FN0200043 Equivalent & Substitute Parts

Part Overview

The FN0200043 is a 2.048 MHz XO (Standard) CMOS Oscillator manufactured by Diodes Incorporated as 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 availability, packaging format preferences, or specific operating temperature range requirements for particular applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN0200043 is determined by the following critical parameters: frequency (2.048 MHz), supply voltage (3.3V), function (Enable/Disable), package type (4-SMD, No Lead), and physical dimensions (7.00mm x 5.00mm). All qualified substitutes maintain these core specifications. Secondary parameters including output type (CMOS or LVCMOS), frequency stability tolerance, and operating temperature range may vary within acceptable limits for specific applications. Packaging format (Bulk vs. Tape & Reel) does not affect electrical compatibility but may influence procurement and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (FN0200045, FN0200047, FNGEPO002) are Active status products from Diodes Incorporated with ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility with the FN0200043.

FN0200045 differs in output type (LVCMOS vs. CMOS) and frequency stability (±50ppm vs. ±25ppm). Selection depends on circuit requirements for output voltage levels and timing precision tolerance.

FN0200047 maintains identical output type (CMOS) and frequency stability (±25ppm) as the FN0200043 but extends the operating temperature range to -40°C ~ 85°C, suitable for applications requiring wider thermal operation. Height specification remains equivalent at 0.071" (1.80mm).

FNGEPO002 operates within the same temperature range as FN0200043 (-20°C ~ 70°C) but features reduced seated height of 0.061" (1.55mm) and ±50ppm frequency stability. This part belongs to the SaRonix-eCera™ ASSP XO™ series rather than the FN series.

Frequently Asked Questions (FAQ)

Q: Can FN0200045 replace FN0200043 in all applications? A: FN0200045 is electrically compatible for frequency and supply voltage but uses LVCMOS output instead of CMOS. Verify circuit input requirements for LVCMOS signal levels. Frequency stability is ±50ppm versus ±25ppm on the original part.

Q: What is the primary advantage of FN0200047 over FN0200043? A: FN0200047 extends the operating temperature range to -40°C ~ 85°C while maintaining CMOS output and ±25ppm frequency stability. Use this part for applications requiring operation beyond the standard -20°C ~ 70°C range.

Q: Does FNGEPO002 fit in the same PCB footprint as FN0200043? A: Yes. Both parts use 4-SMD, No Lead package with 7.00mm x 5.00mm dimensions. FNGEPO002 has reduced height (0.061" vs. 0.071"), which may provide clearance advantages in space-constrained designs.

Q: Are there packaging format differences between these parts? A: FN0200043 and FN0200047 are supplied in Bulk packaging. FN0200045 and FNGEPO002 are supplied in Tape & Reel (TR) format. Packaging does not affect electrical performance but influences procurement and assembly processes.

Q: What is the frequency stability difference between parts? A: FN0200043 and FN0200047 specify ±25ppm stability. FN0200045 and FNGEPO002 specify ±50ppm stability. Applications with strict timing requirements should use ±25ppm parts.
