Tube cross-reference
D2C alternatives, equivalents, and replacements
Review exact electrical variations and directional substitutions recorded for the D2C voltage - triode (single high frequency). Compare core specifications and verify every restriction before using a replacement.
Replacement tubes for D2C
The following tubes are recorded as possible replacements for D2C. This direction does not establish that D2C can replace them.
Power - Triode Single (under 10W)
The database records 958A as a possible replacement forD2C.
No special restrictions are recorded for this substitution.
| Specification | Original tube | Replacement |
|---|---|---|
| Tube type | Voltage - Triode (single high frequency) | Power - Triode Single (under 10W) |
| Construction | Triode | Triode |
| Base | Not recorded | 5BD |
| Socket | Not recorded | ACORN5 |
| Base pins | Not recorded | 5 |
| Sections | 1 | 1 |
| Heater voltage | 1.25 V | 1.25 V |
| Heater current | 0.1 A | 0.1 A |
Where D2C can be used as the replacement
In these recorded relationships, D2C is the replacement tube. The listed original tubes are not automatically suitable as replacements for D2C.
Power - Triode Single (under 10W)
The database records D2C as a possible replacement for958A.
No special restrictions are recorded for this substitution.
| Specification | D2C replacement | Original tube |
|---|---|---|
| Tube type | Voltage - Triode (single high frequency) | Power - Triode Single (under 10W) |
| Construction | Triode | Triode |
| Base | Not recorded | 5BD |
| Socket | Not recorded | ACORN5 |
| Base pins | Not recorded | 5 |
| Sections | 1 | 1 |
| Heater voltage | 1.25 V | 1.25 V |
| Heater current | 0.1 A | 0.1 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.
