Power and interconnect
Aircraft electrical work is unforgiving of “close enough.” Open the leaf for the family you are on — circuit breakers, ring terminals, solder sleeves, heat-shrink, batteries — then search the PN or NSN. A listing is not a wiring-diagram approval.
Protection first
Thermal, magnetic, and combined breakers are not interchangeable because the panel hole looks similar. Capture manufacturer, amp rating, and lockout needs on the desk request.
Batteries, circuit breakers, connectors and plugs, terminals, splices, wire, heat-shrink, solder sleeves, relays, switches, static wicks, and related interconnect hardware. Open the leaf that matches the work card.
Thermal, magnetic, and thermal-magnetic designs are common. They are not drop-in substitutes. Use the circuit-breakers leaf and the exact manufacturer part number.
Observations may show labels such as Klixon/Sensata, TE Connectivity, E-T-A, Honeywell, and Eaton when recorded. A label is not an endorsement or a form-fit-function statement.
Start with the manufacturer part number from the illustrated parts catalog or maintenance manual. If an NSN is listed, search that next. Confirm finish, dash number, and engine or airframe applicability before opening an RFQ.
PartsPerk catalog pages show PartsPerk-owned observations only. They are not live stock, not certification, and not OEM affiliation. Exact PN/NSN identity is for sourcing review; publication and sellability require separate approval.
