Di beberapa standar simbol-simbol ini dapat berbeda dan bervariasi, demikian juga dengan notasi (kode) singkatan untuk menjelaskan sebuah komponen seperti: Transistor (Q, Tr, atau T), Relay (Re, Ry, atau K), Integrated Circuit (IC atau U).
Apabila dalam sebuah sistem rangkaian listrik atau rangkaian elektronik terdapat lebih dari satu komponen yang sama, maka dibelakang notasi singkatan tersebut ditambah angka misalnya U1, U2, U3, R1, R2, R2, C1, C2, C3, dan seterusnya.
