Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FN0200045 are qualified based on the following criteria:

Critical Matching Parameters:

• Frequency: 2.048 MHz (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Function: Enable/Disable (exact match required)

Allowable Variations:

• Output Type: LVCMOS to CMOS (compatible logic family)
• Frequency Stability: ±50ppm to ±25ppm (tighter tolerance acceptable)
• Operating Temperature Range: -20°C ~ 70°C to -40°C ~ 85°C (extended range acceptable)
• Height - Seated (Max): 0.071" (1.80mm) to 0.061" (1.55mm) (reduced height acceptable)
• Packaging Format: Tape & Reel (TR) to Bulk (format variation acceptable)

The FN0200047 and FNGEPO002 meet all critical matching parameters and represent valid substitutes with enhanced or equivalent electrical characteristics.

Engineering Selection Recommendations

All three parts—FN0200045, FN0200047, and FNGEPO002—are Active status products manufactured by Diodes Incorporated and are ROHS3 compliant with REACH Unaffected status. Selection between these parts depends on application-specific requirements:

FN0200045 (Primary Part): Use when LVCMOS output is required and operating temperature range of -20°C ~ 70°C is acceptable. Packaged in Tape & Reel format.

FN0200047 (Upgrade Substitute): Use when CMOS output is acceptable and enhanced frequency stability of ±25ppm is required. Supports extended operating temperature range of -40°C ~ 85°C. Available in Bulk packaging.

FNGEPO002 (Manufacturer Recommended Substitute): Use when CMOS output is acceptable and reduced PCB height of 0.061" (1.55mm) is beneficial for space-constrained designs. Packaged in Tape & Reel format. Operates within the same temperature range as the primary part.

All parts maintain identical supply voltage (3.3V), frequency (2.048 MHz), current specifications, and package footprint dimensions (7.00mm x 5.00mm).

Frequently Asked Questions (FAQ)

Q: Can FN0200047 replace FN0200045 directly? A: Yes. FN0200047 is a direct substitute with CMOS output instead of LVCMOS. CMOS output is compatible with LVCMOS input requirements. FN0200047 offers tighter frequency stability (±25ppm vs ±50ppm) and extended operating temperature range (-40°C ~ 85°C vs -20°C ~ 70°C).

Q: What is the difference between LVCMOS and CMOS output? A: LVCMOS (Low Voltage CMOS) and CMOS are compatible logic families. CMOS output is acceptable for applications designed for LVCMOS input. Both operate at 3.3V supply voltage.

Q: Can FNGEPO002 be used in place of FN0200045? A: Yes. FNGEPO002 is a qualified substitute with identical electrical specifications and frequency. The primary difference is reduced seated height (0.061" vs 0.071"), which may be advantageous in height-constrained PCB designs. FNGEPO002 uses CMOS output instead of LVCMOS.

Q: Are there packaging differences between these parts? A: FN0200045 and FNGEPO002 are supplied in Tape & Reel (TR) format. FN0200047 is supplied in Bulk format. All three use identical 4-SMD, No Lead package configuration with 7.00mm x 5.00mm footprint.

Q: Do all three parts meet RoHS and REACH requirements? A: Yes. All three parts are ROHS3 compliant with REACH Unaffected status, suitable for applications requiring environmental compliance.

Q: What is the frequency stability difference between FN0200045 and FN0200047? A: FN0200045 has ±50ppm frequency stability. FN0200047 has ±25ppm frequency stability, representing a tighter tolerance. Both are suitable for 2.048 MHz timing applications; FN0200047 provides enhanced precision.

Q: Can these parts be used interchangeably in all applications? A: Substitution is valid when the application accepts CMOS output logic levels and the operating temperature range is compatible. Verify that your circuit design supports the output type and temperature requirements of the selected part.
