FDC500014 Equivalent & Substitute Parts

Part Overview

The FDC500014 is a 125 MHz XO (Standard) CMOS Oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FD series. This surface mount crystal oscillator operates at 2.5V with Enable/Disable functionality and is housed in a 4-SMD, No Lead package. The device is Active status and ROHS3 compliant, making it suitable for applications requiring stable frequency generation with low power consumption in disabled mode. Substitute parts are identified when equivalent electrical and mechanical specifications are met within the allowed parameter tolerances for this oscillator category.

Substitute Part Grouping Explanation

Substitution for the FDC500014 is determined by strict equivalence across the following critical parameters:

• Frequency: 125 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -20°C ~ 70°C (exact match required)
• Current - Supply (Max): 35mA (exact match required)
• Current - Supply (Disable) (Max): 10µA (exact match required)
• Physical Dimensions: 0.197" L x 0.126" W, Height 0.051" (exact match required)

The FDC500015 qualifies as a substitute part because it meets all critical electrical and mechanical parameters. The difference in Frequency Stability (±25ppm vs. ±50ppm) represents an improvement in the substitute part and does not prevent substitution.

Parameter Comparison

Engineering Selection Recommendations

Both FDC500014 and FDC500015 are Active status products from Diodes Incorporated and carry ROHS3 compliance with REACH Unaffected status. Selection between these parts should be based on application requirements for frequency stability. The FDC500015 provides tighter frequency stability at ±25ppm compared to the FDC500014 at ±50ppm, making it suitable for applications with stricter frequency tolerance requirements. Both parts are identical in all other electrical and mechanical specifications, including supply voltage, current consumption, package dimensions, and operating temperature range. The choice between these oscillators depends solely on the frequency stability margin required by the end application.

Frequently Asked Questions (FAQ)

Q: Can FDC500015 be used as a direct replacement for FDC500014?

A: Yes. The FDC500015 meets all critical electrical and mechanical parameters of the FDC500014, including frequency, output type, supply voltage, package configuration, and physical dimensions. The improved frequency stability of FDC500015 does not prevent substitution.
