Product details

0.50 mm pitch, 40-position ZIF — what this FFC connector fits

The 4-1734742-0 is a 0.50 mm pitch, 40-position FFC/FPC connector from TE Connectivity's 1734742 series, designed for vertical SMT mounting with a slide-lock ZIF mechanism.

ZIF slide lock and solder retention — field-service angles

The slide-lock ZIF mechanism means the FPC inserts without force and locks with a simple slide — no tools needed for field replacement or rework. Solder retention pads on the SMT footprint add mechanical hold during reflow and resist vibration shear, a practical benefit for the board layout engineer.

Packaged in Tape & Reel (TR) for automated pick-and-place, with Cut Tape (CT) available for prototype or low-volume builds.

Frequently asked questions

What is the pitch of the 4-1734742-0 connector?

The pitch is 0.020" (0.50 mm), the tightest common FPC pitch, which drives the PCB footprint and routing density.

Is the TE 4-1734742-0 RoHS compliant?

Yes, it is ROHS3 compliant.

Does the 4-1734742-0 have a ZIF mechanism?

Yes, it uses a slide-lock ZIF mechanism for tool-less FPC insertion and retention.
