Substitute Part Grouping Explanation

Substitution eligibility for the BAV99DW-7 is determined by the following critical parameters:

Primary Substitution Criteria:

Diode configuration (2 Pair Series Connection)
Package type (6-TSSOP, SC-88, SOT-363)
Voltage rating (DC reverse voltage capability)
Current rating (average rectified current per diode)
Reverse recovery time (4 ns)
Operating temperature range (-65°C ~ 150°C minimum)

Substitution Categories:

Direct Equivalents maintain all electrical parameters identical to the BAV99DW-7 (75 V, 215 mA, 4 ns trr) with identical package specifications. These parts differ only in packaging format (tape & reel versus cut tape) or compliance status.

Parametric Equivalents maintain core electrical specifications (75 V, 215 mA, 4 ns trr) but include additional qualifications such as automotive-grade certification (AEC-Q101).

Functional Alternatives provide the same diode configuration and package but with modified electrical parameters (voltage or current ratings) that remain within acceptable application ranges. These parts are suitable only when the application circuit tolerates the parameter variations.

Engineering Selection Recommendations

Primary Recommendation: BAV99DW-7-F

The BAV99DW-7-F is the direct functional equivalent of the BAV99DW-7, manufactured by Diodes Incorporated. This part maintains identical electrical specifications (75 V, 215 mA, 4 ns reverse recovery time) and package configuration. The BAV99DW-7-F is currently in active production with substantial inventory availability (205,400 units). This part achieves ROHS3 compliance, addressing regulatory requirements that the original BAV99DW-7 does not meet. The BAV99DW-7-F is available in Cut Tape and Digi-Reel packaging formats, providing flexibility for both prototype and production procurement.

Secondary Recommendation: BAV99DWQ-7-F

The BAV99DWQ-7-F provides identical electrical performance to the BAV99DW-7 with the addition of automotive-grade qualification (AEC-Q101). This part is suitable for applications requiring automotive-level reliability and traceability. The BAV99DWQ-7-F is supplied in Tape & Reel packaging and maintains ROHS3 compliance. Inventory availability is 28,660 units.

Functional Alternative: BAV99DW-TP

The BAV99DW-TP, manufactured by Micro Commercial Co, provides the same diode configuration and package but with reduced current rating (150 mA versus 215 mA). This part is suitable only for applications where the circuit current requirement does not exceed 150 mA per diode. The operating temperature range is limited to -55°C minimum (versus -65°C for the BAV99DW-7). This part is ROHS3 compliant and currently active.

Functional Alternative: CMKD7000 TR PBFREE

The CMKD7000 TR PBFREE, manufactured by Central Semiconductor Corp, provides the same diode configuration and package but with elevated voltage rating (100 V versus 75 V) and reduced current rating (200 mA versus 215 mA). The reverse leakage current is significantly lower (500 nA @ 100 V versus 2.5 µA @ 75 V). This part is suitable for applications where higher voltage margin is required and current demand does not exceed 200 mA per diode. The part is ROHS3 compliant and currently active with substantial inventory (33,066 units).

Frequently Asked Questions (FAQ)

Q: Can BAV99DW-7-F be used as a direct replacement for BAV99DW-7?

A: Yes. The BAV99DW-7-F maintains identical electrical specifications and package configuration. The primary differences are packaging format (available in both Cut Tape and Digi-Reel) and improved RoHS compliance status (ROHS3 versus non-compliant). No circuit modifications are required.

Q: What is the difference between BAV99DW-7-F and BAV99DWQ-7-F?

A: Both parts are manufactured by Diodes Incorporated and maintain identical electrical specifications (75 V, 215 mA, 4 ns trr). The BAV99DWQ-7-F includes automotive-grade qualification (AEC-Q101) and is supplied in Tape & Reel packaging only. The BAV99DW-7-F is available in both Cut Tape and Digi-Reel formats. Selection depends on application requirements and packaging preferences.

Q: Can BAV99DW-TP be used in place of BAV99DW-7?

A: BAV99DW-TP is suitable only if the application circuit current requirement does not exceed 150 mA per diode. The BAV99DW-7 is rated for 215 mA, so BAV99DW-TP represents a downgrade in current capacity. Additionally, the minimum operating temperature is -55°C (versus -65°C for BAV99DW-7). Use only when application specifications accommodate these limitations.

Q: What are the advantages of CMKD7000 TR PBFREE over BAV99DW-7?

A: The CMKD7000 TR PBFREE provides higher voltage rating (100 V versus 75 V) and significantly lower reverse leakage current (500 nA @ 100 V versus 2.5 µA @ 75 V). These characteristics are beneficial for applications requiring higher voltage margin or lower leakage performance. The current rating is reduced to 200 mA (versus 215 mA), which is acceptable for most applications but represents a minor downgrade.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts use the 6-TSSOP, SC-88, SOT-363 package. Pinout and footprint compatibility are maintained across all alternatives. Packaging format (Cut Tape, Digi-Reel, or Tape & Reel) varies by part number and supplier.

Q: Which substitute part should be selected for new designs?

A: For new designs, BAV99DW-7-F is the recommended choice. It provides direct electrical equivalence to BAV99DW-7, is currently in active production, and achieves ROHS3 compliance. For automotive applications, BAV99DWQ-7-F is recommended due to AEC-Q101 qualification. For applications requiring higher voltage margin, CMKD7000 TR PBFREE is suitable if current requirements do not exceed 200 mA.

Q: What is the inventory status of each substitute part?

A: BAV99DW-7-F has the highest availability (205,400 units). CMKD7000 TR PBFREE has 33,066 units. BAV99DWQ-7-F has 28,660 units. BAV99DW-TP has 2,151 units. All parts are currently in active production status.
