BAS40CW_R1_00001 Equivalent & Substitute Parts

Part Overview

The BAS40CW_R1_00001 is a Schottky diode array manufactured by Panjit International Inc., configured as a 1 Pair Common Cathode arrangement rated for 40 V DC reverse voltage and 200 mA average rectified current per diode. The device is housed in a surface mount SC-70, SOT-323 package and is classified as a small signal rectifier diode. This part is Active in product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Alternative part numbers are necessary when original inventory is unavailable, when specific automotive qualifications are required, or when application parameters permit operation at reduced current ratings while maintaining voltage and package compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS40CW_R1_00001 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 40 V minimum
• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount

Allowable Variation Parameters:

• Current - Average Rectified (Io): Equal to or greater than application requirement
• Voltage - Forward (Vf): Lower or equal values acceptable
• Operating Temperature Range: Must encompass application requirements
• Automotive Qualification: Optional enhancement (AEC-Q101)

Substitute parts must maintain identical reverse voltage rating, package form factor, and diode configuration. Current rating may be reduced only if application circuit operates below the original specification. Forward voltage characteristics may improve (lower Vf) without affecting circuit function.

Engineering Selection Recommendations

BAS40CW-AU_R1_000A1 (Panjit International Inc.)

This part is a parametric equivalent to the BAS40CW_R1_00001 with identical electrical specifications and package form factor. The BAS40CW-AU_R1_000A1 carries AEC-Q101 automotive qualification, making it suitable for applications requiring automotive-grade component certification. Both parts share the same base product number (BAS40), forward voltage characteristics, and operating temperature range. Selection of this substitute is appropriate when automotive compliance is mandated or when Panjit inventory of the standard grade is depleted.

RB715FT106 (Rohm Semiconductor)

This part is a similar manufacturer alternative with matching reverse voltage rating, diode configuration, and package form factor. The RB715FT106 operates at a reduced current rating of 30 mA per diode compared to the 200 mA specification of the primary part. This substitute is suitable only for applications where the circuit current requirement does not exceed 30 mA per diode. The RB715FT106 exhibits superior forward voltage characteristics (370 mV @ 1 mA) and is available in higher inventory quantities. The maximum operating temperature is limited to 125°C, which may restrict use in high-temperature applications requiring the full -55°C to 150°C range of the primary part.

Frequently Asked Questions (FAQ)

Q: Can BAS40CW-AU_R1_000A1 be used as a direct replacement for BAS40CW_R1_00001?

A: Yes. Both parts are identical in electrical performance, current rating, voltage rating, and package configuration. The BAS40CW-AU_R1_000A1 includes additional AEC-Q101 automotive qualification. No circuit modifications are required for substitution.

Q: Under what conditions can RB715FT106 replace BAS40CW_R1_00001?

A: The RB715FT106 can replace the BAS40CW_R1_00001 only when the application circuit operates at or below 30 mA per diode. The reverse voltage rating (40 V) and package form factor (SC-70, SOT-323) are identical. Applications requiring the full 200 mA current rating cannot use this substitute. Additionally, if the application requires operation above 125°C junction temperature, the RB715FT106 is not suitable.

Q: Are there package compatibility issues between these parts?

A: All three parts use the SC-70, SOT-323 package form factor and are surface mount devices. Physical footprint and pin configuration are identical. The BAS40CW-AU_R1_000A1 uses SOT-323 supplier device package, while RB715FT106 uses UMD3 supplier device package; however, both are equivalent SC-70, SOT-323 physical packages suitable for the same PCB layout.

Q: What is the significance of the AEC-Q101 qualification on BAS40CW-AU_R1_000A1?

A: AEC-Q101 is an automotive electronics qualification standard. The BAS40CW-AU_R1_000A1 meets this qualification, making it suitable for automotive applications where component certification is required. The standard BAS40CW_R1_00001 does not carry this certification.

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

A: The BAS40CW_R1_00001 and BAS40CW-AU_R1_000A1 both support operation to 150°C junction temperature. The RB715FT106 is limited to 125°C maximum junction temperature. For applications requiring sustained operation above 125°C, only the Panjit parts are suitable.

Q: What are the reverse leakage current differences between these parts?

A: The BAS40CW_R1_00001 specifies 1 µA @ 25 V reverse leakage. The BAS40CW-AU_R1_000A1 specifies 1 µA @ 40 V reverse leakage. The RB715FT106 specifies 1 µA @ 10 V reverse leakage. All three parts meet the same leakage specification at their respective test voltages.
