W02G Bridge Rectifier Single Phase 200V 1.5A Equivalent & Substitute Parts

Part Overview

The W02G is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division, rated for 200V peak reverse voltage and 1.5A average rectified current. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The W02G operates across a temperature range of -55°C to 150°C and is housed in a 4-Circular WOG package for through-hole mounting applications.

Substitute Part Grouping Explanation

Substitution for the W02G is determined by the following critical parameters: single-phase diode type, standard technology, 200V peak reverse voltage rating, through-hole mounting configuration, and compatible package form factor. Substitute parts must maintain electrical equivalence across these core specifications to ensure functional interchangeability in the target application.

The W02G has two identified substitutes:

Parametric Equivalent (W02G-E4/51): Maintains identical electrical specifications and package type, differing only in product status (active vs. obsolete) and compliance certifications.

Manufacturer Recommended Substitute (GBU2502-G): Provides higher current capacity (4.2A vs. 1.5A) while maintaining the 200V voltage rating and through-hole mounting. This substitute accommodates applications requiring increased current handling within the same voltage class.

Engineering Selection Recommendations

W02G-E4/51 is the direct parametric equivalent and primary substitute. It maintains identical electrical performance and package configuration while offering active product status and ROHS3 compliance. This part is suitable for direct replacement in existing designs without circuit modification.

GBU2502-G is the manufacturer-recommended alternative for applications requiring higher current capacity. The 4.2A rating provides increased design margin compared to the 1.5A specification of the W02G. However, the GBU package form factor differs from the WOG package, requiring PCB layout verification for mechanical fit. This substitute is appropriate when current requirements exceed 1.5A within the 200V voltage class.

Both substitutes are active products with current manufacturing support and ROHS3 compliance, providing long-term supply chain stability compared to the obsolete W02G.

Frequently Asked Questions (FAQ)

Q: Can W02G-E4/51 be used as a direct drop-in replacement for W02G?

A: Yes. W02G-E4/51 maintains identical electrical specifications (200V, 1.5A, forward voltage, reverse leakage) and package configuration (4-Circular WOG). No circuit design changes are required.

Q: What is the primary difference between W02G-E4/51 and the original W02G?

A: The W02G-E4/51 is an active product with ROHS3 compliance and MSL rating, whereas the W02G is obsolete and RoHS non-compliant. Electrical performance is identical.

Q: When should GBU2502-G be selected instead of W02G-E4/51?

A: GBU2502-G should be selected when the application requires current capacity exceeding 1.5A. The GBU2502-G is rated for 4.2A average rectified current at the same 200V voltage rating. PCB layout must accommodate the different GBU package form factor.

Q: Are there package compatibility considerations between WOG and GBU packages?

A: Yes. WOG and GBU are different through-hole package form factors. While both are 4-pin configurations for single-phase bridge rectifiers, physical dimensions and pin spacing differ. PCB footprint verification is required before substituting GBU2502-G for W02G or W02G-E4/51.

Q: What compliance certifications apply to each substitute?

A: W02G-E4/51 and GBU2502-G are both ROHS3 compliant with MSL rating of 1 (Unlimited). The original W02G is RoHS non-compliant. Both substitutes meet REACH and EAR99 classifications.

Q: Is current derating necessary when using GBU2502-G in place of W02G?

A: No derating is necessary. GBU2502-G has a higher current rating (4.2A) than the W02G (1.5A), providing additional design margin. Applications designed for 1.5A operation remain within safe operating limits.
