Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP3393EY-LF-Z are qualified based on the following critical parameters:

• DC DC Controller topology with step-up (boost) configuration
• 8 output channels for LED driver applications
• Supply voltage range compatibility (minimum 9V input requirement)
• Analog and PWM dimming capability
• Operating temperature range of -40°C to 125°C
• Surface mount packaging in SOIC or equivalent form factor
• ROHS3 compliance and active product status

The LT3760EFE#TRPBF from Analog Devices Inc. meets these substitution criteria through functional equivalence in topology, output configuration, dimming methods, and thermal operating range, despite differences in package form factor and frequency specification.

Parameter Comparison

Engineering Selection Recommendations

Both the MP3393EY-LF-Z and LT3760EFE#TRPBF are active products with ROHS3 compliance and equivalent functional specifications for LED driver controller applications. The MP3393EY-LF-Z operates at 140kHz switching frequency with a 9V to 32V supply range. The LT3760EFE#TRPBF provides a wider supply voltage window (6V to 40V) and adjustable frequency operation (100kHz to 1MHz), with a narrower package footprint in 28-TSSOP form factor compared to the 28-SOIC package of the main part.

Selection between these parts depends on PCB layout constraints, supply voltage requirements, and package compatibility with existing board designs. Both devices support identical dimming methods and thermal operating ranges required for backlight applications.

Frequently Asked Questions (FAQ)

Q: Can the LT3760EFE#TRPBF directly replace the MP3393EY-LF-Z on an existing PCB?

A: Direct replacement requires PCB layout modification due to package form factor differences. The MP3393EY-LF-Z uses 28-SOIC (0.295" width) while the LT3760EFE#TRPBF uses 28-TSSOP (0.173" width) with exposed pad. Pin-to-pin compatibility must be verified against schematic requirements.

Q: What are the key functional equivalencies between these parts?

A: Both devices are 8-output LED driver controllers with step-up (boost) topology, support analog and PWM dimming, operate across -40°C to 125°C, and comply with ROHS3 standards. Both are active products from established manufacturers.

Q: How do the supply voltage ranges differ?

A: The MP3393EY-LF-Z operates from 9V to 32V. The LT3760EFE#TRPBF operates from 6V to 40V, providing extended range capability for applications requiring lower input voltages or higher maximum supply levels.

Q: Are there frequency differences between these controllers?

A: The MP3393EY-LF-Z operates at a fixed 140kHz switching frequency. The LT3760EFE#TRPBF supports adjustable frequency from 100kHz to 1MHz, allowing optimization for specific application requirements.

Q: What is the moisture sensitivity level difference?

A: The MP3393EY-LF-Z has MSL 3 (168 hours). The LT3760EFE#TRPBF has MSL 1 (unlimited), indicating lower moisture sensitivity and potentially less stringent storage requirements.
