BAS69-04WFILM Equivalent & Substitute Parts

Part Overview

The BAS69-04WFILM is a Schottky diode array manufactured by STMicroelectronics, configured as 1 pair series connection with a maximum reverse voltage rating of 15 V and average rectified current of 10 mA per diode. The device is housed in a surface mount SC-70, SOT-323 package and is classified as obsolete product status.

Due to the obsolete status of the BAS69-04WFILM, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. Substitute parts must maintain electrical and mechanical compatibility within the allowed parameter ranges for this diode array category.

Parameter Comparison

Engineering Selection Recommendations

1PS70SB84,115 (Nexperia USA Inc.)

The 1PS70SB84,115 is an active product that maintains the same reverse voltage rating (15 V) and package configuration as the BAS69-04WFILM. This part provides a 3× increase in average rectified current capacity (30 mA versus 10 mA), making it suitable for applications requiring higher current handling. The part carries AEC-Q100 automotive qualification and ROHS3 compliance. The maximum junction temperature is rated at 125°C, which is 25°C lower than the BAS69-04WFILM specification.

BAT54SW,115 (Nexperia USA Inc.)

The BAT54SW,115 is an active product offering enhanced electrical specifications with a 30 V reverse voltage rating and 200 mA average rectified current capacity. This part is suitable for applications requiring higher voltage and current margins. The BAT54SW,115 maintains the same SC-70, SOT-323 package and surface mount configuration. The part carries AEC-Q101 automotive qualification and ROHS3 compliance. The maximum junction temperature is rated at 150°C, matching the BAS69-04WFILM specification.

Both substitute parts are available in high inventory quantities and are classified as active products, ensuring long-term supply chain availability compared to the obsolete BAS69-04WFILM.

Frequently Asked Questions (FAQ)

Q: Can the 1PS70SB84,115 be used as a direct replacement for the BAS69-04WFILM?

A: The 1PS70SB84,115 is electrically compatible with the BAS69-04WFILM in applications where the 10 mA current requirement does not exceed the design margin. Both parts share identical reverse voltage ratings (15 V), diode configuration (1 Pair Series Connection), and package type (SC-70, SOT-323). However, the 1PS70SB84,115 has a maximum junction temperature of 125°C compared to 150°C for the BAS69-04WFILM. Circuit thermal analysis is required to confirm suitability in high-temperature environments.

Q: What are the key differences between the 1PS70SB84,115 and BAT54SW,115?

A: The primary differences are reverse voltage rating and current capacity. The 1PS70SB84,115 maintains the 15 V reverse voltage of the BAS69-04WFILM with 30 mA current capacity, while the BAT54SW,115 provides 30 V reverse voltage and 200 mA current capacity. Both parts use identical SC-70, SOT-323 packaging. The BAT54SW,115 offers greater design margin for voltage and current specifications but may introduce unnecessary cost in applications with lower requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. The BAS69-04WFILM, 1PS70SB84,115, and BAT54SW,115 are all ROHS3 compliant. All parts carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: Do the substitute parts have automotive qualifications?

A: The 1PS70SB84,115 carries AEC-Q100 qualification. The BAT54SW,115 carries AEC-Q101 qualification. The BAS69-04WFILM does not list automotive qualification in the provided specifications. Automotive applications should select parts with appropriate AEC-Q qualification levels.

Q: Can the BAT54SW,115 be used in all applications where the BAS69-04WFILM was used?

A: The BAT54SW,115 is electrically compatible with the BAS69-04WFILM in all applications. The higher voltage rating (30 V versus 15 V) and current capacity (200 mA versus 10 mA) provide design margin. Both parts share identical package and mounting characteristics (SC-70, SOT-323, surface mount). The BAT54SW,115 is suitable for direct substitution in existing designs.

Q: What is the significance of the SOT-323 package designation?

A: SOT-323 is a surface mount package standard that defines the physical dimensions, pin configuration, and soldering interface. All three parts (BAS69-04WFILM, 1PS70SB84,115, and BAT54SW,115) use the SC-70, SOT-323 package, ensuring mechanical and electrical compatibility on printed circuit boards without layout modifications.
