in my traffic light project i need 1N4148 in its circuit but i can n't get it so is there an problem if i replace it with 1N4007 or they don't have the same function

If you cannot post at least part of your schematic, it's hard to help.

Can you scan the PDF and convert it to some type of image file (JPG or PNG)?

The 1N914 switching diode is extremely similar to the 1N4148; so much so that they are generally interchangeable.

If the circuit in question will operate at low frequency, and if you have the room, then you can probably use a 1N400x series diode instead. If the circuit depends on fast recovery times, you should look at another diode.

Schottky diodes like the 1N5817 have extremely low recovery times.
