Substitute Part Grouping Explanation

Substitution of the R1800F-AP with RGP02-18E-E3/54 is based on matching the following critical electrical and mechanical parameters:

Matched Parameters:

• Voltage - DC Reverse (Vr) (Max): 1800 V
• Current - Average Rectified (Io): 500 mA
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA
• Mounting Type: Through Hole
• Package / Case: DO-204AL, DO-41, Axial
• Technology: Standard
• RoHS Status: ROHS3 Compliant

The RGP02-18E-E3/54 maintains electrical equivalence across all primary voltage and current ratings while offering improved performance in forward voltage drop and reverse recovery time. Both components are classified as fast recovery diodes with identical reverse voltage and current specifications, confirming functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The RGP02-18E-E3/54 is the direct substitute for the obsolete R1800F-AP based on product status and compliance certifications. The substitute part is currently active in production, ensuring long-term availability and supply chain continuity. Both components maintain ROHS3 compliance and identical moisture sensitivity classification, confirming regulatory equivalence.

The RGP02-18E-E3/54 demonstrates superior performance characteristics, including reduced forward voltage drop (1.8 V at 100 mA versus 2.4 V at 500 mA) and faster reverse recovery time (300 ns versus 500 ns). The extended operating temperature range (-65°C to 175°C versus -55°C to 150°C) provides additional thermal margin for demanding applications. These improvements do not compromise compatibility; they enhance circuit performance while maintaining electrical equivalence at the specified voltage and current ratings.

Frequently Asked Questions (FAQ)

Q: Can RGP02-18E-E3/54 directly replace R1800F-AP in existing designs?

A: Yes. Both components share identical voltage ratings (1800 V), current ratings (500 mA), speed classification (fast recovery ≤ 500ns), and through-hole DO-41 packaging. Electrical and mechanical compatibility is confirmed across all primary specifications.

Q: What are the key differences between these parts?

A: The RGP02-18E-E3/54 offers improved forward voltage characteristics (1.8 V at 100 mA) and faster reverse recovery time (300 ns), compared to the R1800F-AP (2.4 V at 500 mA and 500 ns). The substitute also provides an extended operating temperature range (-65°C to 175°C versus -55°C to 150°C) and active product status.

Q: Are there packaging considerations for substitution?

A: Both parts use identical through-hole axial packaging (DO-204AL, DO-41). Physical dimensions and lead configurations are compatible, allowing direct board-level substitution without layout modifications.

Q: Why is the R1800F-AP classified as obsolete?

A: The R1800F-AP is no longer in active production. The RGP02-18E-E3/54 provides equivalent functionality with enhanced performance and ongoing manufacturer support.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, confirming regulatory equivalence for procurement and assembly processes.

Q: What is the basis for electrical equivalence?

A: Equivalence is established through matching reverse voltage (1800 V), average rectified current (500 mA), reverse leakage current (5 µA at 1800 V), and fast recovery speed classification (≤ 500ns, > 200mA). These parameters define functional interchangeability in rectification applications.
