Need help with my project.

I ran into some problems fixing my brother's konked out instrument cluster.
There are some bad components that i have identified. But my search on google has been limited at best.
Component Position Component Code
TR5 C458 D 3J3
TR7 C141 E S 2
DA1 P209 S X
R10 2w 20ΩJ 3N3


I found out that;
DA1 is DAP209 from Rohm
TR5 might be 2SC458 from hitachi

Am i right ? Does any one know what about the others ?
here are some of the links to pics of the board.

**broken link removed**


Thanks Guys

TR5 will be a 2SC458, and TR7 a 2SC141, you already know DA1, and R10 is clearly labelled as a 20 ohm 2W resistor.

What does the J stand for after the ohm value of the resister ?

Thanks for the help, Nigel

ps; this is a little out of topic but is there anything i can spray onto the board to help it withstand age and corrosion?

No idea?, but not anything worth bothering about!.

resistor, not "resister"

Probably the maximum tolerance for the resistor values?

yeah , i know. typed it out too fast with out a spell check

J = 5% tolerance

They also have K for 10%,
some people wronly think you multiply the printed value by 1000


B = ±0.1pF
C = ±0.25pF
D = ±0.5pF, ± 0.5%
E = ±0.25%,
F = ±1pF, ±1%, Brown
G = ±2pF, ±2%, Red.
H = ±2.5%
J = ±5%, Gold.
K = ±10%, Silver.
L = ±15%
M = ±20%, (no color band on resistors),black
N = ±30%
P = +100% / - 0%
R = + 30% / -20%
S = + 50% / -20%
W= +200% / - 0%
X = + 40% / -20%
Z = + 80% / -20%

Sweeet thanks alot guys
