Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSR01S30SC(TPL3) is determined by strict equivalence across the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 100 mA
• Technology: Schottky
• Mounting Type: Surface Mount
• Package / Case: 0201 (0603 Metric)
• Operating Temperature - Junction: 125°C (Max)

Direct Equivalent: The DSR01S30SL,L3F (Toshiba) is a direct equivalent sharing the same base product number (DSR01S30), electrical ratings, and thermal specifications. This part is active and available in high volume with Tape & Reel packaging.

Similar Substitutes: Parts listed as similar substitutes meet the primary electrical criteria (30 V, 100 mA, Schottky technology, surface mount, 0201 package) but may exhibit variations in forward voltage characteristics, reverse leakage current, or capacitance. These variations remain within acceptable operating ranges for applications designed for the original part specifications.

Parts rated for 200 mA average rectified current (NSR02F30NXT5G, NSR02L30NXT5G, PMEG3002AESFYL) are functionally compatible as they exceed the 100 mA requirement and maintain all other critical parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Recommended for Obsolescence Mitigation):

DSR01S30SL,L3F is the primary recommended substitute. This Toshiba component shares the identical base product number and electrical specifications with the obsolete DSR01S30SC(TPL3). The part is active with high inventory availability (50,001 pcs) and maintains ROHS3 compliance. The only material difference is the package designation change from SC2 to SL2, both representing 0201 (0603 Metric) surface mount configurations. The reverse leakage current improvement (700 nA versus 700 µA) represents enhanced device performance.

Active Alternatives (Multi-Source Strategy):

For applications requiring multiple qualified sources, the following active parts provide full electrical compatibility:

• NSR01L30NXT5G (onsemi): Meets all 100 mA specifications with superior reverse leakage characteristics (3 µA) and extended junction temperature rating (150°C). ROHS3 compliant with high inventory (51,641 pcs).

• SDM02U30LP3-7B (Diodes Incorporated): Provides 100 mA rating with excellent forward voltage performance (370 mV @ 10 mA) and low reverse leakage (4 µA). ROHS3 compliant with substantial inventory (165,300 pcs).

• NSR01F30MXT5G (onsemi): Maintains 100 mA specification with forward voltage of 600 mV @ 100 mA. ROHS3 compliant with high availability (403,990 pcs).

Higher Current Alternatives (Design Margin Applications):

NSR02F30NXT5G, NSR02L30NXT5G, and PMEG3002AESFYL are rated for 200 mA average rectified current. These components are electrically compatible with the 100 mA requirement and provide additional design margin. All are active, ROHS3 compliant, and available in volume.

Compliance Verification:

All recommended substitutes maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. ECCN classification remains EAR99 across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can DSR01S30SL,L3F directly replace DSR01S30SC(TPL3) without circuit modification?

A: Yes. Both parts share the same base product number (DSR01S30), identical electrical ratings (30 V, 100 mA, Schottky technology), and equivalent thermal specifications (125°C junction temperature maximum). The package designation change from SC2 to SL2 represents a supplier device package variation within the same 0201 (0603 Metric) footprint. No circuit modifications are required.

Q: What is the significance of the reverse leakage current difference between the original part (700 µA) and DSR01S30SL,L3F (700 nA)?

A: The DSR01S30SL,L3F exhibits three orders of magnitude lower reverse leakage current (700 nanoamperes versus 700 microamperes). This represents improved device performance and reduced power dissipation in reverse bias conditions. This enhancement is beneficial for circuit operation and does not create compatibility issues.

Q: Are the 200 mA rated parts (NSR02F30NXT5G, NSR02L30NXT5G, PMEG3002AESFYL) suitable substitutes for a 100 mA application?

A: Yes. These parts are electrically compatible as they exceed the 100 mA current requirement while maintaining the 30 V voltage rating and Schottky technology. Higher current rating provides design margin without creating circuit incompatibility. All maintain the 0201 (0603 Metric) package footprint.

Q: What packaging differences exist among the substitute parts?

A: All substitute parts are surface mount components in 0201 (0603 Metric) package dimensions. Supplier device package designations vary (SC2, SL2, 2-X3DFN, 2-DSN, DSN0603-2, X3-DFN0603-2) but represent equivalent physical footprints. PCB layout and reflow soldering parameters remain consistent across all alternatives.

Q: Which substitute offers the best forward voltage performance?

A: SDM02U30LP3-7B provides the lowest forward voltage at 370 mV @ 10 mA. For 100 mA operation, NSR01L30NXT5G offers 530 mV, and PMEG3002AESFYL (200 mA rated) provides 470 mV @ 200 mA. Forward voltage selection depends on specific circuit requirements and thermal dissipation considerations.

Q: Are all substitute parts RoHS compliant?

A: Yes. All recommended substitutes maintain ROHS3 compliance. The original DSR01S30SC(TPL3) is RoHS Compliant. All alternatives are ROHS3 Compliant or equivalent, ensuring regulatory compliance for new designs and production.

Q: What is the operating temperature range difference between the original part and substitutes?

A: The original DSR01S30SC(TPL3) specifies 125°C maximum junction temperature. Most substitutes maintain this specification. NSR01L30MXT5G, NSR01L30NXT5G, PMEG3002AESFYL, and SDM02U30LP3-7B extend the maximum junction temperature to 150°C, providing enhanced thermal margin. This represents an improvement without creating incompatibility.

Q: Can I use NSR01F30NXT5G (Fairchild Semiconductor) as a substitute?

A: Yes. NSR01F30NXT5G meets all primary electrical criteria (30 V, 100 mA, Schottky, 0201 package). The part is active with adequate inventory (79,284 pcs). Forward voltage is 500 mV @ 100 mA with reverse leakage of 50 µA. ECCN classification is EAR99. RoHS status information is not provided in the available data.

Q: What inventory considerations should guide substitute selection?

A: NSR01F30MXT5G (onsemi) offers the highest inventory availability at 403,990 pcs. SDM02U30LP3-7B (Diodes Incorporated) provides 165,300 pcs. NSR02F30NXT5G (onsemi) offers 205,200 pcs. DSR01S30SL,L3F (Toshiba) provides 50,001 pcs. For long-term production continuity, multi-source qualification across manufacturers is recommended.
