LM5010ASD Equivalent & Substitute Parts

Part Overview

The LM5010ASD is a buck switching regulator IC from Texas Instruments designed for step-down voltage conversion applications. It delivers positive adjustable output from 2.5V to 70V with 1A output current capability across an input range of 6V to 75V. The device operates at switching frequencies between 100kHz and 1MHz and is housed in a 10-WDFN exposed pad surface mount package.

The LM5010ASD carries a Last Time Buy product status, indicating this part number variant is being phased out. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for new production runs and long-term inventory planning.

Substitute Part Grouping Explanation

Substitution eligibility for the LM5010ASD is determined by strict equivalence across the following critical parameters:

• Functional topology: Buck (step-down) switching regulator
• Output configuration: Positive adjustable
• Voltage specifications: Input 6V–75V, Output 2.5V–70V adjustable
• Current rating: 1A output
• Switching frequency range: 100kHz–1MHz
• Package type: 10-WDFN exposed pad
• Surface mount configuration
• Operating temperature range: -40°C to 150°C
• RoHS3 compliance and MSL Level 1

The LM5010ASD/NOPB qualifies as a direct substitute based on identical electrical specifications, package configuration, and thermal performance. The primary distinction is packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and product status transition (Last Time Buy to Active).

Parameter Comparison

Engineering Selection Recommendations

The LM5010ASD/NOPB is the manufacturer-recommended substitute for the LM5010ASD. Both parts are ROHS3 compliant and carry identical electrical and thermal specifications. The transition from Last Time Buy to Active product status for the LM5010ASD/NOPB ensures long-term availability and supply chain stability.

Selection between these part numbers is determined by packaging requirements. The LM5010ASD/NOPB offers flexibility through Cut Tape and Digi-Reel packaging options, suitable for mixed-volume production environments. The original LM5010ASD in Tape & Reel format remains suitable for high-volume manufacturing runs where reel-based pick-and-place automation is standard.

Both variants maintain identical PCB footprint compatibility and require no circuit design modifications for substitution.

Frequently Asked Questions (FAQ)

Q: Can the LM5010ASD/NOPB be used as a direct replacement for the LM5010ASD?

A: Yes. Both parts share identical electrical specifications, thermal performance, package dimensions, and pinout. No circuit modifications are required. The difference is packaging format and product lifecycle status.

Q: What is the significance of the "/NOPB" suffix?

A: The "/NOPB" designation indicates the part is supplied without plumbum (lead-free). Both the LM5010ASD and LM5010ASD/NOPB are RoHS3 compliant and lead-free.

Q: Why is the LM5010ASD marked as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments is transitioning this specific part number variant. The LM5010ASD/NOPB in Active status is the recommended path forward for new designs and ongoing production.

Q: Are there packaging compatibility concerns when switching between Tape & Reel and Cut Tape formats?

A: No electrical or functional compatibility issues exist. Packaging format selection depends on manufacturing equipment and volume requirements. Cut Tape and Digi-Reel formats support lower-volume and mixed-component assembly processes, while Tape & Reel is optimized for high-speed automated reel-fed systems.

Q: Do both parts require identical PCB layout and thermal management?

A: Yes. The 10-WDFN exposed pad package is identical for both parts. PCB footprint, thermal via placement, and copper area requirements remain unchanged.

Q: What is the inventory status for these parts?

A: The LM5010ASD has 947 pieces in stock (Last Time Buy status). The LM5010ASD/NOPB has 2300 pieces in stock (Active status), providing greater availability for ongoing procurement.
