Parameter Comparison

Engineering Selection Recommendations

The LM5007MMX/NOPB is the direct substitute for the obsolete LM5007MMX. Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in existing designs.

The LM5007MMX/NOPB offers two significant advantages over the original part:

Product Status: The LM5007MMX/NOPB maintains Active product status, ensuring long-term availability and manufacturer support. The original LM5007MMX is classified as Obsolete, presenting supply chain risk.

Compliance: The LM5007MMX/NOPB is ROHS3 Compliant, meeting current environmental and regulatory requirements. The original LM5007MMX is RoHS non-compliant, which may restrict use in applications subject to RoHS regulations.

Both parts maintain identical Moisture Sensitivity Level (MSL 1 - Unlimited) and REACH Unaffected status. Selection of the LM5007MMX/NOPB is recommended for new designs and ongoing production to ensure regulatory compliance and supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the LM5007MMX/NOPB be used as a direct replacement for the LM5007MMX?

A: Yes. The LM5007MMX/NOPB is a direct substitute with identical electrical specifications, output voltage range (2.5V to 73V), output current (500mA), input voltage range (9V to 75V), operating temperature range (-40°C to 125°C), and 8-TSSOP/8-MSOP package configuration. No circuit modifications are required.

Q: What is the difference between LM5007MMX and LM5007MMX/NOPB?

A: The primary differences are product status and compliance. The LM5007MMX is Obsolete and RoHS non-compliant. The LM5007MMX/NOPB is Active and ROHS3 Compliant. Electrical and mechanical specifications are identical.

Q: Why is the LM5007MMX classified as Obsolete?

A: Obsolete classification indicates the manufacturer has discontinued production and support. The LM5007MMX/NOPB is the active equivalent and recommended for all new and ongoing applications.

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 mechanical dimensions.

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

A: The "/NOPB" suffix indicates the part is supplied in Cut Tape (CT) and Digi-Reel packaging formats without lead (Pb) plating, consistent with RoHS3 compliance requirements.

Q: Can I use the LM5007MMX in new designs?

A: The LM5007MMX is Obsolete and RoHS non-compliant. The LM5007MMX/NOPB is recommended for all new designs to ensure long-term availability, regulatory compliance, and manufacturer support.
