Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ160AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Unidirectional channel configuration (1 channel)
• Voltage - Reverse Standoff: 160V (typical)
• Voltage - Breakdown (Min): 178V
• Voltage - Clamping (Max) @ Ipp: 259V
• Current - Peak Pulse (10/1000µs): 2.3A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

The SMBJ160AHM3_B/I is classified as a manufacturer-recommended substitute. This part maintains identical electrical specifications and mechanical compatibility while differing only in product status (active versus obsolete) and packaging format (Tape & Reel versus unspecified for the original part).

Parameter Comparison

Engineering Selection Recommendations

The SMBJ160AHM3_B/I is the direct equivalent for the obsolete SMBJ160AHM3_A/I. Both parts are manufactured by Vishay and maintain identical electrical and mechanical specifications. The primary distinction is product lifecycle status: the SMBJ160AHM3_A/I is obsolete, while the SMBJ160AHM3_B/I is active and currently in production.

Both parts carry automotive-grade qualification (AEC-Q101) and ROHS3 compliance, ensuring suitability for regulated applications. The SMBJ160AHM3_B/I is available in Tape & Reel packaging format, which is standard for high-volume manufacturing and automated assembly processes.

For new designs or production continuity, the SMBJ160AHM3_B/I is the appropriate selection. Existing designs using the SMBJ160AHM3_A/I can transition to the SMBJ160AHM3_B/I without circuit modification, as all functional and mechanical parameters are identical.

Frequently Asked Questions (FAQ)

Q: Can the SMBJ160AHM3_B/I be used as a direct replacement for the SMBJ160AHM3_A/I?

A: Yes. Both parts are identical in electrical performance, voltage ratings, current handling, temperature range, and package configuration. The SMBJ160AHM3_B/I is the active production equivalent.

Q: What is the difference between the SMBJ160AHM3_A/I and SMBJ160AHM3_B/I?

A: The primary difference is product status. The SMBJ160AHM3_A/I is obsolete, while the SMBJ160AHM3_B/I is active. The SMBJ160AHM3_B/I is supplied in Tape & Reel packaging. All electrical and mechanical specifications are identical.

Q: Are both parts suitable for automotive applications?
