The number consists of 5 elements, ELEMENT 1 This number indicates the number of active internal or external connections minus one. ELEMENT 2 Originally indicated that this device was registered with EIAJ, although now it is not the case. ELEMENT 3 Polarity and applications. A - PNP High Frequency B - PNP Low Frequency C - NPN High Frequency D - NPN Low Frequency J - P Channel F E T K - N Channel F E T ELEMENT 4 Serial number,in order of registration. ELEMENT 5 Suffixes indicate improvements and their sequence. A = First improvement B = Second improvement,etc NOTE: An improved version will replace an unimproved type in all cases, but an unimproved version will not always replace an improved type. NON JAPANESE TRANSISTORS Many manufacturers in Korea, Taiwan, etc., have adopted similar numbers to the Japanese and change the prefix eg KSC945. To make things more confusing,the KS is left off the device therefore C945 is the only marking on the transistor. In most cases the specs are similar but pin outs are not. Please check circuit prior to replacing the transistor, the same number does not always mean that pin outs are the same. TRANSISTOR SUBSTITUTIONS WES Components reserves the right to supply a substitution transistor where the original is not available or is out of stock. These substitutions will be ones confirmed as close to original as to be a direct replacement. A transistor substitution manual is also available which lists possible substitutions for you to substitute devices not listed or are NLA. The comparison is on similar specs only. Therefore this should be read in conjunction with the Transistor Manual to ensure that cases and pin-outs are the same and that the transistor with the best specs is chosen.
