DO-201 axial package, through-hole mounting
Housed in the DO-201AA (DO-27) axial-lead package, the 1.5KE12H is a through-hole device intended for point-to-point or PCB mounting. The DO-201 body diameter and lead spacing are standard across the 1.5KE series, so the PCB footprint is shared with other voltage variants in the family. The axial lead form factor suits high-reliability layouts where a conformal coating or potting compound is applied after assembly — the lead-to-body seal is robust against solvent ingress during cleaning cycles.
Active production, no second-source on record
No official second-source or pin-compatible alternative is listed in the available records — the BOM position is single-sourced to this order code.
