Cyrillic designation: 6Н1П-ЕВ. The -ЕВ suffix indicates extended military grade with enhanced vibration, shock, and temperature ratings.
Electrically identical to the standard 6N1P but with tighter tolerances, longer rated life (5000+ hours), and wider operating temperature range.
Pin-compatible drop-in replacement for 6N1P in any application.
Soviet foreign_substitutes.json lists 6N1P-EV as a substitute for ECC802S (premium 12AU7) — this is approximate only, the electrical characteristics differ significantly.
