Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM2674M-12 is determined by strict equivalence across the following critical parameters:

• Output voltage configuration (12V fixed)
• Output current capability (500mA minimum)
• Input voltage operating range (6.5V to 40V)
• Package type (8-SOIC form factor)
• Switching topology (buck converter)
• Operating temperature range (-40°C to 125°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The LM2674M-12/NOPB represents the manufacturer-recommended equivalent, maintaining identical electrical specifications and package configuration while offering active product status for continued availability.

Parameter Comparison

Engineering Selection Recommendations

The LM2674M-12/NOPB is the direct equivalent for the LM2674M-12. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications. The primary distinction is product lifecycle status: the LM2674M-12 is designated Last Time Buy, while the LM2674M-12/NOPB maintains Active status, ensuring continued availability and supply chain support.

For new designs or ongoing production requiring long-term component availability, the LM2674M-12/NOPB is the appropriate selection. Both parts satisfy ROHS3 compliance and REACH requirements, with equivalent moisture sensitivity ratings and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the LM2674M-12/NOPB be used as a direct replacement for the LM2674M-12?

A: Yes. Both parts are electrically and mechanically identical, with matching output voltage (12V), output current (500mA), input voltage range (6.5V to 40V), package type (8-SOIC), and operating temperature specifications (-40°C to 125°C). The "/NOPB" suffix indicates lead-free plating and does not affect functional compatibility.

Q: What does the Last Time Buy status mean for the LM2674M-12?

A: Last Time Buy indicates the manufacturer will no longer accept new orders after a specified date. Existing inventory may remain available, but long-term procurement should transition to the active equivalent, LM2674M-12/NOPB.

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

A: No. Both parts operate across the same temperature range (-40°C to 125°C junction temperature) and share identical switching frequency (260kHz) and output current specifications (500mA).

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LM2674M-12 and LM2674M-12/NOPB are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: Can I use these parts in existing PCB designs without layout modifications?

A: Yes. Both parts use the identical 8-SOIC package (0.154", 3.90mm width), requiring no changes to PCB footprints or component placement.
