US5GC-HF Equivalent & Substitute Parts

Part Overview

The US5GC-HF is a general-purpose rectifier diode manufactured by Comchip Technology, rated for 400 V DC reverse voltage and 5 A average rectified current in a surface mount DO-214AB (SMC) package. This component is classified as a fast recovery diode with a reverse recovery time of 50 ns, suitable for standard rectification applications requiring moderate voltage and current ratings.

The US5GC-HF maintains Active product status with 932 pieces currently in stock. Substitute parts are identified for applications requiring equivalent electrical performance, alternative sourcing, or inventory availability considerations. All substitute parts maintain identical or compatible electrical specifications within the allowed parameter ranges for this diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the US5GC-HF are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 5 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 5 A
• Reverse Recovery Time (trr): 50 ns
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

All identified substitute parts meet these core electrical specifications and package requirements. Variations in secondary parameters such as reverse leakage current and capacitance do not preclude substitution when primary electrical ratings and physical form factors remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

US5GC-HF (Comchip Technology): Primary choice for new designs and applications requiring active product status with manufacturer support. ROHS3 compliant with MSL 1 rating. Suitable for standard rectification circuits with 400 V and 5 A specifications.

US5G-TP (Micro Commercial Co): Recommended as the preferred substitute due to Active product status, highest inventory availability (6967 pieces), and identical electrical specifications. ROHS3 compliant with MSL 1 rating. Electrical performance is equivalent to the main part with reverse leakage current of 10 µA at 400 V, which remains within acceptable limits for general-purpose rectification applications.

HS5G V7G (Taiwan Semiconductor Corporation): Qualified as an alternative substitute with equivalent electrical specifications. However, this part is listed as Discontinued at DiGi Electronics, limiting long-term sourcing viability. Reverse leakage current is 10 µA at 400 V. ROHS3 compliant with REACH Unaffected status. Use only when primary and secondary options are unavailable.

All three parts are surface mount devices in DO-214AB (SMC) package format with identical mounting requirements and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: Can US5G-TP be used as a direct replacement for US5GC-HF?

A: Yes. Both parts share identical voltage ratings (400 V), current ratings (5 A), forward voltage drop (1.3 V @ 5 A), reverse recovery time (50 ns), and package format (DO-214AB, SMC). Surface mount assembly compatibility is identical. The reverse leakage current difference (10 µA versus 5 µA at 400 V) does not affect substitution for general-purpose rectification applications.

Q: What is the difference between the three substitute parts?

A: All three parts meet the core electrical specifications for 400 V, 5 A rectification. Primary differences are manufacturer identity, product status, and inventory levels. US5GC-HF and US5G-TP maintain Active status, while HS5G V7G is Discontinued at DiGi Electronics. Reverse leakage current is 5 µA for US5GC-HF and 10 µA for both HS5G V7G and US5G-TP.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All three parts use the DO-214AB (SMC) surface mount package with identical footprint and mounting requirements. PCB layout and assembly processes require no modification when substituting between these parts.

Q: What does the reverse recovery time specification mean for substitution?

A: Reverse recovery time (trr) of 50 ns is identical across all three parts, indicating equivalent switching speed performance. This parameter determines the diode's ability to block reverse current and is critical for fast recovery applications. Identical specifications ensure functional equivalence in switching circuits.

Q: Is RoHS compliance maintained across all substitute parts?

A: Yes. All three parts are ROHS3 compliant, meeting environmental and regulatory requirements for lead-free manufacturing and restricted substance limitations. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.

Q: Why is reverse leakage current higher in the substitute parts?

A: The HS5G V7G and US5G-TP have reverse leakage current of 10 µA at 400 V compared to 5 µA for the US5GC-HF. This difference remains within acceptable limits for general-purpose rectification and does not affect substitution eligibility. Both values are well below typical leakage specifications for this diode category.

Q: Which substitute part should be selected for new production designs?

A: US5G-TP is the recommended choice for new designs due to Active product status, highest inventory availability (6967 pieces), and equivalent electrical performance. This ensures long-term sourcing stability and manufacturer support.
