LM3533TMX-40A/NOPB Equivalent & Substitute Parts

Part Overview

The LM3533TMX-40A/NOPB is an active LED driver IC manufactured by Texas Instruments, classified as a Power Management PMIC. This device integrates a 7-output DC-DC regulator with step-up (boost) and switched capacitor (charge pump) topologies, delivering 40V output with PWM dimming capability at 30mA per channel. The part is in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical specifications, output topology, and package compatibility align with the main part number across the LM3533 and LM3633 series.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LM3533TMX-40A/NOPB are identified based on strict parametric equivalence across the following criteria:

Primary Equivalence Parameters:

• Voltage supply range: 2.7V to 5.5V
• Output voltage: 40V
• Current per channel: 30mA
• Topology: Step-Up (Boost) and Switched Capacitor (Charge Pump)
• Dimming method: PWM
• Package type: 20-DSBGA
• Operating temperature range: -40°C to 125°C
• RoHS3 compliance and MSL 1 rating

Substitution Categories:

Category 1: Full Parametric Equivalents (7-Output Configuration) Parts LM3533TME-40/NOPB, LM3533TME-40A/NOPB, and LM3533TMX-40/NOPB maintain identical electrical specifications and 7-output architecture. Differences are limited to packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) and temperature grade designation (TME vs. TMX suffix).

Category 2: Reduced Output Configuration (6-Output) Part LM3633YFQR operates within the same electrical parameter set but provides 6 outputs instead of 7. This part is suitable only when application requirements do not mandate all 7 output channels.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status with ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility with the main part LM3533TMX-40A/NOPB.

For 7-Output Applications: LM3533TME-40/NOPB, LM3533TME-40A/NOPB, and LM3533TMX-40/NOPB are direct electrical equivalents. Selection between these parts is determined by packaging requirements (Tape & Reel vs. Cut Tape & Digi-Reel format) and inventory availability. All three maintain identical electrical performance and thermal specifications.

For 6-Output Applications: LM3633YFQR is suitable only when the application design accommodates a single output reduction. This part maintains all other electrical parameters and compliance certifications but is not interchangeable in designs requiring all 7 output channels.

Frequently Asked Questions (FAQ)

Q: Can LM3533TME-40/NOPB replace LM3533TMX-40A/NOPB in production? A: Yes. Both parts share identical electrical specifications, output configuration (7 channels), voltage ratings (2.7V to 5.5V input, 40V output), current capacity (30mA per channel), and package type (20-DSBGA). The difference is packaging format (Tape & Reel). Verify packaging requirements for your assembly process.

Q: What is the difference between LM3533TME-40A/NOPB and LM3533TMX-40/NOPB? A: Both parts are electrically equivalent with 7 outputs and identical electrical parameters. LM3533TME-40A/NOPB is supplied in Cut Tape & Digi-Reel format, while LM3533TMX-40/NOPB is supplied in standard Tape & Reel format. Selection depends on your procurement and assembly equipment compatibility.

Q: Is LM3633YFQR a direct substitute for LM3533TMX-40A/NOPB? A: LM3633YFQR is not a direct substitute. While it maintains the same electrical specifications (2.7V to 5.5V input, 40V output, 30mA per channel, PWM dimming, 20-DSBGA package), it provides only 6 output channels instead of 7. Use this part only if your application design supports reduced output count.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts, including LM3533TME-40/NOPB, LM3533TME-40A/NOPB, LM3533TMX-40/NOPB, and LM3633YFQR, are ROHS3 compliant with MSL 1 rating (unlimited moisture sensitivity).

Q: What packaging formats are available for the LM3533 7-output variants? A: LM3533TMX-40A/NOPB and LM3533TMX-40/NOPB are supplied in Tape & Reel (TR) format. LM3533TME-40A/NOPB is supplied in Cut Tape (CT) & Digi-Reel format. LM3533TME-40/NOPB is supplied in Tape & Reel (TR) format. Confirm packaging compatibility with your assembly equipment before selection.

Q: Can I use LM3633YFQR if I only need 6 LED driver outputs? A: Yes. LM3633YFQR is suitable for applications requiring 6 output channels. It maintains all electrical specifications of the LM3533 series (2.7V to 5.5V input, 40V output, 30mA per channel, PWM dimming) and is packaged in 20-DSBGA format with identical thermal and compliance ratings.
