|---|---|---|---|
| FFF Compatibility | The ST7580 is housed in a 48-pin VFQFPN package, making it pinout and footprint incompatible with the 28-pin HTSSOP of the ST7540.The physical package style, footprint, and lead pitch differ significantly, requiring a board redesign.Functionally equivalent or better, serving as a narrowband power line networking SoC that supports FSK modulation and operates in the same temperature range. | The MPL360B is housed in a 48-pin QFN or TQFP package, which does not match the 28-pin HTSSOP land pattern of the ST7540.The physical package shape, size, and mounting structure are entirely different, demanding a hardware layout revision.Capable of handling the same narrowband PLC tasks, but operates with a programmable architecture rather than fixed registers. | |
 AI Summary | ST7540 by STMicroelectronics: 1/1 Transceiver Half 28-HTSSOP. | The ST7580 is the recommended active successor from STMicroelectronics. It offers full functional compatibility, supporting FSK modulation along with advanced S-FSK and N-PSK modes, although it requires a board redesign to accommodate the 48-VFQFPN package.
| The MPL360B is an active, highly versatile alternative from Microchip Technology. It is a programmable narrowband PLC modem that supports any protocol below 500 kHz, offering a robust second-source solution that eliminates dependency on STMicroelectronics.

You searched one part. Parter watches your whole BOM.
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 STMicroelectronics ST7540 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 STMicroelectronics ST7540 are the ST7580 (STMicroelectronics) and the MPL360B-I/SCB (Microchip Technology). Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the ST7540 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 ST7540 (STMicroelectronics) is a part in the Interface category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
