Tube cross-reference
E86C alternatives, equivalents, and replacements
Review exact electrical variations and directional substitutions recorded for the E86C voltage - triode (single high frequency). Compare core specifications and verify every restriction before using a replacement.
Exact variations of E86C
These designations belong to the same electrical variation group. Their names may differ because of international standards, manufacturing tolerances, or materials, but they are recorded as electrically equivalent—not merely substitutes.

Where E86C can be used as the replacement
In these recorded relationships, E86C is the replacement tube. The listed original tubes are not automatically suitable as replacements for E86C.
Voltage - Triode (single high frequency)
The database records E86C as a possible replacement for6CM4.
- Parallel heater circuits only
| Specification | E86C replacement | Original tube |

| Sections | 1 | 1 |
| Heater voltage | 6.3 V | 6.3 V |
| Heater current | 0.165 A | 0.17 A |
Verify before substituting
Matching a base or heater voltage is not enough to prove that two tubes are interchangeable. Check pin connections, heater current, maximum ratings, bias requirements, warm-up behavior, and the equipment manufacturer’s service documentation before making a substitution.
