Airspace Structure; Human Factors; Procedure
We were inside DYLIN on the PHLBO Arrival at 6;000 feet. Approach was vectoring is on downwind for 22L at EWR. Were given traffic at 10 o'clock; not sure of the distance but it was at least several miles. Traffic was a VFR Cherokee at 5;500 feet heading from our left to right. [We] had traffic on TCAS first; altitude showed 400 feet below us. Picked up traffic visually then received a 'monitor vertical speed' RA (Resolution Advisory). We were above the TCAS pitch area and in level flight so we maintained pitch and altitude. Traffic passed beneath us. ATC said traffic was 500 feet beneath us; TCAS said 400 feet. Received 'clear of conflict.' Continued to EWR. I did not notify ATC of the RA as we did not have to deviate from our clearance.
B737 Captain reported receiving a Resolution Advisory caused by VFR traffic during approach.
