Substitute Part Grouping Explanation

Substitute parts for the FR206G are identified based on the following critical parameters: DC reverse voltage rating (800 V), package type (DO-204AC/DO-15 axial through-hole), and product status (Active). The substitute parts listed maintain the same 800 V voltage rating and identical package configuration, ensuring mechanical and electrical compatibility in circuit applications.

Substitution logic is based on the following allowed parameters:

Voltage - DC Reverse (Vr) (Max): 800 V (required match)
Package / Case: DO-204AC, DO-15, Axial (required match)
Mounting Type: Through Hole (required match)
Product Status: Active (required match)
RoHS Status: ROHS3 Compliant (required match)

Current rating (Io) variations are permitted within the substitute group, as lower-rated devices can operate in circuits designed for higher current capacity. Forward voltage and recovery time characteristics vary among substitutes based on semiconductor technology differences.

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the FR206G. The substitute group comprises three Vishay General Semiconductor - Diodes Division components: 1N5621GP-E3/54, BYV26DGP-E3/73, and GP15K-E3/54.

1N5621GP-E3/54 is suitable for applications where the 2 A current requirement of the FR206G can be reduced to 1 A operation. This substitute offers improved reverse recovery time (300 ns versus 500 ns) and significantly lower reverse leakage current (500 nA versus 5 µA), with extended operating temperature range (-65°C to 175°C).

BYV26DGP-E3/73 is applicable in circuits requiring the fastest reverse recovery performance (75 ns) among the substitute group. This component operates at 1 A current rating and maintains the 800 V voltage specification. Forward voltage is elevated at 2.5 V @ 1 A compared to the FR206G specification.

GP15K-E3/54 provides intermediate current capacity at 1.5 A, positioned between the 1 A substitutes and the original 2 A FR206G rating. This component features the lowest forward voltage drop (1.1 V @ 1.5 A) among substitutes but operates with standard recovery characteristics (3.5 µs reverse recovery time).

Selection among substitutes depends on circuit current requirements, recovery speed specifications, and forward voltage drop constraints. All substitutes share identical 800 V voltage rating, DO-204AC package configuration, and through-hole mounting compatibility with the FR206G.

Frequently Asked Questions (FAQ)

Q: Can the 1N5621GP-E3/54 substitute for the FR206G in all applications?

A: The 1N5621GP-E3/54 is suitable for applications where circuit current requirements do not exceed 1 A. The FR206G is rated for 2 A average rectified current, so substitution is valid only when actual circuit current remains below 1 A maximum rating.

Q: What is the primary difference between BYV26DGP-E3/73 and the other substitutes?

A: The BYV26DGP-E3/73 features the fastest reverse recovery time at 75 ns, compared to 300 ns for 1N5621GP-E3/54 and 3.5 µs for GP15K-E3/54. This characteristic is relevant for high-frequency switching applications. However, forward voltage is higher at 2.5 V @ 1 A.

Q: Are all substitute parts mechanically compatible with the FR206G?

A: Yes. All substitute parts use the DO-204AC (DO-15) axial through-hole package, ensuring identical mechanical compatibility and PCB mounting compatibility with the FR206G.

Q: Does the FR206G have a direct equivalent with identical current rating?

A: Among the listed substitutes, no component matches the 2 A current rating of the FR206G. The GP15K-E3/54 provides the closest current capacity at 1.5 A. For applications requiring full 2 A capacity, the FR206G remains the appropriate selection.

Q: Are temperature operating ranges compatible between FR206G and substitutes?

A: The FR206G operates from -55°C to 150°C junction temperature. All substitute parts extend this range to -65°C to 175°C, providing broader temperature capability. Substitution is valid within the FR206G temperature specification range.

Q: What compliance certifications apply to all parts in this group?

A: All parts including FR206G and substitutes are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement and use.
