Substitute Part Grouping Explanation

Substitution eligibility for the TC-62.500MBD-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Frequency: 62.5 MHz
Output Type: CMOS
Supply Voltage: 3.3V
Function: Enable/Disable
Package Type: 4-SMD, No Lead
Package Dimensions: 3.20mm x 2.50mm
Operating Temperature Range: -40°C ~ 85°C
Frequency Stability: ±25ppm

The 7X-62.500MBD-T meets all mandatory matching parameters. The primary difference between the main part and substitute is the base resonator technology (MEMS versus Crystal) and maximum supply current specification. Both components deliver identical electrical performance at the system interface level and are pin-compatible within the specified package footprint.
