Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACGRC303-HF are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V (exact match required)
• Current - Average Rectified (Io): 3 A (exact match required)
• Package / Case: DO-214AB, SMC (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 150°C (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) (Max) @ If: Within acceptable operating range
• Current - Reverse Leakage @ Vr: Acceptable for application
• Moisture Sensitivity Level (MSL): 1 (Unlimited) preferred

Two substitute parts meet these criteria:

1. ES3D-13-F (Diodes Incorporated) — MFR Recommended substitute with faster recovery characteristics
2. S3DH (Taiwan Semiconductor Corporation) — Parametric equivalent with automotive qualification matching the main part

Parameter Comparison

Engineering Selection Recommendations

ACGRC303-HF (Primary Part)

• Active product status with established supply chain
• AEC-Q101 automotive qualification
• ROHS3 compliant
• Standard recovery speed characteristics
• Suitable for general-purpose rectification in automotive and industrial applications

ES3D-13-F (MFR Recommended Substitute)

• Active product status with high inventory availability (45,182 pcs)
• Fast recovery characteristics (≤ 500 ns, trr = 25 ns) provide improved switching performance
• Lower forward voltage drop (900 mV @ 3 A) reduces power dissipation
• ROHS3 compliant with MSL 1 rating
• Available in Cut Tape and Digi-Reel® packaging formats
• No automotive grade or AEC-Q101 qualification specified
• Selection appropriate for non-automotive applications or where fast recovery performance is beneficial

S3DH (Parametric Equivalent Substitute)

• Active product status with moderate inventory (3,680 pcs)
• AEC-Q101 automotive qualification matching main part
• Standard recovery speed characteristics matching main part
• Forward voltage drop identical to main part (1.15 V @ 3 A)
• ROHS3 compliant with MSL 1 rating
• Tape & Reel packaging format matching main part
• Selection appropriate for automotive applications requiring AEC-Q101 qualification

Frequently Asked Questions (FAQ)

Q: Can ES3D-13-F be used as a direct replacement for ACGRC303-HF in automotive applications?

A: ES3D-13-F meets all electrical and mechanical substitution criteria (200 V, 3 A, DO-214AB SMC package, -55 to 150°C operating range, ROHS3 compliance). However, ES3D-13-F does not carry AEC-Q101 automotive qualification. Use in automotive applications requires design validation and qualification review per application requirements.

Q: What is the difference between ES3D-13-F and S3DH?

A: Both parts meet core electrical and mechanical specifications. ES3D-13-F features fast recovery (≤ 500 ns, trr = 25 ns) and lower forward voltage (900 mV @ 3 A), reducing power dissipation in switching applications. S3DH provides standard recovery characteristics (>500 ns, trr = 1.5 µs) and forward voltage matching the main part (1.15 V @ 3 A). S3DH carries AEC-Q101 qualification; ES3D-13-F does not.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the DO-214AB (SMC) surface mount package with identical pinout and footprint. PCB layout and assembly processes require no modification for substitution.

Q: What packaging formats are available?

A: ACGRC303-HF and S3DH are supplied in Tape & Reel (TR) format. ES3D-13-F is available in Cut Tape (CT) and Digi-Reel® formats. Packaging format selection depends on assembly equipment and volume requirements.

Q: Are all parts RoHS compliant?

A: Yes. ACGRC303-HF, ES3D-13-F, and S3DH are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Which substitute should be selected for cost optimization?

A: Selection based on cost requires current pricing and availability data not provided in this reference. Consult supplier quotations for ACGRC303-HF, ES3D-13-F, and S3DH to determine cost-optimized selection for your volume and delivery requirements.
