UF4001-TP Equivalent & Substitute Parts

Part Overview

The UF4001-TP is a general-purpose rectifier diode rated for 50 V DC reverse voltage and 1 A average rectified current in a through-hole DO-41 package. Manufactured by Micro Commercial Co, this component is classified as obsolete. Due to its obsolete status and limited ongoing availability, identifying equivalent and substitute parts from active manufacturers is necessary for design continuity and procurement planning. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating the through-hole axial package format.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UF4001-TP are selected based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Primary Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 50 V
• Current - Average Rectified (Io): Must equal or exceed 1 A
• Mounting Type: Must be Through Hole
• Package / Case: Must be DO-204AL, DO-41, or Axial equivalent
• RoHS Status: Must maintain ROHS3 Compliance

Secondary Compatibility Factors:

• Voltage - Forward (Vf) (Max) @ If: Acceptable range up to 1.1 V @ 1 A
• Current - Reverse Leakage @ Vr: Must not exceed 5 µA @ 50 V
• Operating Temperature - Junction: Extended ranges acceptable for enhanced thermal performance

Substitute parts are grouped into two categories: Upgrade parts (active product status with enhanced specifications) and Similar parts (alternative manufacturers with comparable electrical characteristics).

Engineering Selection Recommendations

UF1A A0G (Taiwan Semiconductor Corporation)

This part is recommended as the primary upgrade substitute. It maintains identical electrical specifications to the UF4001-TP across all critical parameters: 50 V reverse voltage, 1 A average rectified current, 1 V forward voltage drop, and 50 ns reverse recovery time. The part is in active production status with 1039 units in stock. Operating temperature range extends to 150 °C, providing enhanced thermal margin. RoHS3 compliance is maintained. This part is suitable for direct replacement in standard industrial applications.

UF4001HA0G (Taiwan Semiconductor Corporation)

This part is recommended for applications requiring automotive-grade reliability. It matches all electrical specifications of the UF4001-TP and includes AEC-Q101 qualification, indicating compliance with automotive industry standards. Operating temperature range extends to 150 °C. This part is in active production with 849 units in stock. RoHS3 and REACH compliance are confirmed. Selection of this part is appropriate for automotive and mission-critical applications.

1N4001GPE-E3/54 (Vishay General Semiconductor)

This part is available as an alternative from a major semiconductor manufacturer. It meets the core electrical requirements: 50 V reverse voltage and 1 A average rectified current. Forward voltage is 1.1 V at 1 A, which is within acceptable tolerance for general-purpose rectification. Reverse recovery time is 2 µs, indicating standard recovery speed rather than fast recovery. Operating temperature range extends to 175 °C. This part is in active production with 11704 units in stock. RoHS3 and REACH compliance are confirmed. This part is suitable for applications where fast recovery is not a critical requirement.

Frequently Asked Questions (FAQ)

Q: Can the UF1A A0G directly replace the UF4001-TP without circuit modification?

A: Yes. The UF1A A0G maintains identical electrical specifications across voltage rating, current rating, forward voltage drop, and reverse recovery time. Both parts use the same through-hole DO-41 package. No circuit modification is required.

Q: What is the difference between the UF1A A0G and UF4001HA0G?

A: Both parts have identical electrical specifications. The UF4001HA0G includes automotive-grade qualification (AEC-Q101) and is designated for automotive applications. The UF1A A0G is a standard industrial-grade part. Selection depends on application requirements.

Q: Why does the 1N4001GPE-E3/54 have a longer reverse recovery time (2 µs vs. 50 ns)?

A: The 1N4001GPE-E3/54 uses standard recovery technology, while the UF4001-TP and upgrade parts use fast recovery technology. This difference affects switching speed in high-frequency applications. For low-frequency rectification, this difference is not significant.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance, matching the environmental compliance status of the UF4001-TP.

Q: Can I use the 1N4001GPE-E3/54 in a circuit designed for the UF4001-TP?

A: Yes, with consideration of application requirements. The 1N4001GPE-E3/54 meets voltage and current specifications. However, the higher forward voltage (1.1 V vs. 1 V) and longer reverse recovery time (2 µs vs. 50 ns) may affect performance in high-frequency switching or precision rectification circuits. For standard low-frequency rectification, compatibility is confirmed.

Q: What is the inventory status of substitute parts?

A: UF1A A0G: 1039 units in stock. UF4001HA0G: 849 units in stock. 1N4001GPE-E3/54: 11704 units in stock. All parts are available as new original components.

Q: Do the substitute parts support the same operating temperature range as the UF4001-TP?

A: The UF4001-TP operates from -55 °C to 125 °C. Both upgrade parts (UF1A A0G and UF4001HA0G) extend the upper limit to 150 °C. The 1N4001GPE-E3/54 extends the range to -65 to 175 °C. All substitute parts support the original temperature range and provide extended capability.
