| FFF Compatibility | Identical 144-pin CSPBGA (13x13mm) package footprint and pin assignment.Same package style and mechanical dimensions.Exceeds operating temperature range; identical timing, electrical, and register map specifications. | Uses a larger 400-pin PBGA (27x27mm) package compared to the 144-pin CSBGA (13x13mm).Different package physical size and pin count require a complete board layout redesign.Performs all quad DS3/E3 framer duties while adding integrated transceiver capabilities. | ||
 AI Summary | DS3144 by Analog Devices: Telecom IC Framer, Line Interface Unit (LIU) 144-CSPBGA (13x13). | This is the direct industrial-grade sibling of the DS3144. It is pin-for-pin compatible and functionally identical, offering an upgraded temperature operating range of -40°C to +85°C. Although officially obsolete from the original manufacturer, it is widely supported in legacy networks and can be sourced via authorized aftermarket distributors like Rochester Electronics.
| The DS3174+ is a next-generation single-chip transceiver (SCT) combining a Quad DS3/E3 Framer and Quad LIU. While it requires a board redesign due to its larger 400-pin PBGA package, it serves as the official evolutionary migration path for systems utilizing separate DS3144 framers and discrete LIUs.

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 Analog Devices DS3144 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 Analog Devices DS3144 are the DS3144N+ (Analog Devices Inc./Maxim Integrated) and the DS3174+ (Analog Devices Inc./Maxim Integrated), 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 DS3144 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 DS3144 (Analog Devices) is a part in the Interface category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
