Is there a pin-compatible replacement for VHF160808H3N9ST?

Yes, several candidates like SDCL1608C3N9STDF share the 0603 package and 2-pin layout. While they are form-fit compatible, true pin-to-pin replacement requires verifying the full electrical performance in your circuit.

What risks should I check before replacing VHF160808H3N9ST?

Before replacing, verify the substitute's DC Resistance (DCR), as higher values can reduce efficiency. Also, check the Q-factor vs. frequency and Self-Resonant Frequency (SRF) from the datasheet to ensure performance in your specific RF application.
