R4000-AP Equivalent & Substitute Parts

Part Overview

The R4000-AP is a general-purpose rectifier diode rated for 4000 V DC reverse voltage with 200 mA average rectified current in a DO-15 axial through-hole package. Manufactured by Micro Commercial Co, this component is classified as obsolete. Due to its obsolete status and limited current inventory availability, identifying equivalent substitute parts is necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the R4000-AP is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Requirements:

• Voltage - DC Reverse (Vr) rating must equal or exceed 4000 V
• Current - Average Rectified (Io) rating must equal or exceed 200 mA
• Current - Reverse Leakage @ Vr must not exceed 5 µA @ 4000 V
• Mounting type must be Through Hole
• Package must be axial configuration compatible with DO-15 or equivalent DO-204 series

Compliance Requirements:

• RoHS3 Compliant status required
• Moisture Sensitivity Level (MSL) of 1 (Unlimited)

The GI250-4-E3/54 meets all substitution criteria with equivalent or superior electrical ratings and maintains full compliance with environmental standards.

Engineering Selection Recommendations

The GI250-4-E3/54 is a direct functional substitute for the obsolete R4000-AP. Selection of this substitute is supported by the following factors:

Product Status: The GI250-4-E3/54 maintains Active product status with substantial inventory availability (75,400 pcs), ensuring long-term procurement reliability compared to the obsolete R4000-AP (1,022 pcs).

Electrical Performance: The substitute meets all minimum electrical requirements with equivalent reverse voltage rating (4000 V) and reverse leakage current (5 µA @ 4000 V). The higher current rating (250 mA vs. 200 mA) and lower forward voltage drop (3.5 V vs. 5 V @ rated current) provide operational margin.

Compliance: Both components maintain ROHS3 compliance, EAR99 export classification, and identical HTSUS coding. Moisture sensitivity levels are equivalent at MSL 1 (Unlimited).

Thermal Performance: The substitute supports an extended operating temperature range (-65°C ~ 175°C vs. -65°C ~ 150°C), providing additional thermal margin for circuit applications.

Package Compatibility: Both components utilize axial through-hole mounting in compatible DO-204 series packages (DO-15 and DO-204AL/DO-41 are mechanically and electrically interchangeable in standard PCB layouts).

Frequently Asked Questions (FAQ)

Q: Can the GI250-4-E3/54 directly replace the R4000-AP in existing designs?

A: Yes. The GI250-4-E3/54 meets all electrical and mechanical requirements for direct substitution. Both components share identical reverse voltage ratings (4000 V), equivalent reverse leakage characteristics (5 µA @ 4000 V), and compatible axial through-hole packages. The substitute's higher current rating and lower forward voltage provide operational margin.

Q: What are the key differences between these parts?

A: The primary differences are product status (Active vs. Obsolete), current rating (250 mA vs. 200 mA), forward voltage drop (3.5 V vs. 5 V @ rated current), and operating temperature range (-65°C ~ 175°C vs. -65°C ~ 150°C). All differences favor the substitute part.

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

A: Yes. Both packages are axial through-hole configurations within the DO-204 family. DO-15 and DO-204AL (DO-41) are mechanically and electrically interchangeable for standard PCB applications with standard 0.3-inch lead spacing.

Q: Does the GI250-4-E3/54 meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, identical ECCN classification (EAR99), and matching HTSUS codes (8541.10.0070).

Q: What is the impact of the lower forward voltage drop in the substitute?

A: The GI250-4-E3/54 exhibits lower forward voltage drop (3.5 V @ 250 mA vs. 5 V @ 200 mA). This results in reduced power dissipation and heat generation in the circuit, improving overall efficiency and thermal performance.

Q: Is inventory availability a consideration for this substitution?

A: Yes. The GI250-4-E3/54 has significantly higher inventory availability (75,400 pcs vs. 1,022 pcs) and Active product status, ensuring reliable long-term procurement compared to the obsolete R4000-AP.
