LM2675M-12 Equivalent & Substitute Parts

Part Overview

The LM2675M-12 is a buck switching regulator IC from Texas Instruments' SIMPLE SWITCHER® series, designed for step-down voltage conversion with a fixed 12V output at 1A maximum current. This device operates across a wide input voltage range of 6.5V to 40V and is housed in an 8-SOIC surface mount package. The main part number LM2675M-12 is currently in Last Time Buy status with 1350 pieces available in stock. Finding equivalent or substitute parts is necessary due to the product's end-of-life designation, ensuring design continuity and supply chain reliability for new production runs or long-term support requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM2675M-12 is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 12V
• Output current rating of 1A
• Input voltage range of 6.5V to 40V minimum
• Switching frequency of 260kHz
• 8-SOIC package configuration (0.154", 3.90mm Width)
• Operating temperature range of -40°C to 125°C
• Surface mount mounting type
• Buck topology with positive output configuration
• Single output configuration
• No synchronous rectifier requirement

The LM2675M-12/NOPB is classified as the manufacturer-recommended substitute. This part maintains identical electrical specifications and physical packaging while differing only in product status and inventory availability. The "/NOPB" suffix indicates lead-free plating compliance and represents the active production variant of the same base product number LM2675.

Parameter Comparison

Engineering Selection Recommendations

The LM2675M-12/NOPB is the direct equivalent for the LM2675M-12. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications. The primary distinction is product lifecycle status: the LM2675M-12 is designated Last Time Buy, while the LM2675M-12/NOPB maintains Active status with higher inventory availability.

For new designs or production runs requiring long-term component availability, the LM2675M-12/NOPB is the appropriate selection. Both parts satisfy ROHS3 compliance and REACH unaffected requirements. The identical operating temperature range, package configuration, and electrical performance ensure direct pin-for-pin and functional compatibility in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the LM2675M-12/NOPB be used as a direct replacement for the LM2675M-12?

A: Yes. Both parts are electrically and mechanically identical. The LM2675M-12/NOPB is the active production variant and serves as the manufacturer-recommended substitute for the Last Time Buy LM2675M-12.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" suffix denotes lead-free plating compliance. This represents the current manufacturing standard for the LM2675 base product number.

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

A: No. Both parts use the identical 8-SOIC (0.154", 3.90mm Width) package with the same pinout configuration. PCB layouts and component placement require no modification.

Q: What is the significance of the Last Time Buy status?

A: Last Time Buy status indicates that the LM2675M-12 is no longer in active production. Existing inventory is available for purchase, but no future manufacturing runs are planned. The LM2675M-12/NOPB is the recommended alternative for ongoing supply.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LM2675M-12 and LM2675M-12/NOPB are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: Can I mix these parts in the same production batch?

A: Yes. The electrical and mechanical equivalence permits interchangeable use within the same design and production environment.
