BAS69WFILM Equivalent & Substitute Parts

Part Overview

The BAS69WFILM is a Schottky diode manufactured by STMicroelectronics, rated for 15 V DC reverse voltage with a 10 mA average rectified current. The device is packaged in a surface mount SC-70/SOT-323 configuration and is designed for small signal applications. The BAS69WFILM is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility while offering active product status and continued supplier availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS69WFILM is determined by the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 15 V
• Current - Average Rectified (Io): Must equal or exceed 10 mA
• Technology: Schottky diode type
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed

Mechanical Compatibility Criteria:

• Package / Case: SC-70 or SOT-323
• Mounting Type: Surface Mount

Compliance Requirements:

• RoHS3 Compliant status
• REACH Unaffected status

The substitute part 1PS70SB82,115 meets all electrical and mechanical compatibility requirements. This part maintains the same reverse voltage rating (15 V), exceeds the minimum current requirement (30 mA vs. 10 mA), utilizes identical packaging (SOT-323), and maintains equivalent Schottky technology classification. The substitute part is active in production status with automotive-grade qualification (AEC-Q100).

Engineering Selection Recommendations

The 1PS70SB82,115 manufactured by Nexperia USA Inc. is a direct functional substitute for the obsolete BAS69WFILM. Selection of this substitute part is based on the following engineering factors:

Product Status: The BAS69WFILM is obsolete, while the 1PS70SB82,115 maintains active production status with established supplier availability.

Electrical Compatibility: The substitute part maintains identical reverse voltage rating (15 V) and exceeds the current requirement (30 mA vs. 10 mA), ensuring operation within all specified electrical parameters for applications designed around the original part.

Packaging and Mounting: Both parts utilize identical SC-70/SOT-323 surface mount packaging, enabling direct board-level substitution without layout modifications.

Compliance and Certifications: The substitute part maintains ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original component. The substitute part carries AEC-Q100 automotive qualification, providing additional quality assurance for applications requiring automotive-grade components.

Temperature Considerations: The substitute part specifies a maximum junction temperature of 125°C compared to the original part's 150°C rating. Applications operating near the upper thermal limits of the original design require thermal analysis to confirm compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1PS70SB82,115 be used as a direct replacement for the BAS69WFILM in existing designs?

A: Yes. Both parts share identical reverse voltage ratings (15 V), equivalent Schottky technology, and identical SOT-323 packaging. The substitute part's higher current rating (30 mA vs. 10 mA) does not create incompatibility in applications designed for the original 10 mA specification.

Q: What is the primary reason for substitution?

A: The BAS69WFILM is classified as obsolete. The 1PS70SB82,115 is an active product with established supplier availability, ensuring long-term component sourcing for production and design continuity.

Q: Are there packaging differences between these parts?

A: No. Both parts are supplied in SC-70/SOT-323 surface mount packages. The 1PS70SB82,115 is supplied in Tape & Reel (TR) packaging format, which is standard for high-volume production applications.

Q: How do the forward voltage characteristics compare?

A: The BAS69WFILM specifies 570 mV maximum forward voltage at 10 mA, while the 1PS70SB82,115 specifies 700 mV maximum at 30 mA. These measurements are taken at different current levels. Circuit designs must account for the forward voltage characteristics at the actual operating current of the application.

Q: What is the significance of the AEC-Q100 qualification on the substitute part?

A: AEC-Q100 qualification indicates the substitute part meets automotive industry reliability and quality standards. This certification is relevant for applications requiring automotive-grade components but does not affect compatibility for general-purpose applications.

Q: Are there thermal considerations when substituting these parts?

A: The substitute part specifies a maximum junction temperature of 125°C compared to the original part's 150°C. Applications operating at elevated temperatures near the original part's thermal limits require thermal analysis to confirm the substitute part remains within acceptable operating conditions.

Q: Do both parts have identical reverse leakage characteristics?

A: The BAS69WFILM specifies 230 nA reverse leakage at 15 V, while the 1PS70SB82,115 specifies 200 nA at 1 V. These measurements are taken at different voltage levels. The substitute part demonstrates lower leakage at the lower measurement voltage.
