Substitute Part Grouping Explanation

Substitute parts for the S1FLD-GS18 are qualified based on electrical parameter equivalence and mechanical compatibility. The substitution criteria are defined by the following parameters:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 700 mA
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Reverse Recovery Time (trr): 1.8 µs
• Current - Reverse Leakage @ Vr: 10 µA @ 200 V
• Capacitance @ Vr, F: 4 pF @ 4V, 1MHz
• Operating Temperature - Junction: -55°C to 150°C
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical requirements. Differences in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and automotive qualification do not affect electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—S1FLD-GS18, S07D-GS08, and S1FLD-GS08—are electrically and mechanically equivalent for general-purpose rectifier applications requiring 200 V, 700 mA surface mount diodes in DO-219AB packaging.

S1FLD-GS18 is the primary part number with Tape & Reel packaging and standard product status.

S07D-GS08 is an equivalent substitute with identical electrical specifications and Tape & Reel packaging. This part carries AEC-Q101 automotive qualification, making it suitable for applications requiring automotive-grade components. Selection of this part is appropriate when automotive compliance is mandated by application requirements.

S1FLD-GS08 is an equivalent substitute with identical electrical specifications but supplied in Cut Tape & Digi-Reel format. This packaging option is suitable for applications where smaller order quantities or alternative tape formats are preferred. The electrical performance is identical to the primary part.

All parts are RoHS3 compliant, carry unlimited moisture sensitivity level (MSL 1), and operate across the same temperature range (-55°C to 150°C junction temperature).

Frequently Asked Questions (FAQ)

Q: Can S07D-GS08 be used as a direct replacement for S1FLD-GS18?

A: Yes. S07D-GS08 is electrically and mechanically equivalent to S1FLD-GS18. Both parts share identical voltage ratings (200 V), current ratings (700 mA), forward voltage characteristics (1.1 V @ 1 A), reverse recovery time (1.8 µs), and package specifications (DO-219AB surface mount). The primary difference is that S07D-GS08 includes AEC-Q101 automotive qualification. Packaging format differs (both are Tape & Reel), but this does not affect electrical interchangeability.

Q: What is the difference between S1FLD-GS08 and S1FLD-GS18?

A: S1FLD-GS08 and S1FLD-GS18 are electrically identical. Both are rated for 200 V, 700 mA, and use the DO-219AB package. The difference is in packaging format: S1FLD-GS18 is supplied in Tape & Reel (TR) format, while S1FLD-GS08 is supplied in Cut Tape (CT) & Digi-Reel format. Selection between these parts depends on order quantity requirements and supply chain preferences.

Q: Does the automotive qualification of S07D-GS08 affect its use in non-automotive applications?

A: No. AEC-Q101 qualification indicates that S07D-GS08 meets automotive industry standards and testing requirements. This qualification does not restrict use in non-automotive applications. S07D-GS08 is suitable for any application requiring a 200 V, 700 mA general-purpose rectifier diode in DO-219AB packaging.

Q: Are all three parts RoHS3 compliant?

A: Yes. S1FLD-GS18, S07D-GS08, and S1FLD-GS08 are all RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: What is the operating temperature range for these diodes?

A: All three parts operate across a junction temperature range of -55°C to 150°C.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the packaging format is compatible with the assembly process. S1FLD-GS18 and S07D-GS08 use standard Tape & Reel packaging. S1FLD-GS08 uses Cut Tape & Digi-Reel packaging. All three parts use the same DO-219AB surface mount package, so they are mechanically compatible with the same PCB footprint and reflow soldering process.
