Substitute Part Grouping Explanation

Substitute parts for the BYM07-400HE3_A/I are determined by strict equivalence across the following critical parameters:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 500 mA
• Voltage - Forward (Vf) (Max) @ If: 1.35 V @ 500 mA
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 400 V
• Capacitance @ Vr, F: 7 pF @ 4V, 1MHz
• Package / Case: DO-213AA (Glass)
• Operating Temperature - Junction: -65°C ~ 175°C
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS Status: ROHS3 Compliant

All identified substitute parts maintain identical electrical performance specifications and package configuration. Differences in packaging format (Tape & Reel versus other formats) and inventory levels do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and are manufactured by Vishay General Semiconductor - Diodes Division. Each part is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

The BYM07-400HE3_A/I differs from substitute parts primarily in packaging format. The main part is supplied in standard packaging, while BYM07-400-E3/98, EGL34G-E3/83, and EGL34G-E3/98 are supplied in Tape & Reel (TR) format. This distinction affects supply chain logistics and automated assembly processes but does not alter electrical performance or functional compatibility.

All parts are qualified to AEC-Q101 automotive standards where applicable and operate across the identical temperature range of -65°C to 175°C junction temperature. Selection between equivalent parts should be based on packaging requirements, inventory availability, and supply chain specifications rather than electrical performance criteria.

Frequently Asked Questions (FAQ)

Q: Can BYM07-400-E3/98 be used as a direct replacement for BYM07-400HE3_A/I?

A: Yes. Both parts are electrically identical with matching voltage ratings (400 V), current ratings (500 mA), forward voltage (1.35 V @ 500 mA), and reverse recovery time (50 ns). The primary difference is packaging format: BYM07-400-E3/98 is supplied in Tape & Reel format while BYM07-400HE3_A/I uses standard packaging. Functional performance in the circuit is equivalent.

Q: What is the difference between BYM07 and EGL34 base product numbers?

A: BYM07 and EGL34 are different base product designations from Vishay General Semiconductor - Diodes Division. However, the substitute parts EGL34G-E3/83 and EGL34G-E3/98 maintain identical electrical specifications to BYM07-400HE3_A/I across all critical parameters including voltage, current, forward voltage, and recovery time. The base product number difference reflects internal Vishay product line organization but does not indicate functional differences.

Q: Are all substitute parts suitable for automotive applications?

A: The main part BYM07-400HE3_A/I carries AEC-Q101 automotive qualification. All substitute parts are Active status products from Vishay General Semiconductor - Diodes Division and meet ROHS3 and REACH compliance requirements. Specific automotive qualification status for each substitute part should be confirmed through the manufacturer's documentation if automotive certification is a design requirement.

Q: What does Tape & Reel (TR) packaging mean?

A: Tape & Reel packaging is a standard format for surface mount components used in automated assembly processes. Components are wound on a continuous tape and reel for high-speed pick-and-place machine compatibility. This differs from other packaging formats but does not affect the electrical characteristics or performance of the diode itself.

Q: Can I mix different substitute parts in the same production run?

A: All substitute parts maintain identical electrical specifications and package configuration (DO-213AA Glass). From an electrical standpoint, mixing parts is functionally equivalent. However, supply chain and manufacturing process considerations may apply depending on your organization's quality and traceability requirements.

Q: What is the significance of the 50 ns reverse recovery time?

A: The 50 ns reverse recovery time classifies this diode as a fast recovery rectifier. This specification determines the diode's switching speed and is critical in high-frequency applications. All substitute parts maintain this identical specification, ensuring equivalent performance in circuits where switching speed is a design parameter.

Q: Are there any temperature-related differences between substitute parts?

A: No. All parts operate across the identical junction temperature range of -65°C to 175°C. Temperature performance is equivalent across all substitute options.
