| FFF Compatibility | The NTE1508 uses the exact same 18-DIP package and identical pinout as the LM3914N-1/NOPB.The physical package dimensions and through-hole mounting type are fully identical to the original part.It functions identically as an autonomous 10-step linear dot/bar LED display driver with a built-in voltage reference. | The 20-PLCC package is a surface-mount design that has a different footprint and pin count compared to the 18-DIP.Requires a surface-mount layout rather than through-hole mounting, or an adapter socket.Electrically and functionally identical to the original, providing a 10-step linear bar/dot display response. | ||
 AI Summary | LM3914N-1/NOPB by Texas Instruments: LED, LCD, Vacuum Fluorescent (VF) Driver 18-DIP. | The NTE1508 is a direct second-source drop-in replacement specifically designed to replace the obsolete LM3914 in the same 18-DIP footprint. It retains all the autonomous analog voltage sensing capabilities and current-regulated outputs of the original.
| The LM3914V/NOPB is the surface-mount PLCC-20 sibling of the DIP-packaged original. While functionally identical, this alternative also faces obsolescence and requires a footprint redesign or a PLCC-to-DIP adapter.

All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Texas Instruments LM3914N-1/NOPB is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Texas Instruments LM3914N-1/NOPB are the NTE1508 (NTE Electronics) and the LM3914V/NOPB (Texas Instruments), out of 3 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the LM3914N-1/NOPB are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The LM3914N-1/NOPB (Texas Instruments) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
