Transistor sub
"Kevin Dooks" wrote in message
... Hi, I am in need of a suitable replacement for a 2SC1307 rf transistor and was wondering if anyone had any suggestions. The 2SC2098 looks like a possibility as does the MRF475 both of which are about as old as the 1307 and equally if not more difficult (and expensive) to obtain. Or would I be further ahead trying an ERF2030 and associated components as some use to replace the 2SC1969 and 2SC2166. TIA Kevin Consolidated Electronics web catalog indicated they have the 2SC1307 in stock @ $7.95 USD. http://www.ceitron.com/semi/semi.phtml?part=2SC1307+ -- Dave M MasonDG44 at comcast dot net (Just substitute the appropriate characters in the address) Life is like a roll of toilet paper; the closer it gets to the end, the faster it goes. |

put finger to keyboard and composed: Hi, I am in need of a suitable replacement for a 2SC1307 rf transistor and was wondering if anyone had any suggestions.

Or would I be further ahead trying an ERF2030 and associated components as some use to replace the 2SC1969 and 2SC2166. TIA Kevin My vrt databook lists the specs as ... 2SC1307 HF-L, 70V, 8A(ss), PQ = 15W (50MHz) ss = peak value 2SC2098 AM-L, 70V, 6A, PQ = 15W (28MHz) MRF475 AM/SSB-L 48V, 4A, PEP = 12W (30MHz) 2SC1969 AM-L, 60V, 6A, PQ = 16W (27MHz) 2SC2166 HF-L, 75V, 4A), PQ 6W (27MHz) All of your replacement options appear to be inferior (I couldn't find the ERF2030). I found this transistor: 2SC2050 AM-L, 60V, 6A, PQ 13W (50MHz) FWIW, the 2SC1307 is listed as its sub, but not vice versa. BTW I can get a 2SC1307 for AU$10.45 in Australia, assuming it is not a fake. - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |
