Board Layout and Routing Fit
The 647676-9: This is a single-row, 9-position header on a 3.96mm pitch — the board footprint is straightforward: one row of 9 plated through-holes spaced 0.156" apart. That keeps the cable harness running along the board plane, useful in enclosures where z-height above the PCB is tight.
Current and Voltage Capability
Rated 7.5 A per circuit at 250VAC — this is the maximum continuous current per pin at 25°C ambient. For higher ambient temperatures, derate per the manufacturer's curve.
This is not a secondary lock (TPA), but the friction lock is sufficient for applications where the connector pair is not subject to high shock or continuous flex. Mates with the corresponding Economy Power receptacle housing (e.g., 1-480318-0 series) using the standard crimp terminals. The 1-wall shrouding guides the plug during mating and protects the pins from incidental contact.
Cross-Shop Alternatives
If 647676-9 is unavailable, consider TE 4-1775099-7 (same 9-position, 3.96mm pitch, right-angle, friction lock) or 1376366-8 (8-position variant). The 1-292164-1 is a 9-position vertical header from the same series — same pitch and current rating but straight through-hole, not right-angle. Confirm the mating receptacle compatibility before substituting.
