VCUT05F1-HD0-G4-08 Equivalent & Substitute Parts

Part Overview

The VCUT05F1-HD0-G4-08 is a transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This bidirectional Zener TVS diode is designed for general-purpose overvoltage protection in surface-mount applications. With a 5.5V reverse standoff voltage and 14V maximum clamping voltage, it provides transient suppression for sensitive electronic circuits.

The VCUT05F1-HD0-G4-08 is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VCUT05F1-HD0-G4-08 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Reverse standoff voltage: 5.5V (Max)
• Bidirectional channel configuration: 1 channel
• Zener diode type classification
• Surface-mount package format: 0603 Metric equivalent
• General-purpose application category

Mechanical Compatibility Criteria:

• Surface-mount mounting type
• 0603 Metric package footprint compatibility

The substitute part VCUT05E1-SD0-G4-08 meets these core substitution criteria. While it exhibits different clamping voltage (11V vs. 14V), peak pulse current (6A vs. 4A), and power dissipation (78W vs. 60W) characteristics, it maintains the same reverse standoff voltage, bidirectional Zener configuration, and surface-mount package compatibility required for functional equivalence in general-purpose TVS applications.

Engineering Selection Recommendations

The VCUT05E1-SD0-G4-08 is the manufacturer-recommended substitute for the obsolete VCUT05F1-HD0-G4-08. Both components are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory compliance.

The substitute part offers an extended operating temperature range (-55°C to 150°C versus -40°C to 125°C), enhanced peak pulse current handling (6A versus 4A), and increased power dissipation capability (78W versus 60W). The substitute maintains the same reverse standoff voltage (5.5V Max) and bidirectional Zener configuration, preserving core circuit protection functionality.

The VCUT05E1-SD0-G4-08 is available in Tape & Reel packaging with significantly higher inventory levels (35,300 pieces) compared to the obsolete main part, supporting production continuity and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the VCUT05E1-SD0-G4-08 directly replace the VCUT05F1-HD0-G4-08 in existing designs?

A: Yes. Both components share identical reverse standoff voltage (5.5V Max), bidirectional Zener configuration, and 0603 Metric surface-mount package format. The substitute meets the core electrical and mechanical substitution criteria for general-purpose TVS applications.

Q: What are the differences in electrical performance between these parts?

A: The substitute exhibits lower clamping voltage (11V Typ versus 14V Max), higher peak pulse current capability (6A versus 4A), and greater power dissipation (78W versus 60W). The substitute also features an extended operating temperature range (-55°C to 150°C versus -40°C to 125°C).

Q: Are both parts compatible with the same PCB footprint?

A: Yes. Both components use the 0603 Metric surface-mount package format and are compatible with identical PCB layouts and reflow soldering processes.

Q: What is the significance of the product status difference?

A: The main part (VCUT05F1-HD0-G4-08) is classified as obsolete, indicating end-of-life status and unavailability for new orders. The substitute (VCUT05E1-SD0-G4-08) is classified as Last Time Buy, indicating limited availability with a defined end-of-support date. The substitute provides a transition path for designs requiring TVS diode protection in the 5.5V standoff voltage category.

Q: Do both parts meet the same regulatory and environmental standards?

A: Yes. Both components are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent compliance with environmental and regulatory requirements.
