/54 suitable for high-temperature applications?

A: The UF5402-E3/54 supports an operating temperature range of -55°C to 150°C, providing extended thermal capability compared to the DLE30C-KC9 (150°C maximum). This makes it suitable for applications requiring broader temperature margins.

Q: How does the reverse recovery time difference affect circuit performance?

A: The UF5402-E3/54 has a reverse recovery time of 50 ns compared to 35 ns for the DLE30C-KC9. Both remain within the fast recovery classification (≤ 500ns, > 200mA). For general-purpose rectification, this 15 ns difference does not impact circuit functionality or switching performance.
