Parts to order for prototyping

I have a vaguely similar spreadsheet too, and using that I’ve extracted a sort of kind of list of the parts I have used most often (mainly for assembling, as well as for prototyping), for what it is worth, which is not much:

# Part
255 Resistor 100k
236 Resistor 1k
233 Jack 1/4" vertical
216 Capacitor 100nF ceramic disk
164 Resistor 10k
135 Diode 1N5817
101 Capacitor 10µF electrolytic
82 Molex Crimp terminal
78 Molex Connector 2 pin
75 Diode 1N4148
74 Molex Header 2 pin
72 Header 10 pin shrouded
69 Resistor 47k
63 DIP socket 14 pin
54 Transistor 2N3904 TO-92
54 Op amp TL074 DIP
49 DIP socket 8 pin
46 Resistor 22k
45 Resistor 1M
43 Knob MF-A01 6.35 mm
38 Resistor 20k
35 Potentiometer B100k 16mm dia, panel mount, 6 mm shaft
35 Op amp TL072 DIP
31 Resistor 10k 1/8 W metal film
31 Toggle switch SPDT panel ON-ON
31 Knob MF-A01 6 mm
30 Resistor 1.8k
30 Resistor 2k
30 Resistor 2.2k
27 Resistor 470R
27 Resistor 4.7k
26 Capacitor 100nF 0805
26 Resistor 100k 0805
26 MF-A03 knob 6 mm
25 Resistor 220R
25 Resistor 30k
23 Transistor BC547 TO-92
21 Diode 1N4004
21 Potentiometer B100k 9mm dia, PCB mount vertical, 6.35 mm shaft
20 Capacitor 1nF polyester
20 Capacitor 10 nF polyester
20 LED green 5 mm

Except where noted:

  • Everything is through hole
  • Resistors are 1% metal film 1/4 watt

As for why I list four more Molex connectors than headers, good question.
