0.3mm FPC FFC Cables, Sockets & Extension Boards
0.3mm FPC/FFC cables, PCB sockets and extension boards
This collection contains ultra-fine 0.3mm-pitch flat-flex interconnect parts: A-type and B-type FFC cables, flip-cover bottom-contact PCB sockets, and extension boards for joining compatible cables. Pitch, contact count, contact orientation and connector geometry must all match; 0.3mm parts are not interchangeable with 0.5mm or 1.0mm FPC/FFC products.
Products in this collection
- 0.3mm FFC cables: two broad cable listings with A-type and B-type contact orientations.
- Contact counts: cable variants span multiple counts from 7P upward, including selected even and odd counts; availability varies by listing and length.
- Cable lengths: listed options include 60mm, 100mm, 120mm, 150mm, 200mm and 300mm, depending on the product and contact count.
- PCB sockets: 5-piece flip-cover, bottom-contact 0.3mm connectors in selected 11P–61P counts.
- Extension boards: 0.3mm cable couplers in 23P, 25P, 31P, 35P, 39P, 45P, 51P and 61P options.
How to select a 0.3mm FPC/FFC part
- Verify the pitch: measure center-to-center contact spacing with suitable magnification. Do not estimate pitch from cable width alone.
- Count every contact: match the exact pin count shown on the existing cable, socket drawing or PCB footprint.
- Check A or B orientation: A-type cables commonly expose contacts on the same side at both ends, while B-type cables expose them on opposite sides. Confirm the seller diagram and your assembly orientation.
- Match contact side: the sockets here are described as bottom-contact. An upper-contact connector with the same pitch and pin count is not an automatic substitute.
- Confirm dimensions: compare cable thickness, exposed-contact length, stiffener dimensions, socket height, mounting tabs, pad layout and insertion direction.
- Select the required length: allow routing clearance without sharp folds, abrasion or stress at the termination.
Cables, sockets and extension boards compared
A cable carries conductors between two compatible terminations. A PCB socket locks the cable to a board footprint. An extension board mechanically joins two matching cables. These products do not convert voltage, rearrange pinouts or translate signal protocols.
Compatibility boundaries
Matching 0.3mm pitch and pin count does not by itself prove compatibility. Contact orientation, cable thickness, exposed-contact geometry, connector contact side and device pinout can still differ. References to LCD or LVDS in individual product titles describe possible use contexts, not universal compatibility with displays, cameras, OLED modules, laptops or other equipment.
No collection-wide claim is made for 4K bandwidth, MIPI or LVDS signal integrity, medical or aerospace use. High-speed interfaces may require controlled impedance, shielding, grounding and length limits that a generic cable or extension board does not establish.
Ratings and materials
Do not apply one voltage, current, temperature, conductor material, insulation material or certification to every item in this collection. Confirm electrical ratings, construction and compliance documentation for the exact product and variant before production use.
Frequently asked questions
Can a 0.3mm cable fit a 0.5mm socket?
No. Their contact spacing and cable dimensions differ.
Are A-type and B-type cables interchangeable?
Usually not. Their end-contact orientation differs and can reverse the required mating geometry.
Can I choose a replacement using only pin count and length?
No. Also verify pitch, contact orientation, cable thickness, exposed-contact dimensions and pinout.
Does the extension board convert the signal?
No. It is a passive interconnect and does not convert protocol, voltage or pin assignment.
Are the sockets compatible with every 0.3mm cable?
No. Match the pin count plus cable thickness, contact side, insertion geometry and exposed-contact length.
