Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ASDMPC-25.000MHZ-LR-T3 are identified based on strict equivalence across the following critical parameters:

Frequency matching at 25 MHz ensures compatible timing for target applications. Output type (CMOS) must remain consistent for signal integrity and interface compatibility. Supply voltage range (2.25V ~ 3.6V) defines operational envelope compatibility. Frequency stability (±25ppm) establishes timing accuracy requirements. Operating temperature range (-40°C ~ 85°C) ensures thermal performance equivalence. Current specifications (35mA max supply, 22mA max disable) determine power budget compatibility. Package type (6-SMD, No Lead) and physical dimensions (0.098" L x 0.079" W, 0.035" max height) ensure PCB layout and assembly compatibility. Base resonator type (MEMS) and function (Enable/Disable) must match for functional equivalence.

The DSC1121DI2-025.0000T from Microchip Technology meets all these criteria and qualifies as a parametric equivalent.
