Substitute Part Grouping Explanation

Substitute parts for the GL41GHE3/97 are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Vishay SUPERECTIFIER® Series): Parts 1N6481-E3/96, BYM10-400-E3/96, GL41G-E3/96, GL41G-E3/97, and GL41GHE3/96 share identical electrical specifications with the main part: 400 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A, standard recovery speed, 10 µA reverse leakage at 400 V, and 8 pF capacitance. All are housed in DO-213AB MELF glass packages with surface mount configuration. These parts differ only in packaging format (Tape & Reel, Cut Tape & Digi-Reel®) and manufacturing date codes, allowing direct functional substitution within the same design.

Manufacturer Recommended Alternative (Microchip Technology): Part 1N5616US represents a cross-manufacturer option with matching 400 V reverse voltage and 1 A average rectified current ratings. However, this part uses a different package format (SQ-MELF, A / D-5A) and exhibits different electrical characteristics including 1.3 V forward voltage at 3 A, 2 µs reverse recovery time, and 500 nA reverse leakage at 400 V. This part is RoHS non-compliant and operates to 200°C junction temperature. Selection of this alternative requires design verification for package compatibility and thermal performance.

Engineering Selection Recommendations

Primary Substitutes (Vishay SUPERECTIFIER® Series): Parts 1N6481-E3/96, BYM10-400-E3/96, GL41G-E3/96, GL41G-E3/97, and GL41GHE3/96 are direct functional equivalents to GL41GHE3/97. All five parts maintain ROHS3 compliance and MSL 1 rating. Selection among these parts is determined by packaging availability and supply chain requirements. GL41G-E3/97 and GL41GHE3/96 offer the highest inventory levels (13,811 and 5,100 units respectively) among Vishay equivalents. BYM10-400-E3/96 differs only in technology classification (Avalanche versus Standard) while maintaining identical electrical specifications and package format.

Alternative Manufacturer Option: The 1N5616US from Microchip Technology is electrically compatible for 400 V / 1 A applications but introduces design considerations. This part is RoHS non-compliant, which may conflict with regulatory requirements in applications subject to ROHS3 mandates. The different package format (SQ-MELF, A versus DO-213AB MELF) requires PCB layout verification. The 500 nA reverse leakage (versus 10 µA) and extended temperature range to 200°C may provide performance advantages in specific thermal environments, but forward voltage characteristics differ at the specified test current.

Frequently Asked Questions (FAQ)

Q: Can GL41GHE3/97 be directly replaced with 1N6481-E3/96?

A: Yes. Both parts share identical electrical specifications (400 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A, 10 µA reverse leakage, 8 pF capacitance) and are housed in DO-213AB MELF glass packages. The difference is packaging format: GL41GHE3/97 uses standard packaging while 1N6481-E3/96 is supplied in Tape & Reel format. Both maintain ROHS3 compliance and MSL 1 rating.

Q: What is the difference between BYM10-400-E3/96 and GL41GHE3/97?

A: Both parts are electrically and mechanically identical with one exception: BYM10-400-E3/96 is classified as Avalanche technology while GL41GHE3/97 uses Standard technology. All electrical parameters, package format (DO-213AB MELF), and compliance ratings are identical. The technology designation reflects internal device design but does not affect functional performance for the specified 400 V / 1 A application.

Q: Is the Microchip 1N5616US a suitable replacement?

A: The 1N5616US matches the 400 V reverse voltage and 1 A average rectified current ratings but introduces three significant differences: (1) different package format (SQ-MELF, A versus DO-213AB MELF) requiring PCB layout verification, (2) RoHS non-compliance versus ROHS3 compliance of the GL41GHE3/97, and (3) different electrical characteristics including 1.3 V forward voltage at 3 A and 500 nA reverse leakage. Selection requires design verification for package compatibility and regulatory compliance.

Q: What packaging formats are available for GL41GHE3/97 equivalents?

A: Vishay SUPERECTIFIER® equivalents are supplied in three packaging formats: Tape & Reel (TR) for 1N6481-E3/96, BYM10-400-E3/96, GL41G-E3/97, and GL41GHE3/96; Cut Tape & Digi-Reel® for GL41G-E3/96; and standard packaging for GL41GHE3/97. All use the same DO-213AB MELF glass package footprint and are compatible with automated assembly equipment.

Q: Are all Vishay substitutes ROHS3 compliant?

A: Yes. All Vishay SUPERECTIFIER® equivalents (1N6481-E3/96, BYM10-400-E3/96, GL41G-E3/96, GL41G-E3/97, GL41GHE3/96) maintain ROHS3 compliance. The Microchip 1N5616US is RoHS non-compliant and is not suitable for applications requiring ROHS3 certification.

Q: What is the operating temperature range for GL41GHE3/97?

A: The GL41GHE3/97 operates from -65°C to 175°C junction temperature. All Vishay SUPERECTIFIER® equivalents share this temperature range. The Microchip 1N5616US extends to 200°C, which may be advantageous in high-temperature applications but requires package compatibility verification.

Q: Can packaging format affect circuit performance?

A: Packaging format (Tape & Reel, Cut Tape & Digi-Reel®, or standard) does not affect electrical performance. Format selection is determined by assembly process requirements and inventory management. All formats use identical DO-213AB MELF glass packages with the same electrical characteristics and PCB footprint.
