LM5007MM Equivalent & Substitute Parts

Part Overview

The LM5007MM is a buck switching regulator IC from Texas Instruments designed for step-down voltage conversion with positive adjustable output. It delivers 500mA output current across an input voltage range of 9V to 75V, with adjustable output voltage from 2.5V to 73V. The device is housed in an 8-TSSOP/8-MSOP surface mount package and operates across the industrial temperature range of -40°C to 125°C.

The LM5007MM carries a Last Time Buy product status, indicating this packaging variant is being discontinued. Identifying equivalent 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 LM5007MM is determined by strict equivalence across the following critical parameters:

• Base product number (LM5007 series)
• Functional topology (buck step-down regulator)
• Output configuration (positive adjustable)
• Electrical specifications (input voltage range 9V–75V, output voltage range 2.5V–73V, 500mA output current)
• Package type (8-TSSOP/8-MSOP surface mount)
• Operating temperature range (-40°C to 125°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The LM5007MM/NOPB is the direct equivalent substitute, differing only in packaging format (Cut Tape and Digi-Reel versus Digi-Reel only) and product status (Active versus Last Time Buy).

Parameter Comparison

Engineering Selection Recommendations

The LM5007MM/NOPB is the direct functional and electrical equivalent to the LM5007MM. Both devices share identical electrical specifications, package geometry, and compliance certifications. The primary distinction is product lifecycle status: the LM5007MM is designated Last Time Buy, while the LM5007MM/NOPB maintains Active status with higher inventory availability (17,200 units versus 6,049 units).

For new designs and ongoing production, the LM5007MM/NOPB is the appropriate selection. The /NOPB suffix indicates lead-free plating and RoHS3 compliance, consistent with the original part. Packaging availability in both Cut Tape and Digi-Reel formats provides flexibility for different procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can the LM5007MM/NOPB be used as a direct replacement for the LM5007MM?

A: Yes. Both parts are electrically and mechanically identical. They share the same base product number (LM5007), electrical specifications, package type (8-TSSOP/8-MSOP), and compliance certifications. The only differences are product status and packaging format options.

Q: What does the /NOPB suffix indicate?

A: The /NOPB suffix denotes lead-free plating and RoHS3 compliance. Both the LM5007MM and LM5007MM/NOPB are ROHS3 compliant, so this designation reflects manufacturing process rather than functional difference.

Q: Why is the LM5007MM marked as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments is discontinuing this specific packaging variant. The LM5007MM/NOPB remains in active production with the same electrical and mechanical specifications, ensuring continued availability.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 8-TSSOP/8-MSOP (0.118", 3.00mm Width) surface mount package with identical pinout and footprint. PCB designs require no modification for substitution.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control measures. Standard handling procedures apply without special desiccant or baking requirements.

Q: Are both parts REACH compliant?

A: Yes. Both the LM5007MM and LM5007MM/NOPB carry REACH Unaffected status, confirming compliance with EU chemical regulations.
