GP02-40-M3/73 Equivalent & Substitute Parts

Part Overview

The GP02-40-M3/73 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This through-hole component operates at 4000 V DC reverse voltage with 250 mA average rectified current in a DO-204AL (DO-41) axial package. The part is classified as obsolete, necessitating identification of active equivalent alternatives for continued circuit implementation and procurement.

Substitute Part Grouping Explanation

Substitution of the GP02-40-M3/73 is determined by electrical and mechanical parameter equivalence within the GP02 base product family. All substitute parts maintain identical specifications across the following critical parameters:

Voltage - DC Reverse (Vr) (Max): 4000 V
Current - Average Rectified (Io): 250 mA
Voltage - Forward (Vf) (Max) @ If: 3 V @ 1 A
Reverse Recovery Time (trr): 2 µs
Current - Reverse Leakage @ Vr: 5 µA @ 4000 V
Package / Case: DO-204AL, DO-41, Axial
Mounting Type: Through Hole
Operating Temperature - Junction: -65°C ~ 175°C

Substitute parts differ in product status (active versus obsolete), packaging format (cut tape versus bulk), and series designation, but maintain full electrical and mechanical compatibility for direct circuit substitution.

Engineering Selection Recommendations

GP02-40-E3/73 is the manufacturer-recommended substitute for the obsolete GP02-40-M3/73. This part maintains full electrical and mechanical equivalence while offering active product status and improved supply availability (4300 pcs in stock). The GP02-40-E3/73 is designated as part of the SUPERECTIFIER® series and is supplied in cut tape packaging format, suitable for automated assembly processes.

GP02-40-E3/53 serves as a parametric equivalent alternative, providing identical electrical specifications and active product status with 720 pcs available in inventory. This part differs only in packaging designation suffix and maintains all critical performance parameters required for direct circuit substitution.

Both substitute parts comply with ROHS3 and REACH regulatory requirements, matching the compliance profile of the original component. Selection between GP02-40-E3/73 and GP02-40-E3/53 should be based on packaging format requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can GP02-40-E3/73 and GP02-40-E3/53 be used interchangeably with GP02-40-M3/73?

A: Yes. Both substitute parts maintain identical electrical parameters (4000 V reverse voltage, 250 mA average rectified current, 3 V forward voltage, 2 µs reverse recovery time, 5 µA reverse leakage) and mechanical specifications (DO-204AL axial through-hole package, -65°C to 175°C operating range). Direct substitution is supported without circuit modification.

Q: What is the difference between GP02-40-E3/73 and GP02-40-E3/53?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference lies in the packaging designation suffix. GP02-40-E3/73 is supplied in cut tape format, while GP02-40-E3/53 uses standard packaging. Selection depends on assembly process requirements and procurement preferences.

Q: Why is the original GP02-40-M3/73 classified as obsolete?

A: The GP02-40-M3/73 has been discontinued by the manufacturer. Active alternatives within the GP02 product family provide equivalent performance and are recommended for new designs and ongoing procurement.

Q: Are there any compliance differences between the original and substitute parts?

A: No. All parts maintain identical RoHS3 compliance and REACH unaffected status. Regulatory and environmental compliance requirements are fully satisfied by both substitute options.

Q: What packaging formats are available for these diodes?

A: All three parts use the DO-204AL (DO-41) axial through-hole package. GP02-40-E3/73 is available in cut tape format for automated assembly, while GP02-40-E3/53 uses standard packaging. The original GP02-40-M3/73 packaging format is not specified in available documentation.
