Cross-reference check

Relationships and limits.

  • The row explicitly names HE15185-4SN1 as the number replaced for spares.
  • The IPC prints one unit at this item; separate fleet tracking for No. 1 and No. 2 positions does not change the catalog part number.
Important limit

The catalog establishes a one-way replacement statement from HE15185-4SN1 to 211C223-647. It does not prove reverse interchangeability or provide the switch pressure setting.
