Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM2674M-5.0 is determined by strict equivalence across the following critical parameters:

• Output voltage configuration (5V fixed)
• Output current capability (500mA minimum)
• Input voltage operating range (6.5V to 40V)
• Package type (8-SOIC form factor)
• Switching topology (buck converter)
• Thermal operating range (-40°C to 125°C)

The LM2674M-5.0/NOPB qualifies as a direct manufacturer-recommended substitute, maintaining identical electrical specifications and package configuration while differing only in lead-free processing designation and supplier device package coding.

Parameter Comparison

Engineering Selection Recommendations

The LM2674M-5.0/NOPB is the designated manufacturer-recommended substitute for the LM2674M-5.0. Both parts maintain identical electrical performance specifications and physical packaging. The primary distinction is product lifecycle status: the original LM2674M-5.0 is designated Last Time Buy, while the LM2674M-5.0/NOPB maintains Active status, ensuring continued availability and manufacturing support.

Both variants satisfy ROHS3 compliance requirements and carry MSL Level 1 moisture sensitivity ratings, supporting unlimited shelf life under standard storage conditions. Selection between these parts should prioritize the active-status LM2674M-5.0/NOPB for new designs and long-term procurement strategies.

Frequently Asked Questions (FAQ)

Q: What is the difference between LM2674M-5.0 and LM2674M-5.0/NOPB?
