Engineering Selection Recommendations

The GBPC1502W from Fairchild Semiconductor is a qualified substitute for the obsolete MB152W. Selection is based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical voltage and current ratings (200 V, 15 A) with matching forward voltage characteristics (1.1 V @ 7.5 A). The GBPC1502W demonstrates superior reverse leakage performance (5 µA versus 10 µA), which provides operational margin in rectification circuits.

Temperature Performance: The GBPC1502W extends the lower operating temperature limit to -65°C compared to the MB152W's -55°C minimum, providing broader environmental compatibility without compromising the 150°C upper limit.

Product Status & Availability: The MB152W is classified as obsolete, while the GBPC1502W maintains active production status with documented inventory availability (1374 pcs), ensuring long-term procurement viability.

Compliance & Certifications: Both parts carry ROHS3 compliance and EAR99 ECCN classification, maintaining regulatory alignment for industrial applications.

Package Compatibility: Both components utilize 4-Square through-hole package geometry, enabling direct mechanical substitution in existing PCB layouts without redesign.

Frequently Asked Questions (FAQ)

Q: Can the GBPC1502W be used as a direct replacement for the MB152W in existing designs?

A: Yes. The GBPC1502W qualifies as a direct electrical and mechanical substitute. Both parts share identical voltage (200 V), current (15 A), and forward voltage (1.1 V @ 7.5 A) specifications. The through-hole 4-Square package geometry is compatible, permitting board-level substitution without layout modification.

Q: What are the key differences between these two parts?

A: The primary differences are product status and performance margins. The MB152W is obsolete; the GBPC1502W is in active production. The GBPC1502W exhibits lower reverse leakage current (5 µA versus 10 µA at 200 V) and an extended lower operating temperature limit (-65°C versus -55°C). These differences favor the GBPC1502W for new designs and long-term supply chain stability.

Q: Are there any package considerations when substituting these parts?

A: Both parts use 4-Square through-hole packages (MB-W and GBPC-W designations respectively). The physical form factors are compatible, and PCB footprints designed for the MB152W will accommodate the GBPC1502W without modification. Verify lead spacing and hole diameter specifications with component datasheets if custom footprints are used.

Q: What compliance certifications apply to the GBPC1502W?

A: The GBPC1502W carries ROHS3 compliance and EAR99 ECCN classification, matching the regulatory profile of the MB152W. Both parts are suitable for industrial applications requiring environmental and export compliance documentation.

Q: Why is the MB152W listed as obsolete?

A: The MB152W's obsolete status reflects discontinuation by Diodes Incorporated. The GBPC1502W provides functional and electrical equivalence with active manufacturing support, making it the recommended alternative for ongoing procurement and design continuity.
