R3000F-AP Equivalent & Substitute Parts

Part Overview

The R3000F-AP 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 package and mounting variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the R3000F-AP 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 equivalent blocking capability in high-voltage applications.

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

Package and Mounting: Both through-hole axial packages (DO-15 and DO-204AL/DO-41) are mechanically compatible in standard PCB layouts designed for axial lead components.

Reverse Recovery Characteristics: The substitute part may exhibit different reverse recovery time specifications. Standard recovery diodes with trr > 500 ns are acceptable for general-purpose rectification applications where switching speed is not a critical constraint.

Thermal Range: The substitute part must support the operating junction temperature range or provide an extended range that encompasses the original specification.

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

Engineering Selection Recommendations

The GI250-3-E3/54 is a direct functional substitute for the obsolete R3000F-AP based on the following criteria:

Electrical Equivalence: 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, providing operational margin without introducing circuit incompatibility.

Compliance and Certification: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent manufacturing and environmental compatibility.

Product Availability: The R3000F-AP is obsolete with no ongoing production. The GI250-3-E3/54 is in active production status with substantial inventory availability (17,110 pieces), ensuring long-term supply chain continuity.

Thermal Performance: The substitute's extended operating temperature range (-65°C to 175°C) encompasses and exceeds the original specification (-55°C to 150°C), providing enhanced thermal margin for demanding applications.

Package Compatibility: Both components utilize through-hole axial packages (DO-15 and DO-204AL/DO-41) that are mechanically interchangeable in standard PCB designs without layout modification.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical 3000 V reverse voltage and reverse leakage specifications. The substitute's higher 250 mA current rating is compatible with circuits designed for 200 mA operation. Through-hole axial packages are mechanically interchangeable in standard PCB layouts.

Q: What is the significance of the different reverse recovery times (500 ns vs. 2 µs)?

A: The R3000F-AP is a small-signal diode with fast recovery (500 ns), while the GI250-3-E3/54 is a standard recovery diode (2 µs). For general-purpose rectification applications, standard recovery characteristics are acceptable. Fast recovery is required only in high-frequency switching circuits; general-purpose rectification does not impose this constraint.

Q: Are there package considerations when substituting these parts?

A: Both parts are through-hole axial components. The R3000F-AP uses DO-204AC/DO-15 packaging, while the substitute uses DO-204AL/DO-41 packaging. These packages have identical lead spacing and mechanical footprints, requiring no PCB layout changes.

Q: Does the lower forward voltage drop of the substitute affect circuit operation?

A: The substitute exhibits 3.5 V forward voltage at 250 mA compared to 5 V at 500 mA for the original part. Lower forward voltage drop reduces power dissipation and heat generation, which is beneficial for circuit efficiency. This does not introduce incompatibility.

Q: What is the impact of the substitute's lower junction capacitance?

A: The substitute's 3 pF capacitance (versus 30 pF for the original) reduces parasitic capacitive effects. This is advantageous in high-frequency applications and does not introduce circuit incompatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the R3000F-AP and GI250-3-E3/54 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and manufacturing compliance.

Q: Why is the R3000F-AP classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The GI250-3-E3/54 provides an active, readily available alternative with equivalent electrical specifications and superior availability for new designs and production continuity.
