Is there a pin-compatible replacement for MPX334K31C3KN15600?

Yes, parts like MPX224K31C3KN15600 are pin-compatible (same package and lead pitch), but they are not electrically identical due to different capacitance values.

What risks should I check before replacing MPX334K31C3KN15600?

Before replacing, verify that a lower capacitance (0.22µF vs 0.33µF) is acceptable for your EMI filtering needs. Also confirm the substitute meets all required safety certifications for your region.
