AI Summary	TF-021B-H265 by SOFNG: Micro SD card (TF card) Connector and Ejector Push-Pull Surface Mount.	Molex 104031-0811 is an active, high-reliability push-pull microSD card connector designed for surface-mount applications. It provides the same standard 8-pin microSD pin assignment as the SOFNG TF-021B-H265 while offering improved contact current capacity and wider operating temperature margins. Because memory socket body dimensions and PCB solder pad layouts vary by manufacturer, PCB footprint redesign is required. Standard 8-pin microSD electrical interface Higher contact current rating (0.5A per pin vs 25mA) Wider operating temperature range (-25°C to +85°C vs +75°C max) Different PCB solder pad layout and shell ground tabs requiring PCB redesign Lower profile height above board (1.42mm vs 2.50mm)	Würth Elektronik 693072010801 (WR-CRD series) is an active, 8-position SMT microSD card connector with a push-pull insertion/removal mechanism. Like the queried SOFNG part, it is a streamlined 8-pin socket without an integrated detect switch, ensuring direct functional parity while requiring PCB pad layout updates. Standard 8-pin microSD electrical interface No card detect switch required, matching original non-switch topology Higher contact current rating (0.5A vs 25mA) Different PCB land pattern and shell tab placement requiring board update Lower profile height above board (1.75mm vs 2.50mm)

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.
