Substitute Part Grouping Explanation

Substitution of the P6SMB160AHE3_A/I is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 136V
• Voltage - Breakdown (Min): 152V
• Voltage - Clamping (Max) @ Ipp: 219V
• Current - Peak Pulse (10/1000µs): 2.7A
• Power - Peak Pulse: 600W
• Unidirectional Channels: 1
• Type: Zener

Mechanical Parameters (Must Match):

• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount

Compliance & Certification (Must Match):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

The P6SMB160AHE3_B/I meets all substitution criteria as an active product within the same P6SMB TransZorb® series, maintaining identical electrical specifications and automotive-grade certifications.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB160AHE3_B/I is the direct substitute for the obsolete P6SMB160AHE3_A/I. Both components are manufactured by Vishay within the same P6SMB TransZorb® series and maintain identical electrical and mechanical specifications. The substitute part carries active product status, ensuring continued availability and manufacturing support.

Both parts satisfy automotive-grade requirements with AEC-Q101 qualification and ROHS3 compliance, meeting regulatory and environmental standards for automotive applications. The transition from the obsolete variant to the active substitute presents no functional or compliance risk in circuit design.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB160AHE3_B/I be used as a direct replacement for the P6SMB160AHE3_A/I?

A: Yes. Both parts are electrically and mechanically identical, with matching voltage ratings (136V standoff, 219V clamping), current specifications (2.7A peak pulse), and power dissipation (600W). Both are housed in the DO-214AA (SMB) surface mount package and carry identical automotive certifications.

Q: What is the difference between the _A/I and _B/I variants?

A: The primary difference is product status. The P6SMB160AHE3_A/I is obsolete, while the P6SMB160AHE3_B/I is active. The _B/I variant is supplied in Tape & Reel (TR) packaging format. All electrical and mechanical parameters remain equivalent.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. Both parts use the identical DO-214AA (SMB) surface mount package. PCB footprints, solder pad layouts, and mounting procedures are identical. No design modifications are required.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the P6SMB160AHE3_A/I and P6SMB160AHE3_B/I carry automotive-grade classification with AEC-Q101 qualification, meeting automotive industry reliability and quality standards.

Q: Is the substitute part ROHS compliant?

A: Yes. The P6SMB160AHE3_B/I is ROHS3 compliant and REACH unaffected, matching the compliance status of the original part.
