比较老的晶体管在那里买?
需要两种比较老的晶体管,跑了好些地方都没有买到,这里diyer多,想请教那里能买到?国内是有,卖家不愿意麻烦寄过来。 或者请高手给查查,用什么可以替换这两种管子. J585, K2508 谢谢 |

K2508有2种,2SK2508 or RJK2508DPK
去digikey.ca看看,没有也容易找代换的。 J585 Transistor Datasheet. Parameters and Characteristics.

是否确定是楼上说的2个型号?但不象是模拟电路用的。http://www.digikey.ca/product-search...K2508+&x=0&y=0 SAYAL是没有的,DIGIKEY应该能找到代替品。一般来说,现在的管比以前的好多了。 |

可以肯定是上面2个型号了。我找了DIGIKEY,N-CH的有可能的代替品:http://www.digikey.ca/product-detail...5FS-ND/1056776 P-CH的,最大电流只有6A的,差一点,勉强能用:http://www.digikey.ca/product-detail...5FS-ND/1055645 |

在Digikey上帮你找了两个替换
FQP9P25:可以替换2SJ585LS http://www.digikey.ca/product-detail...5FS-ND/1055385 STP17NF25: 可以替换2SK2508 http://www.digikey.ca/scripts/DkSear...1-5-nd&x=0&y=0 你定的管子如果不到200加元,需要付8元的shipping fee。用信用卡付账后,第二天能送到你家。 这两个管子都是MOSFET开关管,不是模拟应用的。 |
