Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS70WQ-7-F is determined by strict equivalence across the following parameters:

• Voltage Rating: DC reverse voltage must equal 70 V maximum
• Current Rating: Average rectified current must equal 70 mA
• Forward Voltage: Maximum forward voltage must equal 1 V at 15 mA
• Reverse Recovery Time: Must equal 5 ns
• Reverse Leakage Current: Must equal 100 nA at 50 V
• Package Type: Must be SC-70 / SOT-323 surface mount
• Operating Temperature Range: Must span -55°C to 125°C junction temperature
• Technology: Must be Schottky diode
• Compliance: Must maintain ROHS3 compliance and REACH Unaffected status

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in manufacturer, inventory availability, or moisture sensitivity level do not affect substitution eligibility when electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

BAS70W-7-F (Diodes Incorporated): This part is a direct parametric equivalent to the BAS70WQ-7-F. Both are manufactured by Diodes Incorporated and share identical electrical specifications, package type, and compliance certifications. The BAS70W-7-F carries higher inventory availability (19,521 units) and includes specified moisture sensitivity level (MSL 1 - Unlimited). Selection of this substitute is appropriate for applications requiring equivalent performance with enhanced supply chain availability.

BAS70WT-TP (Micro Commercial Co): This part is a direct parametric equivalent manufactured by Micro Commercial Co. All critical electrical parameters, package type, operating temperature range, and compliance certifications match the BAS70WQ-7-F specification. The capacitance parameter is not specified for this part; however, this does not affect substitution eligibility as the core functional parameters remain equivalent. Inventory availability is 3,100 units. This substitute is suitable for applications where multi-source component qualification is required or when Diodes Incorporated supply is constrained.

Both substitute parts maintain Active product status and full compliance with ROHS3 and REACH requirements, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can BAS70W-7-F be used as a direct replacement for BAS70WQ-7-F?

A: Yes. Both parts are Schottky diodes with identical voltage ratings (70 V), current ratings (70 mA), forward voltage characteristics (1 V @ 15 mA), reverse recovery time (5 ns), and reverse leakage current (100 nA @ 50 V). Both use SC-70 / SOT-323 packaging and operate across -55°C to 125°C. Electrical and mechanical compatibility is complete.

Q: What is the difference between BAS70WQ-7-F and BAS70W-7-F?

A: The primary difference is manufacturer designation within the Diodes Incorporated product line. Both parts share identical electrical specifications, package type, and compliance status. The BAS70W-7-F has higher inventory availability and includes specified moisture sensitivity level (MSL 1).

Q: Can BAS70WT-TP from Micro Commercial Co replace BAS70WQ-7-F?

A: Yes. The BAS70WT-TP meets all electrical parameter requirements: 70 V reverse voltage, 70 mA current rating, 1 V forward voltage at 15 mA, 5 ns reverse recovery time, and 100 nA reverse leakage current. Package type (SOT-323) and operating temperature range (-55°C to 125°C) are identical. Multi-manufacturer substitution is valid when all parameters align.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. All three parts use the SC-70 / SOT-323 surface mount package. PCB footprint, lead spacing, and mounting requirements are identical. No layout or assembly modifications are required.

Q: Do all substitute parts meet automotive qualification requirements?

A: The BAS70WQ-7-F carries AEC-Q101 automotive qualification. The BAS70W-7-F and BAS70WT-TP are specified as Active products with ROHS3 compliance and REACH Unaffected status. Automotive qualification status for substitute parts should be confirmed with the respective manufacturer if AEC-Q101 certification is a design requirement.

Q: What is the significance of the capacitance specification not being listed for BAS70WT-TP?

A: The BAS70WT-TP does not include a specified capacitance value, whereas the BAS70WQ-7-F and BAS70W-7-F specify 2 pF @ 0V, 1MHz. This does not affect substitution eligibility for standard rectification applications. Applications requiring precise capacitance control should reference the Micro Commercial Co datasheet or contact the manufacturer for this parameter.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: All three parts are classified as Small Signal diodes with reverse recovery time of 5 ns, suitable for high-frequency applications. Electrical characteristics are equivalent across all specified parameters. Interchangeability is supported by the matching specifications.
