Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP3378EGF-Z is determined by strict equivalence across the following critical parameters:

• DC-DC controller topology (step-down buck configuration)
• 4-output channel architecture
• Supply voltage range (5V to 24V)
• Per-channel output current (350mA)
• Operating frequency range (150kHz to 590kHz)
• Dimming capability (analog and PWM support)
• Package type (28-TSSOP with exposed pad)
• Operating temperature range (-40°C to 125°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The MP3378GF-Z meets all these criteria and is classified as a parametric equivalent. This substitute maintains identical electrical specifications and mechanical compatibility while offering improved product availability status.

Parameter Comparison

Engineering Selection Recommendations

The MP3378GF-Z is a direct parametric equivalent to the MP3378EGF-Z with identical electrical and mechanical specifications. The primary distinction is product status: the MP3378EGF-Z is discontinued, while the MP3378GF-Z maintains active status with current inventory availability (3461 units in stock versus 50100 units for the discontinued variant).

Both parts carry ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for new designs and production continuity. The MP3378GF-Z is the recommended selection for new procurement due to its active product status and demonstrated supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the MP3378GF-Z be used as a direct replacement for the MP3378EGF-Z?
