Choosing a 4-pin FFC/FPC adapter for computer peripherals comes down to more than finding a connector board with the right pin count. The cable-facing socket pitch, back-side pitch, DIP spacing, board orientation, and quantity all shape which board fits the intended connector arrangement. Here, the central decision is between a right-angle board with a 0.5 mm socket-side pitch and a bent-pin pull-down board with a 1 mm socket-side pitch.
Quick verdict
Pick the 2 x FFC FPC Connector Board 4 Pin Double Row Right Angle Pin Header Adapter when the right-angle format and its 0.5 mm socket-side/1.0 mm back-side pitch configuration match the layout you are working with. It is listed at USD 13.65 and is the two-board option.
Choose the 4Pin 1.0 to 2.54 mm Double Row of Bent Pins Pull-down FFC FPC Adapter Board when the cable side calls for 1 mm pitch and the back side calls for 0.5 mm pitch. Its listed price is USD 14.84. The listed-price spread is USD 1.19, so connector geometry is the more consequential distinction.

Where each board wins
The right-angle board is the better fit for a project that calls for the named right-angle pin-header arrangement and a two-board quantity. Its double-sided board description also makes its layout easy to distinguish from the pull-down alternative.
The bent-pin pull-down board is the direct match for the named double row of bent pins pull-down format. Its 1 mm socket-side and 0.5 mm back-side specification reverses the other board's FPC pitch arrangement, which is the key functional divider between these two 4-pin choices.
Product notes
2 x FFC FPC Connector Board 4 Pin Double Row Right Angle Pin Header Adapter
This selection makes sense when a build requires two matching 4-pin FFC/FPC connector boards and the listed right-angle pin-header style corresponds to the planned connection. The board is described for flexible cables and flexible printed circuit boards in compact electronics applications, including computer peripherals, and it uses a 2.54 mm DIP pitch. Its 32 x 17 mm footprint is slightly shorter in width than the pull-down board. The main limitation is its specific pitch configuration: the socket side is 0.5 mm while the back side is 1.0 mm. That arrangement is not interchangeable with the reversed layout of the other board, so this is a geometry-led choice rather than a general substitute.
4Pin 1.0 to 2.54 mm Double Row of Bent Pins Pull-down FFC FPC Adapter Board
The pull-down board is the focused option for a connector arrangement that uses the title's double-row bent-pins format. It has four pins and a 2.54 mm DIP pitch, with a package description naming one FPC/FFC connector board. Its slightly wider 32 x 17.5 mm overall size may also matter where board dimensions are already set. The limitation is again the defined FPC pitch layout: this board places 1 mm pitch on the socket side and 0.5 mm on the back side. Select it for that specified orientation of pitches, not simply because it is another 4-pin cable connector board.
Final choice by use case
For a paired-board need and a right-angle pin-header format, choose the 2 x FFC FPC Connector Board 4 Pin Double Row Right Angle Pin Header Adapter. For the named pull-down, bent-pin arrangement with the opposite FPC pitch order, choose the 4Pin 1.0 to 2.54 mm Double Row of Bent Pins Pull-down FFC FPC Adapter Board. Both are new uxcell 4-pin cable connectors; the deciding factor is matching the connector layout to the intended cable and board sides.
