Key Parameters

Substitute Part Grouping Explanation

Substitution of the VBUS54GD-FBL-G3-08 is determined by the following critical parameters:

• Type & Configuration: Steering (Rail to Rail) topology with 4 unidirectional channels
• Voltage Specifications: Reverse standoff voltage of 5.5V (Max), breakdown voltage minimum of 6.9V, and clamping voltage of 15V
• Current Rating: Peak pulse current of 3A (8/20µs) or higher
• Package Compatibility: 10-UFDFN surface mount package
• Compliance: ROHS3 compliance and MSL 1 rating
• Application: HDMI protection

The RCLAMP0584J.TCT from Semtech Corporation meets these substitution criteria with compatible electrical parameters and identical package specifications.

Parameter Comparison

Engineering Selection Recommendations

The RCLAMP0584J.TCT is a direct substitute for the obsolete VBUS54GD-FBL-G3-08. Both components share identical package specifications (10-UFDFN), matching clamping voltage (15V), and equivalent channel configuration (4 unidirectional channels). The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The RCLAMP0584J.TCT provides enhanced performance characteristics: higher peak pulse current rating (5A versus 3A) and increased power dissipation capability (75W versus 45W). Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity ratings. The substitute part extends the operating temperature range to -55°C, providing broader thermal coverage compared to the original part's -40°C minimum.

Frequently Asked Questions (FAQ)

Q: Can the RCLAMP0584J.TCT directly replace the VBUS54GD-FBL-G3-08 in existing designs?

A: Yes. Both components share identical package specifications (10-UFDFN), matching clamping voltage (15V), and equivalent steering topology with 4 unidirectional channels. Pin-to-pin compatibility is maintained.

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

A: The substitute part offers higher current handling (5A versus 3A) and greater power dissipation (75W versus 45W).
