We just began descending on the PHIBO arrival into Newark. Washington ARTCC had given us a crossing restriction of FL270 at FUBAR as per the charted procedures. About one minute later we get a frequency change to a new Washington ARTCC. After the captain checked in; we were instructed to descend via the PHIBO arrival into Newark. The first officer reached up and selected the next hard altitude of 11;000 feet at SUMTO. The first officer did this before crossing FUBAR. The captain verified 11000 feet selected. About 30 seconds before crossing FUBAR the captain then stated we still need to cross FUBAR at FL270. The first officer reached up and manually TCS (Touch Control Steering) the aircraft to level flight and reselected FL270 recapturing the altitude. We descended approximately 150 feet below altitude when crossing FUBAR.
Air carrier First Officer reported missing a crossing restriction due to premature selection of the next hard altitiude.
