R3000F-TP Equivalent & Substitute Parts

Part Overview

The R3000F-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 3000 V DC reverse voltage with 200 mA average rectified current in a DO-15 through-hole axial package. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating available packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the R3000F-TP is based on the following critical electrical and mechanical parameters:

Voltage Compatibility: The substitute part must maintain a DC reverse voltage rating of 3000 V to ensure safe operation in the same circuit topology.

Current Rating: The substitute part current rating must equal or exceed 200 mA average rectified current. Parts with higher current ratings (such as 250 mA) are acceptable as they provide operational margin without compromising circuit function.

Package Type: Both the main part and substitute must be through-hole axial diodes to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Reverse Recovery Characteristics: The substitute part must operate within the small-signal or standard recovery classification appropriate for the application's switching frequency requirements.

Thermal Range: The substitute part operating temperature range must encompass or exceed the -55°C to 150°C specification of the main part.

Compliance: Both parts must maintain ROHS3 compliance and equivalent moisture sensitivity levels to ensure regulatory and environmental compatibility.

The GI250-3-E3/54 meets all substitution criteria through equivalent voltage and leakage specifications, superior current rating, compatible through-hole axial packaging, and active product status.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The R3000F-TP is classified as obsolete, making long-term supply continuity uncertain. The GI250-3-E3/54 maintains active product status with Vishay General Semiconductor, ensuring availability for current and future production requirements.

Electrical Compatibility: Both parts share identical DC reverse voltage (3000 V) and reverse leakage current (5 µA @ 3000 V) specifications. The substitute part's 250 mA current rating exceeds the main part's 200 mA requirement, providing operational margin without circuit redesign.

Thermal Performance: The GI250-3-E3/54 extends the operating temperature range to -65°C to 175°C, compared to the R3000F-TP range of -55°C to 150°C. This wider thermal envelope accommodates more demanding environmental conditions.

Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory compatibility.

Package Compatibility: Both parts utilize through-hole axial configurations (DO-15 and DO-204AL/DO-41 respectively). These packages are mechanically and electrically compatible for PCB mounting and circuit integration.

Recovery Characteristics: The substitute part exhibits standard recovery characteristics (2 µs trr) compared to the main part's small-signal recovery (500 ns trr). This difference is acceptable for applications not requiring high-frequency switching performance.

Frequently Asked Questions (FAQ)

Q: Can the GI250-3-E3/54 directly replace the R3000F-TP in existing designs?

A: Yes. Both parts maintain identical 3000 V reverse voltage and 5 µA reverse leakage specifications. The substitute's 250 mA current rating exceeds the 200 mA requirement, and both utilize compatible through-hole axial packages. No circuit modifications are required.

Q: What is the significance of the different reverse recovery times?

A: The R3000F-TP exhibits 500 ns recovery time (small-signal classification), while the GI250-3-E3/54 exhibits 2 µs recovery time (standard recovery classification). For low-frequency rectification applications, this difference is not functionally significant. High-frequency switching applications should evaluate switching losses based on specific circuit operating frequency.

Q: Are the DO-15 and DO-204AL packages mechanically interchangeable?

A: Both packages are axial through-hole configurations with compatible lead spacing and mounting characteristics. Physical dimensions may vary slightly, but both fit standard through-hole PCB layouts designed for axial diodes. Verify specific PCB footprint requirements for your application.

Q: Why is the substitute part's forward voltage lower?

A: The GI250-3-E3/54 forward voltage specification (3.5 V @ 250 mA) is measured at the part's rated current, while the R3000F-TP specification (5 V @ 500 mA) is measured at a higher current level. Lower forward voltage reduces power dissipation and heat generation in the circuit.

Q: Does the wider operating temperature range of the substitute part affect compatibility?

A: No. The GI250-3-E3/54 temperature range (-65°C to 175°C) encompasses the R3000F-TP range (-55°C to 150°C). The substitute part operates safely across all conditions specified for the original part and extends capability to more extreme temperatures.

Q: Are both parts RoHS compliant?

A: Yes. Both the R3000F-TP and GI250-3-E3/54 maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory compatibility.

Q: What is the inventory status difference between these parts?

A: The R3000F-TP is obsolete with limited remaining inventory (1036 pcs). The GI250-3-E3/54 is an active product with substantial inventory availability (17110 pcs), ensuring reliable supply for production and future requirements.
