Help identifying ceramic resonator

I have a ceramic resonator in a remote that has broken leads. The numbers on the case are: 1422 on the first line, 271-4 on the second line and the initials C.P. on the third line. I can't find it in the Digi-Key catalog and I can't determine the resonate frequency. The remote is from a GE TV. Any help is appreciated.

Thanks, Charles

This is a preparatory part number for the remote. GE does not support servicing these remotes.

What you can do is go to any of the local electronics parts suppliers that sell generic TV and electronics service parts, and ask about a universal type ceramic crystal for remote controls. In most of the remotes these are a

455 kHz ceramic crystal. I cannot remember if it is a series are parallel resonant device in these remotes. I suspect it is a series type. These remote control crystals should sell for about $2 to $5 on the average.

Another thing you can do is go to any of the local flea-markets, and look for some of the vendors that sell old remotes. Get a number of cheap ones, and take them apart. In each one, you will get a good IR LED, and the ceramic crystal as well, unless by coincidence they are defective. These two parts are very common in many of these remotes.

The most common failures in these remotes is the ceramic crystal, and the IR LED. The crystal is usually damaged when the remote is dropped very strongly.

I just went through this about 2 weeks ago. My RCA remote (CRK39K a.k.a 173916) was dropped and stopped working. It had the same ceramic resonator. My resonator 1422 271-4 was made by Murata. Even after 26 years, they won't disclose any information about the resonator due to an NDA... Anyway, I found a schematic for my TV which also lists the remote control parts. It clearly states that the part is a "crystal", mfgr part number 151804, and that the frequency is 455KHz.

I bought a Murata CSBLA455KJ58-B0 from Mouser for $0.81 plus shipping. Note: I splurged on the sealed/washable version. The non-washable version is p/n CSBLA455KEC8-B0 and is $0.56. Digikey has the "E" verson for $0.61. If you really want an exact replacement, you can get the 151804 from VanceBaldwin.com for $5.90 plus shipping. (Do a search for part number 271-4).

The leads don't quite extend past the circuit board with the resonator laying down on the foam pad, but you can still get good quality solder joints. My remote is back together and working great!

Good luck!

Thanks, I had concluded that it was a 455KHz resonator and have just ordered one from DigiKey.

Thanks, Charles
