BAS70L-QYL Equivalent & Substitute Parts

Part Overview

The BAS70L-QYL is an automotive-grade Schottky diode manufactured by Nexperia USA Inc., designed for surface mount applications in the SOD-882 package. This component operates at 70V reverse voltage with 70mA average rectified current and is qualified to AEC-Q101 automotive standards. The part is currently in active production status with 9594 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required for design flexibility, supply chain continuity, or manufacturing process optimization.

Substitute Part Grouping Explanation

Substitution of the BAS70L-QYL is determined by matching the following critical electrical and mechanical parameters:

Voltage - DC Reverse (Vr) (Max): 70 V
Current - Average Rectified (Io): 70 mA
Voltage - Forward (Vf) (Max) @ If: 1 V @ 15 mA
Current - Reverse Leakage @ Vr: 10 µA @ 70 V
Capacitance @ Vr, F: 2 pF @ 0V, 1MHz
Operating Temperature - Junction: 150°C
Package / Case: SOD-882
Mounting Type: Surface Mount
Technology: Schottky
RoHS Status: ROHS3 Compliant

All identified substitute parts maintain these core electrical specifications and physical package requirements. Variations in supplier device package designation (DFN1006-2 versus DFN1006BD-2), automotive qualification level (AEC-Q101 versus AEC-Q100), and moisture sensitivity level (MSL 1 versus MSL 3) are noted but do not prevent functional substitution when application requirements permit.

Engineering Selection Recommendations

All three parts—BAS70L-QYL, BAS70LS-QYL, and BAS70LSYL—are manufactured by Nexperia USA Inc. and share identical electrical performance specifications for the 70V/70mA Schottky diode function. Selection between these parts is based on the following criteria:

BAS70L-QYL is the primary reference part with AEC-Q101 automotive qualification and MSL 1 moisture sensitivity rating, suitable for applications requiring the highest automotive qualification level and unlimited shelf life under controlled storage.

BAS70LS-QYL provides equivalent electrical performance with AEC-Q100 automotive qualification and MSL 3 moisture sensitivity rating. This part is appropriate for applications where AEC-Q100 qualification is acceptable and moisture control during storage and handling is implemented.

BAS70LSYL offers equivalent electrical performance with MSL 1 moisture sensitivity rating but lacks specified automotive qualification documentation. This part is suitable for non-automotive applications or where automotive qualification is not a design requirement.

All parts are ROHS3 compliant, REACH unaffected, and available in active production status. Selection should be based on specific automotive qualification requirements and moisture sensitivity constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can BAS70LS-QYL be used as a direct replacement for BAS70L-QYL?

A: BAS70LS-QYL provides identical electrical performance and operates in the same SOD-882 surface mount package. The primary differences are AEC-Q100 versus AEC-Q101 automotive qualification and MSL 3 versus MSL 1 moisture sensitivity. Direct substitution is permissible when the application does not require AEC-Q101 qualification and moisture control procedures are in place.

Q: What is the difference between DFN1006-2 and DFN1006BD-2 supplier device packages?

A: Both designations refer to the same physical SOD-882 package footprint and are mechanically compatible. The "BD" designation in DFN1006BD-2 indicates a specific manufacturing variant. No design changes are required when substituting between these package designations.

Q: Is BAS70LSYL suitable for automotive applications?

A: BAS70LSYL meets the electrical specifications and RoHS3 compliance requirements but does not carry specified automotive qualification documentation. Use in automotive applications should be evaluated against specific design qualification requirements.

Q: What does MSL 1 (Unlimited) versus MSL 3 (168 Hours) mean for component handling?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and can be stored indefinitely under controlled conditions. MSL 3 (168 Hours) requires that the component be used within 168 hours of package opening under specified humidity conditions. Selection depends on manufacturing process capabilities and inventory management practices.

Q: Are all three parts available in the same packaging format?

A: All three parts are supplied in Tape & Reel (TR) packaging format suitable for automated assembly processes. Inventory levels vary: BAS70L-QYL (9594 pcs), BAS70LS-QYL (9484 pcs), and BAS70LSYL (5530 pcs).
