Substitute Part Grouping Explanation

Substitution of the DSF01S30SC,L3F is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 100 mA
• Technology: Schottky
• Mounting Type: Surface Mount
• Operating Temperature - Junction (Max): 125°C

Package Compatibility Considerations:

• Primary equivalent maintains SC2 supplier device package (0201/0603 Metric)
• Secondary substitute uses SL2 supplier device package (2-SMD, No Lead) with different physical footprint

Electrical Performance Tolerance:

• Forward voltage (Vf) variations are acceptable within component specification ranges
• Reverse leakage current variations are acceptable within component specification ranges
• Capacitance variations are acceptable within component specification ranges

Substitutes are grouped based on product status (active vs. obsolete) and packaging format compatibility with the original design.

Engineering Selection Recommendations

Primary Substitute: DSF01S30SC(TPL3)

The DSF01S30SC(TPL3) is the recommended direct replacement for the obsolete DSF01S30SC,L3F. This component maintains identical electrical specifications, package format (SC2), and physical footprint. The part is currently in active production status with 854 units in stock. RoHS compliance is maintained. This substitute requires no design modifications and provides direct pin-for-pin compatibility.

Secondary Substitute: DSR01S30SL,L3F

The DSR01S30SL,L3F is an active Toshiba Schottky diode meeting all critical electrical parameters (30 V, 100 mA, 125°C junction temperature). This component differs in supplier device package format (SL2 vs. SC2) and physical footprint (2-SMD, No Lead vs. 0201/0603 Metric). Forward voltage specification is higher at 620 mV versus 500 mV, and reverse leakage is significantly lower at 700 nA versus 50 µA. This substitute is suitable for applications where package footprint modification is acceptable. Extensive inventory availability (50,001 units) supports high-volume production requirements.

Compliance Considerations:

All substitute components maintain RoHS compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can DSF01S30SC(TPL3) be used as a direct replacement without PCB modification?

A: Yes. The DSF01S30SC(TPL3) maintains identical package format (SC2, 0201/0603 Metric) and electrical specifications to the original DSF01S30SC,L3F. No PCB layout changes are required.

Q: What is the primary difference between DSF01S30SC(TPL3) and DSR01S30SL,L3F?

A: The primary difference is the supplier device package format. DSF01S30SC(TPL3) uses SC2 packaging (0201/0603 Metric), while DSR01S30SL,L3F uses SL2 packaging (2-SMD, No Lead). Additionally, DSR01S30SL,L3F exhibits higher forward voltage (620 mV vs. 500 mV) and significantly lower reverse leakage current (700 nA vs. 50 µA).

Q: Is PCB redesign necessary to use DSR01S30SL,L3F?

A: Yes. The DSR01S30SL,L3F uses a different package footprint (2-SMD, No Lead) compared to the original SC2 package. PCB layout modifications are required for this substitute.

Q: Are all substitute parts RoHS compliant?

A: Yes. Both DSF01S30SC(TPL3) and DSR01S30SL,L3F are RoHS compliant. DSF01S30SC(TPL3) carries RoHS Compliant status, while DSR01S30SL,L3F carries ROHS3 Compliant status.

Q: What is the moisture sensitivity level for these components?

A: All components, including the original and substitutes, are rated MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Which substitute should be selected for new production designs?

A: DSF01S30SC(TPL3) is the recommended choice for new production designs, as it provides direct compatibility with existing PCB layouts and requires no design modifications. DSR01S30SL,L3F is suitable only when package footprint changes are acceptable or required by design constraints.

Q: What are the electrical performance differences between the substitutes?

A: DSF01S30SC(TPL3) maintains identical electrical specifications to the original part. DSR01S30SL,L3F differs in forward voltage (620 mV vs. 500 mV at 100 mA) and reverse leakage current (700 nA vs. 50 µA at 30 V). Both maintain the same 30 V reverse voltage rating and 100 mA current rating.

Q: Are inventory levels sufficient for production requirements?

A: DSF01S30SC(TPL3) has 854 units in stock. DSR01S30SL,L3F has 50,001 units in stock, providing significantly higher availability for high-volume applications.
