LM5007SD Equivalent & Substitute Parts

Part Overview

The LM5007SD 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 73V with a maximum output current of 500mA, operating across an input voltage range of 9V to 75V. The device is housed in an 8-WDFN exposed pad surface mount package and operates reliably across the industrial temperature range of -40°C to 125°C.

The LM5007SD carries a Last Time Buy product status, indicating that this specific packaging variant (Tape & Reel) is being phased out. Identifying qualified substitute parts ensures design continuity and supply chain reliability for new production runs and ongoing support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM5007SD is determined by strict equivalence across the following critical parameters:

• Identical buck topology and step-down function
• Matching output configuration (positive adjustable)
• Equivalent voltage input range (9V to 75V minimum and maximum)
• Equivalent voltage output range (2.5V to 73V minimum and maximum)
• Matching output current rating (500mA)
• Single output configuration
• Identical package type (8-WDFN exposed pad)
• Matching operating temperature range (-40°C to 125°C)
• Equivalent regulatory compliance (ROHS3, REACH Unaffected)

The LM5007SD/NOPB qualifies as a direct substitute based on these parameters. The primary distinction is packaging format: the original part uses Tape & Reel (TR) packaging, while the substitute uses Cut Tape (CT) and Digi-Reel® packaging. Both variants are manufactured by Texas Instruments and share identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The LM5007SD/NOPB is the qualified substitute for the LM5007SD. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters. The LM5007SD carries Last Time Buy status, making the transition to LM5007SD/NOPB necessary for ongoing production and supply continuity.

The substitute part is currently in Active product status, ensuring long-term availability and support. Both variants meet ROHS3 compliance and REACH requirements, maintaining regulatory alignment for applications subject to environmental standards.

The only functional difference is packaging format. The LM5007SD/NOPB uses Cut Tape and Digi-Reel® packaging, which is standard for active production components. This packaging change does not affect electrical performance, thermal characteristics, or board-level integration. PCB footprint and solder reflow profiles remain identical due to matching package geometry (8-WSON 4x4).

Frequently Asked Questions (FAQ)

Q: Can LM5007SD/NOPB be used as a direct replacement for LM5007SD?

A: Yes. Both parts share identical electrical specifications, output characteristics, and package geometry. The only difference is packaging format (Tape & Reel versus Cut Tape/Digi-Reel®). PCB assembly and performance are unaffected by this change.

Q: Why is the LM5007SD marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments is discontinuing this specific packaging variant. The LM5007SD/NOPB represents the active production equivalent and should be used for new designs and ongoing production.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate across the same temperature range (-40°C to 125°C), deliver identical output current (500mA), and support the same voltage input and output ranges (9V to 75V input, 2.5V to 73V output).

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

A: The "/NOPB" suffix indicates "No Plumbum" (lead-free) packaging, confirming ROHS3 compliance. Both the LM5007SD and LM5007SD/NOPB are lead-free and meet the same environmental standards.

Q: Will changing from Tape & Reel to Cut Tape packaging affect assembly?

A: No. Cut Tape and Digi-Reel® packaging are standard formats for automated pick-and-place assembly. The component dimensions, pin configuration, and solder pad layout remain identical. Assembly equipment may require tape feeder adjustments, but electrical and mechanical integration is unchanged.

Q: Are both parts ROHS3 and REACH compliant?

A: Yes. Both LM5007SD and LM5007SD/NOPB are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for applications in restricted substance environments.
