Substitute Part Grouping Explanation

Substitution for the P6SMB6.8CAHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 5.8V (Typ)
• Voltage - Clamping: 10.5V (Max) @ Ipp
• Current - Peak Pulse: 57.1A (10/1000µs)
• Power - Peak Pulse: 600W
• Package: DO-214AA (SMB) surface mount
• Bidirectional configuration: 1 channel
• Operating temperature range: -65°C ~ 150°C
• Automotive grade with AEC-Q101 qualification
• RoHS3 compliance

Only parts matching all electrical specifications and mechanical packaging requirements qualify as direct substitutes. Packaging format variations (such as Tape & Reel versus bulk) do not affect electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB6.8CAHM3_B/I is the direct electrical and mechanical equivalent of the P6SMB6.8CAHM3_A/I. Both components share identical electrical specifications, automotive qualification, and compliance certifications.

The primary distinction is product status: the main part is Obsolete while the substitute is Active. For new designs or ongoing production requiring this TVS diode specification, the P6SMB6.8CAHM3_B/I provides continuity with current manufacturing support and supply availability.

The packaging format difference (Tape & Reel for the substitute versus bulk for the main part) does not affect electrical performance or circuit compatibility. Selection between these formats depends on assembly process requirements and volume considerations.

Frequently Asked Questions (FAQ)

Q: Can P6SMB6.8CAHM3_B/I replace P6SMB6.8CAHM3_A/I in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The substitute operates at the same voltage levels, current ratings, and temperature range with identical package dimensions (DO-214AA SMB).

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

A: The suffix designations (_A/I versus _B/I) indicate different manufacturing batches or packaging configurations. The electrical specifications and performance characteristics remain identical. The main part is Obsolete; the substitute is Active production.

Q: Does the Tape & Reel packaging of the substitute affect compatibility?

A: No. Tape & Reel is a packaging and delivery format for automated assembly processes. The component itself—its electrical performance, pinout, and physical dimensions—is identical to the bulk-packaged version.

Q: Are both parts automotive-grade with AEC-Q101 qualification?

A: Yes. Both the P6SMB6.8CAHM3_A/I and P6SMB6.8CAHM3_B/I carry automotive grade classification and AEC-Q101 qualification, meeting automotive reliability and quality standards.

Q: Is the substitute RoHS3 compliant?

A: Yes. The P6SMB6.8CAHM3_B/I is ROHS3 compliant, matching the compliance status of the original part.
