LP8501TMX/NOPB Equivalent & Substitute Parts

Part Overview

The LP8501TMX/NOPB is an active LED driver IC manufactured by Texas Instruments, designed for backlight applications requiring multi-channel output regulation. This device integrates a 9-output DC-DC regulator using switched capacitor (charge pump) topology with PWM dimming capability. The part is ROHS3 compliant and maintains unlimited moisture sensitivity level (MSL 1), making it suitable for consumer and industrial backlight systems. Substitute parts are identified based on matching electrical specifications, topology, and package compatibility to ensure functional equivalence in target applications.

Substitute Part Grouping Explanation

Substitute parts for the LP8501TMX/NOPB are identified through parametric equivalence. The critical parameters determining substitution eligibility are:

• Topology: Switched Capacitor (Charge Pump)
• Number of Outputs: 9
• Supply Voltage Range: 2.7V to 5.5V
• Output Voltage: 4.5V
• Current per Channel: 25.5mA
• Switching Frequency: 1.25MHz
• Dimming Method: PWM
• Package: 25-WFBGA (25-uSMD)
• Operating Temperature Range: -30°C to 85°C

The LP8501TME/NOPB qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications, topology, output configuration, and thermal operating range. The primary difference is packaging format: the main part uses standard packaging while the substitute is supplied in Tape & Reel (TR) format. This distinction affects procurement and assembly logistics but does not alter functional performance or electrical characteristics.

Engineering Selection Recommendations

Both the LP8501TMX/NOPB and LP8501TME/NOPB are active products from Texas Instruments with identical electrical and thermal specifications. Selection between these parts should be based on procurement and assembly requirements:

• Choose LP8501TMX/NOPB for standard packaging requirements or when bulk quantities are sourced through conventional distribution channels.
• Choose LP8501TME/NOPB when Tape & Reel format is required for automated assembly processes or high-volume production environments.

Both parts maintain ROHS3 compliance and unlimited MSL rating, ensuring compatibility with modern manufacturing and environmental standards. No functional performance difference exists between the two variants.

Frequently Asked Questions (FAQ)

Q: Can LP8501TME/NOPB be used as a direct replacement for LP8501TMX/NOPB?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, topology, output configuration, and thermal operating range. The only difference is packaging format (Tape & Reel vs. standard). Functional performance and circuit behavior are equivalent.

Q: What determines if a part qualifies as a substitute for the LP8501TMX/NOPB?

A: Substitution eligibility is determined by matching the following parameters: DC-DC regulator topology (switched capacitor charge pump), 9-output configuration, 2.7V to 5.5V supply range, 4.5V output voltage, 25.5mA per-channel current, 1.25MHz switching frequency, PWM dimming capability, 25-WFBGA package, and -30°C to 85°C operating temperature range.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and standard packaging formats contain identical die and electrical components. The packaging format only affects procurement logistics, storage, and automated assembly compatibility. Electrical characteristics, thermal performance, and functional behavior remain unchanged.

Q: Are both parts suitable for backlight applications?

A: Yes. Both the LP8501TMX/NOPB and LP8501TME/NOPB are specified for backlight applications and maintain identical performance characteristics across the full operating temperature range of -30°C to 85°C.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning the component can be stored indefinitely without moisture bake-out requirements prior to soldering. This simplifies inventory management and reduces manufacturing constraints.
