FN0200044 Equivalent & Substitute Parts

Part Overview

The FN0200044 is a 2.048 MHz XO (Standard) CMOS Oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FN series. This crystal oscillator operates at 3.3V with Enable/Disable functionality and is housed in a 4-SMD, No Lead package. The part is Active status and ROHS3 compliant. Substitute parts may be required due to inventory constraints, packaging format changes, or performance specification upgrades within the same electrical and mechanical compatibility envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for FN0200044 is determined by the following critical parameters: frequency (2.048 MHz), output type (CMOS), supply voltage (3.3V), Enable/Disable function, package type (4-SMD, No Lead), and mounting configuration (Surface Mount). All substitute parts must maintain these core electrical and mechanical specifications. Variations in frequency stability, operating temperature range, packaging format (Bulk vs. Tape & Reel), and series designation are permitted within the substitution matrix, provided the primary functional parameters remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (FN0200047, FN0200045, FNGEPO002) are Active status products manufactured by Diodes Incorporated and maintain ROHS3 compliance and REACH Unaffected status identical to FN0200044.

FN0200047 is a direct functional equivalent with improved frequency stability (±25ppm vs. ±50ppm) while maintaining identical operating temperature range, output type, and electrical specifications. This part is available in Bulk packaging.

FN0200045 differs in output type (LVCMOS vs. CMOS) and operating temperature range (-20°C ~ 70°C vs. -40°C ~ 85°C). This part is available in Tape & Reel packaging and is suitable only for applications within the narrower temperature specification.

FNGEPO002 maintains CMOS output type and ±50ppm frequency stability but operates within a narrower temperature range (-20°C ~ 70°C). This part belongs to the SaRonix-eCera™ ASSP XO™ series and is available in Tape & Reel packaging with a reduced seated height (0.061" vs. 0.071").

Frequently Asked Questions (FAQ)

Q: Can FN0200045 replace FN0200044 in all applications? A: FN0200045 is not a universal substitute. The LVCMOS output type differs from the CMOS output of FN0200044, and the operating temperature range is restricted to -20°C ~ 70°C. Substitution is valid only for applications operating within this narrower temperature envelope and compatible with LVCMOS logic levels.

Q: What is the primary difference between FN0200047 and FN0200044? A: FN0200047 provides improved frequency stability at ±25ppm compared to FN0200044's ±50ppm, while maintaining identical CMOS output, 3.3V supply, Enable/Disable function, and -40°C ~ 85°C operating temperature range. Both are available in Bulk packaging.

Q: Is FNGEPO002 compatible with FN0200044 in high-temperature applications? A: FNGEPO002 is not suitable for applications requiring operation above 70°C. The part is rated for -20°C ~ 70°C only. For applications requiring the full -40°C ~ 85°C range, FN0200044 or FN0200047 must be used.

Q: What packaging formats are available for these oscillators? A: FN0200044 and FN0200047 are available in Bulk packaging. FN0200045 and FNGEPO002 are available in Tape & Reel (TR) format. Packaging selection depends on assembly process requirements and volume specifications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. FN0200044, FN0200047, FN0200045, and FNGEPO002 are all ROHS3 compliant and REACH Unaffected, meeting identical environmental and regulatory requirements.
