-Smaller value capacitors (i.e. usually under 1 uF) generally have no polarity. ​ Anything above 1 uF is typically an electrolytic capacitor, and it will have a polarity marking. ​ Most often the "​-"​ side is marked with a big stripe, although sometimes it's the "​+"​ side that is marked. ​ (Strangely, the "​+"​ side seems to be marked on capacitors made in U.S.A.)+**Smaller value capacitors (i.e. usually under 1 uF) generally have no polarity**.  ​**Anything above 1 uF is typically an electrolytic capacitor, and it will have a polarity marking**.  Most often the "​-"​ side is marked with a big stripe, although sometimes it's the "​+"​ side that is marked. ​ (Strangely, the "​+"​ side seems to be marked on capacitors made in U.S.A.)

 Most other components have some sort of mark as to their correct orientation. ​ IC's will have a dot, transistors have a flat side, LEDs have a flat side (and the two leads will be different lengths).  ​ Most other components have some sort of mark as to their correct orientation. ​ IC's will have a dot, transistors have a flat side, LEDs have a flat side (and the two leads will be different lengths).  ​

 When in doubt, don't hesitate to contact the distributor for clarification.

 Yes, 1N4004 is a replacement for 1N4002, it's just a type for higher Voltages (100V for 1N4002 vs. 400V for 1N4004).
