Engineering Selection Recommendations

Vishay SUPERECTIFIER® Series Equivalents (RGL41J-E3/96, RGL41J-E3/97, BYM11-600-E3/96, BYM11-600-E3/97):

These four part numbers provide complete electrical and mechanical equivalence to the RGL41J/1. All maintain identical specifications for voltage rating, current capacity, forward voltage drop, reverse recovery time, and reverse leakage current. The primary differences are packaging format and RoHS compliance status. RGL41J-E3/96 and RGL41J-E3/97 retain the RGL41 base product number with ROHS3 compliance, while BYM11-600-E3/96 and BYM11-600-E3/97 use the BYM11 base product number, also with ROHS3 compliance. All four are available in Tape & Reel or Cut Tape formats. Selection among these four should be based on packaging requirements and supply chain availability.

Microchip 1N6663US (Cross-Manufacturer Alternative):

The 1N6663US from Microchip Technology operates at the same 600 V reverse voltage and maintains fast recovery characteristics. However, this part is rated for 500 mA average rectified current, which is 50% of the RGL41J/1 rating. The 1N6663US exhibits superior reverse leakage characteristics (50 nA versus 5 µA) and lower forward voltage drop (1 V @ 400 mA). The package designation differs (SQ-MELF, A versus DO-213AB, MELF). This part is suitable only for applications where the 500 mA current rating is sufficient and where the different package footprint is acceptable. The 1N6663US is RoHS non-compliant, matching the compliance status of the original RGL41J/1.

Compliance Considerations:

If RoHS3 compliance is required, select from RGL41J-E3/96, RGL41J-E3/97, BYM11-600-E3/96, or BYM11-600-E3/97. If RoHS compliance is not a requirement, the original RGL41J/1 or the 1N6663US remain valid selections based on current rating and package compatibility.

Frequently Asked Questions (FAQ)

Q: Can RGL41J-E3/96 and RGL41J-E3/97 be used interchangeably with RGL41J/1?

A: Yes. Both parts are electrically and mechanically identical to RGL41J/1. The primary difference is packaging format: RGL41J-E3/96 is supplied in Cut Tape format, while RGL41J-E3/97 is supplied in Tape & Reel format. Both achieve ROHS3 compliance, whereas the original RGL41J/1 is RoHS non-compliant.

Q: What is the difference between BYM11-600-E3/96 and BYM11-600-E3/97?

A: These parts are electrically identical and differ only in packaging delivery method. BYM11-600-E3/96 is supplied in Cut Tape & Digi-Reel® format, while BYM11-600-E3/97 is supplied in Tape & Reel format. Both maintain identical electrical specifications and ROHS3 compliance.

Q: Is the 1N6663US a direct replacement for RGL41J/1?

A: The 1N6663US is not a direct replacement. While it maintains the same 600 V reverse voltage rating and fast recovery speed classification, it is rated for 500 mA average rectified current compared to the RGL41J/1's 1 A rating. The 1N6663US is suitable only for applications where the lower current rating is acceptable. Additionally, the package designation differs (SQ-MELF, A versus DO-213AB, MELF), which may affect PCB footprint compatibility.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: Voltage - DC Reverse (Vr) of 600 V, Current - Average Rectified (Io) of 1 A, fast recovery speed classification (≤ 500ns, > 200mA), reverse recovery time of 250 ns, and operating temperature range of -65°C to 175°C. Package type must be DO-213AB, MELF (Glass) surface mount.

Q: Can I use RGL41J-E3/96 in place of RGL41J/1 if my design requires RoHS compliance?

A: Yes. RGL41J-E3/96 is ROHS3 compliant and maintains complete electrical and mechanical equivalence to RGL41J/1. The Cut Tape packaging format is suitable for automated assembly processes.

Q: What is the significance of the reverse leakage current difference between RGL41J/1 and 1N6663US?

A: The 1N6663US exhibits 50 nA reverse leakage at 600 V, compared to 5 µA for RGL41J/1. This represents superior leakage performance in the Microchip device. However, this advantage is offset by the lower current rating (500 mA versus 1 A) and different package type, making the 1N6663US suitable only for specific applications where these characteristics align with design requirements.

Q: Are all substitute parts rated for the same operating temperature range?

A: Yes. All listed substitute parts, including RGL41J-E3/96, RGL41J-E3/97, BYM11-600-E3/96, BYM11-600-E3/97, and 1N6663US, are rated for junction operating temperatures from -65°C to 175°C, matching the RGL41J/1 specification.

Q: What packaging formats are available for the Vishay SUPERECTIFIER® equivalents?

A: The Vishay equivalents are available in three packaging formats: Cut Tape (CT) & Digi-Reel® (BYM11-600-E3/96), Tape & Reel (TR) (RGL41J-E3/97, RGL41J-E3/97, BYM11-600-E3/97), and Bulk (original RGL41J/1). Selection depends on assembly process requirements and supply chain preferences.
