ES5BC-HF Equivalent & Substitute Parts

Part Overview

The ES5BC-HF is a general-purpose rectifier diode manufactured by Comchip Technology, rated for 100 V DC reverse voltage and 5 A average rectified current in a Surface Mount DO-214AB (SMC) package. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary component experiences supply constraints, inventory depletion, or when design flexibility permits selection from qualified alternatives that meet identical or equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES5BC-HF is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 5 A
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 5 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation Parameters:

• Reverse Recovery Time (trr): Variations within fast recovery classification are acceptable
• Current - Reverse Leakage @ Vr: Minor variations within specification range are acceptable
• Capacitance @ Vr, F: Variations or undocumented values do not disqualify substitution

The following parts meet these substitution criteria:

1. HS5B V7G (Taiwan Semiconductor Corporation) - Parametric equivalent with documented specifications
2. US5B-TP (Micro Commercial Co) - Parametric equivalent with documented specifications

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: ES5BC-HF (Comchip Technology)

The ES5BC-HF maintains Active product status with 820 pieces in stock. This part exhibits superior reverse recovery time performance (35 ns versus 50 ns in alternatives) and lower reverse leakage current (5 µA versus 10 µA), resulting in reduced switching losses and improved thermal efficiency. RoHS3 compliance and MSL 1 rating support long-term supply chain reliability.

Secondary Selection: HS5B V7G (Taiwan Semiconductor Corporation)

The HS5B V7G provides parametric equivalence across all mandatory electrical and mechanical specifications. However, this part is marked as Discontinued at DiGi Electronics, indicating reduced availability through primary distribution channels. Inventory availability is documented at 1632 pieces. This part is suitable for applications where supply of the primary component is constrained and design flexibility permits acceptance of slightly elevated reverse recovery time (50 ns) and reverse leakage current (10 µA).

Tertiary Selection: US5B-TP (Micro Commercial Co)

The US5B-TP is classified as Not For New Designs, indicating manufacturer end-of-life status. This part is supplied in Tape & Reel (TR) packaging, matching the primary component's packaging format. Inventory availability is documented at 19548 pieces. Selection of this part is restricted to legacy design maintenance, repair operations, or applications where existing design validation has been completed and design changes are not permitted. The undocumented capacitance specification does not disqualify this part from substitution eligibility.

Frequently Asked Questions (FAQ)

Q: Can HS5B V7G be used as a direct replacement for ES5BC-HF in new designs?

A: HS5B V7G meets all mandatory electrical and mechanical substitution criteria. However, the part is marked as Discontinued at DiGi Electronics. For new designs, ES5BC-HF is the preferred selection due to Active product status. HS5B V7G is suitable for applications where supply constraints necessitate alternative sourcing.

Q: What is the significance of the 35 ns versus 50 ns reverse recovery time difference?

A: Both parts meet the Fast Recovery classification (≤ 500ns, > 200mA). The ES5BC-HF exhibits faster recovery (35 ns), resulting in lower switching losses and reduced electromagnetic interference. The HS5B V7G and US5B-TP at 50 ns remain within fast recovery specifications and are suitable for standard rectification applications. Selection depends on circuit switching frequency and thermal management requirements.

Q: Are there packaging differences between ES5BC-HF and US5B-TP?

A: Both parts use DO-214AB (SMC) package with Surface Mount mounting type. ES5BC-HF is supplied in Tape & Reel (TR) format. US5B-TP is also supplied in Tape & Reel (TR) format. Packaging format is identical, supporting direct mechanical substitution on automated assembly equipment.

Q: Why is the reverse leakage current specification different between parts?

A: ES5BC-HF specifies 5 µA @ 100 V, while HS5B V7G and US5B-TP specify 10 µA @ 100 V. Both values are within acceptable ranges for general-purpose rectifier applications. Higher leakage current in substitute parts results in marginally increased standby power consumption. This difference is not disqualifying for substitution eligibility.

Q: Can US5B-TP be used in new product designs?

A: US5B-TP is marked as Not For New Designs. This classification indicates manufacturer end-of-life status and reduced long-term availability. Use of this part in new designs is not recommended. This part is restricted to legacy design maintenance and repair operations where design changes are not permitted.

Q: What does RoHS3 compliance indicate?

A: RoHS3 compliance certifies that the component meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. All three parts (ES5BC-HF, HS5B V7G, US5B-TP) are RoHS3 compliant, supporting regulatory compliance in regulated markets.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates Unlimited shelf life without moisture control requirements. All three parts carry MSL 1 rating, eliminating special storage, handling, or baking procedures prior to assembly. This simplifies supply chain management and reduces component preparation costs.

Q: Are there REACH compliance differences between parts?

A: HS5B V7G and US5B-TP are documented as REACH Unaffected. ES5BC-HF does not include REACH status documentation in the provided specifications. For applications requiring explicit REACH compliance verification, HS5B V7G or US5B-TP provide documented compliance status.
