ES3AC-HF Equivalent & Substitute Parts

Part Overview

The ES3AC-HF is a general-purpose rectifier diode manufactured by Comchip Technology, rated for 50 V DC reverse voltage and 3 A average rectified current in a DO-214AB surface mount package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when the primary ES3AC-HF component experiences supply discontinuation, extended lead times, or inventory constraints. The parts listed below provide electrical and mechanical equivalence within the specified parameter tolerances for this diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES3AC-HF is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 3 A
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Standard
• RoHS Status: ROHS3 Compliant

Secondary Parameters (Allowable Variation):

• Reverse Recovery Time (trr): Variation permitted within fast recovery classification
• Current - Reverse Leakage @ Vr: Variation permitted within specified voltage rating
• Capacitance @ Vr, F: Variation permitted for non-critical applications
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) formats are interchangeable for component selection

The substitute parts identified below satisfy all mandatory equivalence criteria and are therefore direct functional replacements for the ES3AC-HF in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

ES3AC-HF (Primary Selection): The ES3AC-HF maintains Active product status with current availability of 795 pieces in stock. This component is the preferred selection for new designs and ongoing production due to sustained manufacturer support and supply continuity.

HS3A R7G (Substitute - Cut Tape Packaging): The HS3A R7G provides full parametric equivalence with 1451 pieces available in inventory. This part is discontinued at DiGi Electronics but remains functionally compatible. The Cut Tape packaging format is suitable for automated assembly processes. Secondary parameter variations (reverse recovery time of 50 ns versus 35 ns, reverse leakage of 10 µA versus 5 µA, and capacitance of 80 pF versus 40 pF) remain within acceptable tolerances for standard rectifier applications.

HS3A V7G (Substitute - Unspecified Packaging): The HS3A V7G provides full parametric equivalence with 2561 pieces available in inventory. This part is discontinued at DiGi Electronics. Packaging format is not specified in the provided data. Secondary parameter variations are identical to HS3A R7G. Packaging confirmation is required prior to procurement for assembly compatibility verification.

Both substitute parts carry ROHS3 compliance and unlimited moisture sensitivity rating, matching the primary component's environmental certifications.

Frequently Asked Questions (FAQ)

Q: Can HS3A R7G and HS3A V7G be used interchangeably with ES3AC-HF?

A: Yes. Both substitute parts meet all mandatory equivalence criteria: 50 V reverse voltage rating, 3 A average rectified current, 1 V forward voltage at 3 A, DO-214AB surface mount package, and -55°C to 150°C operating temperature range. Secondary parameter variations in reverse recovery time, reverse leakage current, and capacitance do not affect functional compatibility in standard rectifier circuit applications.

Q: What is the difference between HS3A R7G and HS3A V7G?

A: Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical specifications. The primary difference is packaging format: HS3A R7G is supplied in Cut Tape (CT) format, while HS3A V7G packaging format is not specified. Inventory availability differs, with HS3A V7G offering 2561 pieces versus 1451 pieces for HS3A R7G.

Q: Why does HS3A R7G have higher reverse leakage current (10 µA) compared to ES3AC-HF (5 µA)?

A: Reverse leakage current variation within the specified voltage rating is a normal characteristic difference between manufacturers and production lots. Both values remain within acceptable limits for general-purpose rectifier applications. Circuit designs should account for maximum specified leakage current rather than typical values.

Q: Are there packaging compatibility concerns when substituting ES3AC-HF with HS3A R7G?

A: No. Both components use identical DO-214AB surface mount packages. HS3A R7G is supplied in Cut Tape format while ES3AC-HF is supplied in Tape & Reel format. Both formats are compatible with standard surface mount assembly equipment and processes.

Q: What is the significance of the "Discontinued at DiGi Electronics" status for substitute parts?

A: This status indicates that the manufacturer has discontinued the part at this specific distributor. However, inventory remains available through current stock. Discontinued status does not affect functional performance or compliance certifications. Long-term availability should be confirmed with the manufacturer or alternative distributors prior to committing to high-volume production.

Q: Do all three parts meet RoHS3 compliance requirements?

A: Yes. ES3AC-HF, HS3A R7G, and HS3A V7G all carry ROHS3 Compliant certification. All three parts are suitable for applications requiring RoHS3 compliance.
