Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFM18PL-TP are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 1 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Surface Mount
• Package / Case: SOD-123F or SOD-123FL

Allowable Variation Parameters:

• Reverse Recovery Time (trr): Within fast recovery classification
• Current - Reverse Leakage @ Vr: Variation acceptable within specification
• Capacitance @ Vr, F: Variation acceptable
• Operating Temperature - Junction: Equal or extended range acceptable
• RoHS and MSL compliance: Equal or higher compliance level acceptable

Substitute parts ES1006FL_R1_00001 and USL1J meet these criteria and are classified as equivalent alternatives.

Parameter Comparison

Engineering Selection Recommendations

SFM18PL-TP (Primary Part): Active product status with 2,900 units in stock. RoHS3 compliant and MSL Level 1 (Unlimited). Suitable for applications requiring standard fast recovery rectification at 600 V, 1 A ratings.

ES1006FL_R1_00001 (Substitute - Panjit International Inc.): Active product status with 20,400 units in stock. RoHS3 compliant and MSL Level 1 (Unlimited). Extended operating temperature range (-55°C to 150°C) compared to primary part. Lower reverse leakage current (500 nA vs. 5 µA) and lower capacitance (7 pF vs. 10 pF). Identical reverse recovery time (35 ns). Direct electrical and mechanical equivalent.

USL1J (Substitute - Diotec Semiconductor): Active product status with 4,013 units in stock. RoHS3 compliant. MSL classification not applicable. Reverse recovery time of 75 ns exceeds primary part specification (35 ns) but remains within fast recovery classification. Lower reverse leakage current (1 µA). Package designation SOD-123F (SMF) is mechanically compatible. Suitable for applications where extended reverse recovery time is acceptable.

All three parts are RoHS3 compliant and suitable for direct substitution based on electrical performance and mechanical compatibility within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can ES1006FL_R1_00001 be used as a direct replacement for SFM18PL-TP?

A: Yes. Both parts share identical electrical ratings (600 V, 1 A, 1.7 V forward voltage, 35 ns reverse recovery time) and are packaged in SOD-123F surface mount format. ES1006FL_R1_00001 offers extended operating temperature range (-55°C to 150°C vs. -50°C to 150°C) and lower reverse leakage current, making it a compatible substitute.

Q: What is the difference between SFM18PL-TP and USL1J?

A: Both parts are rated 600 V, 1 A with 1.7 V forward voltage and are surface mount SOD-123F packaged. The primary difference is reverse recovery time: SFM18PL-TP specifies 35 ns while USL1J specifies 75 ns. Both remain within the fast recovery classification (≤ 500ns, > 200mA). USL1J is suitable for applications where the extended recovery time does not impact circuit performance.

Q: Are all three parts RoHS3 compliant?

A: Yes. SFM18PL-TP, ES1006FL_R1_00001, and USL1J are all RoHS3 compliant.

Q: What is the package compatibility between these parts?

A: SFM18PL-TP and ES1006FL_R1_00001 use SOD-123FL packaging. USL1J uses SOD-123F (SMF) packaging. Both SOD-123F and SOD-123FL are mechanically compatible surface mount packages suitable for identical PCB footprints.

Q: Which substitute part has the lowest reverse leakage current?

A: ES1006FL_R1_00001 has the lowest reverse leakage current at 500 nA @ 600 V, compared to 1 µA for USL1J and 5 µA for SFM18PL-TP.

Q: Can USL1J be used in high-frequency switching applications?

A: USL1J has a reverse recovery time of 75 ns, which is longer than SFM18PL-TP (35 ns) and ES1006FL_R1_00001 (35 ns). Application suitability depends on circuit switching frequency requirements. Both 35 ns and 75 ns specifications fall within the fast recovery classification.

Q: What is the moisture sensitivity level difference between these parts?

A: SFM18PL-TP and ES1006FL_R1_00001 are both MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions. USL1J has MSL classification listed as Not Applicable, indicating no moisture sensitivity concern for this component type.
