SP7616ER-L Equivalent & Substitute Parts

Part Overview

The SP7616ER-L is a linear LED driver IC manufactured by MaxLinear, Inc., designed for 4-output backlight applications with analog and PWM dimming capabilities. This device operates across a wide supply voltage range of 4.5V to 30V and delivers 60mA per output channel in an 8-DFN (2x3) surface mount package.

The SP7616ER-L has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SP7616ER-L are identified based on the following core electrical and mechanical parameters:

Primary Matching Criteria:

• 4-output linear LED driver topology
• Backlight application suitability
• Surface mount packaging
• Internal switching capability
• Dimming control functionality (analog, PWM, or I2C)

Secondary Compatibility Factors:

• Supply voltage range overlap or compatibility with system design
• Output current per channel capability
• Operating temperature range
• Moisture sensitivity classification
• RoHS and REACH compliance status

The identified substitutes maintain the fundamental 4-output linear driver architecture and backlight application focus. However, differences exist in supply voltage ranges, output current specifications, dimming control methods, and package configurations. These differences require engineering evaluation based on specific circuit requirements and design constraints.

Engineering Selection Recommendations

LP5562TMX/NOPB (Texas Instruments)

The LP5562TMX/NOPB is an active product with ROHS3 compliance and REACH unaffected status. This device maintains the 4-output linear driver architecture and backlight application focus. The I2C dimming interface provides digital control capability. The 12-DSBGA package differs from the original 8-DFN form factor, requiring PCB layout modification. Supply voltage range (2.7V to 5.5V) is narrower than the SP7616ER-L, and output current per channel (25.5mA) is reduced. This substitute is suitable for designs where lower supply voltages are acceptable and I2C control integration is feasible.

TPS75105YFFR (Texas Instruments)

The TPS75105YFFR is an active product with ROHS3 compliance and REACH unaffected status. This device maintains the 4-output linear driver topology and PWM dimming control method, aligning with the original SP7616ER-L dimming approach. The 9-DSBGA package requires PCB layout modification compared to the original 8-DFN package. Supply voltage range (2.7V to 5.5V) is narrower than the SP7616ER-L, and output current per channel (25mA) is reduced. This substitute is suitable for designs where PWM dimming control is required and lower supply voltages are compatible with system requirements.

Both substitutes offer active product status and modern compliance certifications, providing long-term supply chain stability compared to the obsolete SP7616ER-L.

Frequently Asked Questions (FAQ)

Q: Can the LP5562TMX/NOPB directly replace the SP7616ER-L without circuit modifications?

A: Direct replacement is not possible. The LP5562TMX/NOPB uses I2C dimming control instead of analog/PWM, operates at lower supply voltages (2.7V to 5.5V versus 4.5V to 30V), delivers lower output current per channel (25.5mA versus 60mA), and uses a 12-DSBGA package instead of 8-DFN. Circuit redesign is required.

Q: Can the TPS75105YFFR directly replace the SP7616ER-L without circuit modifications?

A: Direct replacement is not possible. The TPS75105YFFR operates at lower supply voltages (2.7V to 5.5V versus 4.5V to 30V), delivers lower output current per channel (25mA versus 60mA), and uses a 9-DSBGA package instead of 8-DFN. However, PWM dimming control is maintained. Circuit redesign is required.

Q: What are the key differences between the two substitute options?

A: The LP5562TMX/NOPB uses I2C digital control with 256Hz and 558Hz frequency options, while the TPS75105YFFR uses PWM analog control. The LP5562TMX/NOPB delivers slightly higher output current per channel (25.5mA versus 25mA). Both operate at identical supply voltage ranges and use BGA packages with different pin counts.

Q: Are both substitute parts RoHS and REACH compliant?

A: Yes. Both the LP5562TMX/NOPB and TPS75105YFFR are ROHS3 compliant and REACH unaffected, meeting modern environmental and regulatory requirements.

Q: What package considerations apply when selecting a substitute?

A: The original SP7616ER-L uses an 8-DFN (2x3) package. The LP5562TMX/NOPB uses a 12-DSBGA package, and the TPS75105YFFR uses a 9-DSBGA package. Both substitutes require PCB layout redesign to accommodate the different package footprints and pin configurations.

Q: Which substitute is better for high-voltage applications?

A: Neither substitute supports the full 4.5V to 30V supply range of the SP7616ER-L. Both are limited to 2.7V to 5.5V. For applications requiring higher supply voltages, alternative LED driver solutions outside this substitute group must be evaluated.

Q: What is the operating temperature difference between the original and substitutes?

A: The SP7616ER-L operates from -40°C to 100°C (junction temperature). Both substitutes operate from -40°C to 85°C (ambient or junction temperature). Applications requiring operation above 85°C may not be compatible with these substitutes.
