Engineering Selection Recommendations

1N5402G (Taiwan Semiconductor Corporation)

The 1N5402G is an active product offering full electrical equivalence to the 1N5402GP-TP. It matches all mandatory parameters: 200 V reverse voltage, 3 A average rectified current, DO-201AD package, and through-hole mounting. Forward voltage is 1.0 V @ 3 A, which is within acceptable variation. Capacitance is 25 pF, lower than the main part but within acceptable range. This part is ROHS3 compliant and carries Active product status, making it suitable for new designs and ongoing production support.

BY251P-E3/54 (Vishay General Semiconductor - Diodes Division)

The BY251P-E3/54 is a parametric equivalent with Active product status. It provides identical electrical performance to the 1N5402GP-TP: 200 V reverse voltage, 3 A average rectified current, 1.1 V forward voltage @ 3 A, and 40 pF capacitance. The DO-201AD package and through-hole mounting are identical. This part includes specified reverse recovery time of 3 µs. ROHS3 compliance and REACH unaffected status are confirmed. Packaging is Cut Tape (CT) rather than Tape & Reel (TR).

1N5402RLG (onsemi)

The 1N5402RLG meets all mandatory electrical parameters: 200 V reverse voltage, 3 A average rectified current, and through-hole axial mounting. Forward voltage is 1.0 V @ 3 A. Reverse leakage is 10 µA @ 200 V, which is within acceptable variation. Operating temperature range extends to -65°C minimum, providing broader low-temperature capability. Product status is "Not For New Designs." Packaging is Cut Tape (CT). This part is suitable for legacy system replacement where the extended temperature range is not a requirement.

Frequently Asked Questions (FAQ)

Q: Can the 1N5402G directly replace the 1N5402GP-TP in existing circuits?

A: Yes. The 1N5402G provides full electrical and mechanical equivalence. Both parts share identical voltage ratings (200 V), current ratings (3 A), package type (DO-201AD), and mounting configuration (through-hole axial). The 1N5402G is an Active product, making it the preferred choice for ongoing production.

Q: What is the difference between the 1N5402GP-TP and BY251P-E3/54?

A: Both parts are electrically equivalent with identical voltage and current ratings. The primary difference is manufacturer: Micro Commercial Co versus Vishay. The BY251P-E3/54 is supplied in Cut Tape (CT) packaging rather than Tape & Reel (TR). Both are ROHS3 compliant and suitable for direct substitution.

Q: Why does the 1N5402RLG show a different operating temperature minimum (-65°C vs. -55°C)?

A: The 1N5402RLG, manufactured by onsemi, has a wider operating temperature range (-65°C to 150°C) compared to the 1N5402GP-TP (-55°C to 150°C). This extended range does not prevent substitution; it indicates the part can operate reliably at lower temperatures. For applications operating within -55°C to 150°C, both parts are equivalent.

Q: What does "Not For New Designs" mean for the 1N5402GP-TP and 1N5402RLG?

A: "Not For New Designs" indicates the manufacturer has discontinued active development and recommends using alternative parts for new circuit designs. However, these parts remain available for legacy system support and maintenance. For new designs, 1N5402G or BY251P-E3/54 (both Active status) are recommended.

Q: Are there packaging differences between these substitute parts?

A: Yes. The 1N5402GP-TP and 1N5402G are supplied in Tape & Reel (TR) packaging. The 1N5402RLG and BY251P-E3/54 are supplied in Cut Tape (CT) packaging. Both packaging formats are compatible with through-hole assembly processes; the choice depends on production equipment and volume requirements.

Q: What is the significance of reverse leakage current variation (5 µA vs. 10 µA)?

A: Reverse leakage current is the small current flowing through the diode when reverse-biased. The 1N5402RLG specifies 10 µA @ 200 V, while the main part and other substitutes specify 5 µA @ 200 V. Both values are within acceptable limits for general-purpose rectification. The higher leakage in the 1N5402RLG does not prevent substitution in standard applications.

Q: Can I use these parts interchangeably in high-frequency switching applications?

A: All listed parts are classified as Standard Recovery diodes with recovery time >500 ns. They are designed for general-purpose rectification and power supply applications, not high-frequency switching. For switching applications requiring fast recovery times, specialized fast-recovery or Schottky diodes are required.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts (1N5402G, 1N5402RLG, BY251P-E3/54) are ROHS3 compliant and REACH unaffected. ECCN classification is EAR99 for all parts. These certifications ensure compliance with environmental and export regulations.
