Short answer. Yes. Article 122 of the Revised Penal Code expressly provides that the same penalty of reclusion temporal imposed for piracy on the high seas shall also be inflicted in the case of mutiny. Both acts carry the same punishment under the statute.

What Article 122 provides
Article 122 of the Revised Penal Code groups two distinct offenses under one provision: piracy and mutiny, both on the high seas. For piracy, the article punishes any person who attacks or seizes a vessel on the high seas, or who — not being a member of the crew or a passenger — seizes the cargo, equipment, or personal belongings of the vessel's crew or passengers. The penalty for piracy is reclusion temporal — imprisonment of twelve years and one day to twenty years. The article then states flatly that the same penalty shall be inflicted in case of mutiny on the high seas. There is no separate, lighter track for mutiny.
Piracy and mutiny are different acts — same penalty
The two offenses differ significantly in nature. Piracy is typically an act committed by outsiders — persons who board or attack a vessel to seize it or plunder its contents. Mutiny, by contrast, involves persons already on the vessel — crew members who rise against the officers in command. Despite this difference in who commits the act and against whom, the legislature placed them on equal footing for purposes of punishment. Both endanger the safety of the vessel, the crew, and the passengers, and the law treats that shared danger as justification for equal penalties.
What reclusion temporal means
Reclusion temporal is one of the principal penalties in the Revised Penal Code, covering imprisonment from twelve years and one day to twenty years. It is a serious penalty — more severe than prision mayor and below reclusion perpetua. For persons convicted of either piracy or mutiny on the high seas under Article 122, this is the baseline penalty, subject to any applicable mitigating or aggravating circumstances that the court may weigh in determining the exact duration within the range.
The high seas requirement
Both offenses under Article 122 must be committed on the high seas. This geographic element distinguishes them from similar acts committed in Philippine internal waters or territorial waters, which may fall under different provisions or different legal frameworks. The high seas are generally understood as waters beyond any nation's territorial jurisdiction. Acts of piracy or mutiny within Philippine territorial waters or in ports would be governed differently, and the applicable penalty may differ from what Article 122 provides.
