Product details

The 2FA1-NASP-PCB-3: It is the right-angle through-hole variant of the 2FA1 series, intended for board-edge mounting where the connector body runs parallel to the PCB. The locking ramp fastening is the Fakra-specific feature that prevents the plug from vibrating loose in automotive or industrial environments — a key difference from standard SMB push-on connectors. Code A keying (blue/water housing color) ensures this plug mates only with a matching Code A Fakra receptacle, preventing cross-mating in multi-connector harness assemblies.

Rated at 50 Ohm impedance and 3 GHz maximum frequency, this plug covers GPS /L2, cellular (up to 3G), and ISM band applications. The 3 GHz ceiling is the practical limit for the SMB interface with the Fakra locking ramp — above that, the insertion loss and return loss degrade beyond what most system budgets allow.

Mounting and Termination for the Board Builder

Through-hole right-angle mounting means the four PCB legs and the center pin solder into plated through-holes — no press-fit tooling required. The zinc die-cast body with tin finish gives a solderable ground plane connection and meets the corrosion resistance expected in automotive RF harnesses.

Frequently asked questions

Where can I buy 2FA1-NASP-PCB-3?

2FA1-NASP-PCB-3 is sourced to order through independent distribution.

Is 2FA1-NASP-PCB-3 compatible with other FAKRA connectors?

Yes, but only with Code A Fakra receptacles. The Code A keying (blue/water housing) and locking ramp ensure it mates exclusively with the matching Code A female jack. It will not physically mate with Code B, C, D, or other keying variants — the ramp geometry and housing color prevent cross-mating. The RF interface is standard 50 Ohm SMB, so signal compatibility is maintained when mated with the correct Code A counterpart.

Does 2FA1-NASP-PCB-3 require a specific crimp tool?

No crimp tool is needed. No crimp terminal or separate ferrule is involved. For the mating receptacle side (female jack), a crimp tool may be required depending on the cable assembly chosen, but for this plug itself, soldering is the only termination method.
