Engineering Selection Recommendations

BAV170-7-F (Diodes Incorporated) — Active Status

This substitute meets all mandatory electrical and mechanical parameters with the exception of current rating. The BAV170-7-F is rated for 125 mA average rectified current, which is below the 215 mA specification of the 1PS184,115. This part is suitable only for applications where the actual operating current does not exceed 125 mA. The part is in Active production status with unlimited availability and full RoHS3 compliance.

BAV170-TP (Micro Commercial Co) — Active Status

This substitute meets all mandatory electrical and mechanical parameters. The BAV170-TP is rated for 85 V DC reverse voltage and 215 mA average rectified current, matching the current capacity of the 1PS184,115. Forward voltage is 1.25 V @ 150 mA. The part is in Active production status with full RoHS3 compliance and MSL 1 rating.

BAV70,215 (Nexperia USA Inc.) — Active Status

This substitute exceeds all mandatory electrical and mechanical parameters. The BAV70,215 is rated for 100 V DC reverse voltage and 215 mA average rectified current. Reverse recovery time is 4 ns, matching the fast recovery characteristic of the 1PS184,115. The part is in Active production status with full RoHS3 compliance and MSL 1 rating. Higher voltage rating provides additional design margin.

BAV70E6433HTMA1 (Infineon Technologies) — Last Time Buy Status

This substitute meets all mandatory electrical and mechanical parameters. The BAV70E6433HTMA1 is rated for 80 V DC reverse voltage and 200 mA average rectified current. Current rating is 200 mA, which is below the 215 mA specification of the 1PS184,115. The part is in Last Time Buy status, indicating limited future availability. Full RoHS3 compliance and MSL 1 rating are maintained.

Recommended Primary Substitutes:

For new designs and ongoing procurement, BAV170-TP or BAV70,215 are the preferred substitutes. Both parts are in Active production status, meet or exceed all electrical specifications, and maintain full compliance certifications. BAV70,215 provides the highest voltage margin at 100 V.

Frequently Asked Questions (FAQ)

Q: Can BAV170-7-F be used as a direct replacement for 1PS184,115?

A: BAV170-7-F is not a direct replacement. While it matches the package, configuration, and most electrical parameters, it is rated for only 125 mA average rectified current compared to the 215 mA specification of the 1PS184,115. Use this part only if your application current does not exceed 125 mA.

Q: What is the difference between BAV170-TP and BAV70,215?

A: Both parts meet the 215 mA current requirement. BAV170-TP is rated for 85 V DC reverse voltage, while BAV70,215 is rated for 100 V. BAV70,215 provides higher voltage margin. Both are in Active production status. Selection depends on your specific voltage and availability requirements.

Q: Why is BAV70E6433HTMA1 marked as Last Time Buy?

A: Last Time Buy status indicates that Infineon Technologies has announced the end of production for this part. While current inventory is available (48,132 pieces), future procurement will not be possible. This part should be considered only for short-term applications or as a temporary solution.

Q: Are all substitute parts pin-compatible with 1PS184,115?

A: Yes. All substitute parts use the same TO-236-3 (SC-59, SOT-23-3) package with identical pinout for 1 Pair Common Cathode diode array configuration. No PCB layout changes are required.

Q: Do all substitutes meet RoHS3 compliance?

A: Yes. All four substitute parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the 1PS184,115.

Q: What is the impact of different reverse recovery times?

A: The 1PS184,115 and BAV70,215 both have 4 ns reverse recovery time (fast recovery). BAV170-7-F, BAV170-TP, and BAV70E6433HTMA1 have 3 µs or 4 ns recovery times. In high-frequency switching applications, verify that the substitute part's recovery time meets your circuit requirements.

Q: Which substitute has the best long-term availability?

A: BAV170-TP and BAV70,215 are both in Active production status, ensuring long-term availability. BAV70E6433HTMA1 is Last Time Buy and should not be selected for new designs requiring extended component life.
