ASDMPC-25.000MHZ-LR-T Equivalent & Substitute Parts

Part Overview

The ASDMPC-25.000MHZ-LR-T is a 25 MHz MEMS-based XO (Standard) CMOS oscillator manufactured by Abracon LLC. This component operates across a 2.25V to 3.6V supply range with Enable/Disable functionality, housed in a 6-SMD, No Lead package. The oscillator is classified as Active product status and is suitable for applications requiring stable frequency generation with low power consumption in disable mode. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the critical performance parameters.

Substitute Part Grouping Explanation

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

Frequency: 25 MHz (exact match required)
Output Type: CMOS
Voltage Supply Range: 2.25V ~ 3.6V (identical range)
Frequency Stability: ±25ppm
Operating Temperature Range: -40°C ~ 85°C
Current Specifications: 35mA max supply, 22mA max disable
Function: Enable/Disable capability
Base Resonator: MEMS technology
Package: 6-SMD, No Lead with identical physical dimensions (2.50mm x 2.00mm, height 0.90mm max)
Compliance: ROHS3 Compliant, REACH Unaffected

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