Key Parameters

Substitute Part Grouping Explanation

Substitution of the R4000F-TP is determined by the following critical electrical and mechanical parameters:

Voltage Rating: The substitute part must maintain a DC reverse voltage rating of 4000 V to ensure equivalent blocking capability in high-voltage applications.

Current Rating: The substitute part must support the required average rectified current. Parts with equal or higher current ratings are acceptable for direct substitution.

Package Type: The substitute must use a through-hole axial package (DO-15, DO-204AC, or DO-204AL) to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Reverse Recovery Characteristics: The substitute must operate within acceptable reverse recovery parameters for the application. Standard recovery diodes with trr > 500 ns are compatible with small-signal applications.

Temperature Range: The substitute must support the required operating temperature range to ensure reliability across the intended application environment.

Compliance: Both parts must maintain ROHS3 compliance and equivalent moisture sensitivity ratings.

The GI250-4-E3/54 meets all substitution criteria with matching voltage and leakage specifications, higher current capacity, and active product status.

Parameter Comparison

Engineering Selection Recommendations

The GI250-4-E3/54 is a direct substitute for the obsolete R4000F-TP based on the following engineering criteria:

Voltage and Leakage Equivalence: Both parts maintain identical 4000 V DC reverse voltage ratings and 5 µA reverse leakage current at rated voltage, ensuring equivalent blocking performance in high-voltage rectification circuits.

Current Capacity: The GI250-4-E3/54 is rated for 250 mA average rectified current, exceeding the R4000F-TP requirement of 200 mA. This higher rating provides design margin and thermal headroom in the application.

Package Compatibility: Both parts use through-hole axial packages (DO-15 and DO-204AL are mechanically and electrically compatible). PCB layouts designed for the R4000F-TP accommodate the GI250-4-E3/54 without modification.

Active Product Status: The GI250-4-E3/54 is an active product with substantial inventory availability (75,400 pieces), ensuring long-term supply continuity compared to the obsolete R4000F-TP.

Compliance Certification: Both parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity), maintaining equivalent environmental and regulatory compliance.

Temperature Performance: The GI250-4-E3/54 supports an extended operating temperature range (-65°C to 175°C) compared to the R4000F-TP (-65°C to 150°C), providing additional thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the GI250-4-E3/54 directly replace the R4000F-TP in existing designs?

A: Yes. Both parts share identical 4000 V voltage ratings, equivalent reverse leakage characteristics, and compatible through-hole axial packages. The higher current rating of the GI250-4-E3/54 (250 mA vs. 200 mA) presents no compatibility issues and provides additional design margin.

Q: What is the difference between DO-15 and DO-204AL packages?

A: DO-15 and DO-204AL are equivalent designations for the same axial through-hole package. DO-204AL is the formal JEDEC designation, while DO-15 is an alternate industry reference. Both packages have identical mechanical and electrical characteristics and are interchangeable in PCB layouts.

Q: Why does the GI250-4-E3/54 have a lower forward voltage drop than the R4000F-TP?

A: The GI250-4-E3/54 is manufactured using Vishay's SUPERECTIFIER technology, which incorporates advanced semiconductor processing to reduce forward voltage losses. The lower forward voltage (3.5 V @ 250 mA vs. 6.5 V @ 200 mA) results in reduced power dissipation and improved circuit efficiency.

Q: Is the slower reverse recovery time of the GI250-4-E3/54 a concern?

A: No. The GI250-4-E3/54 is classified as a standard recovery diode with 2 µs reverse recovery time, suitable for small-signal and general-purpose rectification applications. The R4000F-TP specification of 500 ns indicates small-signal performance, but both parts operate within acceptable parameters for their respective application categories. The slower recovery of the substitute does not degrade performance in standard rectification circuits.

Q: Are there any thermal considerations when substituting these parts?

A: The GI250-4-E3/54 supports a higher junction temperature range (-65°C to 175°C) compared to the R4000F-TP (-65°C to 150°C). The lower forward voltage of the substitute results in reduced power dissipation, which improves thermal performance. No additional thermal management is required for the substitution.

Q: What is the inventory status of these parts?

A: The R4000F-TP is obsolete with 1,017 pieces available in current stock. The GI250-4-E3/54 is an active product with 75,400 pieces in inventory, ensuring reliable long-term supply availability for production and repair applications.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the R4000F-TP and GI250-4-E3/54 are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity ratings, meeting equivalent environmental and regulatory requirements.
