FD2500052 Equivalent & Substitute Parts

Part Overview

The FD2500052 is a 25 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 CMOS output logic. The device is Active status and widely used in applications requiring stable 25 MHz frequency generation with low power consumption. Substitute parts may be required due to inventory constraints, manufacturing discontinuation, or specific application requirements that align with alternative output logic specifications.

Substitute Part Grouping Explanation

The FD2500050 qualifies as a substitute for the FD2500052 based on the following matching parameters:

• Identical frequency: 25 MHz
• Identical supply voltage: 2.5V
• Identical function: Enable/Disable
• Identical package: 4-SMD, No Lead
• Identical physical dimensions: 0.197" L x 0.126" W (5.00mm x 3.20mm)
• Identical frequency stability: ±50ppm
• Identical manufacturer: Diodes Incorporated
• Identical series: SaRonix-eCera™ FD
• Identical RoHS compliance: ROHS3 Compliant

The primary difference is the output logic specification: FD2500052 provides CMOS output, while FD2500050 provides LVCMOS output. Both output types are compatible with 2.5V supply applications where the receiving circuit accepts low-voltage logic levels.

Parameter Comparison

Engineering Selection Recommendations

Both FD2500052 and FD2500050 are Active products with ROHS3 compliance and REACH Unaffected status, making them suitable for current production applications. Selection between these parts depends on the receiving circuit's logic level requirements:

• Use FD2500052 when the application circuit specifically requires standard CMOS output levels at 2.5V.
• Use FD2500050 when the application circuit accepts LVCMOS output levels at 2.5V.

The FD2500050 operates within a narrower temperature range (-20°C ~ 70°C) compared to the FD2500052 (-40°C ~ 85°C). Applications requiring extended low-temperature operation below -20°C or high-temperature operation above 70°C must use the FD2500052. Both parts share identical frequency stability, supply current characteristics, and physical package dimensions, ensuring mechanical and electrical compatibility within their respective operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between FD2500052 and FD2500050?

A: The output logic specification differs. FD2500052 provides CMOS output, while FD2500050 provides LVCMOS output. Both operate at 2.5V supply voltage with identical frequency and stability characteristics.

Q: Can FD2500050 replace FD2500052 in all applications?

A: FD2500050 can replace FD2500052 only when the receiving circuit accepts LVCMOS logic levels. Additionally, the operating temperature range of FD2500050 (-20°C ~ 70°C) is narrower than FD2500052 (-40°C ~ 85°C). Applications requiring operation outside this range must use FD2500052.

Q: Are the physical packages identical?

A: Both parts use the same 4-SMD, No Lead package with identical length and width dimensions (5.00mm x 3.20mm). The seated height differs slightly: FD2500052 is 1.30mm maximum, while FD2500050 is 1.35mm maximum. This minimal difference does not affect standard PCB layout compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both FD2500052 and FD2500050 are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes.

Q: What are the power consumption characteristics?

A: Both parts draw a maximum of 15mA during normal operation and 10µA maximum during disable mode at 2.5V supply voltage.
