Frequency Tolerance: ±20ppm (exact match required)
Load Capacitance: 30pF (exact match required)
ESR: 100 Ohms (exact match required)
Operating Mode: Fundamental (exact match required)
Operating Temperature Range: -10°C to 60°C (exact match required)
Package / Case: HC-49/U (exact match required)
Mounting Type: Through Hole (exact match required)
Physical Dimensions: 0.435" L x 0.183" W; Height 0.530" max (exact match required)

The IQD Frequency Products LFXTAL003134BULK satisfies all substitution criteria and is classified as a parametric equivalent. Both parts are active products with RoHS3 compliance and identical electrical and mechanical specifications.
