Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S1DFS MWG is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 1 µA @ 200 V
• Capacitance @ Vr, F: 9 pF @ 4V, 1MHz

Mechanical Parameters (Must Match):

• Package / Case: SOD-128
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into two categories based on packaging format and automotive qualification:

Category 1 - Standard Industrial Grade (Tape & Reel): S1DFS and S1DFSH maintain identical electrical specifications with Tape & Reel packaging format.

Category 2 - Automotive Grade (Cut Tape): S1DFSHMWG provides automotive-grade qualification (AEC-Q101) with Cut Tape packaging format, suitable for applications requiring automotive component certification.

Parameter Comparison

Engineering Selection Recommendations

The Cut Tape packaging format is suitable for lower-volume production runs or applications requiring individual component handling.

For Inventory and Supply Chain Optimization: S1DFS offers the highest inventory availability at 28,933 units in Tape & Reel format, suitable for high-volume manufacturing operations. S1DFSH provides comparable availability at 29,128 units with automotive qualification. S1DFSHMWG is available in limited quantity (1,188 units) in Cut Tape format for specialized applications.

All substitute parts maintain Active product status and full ROHS3 compliance, ensuring long-term component availability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can S1DFS be used as a direct replacement for S1DFS MWG?

A: Yes. S1DFS is a parametric equivalent with identical electrical specifications (200 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage, standard recovery speed, and matching leakage and capacitance characteristics). Both parts are housed in SOD-128 surface mount packages with identical operating temperature ranges (-55°C to 150°C) and ROHS3 compliance. The primary difference is packaging format: S1DFS MWG is supplied in Tape & Reel format, while S1DFS is also supplied in Tape & Reel format with higher inventory availability.

Q: What is the difference between S1DFSH and S1DFSHMWG?

A: Both S1DFSH and S1DFSHMWG are automotive-grade variants with AEC-Q101 qualification and identical electrical specifications to the standard industrial parts. The primary difference is packaging format: S1DFSH is supplied in Tape & Reel (TR) format, while S1DFSHMWG is supplied in Cut Tape (CT) format. Cut Tape packaging is typically used for lower-volume applications or manual assembly processes, while Tape & Reel is standard for automated high-volume production.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts (S1DFS, S1DFSH, and S1DFSHMWG) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the S1DFS MWG.

Q: Which substitute part should be selected for automotive applications?

A: S1DFSH or S1DFSHMWG should be selected for automotive applications. Both parts carry AEC-Q101 automotive qualification. S1DFSH is available in Tape & Reel format (29,128 units in stock) for high-volume automotive production. S1DFSHMWG is available in Cut Tape format (1,188 units in stock) for lower-volume or specialized automotive applications.

Q: Do all substitute parts operate within the same temperature range?

A: Yes. All substitute parts operate within the identical junction temperature range of -55°C to 150°C, ensuring thermal compatibility across all applications.

Q: Can packaging format be changed during production?

A: Packaging format selection (Tape & Reel versus Cut Tape) is determined at the time of component procurement and cannot be changed during production. Tape & Reel format is standard for automated assembly lines, while Cut Tape format is used for manual assembly or lower-volume production runs. Component selection must account for manufacturing process requirements.

Q: Are there any electrical performance differences between the substitute parts?

A: No. All substitute parts maintain identical electrical specifications: 200 V reverse voltage rating, 1 A average rectified current, 1.1 V maximum forward voltage at 1 A, standard recovery speed (>500 ns at >200 mA), 1 µA reverse leakage current at 200 V, and 9 pF capacitance at 4 V and 1 MHz. Electrical performance is equivalent across all variants.
