Product details

640445-9: MTA-156 9-Position Header with Friction Lock

Board Fit: Pitch, Pin Length, and Mounting

Through-hole solder termination with a contact length - post of 0.125" (3.18mm) — this is the depth the pin extends below the PCB surface after soldering. The natural (white) thermoplastic, glass-filled housing is UL94 V-0 rated.

Peer Comparison: 1-292164-1 vs 640445-9

The 1-292164-1 is a different connector entirely — it is an 11-position, 2.00mm pitch header from the CT series, with a 4-wall shroud and a detent lock. The 640445-9 runs at 3.96mm pitch and carries a friction lock. These are not form-fit-function equivalents: the pitch and position count differ, so a board spin would be required to swap.

Frequently asked questions

What is the pitch of the 640445-9?

The pitch is 0.156" (3.96mm). This sets the hole spacing on the PCB for the through-hole pins.

Is the 640445-9 shrouded?

Yes, it is shrouded on one wall (shrouded - 1 wall). This provides partial pin protection and guides the mating receptacle during insertion.

Does the 640445-9 have a friction lock?

Yes, it uses a friction lock to secure the mated connector pair, providing vibration resistance in industrial harness applications.

Is the 640445-9 RoHS compliant?

Yes, it is RoHS compliant.
