28-Pin Right-Angle FFC/FPC Board vs 4-Pin Bent-Pin Adapter: Choose the Fit

Choose between these uxcell FFC/FPC adapter boards by matching pin count, socket-side pitch, board dimensions, and header format-not by treating them as interchangeable cable connectors.

Last updated Aug 17, 2026

Choosing an FFC/FPC adapter board comes down to a strict fit question: does the pin count, pitch arrangement, and header format match the connection you need? These two uxcell cable connectors address different layouts, so the useful choice is the one that aligns with your required interface. Their listed prices are $4.66 apart.

Quick verdict

Pick the FFC FPC Connector Board 28 Pins Double Row Right Angle Pin Header Adapter for a larger-pin-count FFC/FPC connection with the named right-angle header format. Choose the 4Pin 1.0 to 2.54 mm Double Row of Bent Pins Pull-down FFC FPC Adapter Board when your project calls for its four-pin, bent-pin pull-down arrangement.

Both are new uxcell cable connectors intended for FFC/FPC connections. The deciding details are the exact electrical layout and physical board format, rather than a broad feature advantage.

Compact comparison

Adapter board	Listed configuration	Pitch and overall size	Listed price
FFC FPC Connector Board 28 Pins Double Row Right Angle Pin Header Adapter	28 pins; double row	0.5 mm FPC socket side; 1.0 mm FPC back side; 2.54 mm DIP; 33 x 40 mm	$19.50
4Pin 1.0 to 2.54 mm Double Row of Bent Pins Pull-down FFC FPC Adapter Board	4 pins; double row	1.0 mm FPC socket side; 0.5 mm FPC back side; 2.54 mm DIP; 32 x 17.5 mm	$14.84

Where each board wins

Choose the 28-pin right-angle board when a 0.5 mm FPC socket-side pitch is the required interface. Its listed 1.0 mm back-side pitch and 2.54 mm DIP pitch define a specific FFC/FPC-to-DIP arrangement.
Choose the 4-pin bent-pin board when a 1.0 mm FPC socket-side pitch matches the connection you are adapting. Its 0.5 mm back-side pitch and 2.54 mm DIP pitch establish a different pitch relationship from the 28-pin board.

Product notes

FFC FPC Connector Board 28 Pins Double Row Right Angle Pin Header Adapter

This board is the more targeted choice for a planned 28-pin FFC/FPC connection. Its listed 33 x 40 mm overall dimensions give it a distinctly larger board format than the four-pin alternative, while the description identifies a double-sided PCB-support design with a single flat-cable socket. Choose it when that larger connection count and board format are part of the design requirement, rather than simply selecting by category. The limitation is equally specific: its 28-pin configuration is designed around that connection count, so it is not the direct match for a four-pin interface. The right-angle pin header named in the title is the key format cue for the final selection.

4Pin 1.0 to 2.54 mm Double Row of Bent Pins Pull-down FFC FPC Adapter Board

The four-pin adapter is the focused option for a compact, low-pin-count FFC/FPC connection. Its listed 32 x 17.5 mm dimensions make it the smaller board format in this comparison, and the title calls out double-row bent pins with a pull-down arrangement. Choose it when those physical format terms align with the connection you are building around. The stated four-pin configuration is also its limitation: it is purpose-built for a four-pin interface rather than a higher-pin-count connection. For shoppers comparing only the listed prices, this board is the lower-priced choice at $14.84, while its fit still depends on the required pin and pitch layout.

Final choice by use case

Select the FFC FPC Connector Board 28 Pins Double Row Right Angle Pin Header Adapter when your build calls for a right-angle header and the larger 28-pin format. Select the 4Pin 1.0 to 2.54 mm Double Row of Bent Pins Pull-down FFC FPC Adapter Board when a four-pin bent-pin pull-down adapter is the required format. In short, treat the listed connector geometry and pin count as the deciding factors; the price difference is secondary to getting the interface right.
