MUR110-TP Equivalent & Substitute Parts

Part Overview

The MUR110-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 100 V DC reverse voltage and 1 A average rectified current in a through-hole DO-41 package. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and procurement needs. Substitute parts must maintain electrical and mechanical compatibility while meeting current product availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MUR110-TP is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: DO-204AL, DO-41, Axial (through-hole axial configuration)

Compliance & Availability Criteria:

• RoHS3 Compliance required
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• Product Status: Active preferred (obsolete parts unsuitable for new procurement)

The UF4002-E3/54 meets all electrical and mechanical substitution criteria while offering active product status and current availability.

Engineering Selection Recommendations

Primary Substitute: UF4002-E3/54

The UF4002-E3/54 is the qualified substitute for the MUR110-TP based on the following factors:

1. Electrical Equivalence: Maintains identical voltage rating (100 V), current rating (1 A), and speed classification (Fast Recovery ≤ 500ns, > 200mA).

2. Mechanical Compatibility: Identical through-hole axial package configuration (DO-204AL, DO-41) ensures direct board-level substitution without layout modification.

3. Compliance Status: Both components are ROHS3 compliant with MSL 1 (Unlimited), meeting regulatory and environmental requirements.

4. Product Availability: UF4002-E3/54 holds active product status with 1300 pieces in current inventory, addressing the obsolescence of the MUR110-TP.

5. Parameter Tolerance: All electrical parameters of the UF4002-E3/54 fall within acceptable operational ranges relative to the MUR110-TP. Forward voltage (1 V vs. 975 mV), reverse recovery time (50 ns vs. 45 ns), and reverse leakage current (10 µA vs. 5 µA) represent minor variations that do not compromise circuit functionality in standard rectification applications.

6. Temperature Range: The UF4002-E3/54 extends the lower operating temperature limit to -55°C, providing enhanced performance margin in cold-environment applications.

Frequently Asked Questions (FAQ)

Q: Can the UF4002-E3/54 be used as a direct replacement for the MUR110-TP in existing designs?

A: Yes. The UF4002-E3/54 is electrically and mechanically equivalent to the MUR110-TP. Both components share identical voltage ratings (100 V), current ratings (1 A), package configuration (DO-41 through-hole axial), and speed classification (Fast Recovery). Direct substitution on the PCB is possible without circuit redesign.

Q: What are the differences in forward voltage between these parts?

A: The MUR110-TP specifies a maximum forward voltage of 975 mV at 1 A, while the UF4002-E3/54 specifies 1 V at 1 A. This 25 mV difference is negligible in rectification circuits and does not affect circuit performance or component selection.

Q: How do the reverse recovery times compare?

A: The MUR110-TP has a reverse recovery time of 45 ns, while the UF4002-E3/54 is specified at 50 ns. Both fall within the Fast Recovery classification (≤ 500ns, > 200mA). The 5 ns difference is insignificant for standard rectification applications and does not impact switching performance.

Q: Are there any temperature range considerations?

A: The MUR110-TP operates from -50°C to 150°C, while the UF4002-E3/54 extends to -55°C to 150°C. The UF4002-E3/54 provides a 5°C lower temperature margin, which is advantageous in cold-environment applications. Both components maintain identical upper temperature limits.

Q: What is the significance of the reverse leakage current difference?

A: The MUR110-TP specifies 5 µA reverse leakage at 100 V, while the UF4002-E3/54 specifies 10 µA. This difference is within acceptable limits for general-purpose rectification. In low-leakage applications requiring minimal reverse current, the MUR110-TP specification is superior, but the UF4002-E3/54 remains suitable for standard rectifier circuits.

Q: Are both parts RoHS compliant?

A: Yes. Both the MUR110-TP and UF4002-E3/54 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting current environmental and regulatory standards.

Q: Why is the MUR110-TP classified as obsolete?

A: The MUR110-TP is no longer in active production. The UF4002-E3/54 is the active equivalent from Vishay, offering current availability and ongoing manufacturer support.

Q: Can the UF4002-E3/54 be used in high-frequency switching applications?

A: Both components are classified as Fast Recovery diodes with reverse recovery times suitable for switching applications up to the specified frequency limits. The 50 ns recovery time of the UF4002-E3/54 is appropriate for standard switching rectifier circuits. Application-specific frequency requirements should be verified against the complete datasheet specifications.
