Substitute Part Grouping Explanation

Substitution of the BAV74_D87Z is determined by the following critical parameters:

Electrical Parameters:

Diode configuration (1 pair common cathode)
Maximum reverse voltage (50 V minimum)
Average rectified current per diode (200 mA minimum)
Forward voltage characteristics
Reverse recovery time
Reverse leakage current

Mechanical Parameters:

Surface mount mounting type
SOT-23-3 package compatibility (TO-236-3, SC-59)

Environmental Parameters:

Operating temperature range
Moisture sensitivity level

Substitute parts are grouped into two categories: Direct Equivalents (identical electrical and mechanical specifications) and Parametric Equivalents (meet or exceed all critical electrical parameters within the same package).

Frequently Asked Questions (FAQ)

Q: Can BAV74LT1G be used as a direct replacement for BAV74_D87Z?

A: Yes. BAV74LT1G is a direct electrical and mechanical equivalent with identical reverse voltage (50 V), rectified current (200 mA), forward voltage (1 V @ 100 mA), and reverse recovery time (4 ns). Both use SOT-23-3 packaging. BAV74LT1G has active product status and extended temperature range.

Q: What is the difference between BAV74,215 and BAV74_D87Z?

A: BAV74,215 has a higher average rectified current rating of 215 mA per diode compared to 200 mA for BAV74_D87Z. All other electrical parameters are identical. BAV74,215 is suitable for applications requiring additional current margin.

Q: Is BAV70-E3-08 a suitable replacement?

A: BAV70-E3-08 is not a direct replacement. It has higher reverse voltage (70 V vs. 50 V), higher current rating (250 mA vs. 200 mA), higher forward voltage (1.25 V @ 150 mA vs. 1 V @ 100 mA), and different reverse leakage characteristics (50 µA @ 70 V vs. 100 nA @ 50 V). Use only if your application requires higher voltage/current ratings and can tolerate increased forward voltage drop.

Q: Are all substitute parts RoHS compliant?

A: BAV74LT1G, BAV74,215, BAV74,235, and BAV74-TP are RoHS3 compliant. BAV74 (Fairchild Semiconductor) has undefined RoHS status. All parts are REACH unaffected.

Q: What is the difference in packaging between the substitute parts?

A: All substitute parts use SOT-23-3 package (TO-236-3, SC-59). Packaging variations exist only in supplier device package designations and tape/reel configurations, which do not affect electrical or mechanical compatibility.

Q: Which substitute part has the best inventory availability?

A: BAV74 (Fairchild Semiconductor) has the highest inventory with 2,183,200 pcs available. BAV74LT1G (onsemi) has 107,400 pcs. Other substitutes have lower inventory levels.

Q: Can I use BAV74-TP in place of BAV74_D87Z?

A: Yes. BAV74-TP is a direct electrical equivalent with identical specifications. It has active product status, extended operating temperature range (-55°C to 150°C), and RoHS3 compliance.
