Substitute Part Grouping Explanation

Substitution of the P6SMB150AHM3_A/I is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 128V
• Voltage - Breakdown (Min): 143V
• Voltage - Clamping (Max) @ Ipp: 207V
• Current - Peak Pulse (10/1000µs): 2.9A
• Power - Peak Pulse: 600W
• Operating Temperature Range: -65°C to 150°C
• Package / Case: DO-214AA (SMB)
• Unidirectional Channels: 1
• Type: Zener
• Series: P6SMB, TransZorb®
• Grade: Automotive
• Qualification: AEC-Q101

The P6SMB150AHM3_B/I is the manufacturer-recommended substitute, maintaining identical electrical performance and mechanical compatibility while offering active product status and improved supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB150AHM3_B/I is the direct equivalent for the obsolete P6SMB150AHM3_A/I. Both components maintain identical electrical specifications, thermal operating range, and automotive-grade AEC-Q101 qualification. The primary distinction is product status: the substitute part is currently active in production, ensuring long-term availability and supply chain continuity. Both parts comply with ROHS3 and REACH requirements. For new designs or component replenishment, the P6SMB150AHM3_B/I is the appropriate selection. The packaging difference (Tape & Reel for the substitute versus unspecified for the main part) does not affect electrical or mechanical compatibility and reflects standard manufacturing practices for active products.

Frequently Asked Questions (FAQ)

Q: Can P6SMB150AHM3_B/I be used as a direct replacement for P6SMB150AHM3_A/I?

A: Yes. Both parts are identical in electrical performance, thermal characteristics, and mechanical package. The substitute is the manufacturer-recommended alternative and is currently in active production.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. The P6SMB150AHM3_A/I is obsolete, while the P6SMB150AHM3_B/I is active. The suffix designation (_A/I versus _B/I) indicates manufacturing revision. Electrical and mechanical specifications remain equivalent.

Q: Are there any packaging compatibility concerns?

A: No. Both parts use the DO-214AA (SMB) surface mount package. The substitute is supplied in Tape & Reel format, which is standard for active production components and does not affect PCB assembly compatibility.

Q: Does the substitute meet automotive qualification requirements?

A: Yes. The P6SMB150AHM3_B/I maintains AEC-Q101 automotive qualification and is graded for automotive applications, identical to the original part.

Q: What is the inventory status for each part?

A: The P6SMB150AHM3_A/I has 1131 pieces in stock (obsolete status). The P6SMB150AHM3_B/I has 679 pieces in stock (active status). For ongoing procurement, the active substitute is recommended.
