Electronics Spare Parts
Sometimes, finding electronics spare parts is not easy. To identify the part number is one problem and to get the spare parts is another question. Take a look at the photo below, which one is the part number? This is a power IC and was found in one of the HP Deskjet power board. Usually we do not repair inkjet/deskjet but because this was a friend request so we just help him to repair it. I have found the cause of the problem in the power IC but then again which one is the part number? The top one (j10429) or the bottom number 5573 as seen from the photo below?
After careful research I concluded that the bottom one was the part number. The actual part number is FA5573 and the manufacturer again did not put in the word "FA" which made us hard to find the actual part number. Is it difficult for the manufacturer to just print the word "FA" onto the IC? How do I know that the FA5573 is the actual part number? First, i could not find the j10429 datasheet and next was the FA series which I had came across before ie FA5301, FA5302 and etc. So when I key in the FA5573 with the word datasheet followed behind I got the datasheet. When I looked at the datasheet pins it matched all the pinout of the IC in the power supply circuit board.
My first mission was done and the second one was to find where i could buy the electronics spare parts. I have searched from many websites and not even one that have this part number. They have the part number that was quite close but you know when replacing power IC the best is to use back the original part number. Just to ask if any one the readers in this blog have any source for this part?

HI JESTINE
the manufacturer do not care about repair , they think only for more sale of thier prouducts and not repair of them and also they do not care much about the gurantee of thier prouducts these days ifyou read the forums you will see that how much people have problem with them .i am sure you did

You are right Beh, just print the word "FA5573" and we will happy for it. Jestine

Hi Beh,
I went to the website and check for FA5573 but did not get any result.

I am trying to find a replacment for two ceramic capacitors the markings on each are:
1) jn222m-250~440x1 400-y187c 2) JN472m 250~ 440x1 400 y187c
I have not been able to find a match by putting the information into a search engine....and although it looks like part numbers (to me) evidently they are not because the supplier website does not recognize them.... I know that the first 2 digits are significant and the third is a multiplier...so (JN222M or JN472m) is this 2200 pf and 4700 pf at 250v.... I appreciate any guidence thanks

Hi Brian,
You are right it is 2200 pf and 4700pf with 250 v working voltage.

Hi sir Jestine, I have a question for you.I have a trouble of a machine.The principle of the machine is only to circulate the rotor about to 15000 rpm.And this machine controlled with digital circuits and have a lcd display.Now my problem is the motor is overheated win sit to peak power ex. 130 x 100= 13000 rpm and sitted only in 5 seconds.Now I was check the motor all I found is the ball baring is dislocated/damage.I change now the ball baring as this motor is brushless.But I found out when I tested it is the same problem the motor is overheated even I change now the ball baring of the motor.Now I check the circuit board I check the mechanical load.I found the short resistor became .2ohms when I tested it.But I read the color read,read,orange,gold this is 22k ohms +-5%.So I replace it with the correct value base on the color.And I check also the capacitor.All of the caps is normal.So, I tested again the machine but the same problem.The motor again became overheated when I sit to peak power.
Can you give me an idea sir how to trouble the mechanical load of this machine.The motor have a power input of 200 volts 13000 rpm.Now I suspected the positive controller IC LT780-5oc.Becaus when I tested the 400 volts caps connected to the input of the IC.There are no volts and the caps not working no current loaded when I will turn off the machine.

Hi Arnel,
I'm not familiar with motor troubleshooting. But with the electronic board, you mentioned that the resistor reads .2 ohm. For your information resistors rarely have short circuit- they are mainly increase in ohms or open circuit. Sometimes a slightly heated resistor could cause the color band to change. There is a possibility that the silver color have been changed to dull color and you thought it was orange color. In your case have you change the motor? Since you says that the motor is brushless then there could be an ESC that have problem.

The problem on the motor easily get heated up could be due to your incoming power supply voltage exceeded the operating voltage of the motor

Hi Chong,
Thanks for the input. The problem with the motor is when at its peak power and not when starting up.
