A heat-not-burn (HNB) aerosol-generating device may include a capsule and a device body. The capsule may include an aerosol-forming substrate and a conductive component. The conductive component may include a first end section, an intermediate section, and a second end section. The intermediate section may be configured to heat the aerosol-forming substrate. The first end section and the second end section may each have at least one surface discontinuity. The device body may include connector pins configured to engage with the at least one surface discontinuity of each of the first end section and the second end section of the conductive component so as to establish an electrical connection with the capsule.
