All substitute parts listed maintain identical electrical specifications and are compatible with the same PCB footprint and assembly processes. Differences in packaging format (Tape & Box versus Tape & Reel) and manufacturer do not affect functional performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet Active product status and RoHS compliance requirements. The P6SMB170A-M3/52 (Vishay) and SMBJP6KE170A-TP (Micro Commercial Co) are both ROHS3 compliant. The P6SMB170A (Eaton) carries RoHS compliance certification. Selection between these parts should be based on availability, packaging format preference (Tape & Box versus Tape & Reel), and supply chain requirements. The Eaton variant operates across a narrower minimum temperature range (-55°C versus -65°C), which may be a consideration for applications requiring extended low-temperature performance.

Frequently Asked Questions (FAQ)

Q: Can SMBJP6KE170A-TP be used as a direct replacement for P6SMB170A-M3/52?

A: Yes. Both parts share identical electrical specifications including voltage ratings, clamping voltage, peak pulse current, and power dissipation. Both are housed in DO-214AA (SMB) surface mount packages. The primary difference is packaging format: P6SMB170A-M3/52 uses Tape & Box while SMBJP6KE170A-TP uses Tape & Reel.

Q: What is the difference between the Eaton P6SMB170A and the Vishay P6SMB170A-M3/52?

A: Electrical performance is identical across all rated parameters. The Eaton variant specifies a minimum operating temperature of -55°C compared to -65°C for the Vishay part. Both are RoHS compliant and use the same DO-214AA (SMB) package.

Q: Are there any compatibility issues when substituting these parts on existing PCBs?

A: No. All substitute parts use the identical DO-214AA (SMB) footprint and are compatible with existing PCB designs and assembly processes.

Q: Which substitute part should be selected for high-volume production?

A: Selection should be based on current inventory levels and lead times. The Eaton P6SMB170A shows higher inventory availability (41,300 pcs) compared to other variants, which may provide supply chain advantages for high-volume applications.

Q: Do these parts have different moisture sensitivity requirements?

A: No. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
