The goaltender heads to Philadelphia for a guaranteed conditional fourth-round pick in the 2018 draft and a conditional third-round pick in the 2019 draft.
Bob McKenzie of TSN gives a breakdown of the terms of the trade.
DET guaranteed no less than a 4th round for Mrazek. If PHI makes playoffs and Mrazek wins 5 games for PHI in reg season, 4th becomes a 3rd. If PHI advances to CF, and Mrazek wins six playoff games, the 3rd becomes a 2nd. If PHI re-signs him next season, DET gets PHI 3rd in 19.

Additionally, according to Craig Custance of the Athletic Detroit, the Red Wings will retain half of Mrazek’s salary.
