A 4-pin FFC/FPC adapter board can look interchangeable until the cable-side layout and header orientation enter the decision. Here, the key choice is not the $1.19 listed-price spread: it is selecting the board whose stated pitch arrangement and connector form align with the electronics project or computer peripheral you are working on.
Quick verdict
- Choose the 2 x FFC FPC Connector Board 4 Pin Double Row Right Angle Pin Header Adapter when the needed layout has a 0.5 mm FPC socket-side pitch and 1.0 mm back-side pitch.
- Choose the 4Pin 1.0 to 2.54 mm Double Row of Bent Pins Flip-down FFC FPC Adapter Board when the required arrangement reverses that relationship, with a 1 mm socket side and 0.5 mm back side.
- Both are new uxcell cable connectors with four pins and a stated 2.54 mm DIP pitch. Listed prices run from USD 13.65 to USD 14.84.

Where each board wins
Right-angle board: for the named header format
The 2 x FFC FPC Connector Board 4 Pin Double Row Right Angle Pin Header Adapter is the clearer match when a right-angle pin-header adapter is part of the required build. Its title also identifies a double-row arrangement, while the description places the board in flexible-cable and flexible-PCB connections used across compact electronics and computer peripherals. The listed price is the lower of the pair, although the specified connection layout should remain the deciding factor.
Flip-down board: for the reversed cable-side pitch arrangement
The 4Pin 1.0 to 2.54 mm Double Row of Bent Pins Flip-down FFC FPC Adapter Board fits the alternative pitch relationship in this head-to-head comparison. Its bent-pin, flip-down wording distinguishes its form from the right-angle adapter, and its stated board dimensions are 33 x 17.5 mm. Pick it when that named configuration corresponds to the connector arrangement needed for the device rather than choosing solely on the small price difference.
Product notes
2 x FFC FPC Connector Board 4 Pin Double Row Right Angle Pin Header Adapter
This board makes sense for a compact electronics or computer-peripheral project using a four-pin flexible cable or flexible printed circuit board connection. The right-angle pin-header description gives the choice a clear purpose, and its USD 13.65 listed price is the lower figure in the comparison. It is also described as a double-sided board with a single flat-cable socket, which helps define the format being selected. Its limitation is specificity: the board uses a 0.5 mm socket-side pitch and a 1.0 mm back-side pitch, so it is intended for that particular stated arrangement rather than the reversed layout used by the flip-down board.
4Pin 1.0 to 2.54 mm Double Row of Bent Pins Flip-down FFC FPC Adapter Board
Choose this board when the project calls for the four-pin, bent-pin flip-down format named in its title. It is described for connecting flexible cables or flexible printed circuit boards in compact electronic equipment, including computer peripherals, and its 33 x 17.5 mm stated size may help distinguish it from the smaller right-angle board. The limitation is again its defined connector geometry: this board places the 1 mm pitch on the FPC socket side and the 0.5 mm pitch on the back side. That is a concrete layout difference, not a general substitute for the right-angle board's arrangement.
Final choice by use case
For a right-angle header adapter with the 0.5 mm socket-side and 1.0 mm back-side arrangement, select the 2 x FFC FPC Connector Board 4 Pin Double Row Right Angle Pin Header Adapter. For a bent-pin flip-down board with those two pitch values reversed, select the 4Pin 1.0 to 2.54 mm Double Row of Bent Pins Flip-down FFC FPC Adapter Board. Both serve the same broad role as 4-pin FFC/FPC cable connectors; the exact layout is what separates the better match.
