I needed 2N3904 transistors so I went to the few crappy electronics shops we find in my country. They didn't have those, but they gave me 2N9013 and stated that those were equivalent NPN transistors. Both in TO-92 packages.

I've searched for a datasheet and found one from Promax-Johnton (who?) with "1W OUTPUT AMPLIFIER OF POTABLE RADIOS IN CLASS B PUSH-PULL OPERATION" which is worst than Chinese to me :(

My questions are: 
1. Is if this part is a good replacement for my 2n3904? 
2. What additional considerations I need to be aware? 
3. Recommendations?

Thanks in advance.


Question: Preventing a specific CSS file from getting loaded in Yii
Answer: You can use the scriptMap property of CClientScript in your specific view, passing false for the particular script/css file's key that you don't want to be rendered. From the doc:


  The array keys are script file names (without directory part) and the array values are the corresponding URLs. If an array value is false, the corresponding script file will not be rendered.


For example, in say views/site/pages/about.php:

Yii::app()-&gt;clientScript-&gt;scriptMap = array(
    'main.css' =&gt; false
);


to disable the inclusion of main.css registered with registerCssFile.

The scriptMap can also be used for controlling the rendering of js script files.
