LM348 substitute

(OP)
If we replace LM348 Op-Amp with TL074 Op-Amp, this is a direct substitute, and no changes are needed in passive components in circuit?

RE: LM348 substitute

Hypothetically, yes. But without a detailed analysis of what each op amp is doing in the circuit, it's not really possible to say

RE: LM348 substitute

(OP)
Two LM348 op-amps in this circuit. So is it OK?

RE: LM348 substitute

Why are you looking to replace he LM348? Your circuit seems rather basic, but layout issues may lead to oscillation or crosstalk if you use ICs with higher bandwidth. Instead of a TL074, what about an LF444? It is designed to replace the LM348, with similar characteristics but with a reduced power consumption.
