VCUT03F1-HD0-G4-08 Equivalent & Substitute Parts

Part Overview

The VCUT03F1-HD0-G4-08 is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. Designed for general-purpose overvoltage protection applications, this surface-mount component operates across a temperature range of -40°C to 125°C and features a 3.3V reverse standoff voltage with 14V maximum clamping voltage at peak pulse current.

The VCUT03F1-HD0-G4-08 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this TVS diode specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VCUT03F1-HD0-G4-08 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Bidirectional Zener TVS diode type with single channel configuration
• Reverse standoff voltage: 3.3V (Max)
• Surface-mount package in 0603 metric footprint
• Operating temperature range: minimum -40°C to 125°C coverage
• RoHS3 compliance and MSL Level 1 rating

Allowable Parameter Variations:

• Voltage - Breakdown (Min): may vary within the 3.3V specification window
• Voltage - Clamping (Max) @ Ipp: acceptable range 13V to 14V
• Current - Peak Pulse (8/20µs): acceptable range 4A to 6A
• Power - Peak Pulse: acceptable range 60W to 78W
• Capacitance @ 1MHz: acceptable range 13pF to 14pF
• Operating temperature upper limit: may extend to 150°C

The substitute part VCUT03E1-SD0-G4-08 meets all mandatory compatibility criteria and operates within the allowable parameter variation ranges.

Parameter Comparison

Engineering Selection Recommendations

The VCUT03E1-SD0-G4-08 is the manufacturer-recommended substitute for the obsolete VCUT03F1-HD0-G4-08. Both components share identical reverse standoff voltage specifications, package footprints, and compliance certifications (ROHS3, MSL Level 1).

The substitute part offers enhanced performance characteristics: increased peak pulse current rating (6A versus 4A), higher peak pulse power dissipation (78W versus 60W), and an extended operating temperature range (-55°C to 150°C versus -40°C to 125°C). The clamping voltage is marginally lower (13V versus 14V), which provides improved transient suppression performance.

Product status consideration: VCUT03E1-SD0-G4-08 is classified as Last Time Buy, indicating limited future availability. Long-term design strategies should evaluate the secondary substitute options referenced in the substitute part's documentation.

Frequently Asked Questions (FAQ)

Q: Can VCUT03E1-SD0-G4-08 be used as a direct replacement for VCUT03F1-HD0-G4-08?

A: Yes. Both components are single-channel bidirectional Zener TVS diodes with identical 3.3V reverse standoff voltage, 0603 metric package footprint, and surface-mount configuration. Electrical performance parameters fall within compatible ranges for general-purpose overvoltage protection applications.

Q: What are the key differences between these two parts?

A: The substitute part features higher peak pulse current (6A versus 4A), greater peak pulse power dissipation (78W versus 60W), lower clamping voltage (13V versus 14V), and an extended operating temperature range (-55°C to 150°C versus -40°C to 125°C). These differences represent performance enhancements rather than incompatibilities.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 0603 metric (0201 imperial) surface-mount package. The main part uses LLP0603-2L packaging while the substitute uses CLP0603 packaging; both are mechanically and electrically compatible with standard 0603 footprints.

Q: What is the significance of the product status change from Obsolete to Last Time Buy?

A: The main part (VCUT03F1-HD0-G4-08) is obsolete and no longer manufactured. The substitute part (VCUT03E1-SD0-G4-08) is in Last Time Buy status, meaning production will cease at a defined future date. Designs should plan accordingly for long-term component sourcing.

Q: Are both parts RoHS3 compliant?

A: Yes. Both VCUT03F1-HD0-G4-08 and VCUT03E1-SD0-G4-08 are ROHS3 compliant with MSL Level 1 (unlimited moisture sensitivity rating), meeting current environmental and regulatory requirements.

Q: Can the substitute part handle higher transient currents?

A: Yes. VCUT03E1-SD0-G4-08 is rated for 6A peak pulse current (8/20µs) compared to 4A for the main part, providing additional margin for transient suppression in higher-energy surge environments.
