A study was conducted on the effects of compositional modifications on the temperature coefficient of resonance frequency (TCF) in the disc planar vibration mode for the bismuth layer-structured compound SrBi2Nb2O9 (SBN)-based ceramics. The substitution of the strontium site by divalent and trivalent ions improved the TCF, accompanying the relaxation of elastic anomaly. The tolerance factor, $t$, was calculated for a pseudo cubic block to study the contribution of the structural factor to Curie temperature, $T_{\text{C}}$, and the temperature of elastic anomaly, $T_{\text{ea}}$, for each sample. $T_{\text{ea}}$ showed no apparent tendency with $t$, whereas $T_{\text{C}}$ increased as $t$ decreased.
