Substitute Part Grouping Explanation

Substitution for BAS40LS-QYL is determined by matching key electrical and mechanical parameters including technology type (Schottky), maximum DC reverse voltage, average rectified current, forward voltage characteristics, reverse leakage at specified voltage, capacitance, mounting type, and package form factor. Compliance with automotive standards and environmental directives is also critical for interchangeability in automotive and regulated applications.

Key parameters used for substitution:

• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 120mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 40 mA
• Current - Reverse Leakage @ Vr: 10 µA @ 40 V
• Capacitance @ Vr, F: 5pF @ 0V, 1MHz
• Mounting Type: Surface Mount (DFN1006BD-2 / SOD-882)
• Automotive Grade and Qualification (for automotive applications)
• RoHS3 compliance and corresponding moisture sensitivity levels

Parameter Comparison

Engineering Selection Recommendations

Both BAS40LS-QYL and BAS40LSYL meet active product status criteria, are AEC-Q100 qualified for automotive applications and are ROHS3 compliant. The primary difference is the moisture sensitivity level (MSL), where BAS40LSYL offers unlimited shelf life (MSL 1) compared to BAS40LS-QYL (MSL 3, 168 hours). Selection between these equivalents can be based on internal supply procedures and handling requirements in relation to moisture sensitivity levels. All other parameters and regulatory compliance requirements are identical.

Frequently Asked Questions (FAQ)

Q1: What establishes electrical equivalence between BAS40LS-QYL and BAS40LSYL?
A1: Both models share identical Schottky technology, voltage and current ratings, forward voltage drop, reverse leakage, and capacitance, as well as surface-mount DFN1006BD-2 (SOD-882) packaging.

Q2: Is automotive qualification maintained in all substitute choices?
A2: Yes. Both BAS40LS-QYL and BAS40LSYL are AEC-Q100 qualified, meeting automotive grade standards.

Q3: Are there any differences in environmental compliance or handling between the parts?
A3: Both parts are ROHS3 compliant. The main difference is MSL: BAS40LS-QYL is rated at MSL 3 (168 Hours) while BAS40LSYL is MSL 1 (Unlimited).

Q4: Are substitute parts compatible in PCB layout and assembly processes?
A4: Both models use the same surface-mount DFN1006BD-2 (SOD-882) package and are pin-compatible.

Q5: What should be checked for moisture sensitivity in component handling?
A5: Moisture sensitivity level varies: BAS40LS-QYL is MSL 3 and BAS40LSYL is MSL 1. Selection should reflect production storage duration and reflow requirements.
