SMD code R014
Marking codes are not standardised, and the same code is reused by unrelated makers for unrelated parts. Below is every part in our tables printed with it, and any printed with a code that is easy to misread as it, from the manufacturers' own marking tables and published code lists.
R014 on a chip resistor
0.014 Ω
0.014 Ω resistor
The R stands in for the decimal point, which is how sub-ohm and fractional values are printed. The same marking also reads as 14 nH on an inductor or 0.01 pF on a capacitor, and nothing in the code says which; the body of the part does.
Other readings of the same characters, most likely first
- 14 nH inductor
- 0.01 pF capacitor
Check it with a meter
Lift one end and measure across it. A good one reads 0.014 Ω. Measuring it in circuit reads the parallel combination of everything around it, which is almost always lower, never higher: well above 0.014 Ω on the board is a fault. Open, or well above 0.014 Ω, means it has failed: burnt, cracked or corroded. That does not change what to fit: the marking still says 0.014 Ω. A burnt resistor usually means the part it feeds drew too much, so find that before fitting a new one.
On a transistor or diode body (USP-6B, DFN, SOT-23-5), R014 is a part code instead. Those parts are listed below.

Is it dead? One meter test per kind
Parts of the same kind are tested the same way, so each test is here once. Each part above points to its own.
Voltage regulator
Voltage, board powered, black probe on ground. Then ohms with the power off.
Working, it reads
Input pin at the supply, output pin at its rated voltage, and the enable pin high if it has one.
Dead, it reads
- Output equal to the input: the pass element has shorted. Everything after it may have taken the full input.
- Input present, enable high, no output: failed open, or holding itself off into a shorted load. Power off and measure output to ground.
- Power off, input to output near 0 Ω: shorted.
- On the board:
- An output at 0 V is often a shorted load with the regulator in current limit. Lift the output pin: if the short stays on the board, the regulator may be fine.
- Compare:
- The same regulator on another rail or another board shows the right voltages and the right resistances.
- Watch for:
- Makers put input, output and ground on different pins in the same package, so take them from this part's datasheet. Diode or ohms readings between its pins say little; check it powered.
A dead part still carries its marking. A short or an open says it has failed, not that it is a different part.
