LM25007SD Equivalent & Substitute Parts

Part Overview

The LM25007SD 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 42V, with adjustable output voltage from 2.5V to 37V. The device operates at switching frequencies up to 800kHz and is housed in an 8-WDFN exposed pad surface mount package.

The LM25007SD is classified as obsolete. Finding equivalent or substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for new designs or production runs.

Substitute Part Grouping Explanation

Substitution for the LM25007SD is determined by strict equivalence across the following critical parameters:

  • Function and topology (step-down buck converter)
  • Output configuration (positive adjustable)
  • Electrical specifications (input voltage range 9V–42V, output voltage range 2.5V–37V, 500mA output current)
  • Switching frequency (up to 800kHz)
  • Package type (8-WDFN exposed pad, 8-WSON 4x4)
  • Operating temperature range (-40°C to 125°C)
  • Mounting type (surface mount)

The LM25007SD/NOPB is identified as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations

The LM25007SD is obsolete and no longer in active production. The LM25007SD/NOPB is the direct functional equivalent and is currently in active production status with full inventory availability.

Selection of LM25007SD/NOPB is supported by:

  • Identical electrical and mechanical specifications
  • Active product status ensuring long-term supply chain support
  • ROHS3 compliance, meeting current regulatory requirements for new designs
  • Equivalent moisture sensitivity level and REACH status
  • Availability in standard packaging formats (Cut Tape and Digi-Reel)

For applications requiring RoHS non-compliant components, the original LM25007SD remains available in limited inventory. For new designs and production continuity, LM25007SD/NOPB is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can LM25007SD/NOPB be used as a direct replacement for LM25007SD?

A: Yes. Both devices are electrically and mechanically identical across all specified parameters including input/output voltage ranges, output current, switching frequency, package type, and operating temperature range. The primary differences are product status and RoHS compliance certification.

Q: What is the difference between LM25007SD and LM25007SD/NOPB?

A: The LM25007SD is obsolete, while LM25007SD/NOPB is in active production. LM25007SD/NOPB carries ROHS3 compliance certification, whereas LM25007SD is RoHS non-compliant. Both share identical functional specifications and the same 8-WSON (4x4) package footprint.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-WDFN exposed pad package with 8-WSON (4x4) supplier device package designation. Pinout and footprint are identical, allowing direct PCB substitution without layout modifications.

Q: Which part should be selected for new designs?

A: LM25007SD/NOPB is recommended for new designs due to active production status, ROHS3 compliance, and assured long-term availability. The obsolete LM25007SD should be reserved for legacy system support only.

Q: Are there inventory considerations when selecting between these parts?

A: LM25007SD/NOPB has significantly higher inventory availability (4300 Pcs) compared to LM25007SD (1160 Pcs). For production planning and supply chain reliability, LM25007SD/NOPB is the preferred choice.
