LM2830XMFX Equivalent & Substitute Parts
Part Overview
The LM2830XMFX is a buck switching regulator IC from Texas Instruments designed for positive adjustable output applications. It delivers 1A output current with an adjustable output voltage range from 0.6V to 4.5V, operating from a 3V to 5.5V input supply. The device is housed in a SC-74A (SOT-753) surface mount package and operates across the industrial temperature range of -40°C to 125°C.
The LM2830XMFX is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications utilizing this regulator topology.

Engineering Selection Recommendations
The LM2830XMFX/NOPB is the direct equivalent for the obsolete LM2830XMFX. Both parts share identical electrical characteristics and package specifications. The primary distinction is product status and regulatory compliance: the LM2830XMFX/NOPB is currently in active production and carries ROHS3 compliance certification, whereas the original LM2830XMFX is obsolete and RoHS non-compliant.
For new designs or production continuity, the LM2830XMFX/NOPB is the appropriate selection. Both parts maintain equivalent moisture sensitivity levels and REACH status. The transition from the obsolete variant to the active equivalent presents no functional or electrical impact on circuit performance.
Frequently Asked Questions (FAQ)
Q: Can the LM2830XMFX/NOPB be used as a direct replacement for the LM2830XMFX?
A: Yes. The LM2830XMFX/NOPB is a direct manufacturer equivalent with identical electrical specifications, output voltage range (0.6V to 4.5V), output current (1A), switching frequency (1.6MHz), and SC-74A (SOT-753) package configuration. No circuit modifications are required.
Q: What is the primary difference between these two parts?
A: The LM2830XMFX is obsolete, while the LM2830XMFX/NOPB is in active production. The latter carries ROHS3 compliance certification. Electrical performance and package form factor are identical.
Q: Are there any package or pinout differences?
A: No. Both parts use the SC-74A (SOT-753) surface mount package with SOT-23-5 supplier device package designation. Pinout and footprint are identical.
Q: What does the "/NOPB" suffix indicate?
A: The "/NOPB" suffix indicates the part is supplied without plumbum (lead-free), reflecting RoHS3 compliance and modern manufacturing standards.
Q: Can these parts be used interchangeably in existing PCB designs?
A: Yes. The identical package, pinout, and electrical specifications ensure direct interchangeability without PCB redesign or layout modifications.
