The 640501-2 is the 9-circuit, 3-row member of TE's MR (Miniature Rectangular) shrouded header line, rated 6 A per circuit at 250 VAC. Gold mating contacts on phosphor bronze terminals handle the current; the 4-wall shroud with latch lock resists vibration-induced disconnects in a board-to-cable/wire interface.
No peer order code with a documented cross-reference appears in the current record. Check the full MR series listing for same-position variants in different orientations or plating grades, or submit an RFQ with the base product number 640501 to surface available alternatives.
Board to Cable/Wire — it is a male header designed to mount on the board side and mate with a cable-side IDC or crimp receptacle housing.
