Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB10CAHM3_A/I is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 8.55V
• Voltage - Breakdown (Min): 9.5V
• Voltage - Clamping (Max) @ Ipp: 14.5V
• Current - Peak Pulse (10/1000µs): 41.4A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Bidirectional Channels: 1
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Automotive Grade and AEC-Q101 Qualification

The P6SMB10CAHM3_B/I is the manufacturer-recommended substitute, maintaining identical electrical performance specifications and package configuration while offering active product status.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB10CAHM3_B/I is the direct equivalent for the obsolete P6SMB10CAHM3_A/I. Both parts maintain identical electrical specifications, automotive-grade qualification, and AEC-Q101 certification. The primary distinction is product status: the substitute is active and available through standard procurement channels, while the original part is obsolete.

For new designs or production continuity, the P6SMB10CAHM3_B/I should be selected. Both parts are ROHS3 compliant and carry MSL 1 rating, ensuring compatibility with standard surface mount assembly processes. The packaging difference (bulk versus Tape & Reel) does not affect electrical or mechanical compatibility and is a procurement consideration only.

Frequently Asked Questions (FAQ)

Q: Can P6SMB10CAHM3_B/I be used as a direct replacement for P6SMB10CAHM3_A/I?

A: Yes. Both parts are electrically and mechanically identical, with matching voltage ratings (8.55V standoff, 14.5V clamping), current handling (41.4A peak pulse), power dissipation (600W), and package configuration (DO-214AA SMB). The substitute is the manufacturer-recommended equivalent.

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

A: The primary difference is product status. P6SMB10CAHM3_A/I is obsolete, while P6SMB10CAHM3_B/I is active. The suffix designations (_A/I versus _B/I) indicate manufacturing or qualification variants, but electrical performance is identical.

Q: Are there packaging differences between these parts?

A: The main part is supplied in bulk packaging, while the substitute is available in Tape & Reel (TR) format. This is a procurement and assembly convenience difference with no impact on component functionality or performance.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both P6SMB10CAHM3_A/I and P6SMB10CAHM3_B/I carry automotive grade classification and AEC-Q101 qualification, making them suitable for automotive telecom applications.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution is based on matching reverse standoff voltage (8.55V), breakdown voltage (9.5V minimum), clamping voltage (14.5V maximum at peak pulse current), peak pulse current (41.4A), and power dissipation (600W). All parameters are identical between the main part and substitute.
