Substitute Part Grouping Explanation

Substitution eligibility for the ASEMPC-20.000MHZ-T3 is determined by the following critical parameters:

  • Frequency: 20 MHz (exact match required)
  • Output Type: CMOS (exact match required)
  • Supply Voltage Range: 2.25V ~ 3.6V (exact match required)
  • Function: Enable/Disable (exact match required)
  • Package / Case: 6-SMD, No Lead (exact match required)
  • Mounting Type: Surface Mount (exact match required)
  • Physical Dimensions: 0.126" L x 0.098" W, 0.035" max height (exact match required)
  • Base Resonator: MEMS (exact match required)
  • Series: ASEMP Pure Silicon™ (exact match required)

The ASEMPC-20.000MHZ-LR-T qualifies as a substitute part because it maintains all critical electrical and mechanical parameters while offering enhanced frequency stability and extended operating temperature range.
