Is there a pin-compatible replacement for HG1V337M1012PC?

No pin-compatible replacement with identical key parameters was identified in this review. Candidates with a matching radial package, like NPHC1101V221MJTM, have different electrical values (lower capacitance) that must be reviewed by an engineer.

What risks should I check before replacing HG1V337M1012PC?

The primary risks are package and electrical mismatches. A surface-mount (SMD) part cannot replace a through-hole (Radial) part without a new PCB. Using a capacitor with lower voltage is unsafe, and incorrect capacitance can cause circuit instability or failure. Always verify datasheet parameters before substituting.
