Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4SMA68AHM3/H is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 58.1V
• Voltage - Breakdown (Min): 64.6V
• Voltage - Clamping (Max) @ Ipp: 92V
• Current - Peak Pulse (10/1000µs): 4.3A
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Unidirectional Channels: 1
• Type: Zener
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Automotive Grade and AEC-Q101 Qualification

The substitute part P4SMA68AHM3_A/H maintains identical electrical specifications and mechanical compatibility. The primary difference is packaging configuration (Tape & Reel versus standard packaging) and active product status, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The P4SMA68AHM3_A/H is a direct functional equivalent to the P4SMA68AHM3/H. Both parts maintain identical electrical performance specifications, automotive-grade qualification, and AEC-Q101 certification. The primary distinction is product status: the original part is discontinued, while the substitute remains in active production.

Selection of P4SMA68AHM3_A/H is appropriate for new designs and ongoing procurement. The Tape & Reel packaging configuration is standard for high-volume manufacturing and automated assembly processes. Both parts satisfy identical compliance requirements including ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can P4SMA68AHM3_A/H be used as a direct replacement for P4SMA68AHM3/H?

A: Yes. Both parts are identical in electrical specifications, mechanical package (DO-214AC, SMA), and automotive qualification. The substitute is currently in active production status.

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

A: The primary difference is packaging configuration. P4SMA68AHM3_A/H is supplied in Tape & Reel format, while P4SMA68AHM3/H uses standard packaging. Electrical performance and mechanical compatibility are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical automotive-grade classification, AEC-Q101 qualification, ROHS3 compliance, and REACH unaffected status.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: Voltage - Reverse Standoff (58.1V), Voltage - Breakdown (64.6V), Voltage - Clamping (92V), Current - Peak Pulse (4.3A), Power - Peak Pulse (400W), Package (DO-214AC, SMA), and Operating Temperature Range (-65°C ~ 150°C).

Q: Is the Tape & Reel packaging suitable for my application?

A: Tape & Reel packaging is standard for surface mount assembly and is compatible with automated pick-and-place equipment. The component itself is identical to the standard packaging variant.
