FN0180037 Equivalent & Substitute Parts

Part Overview

The FN0180037 is a 1.843 MHz XO (Standard) CMOS Oscillator manufactured by Diodes Incorporated as part of the SaRonix-eCera™ FN series. This surface mount crystal oscillator operates at 3.3V with enable/disable functionality and is housed in a 4-SMD, No Lead package. The part is currently active in production with 1103 pieces in stock. Substitute parts are identified when equivalent electrical and mechanical specifications allow direct replacement in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

The FN0180035 qualifies as a direct substitute for the FN0180037 based on the following critical parameters:

• Identical frequency: 1.843 MHz
• Identical output type: CMOS
• Identical supply voltage: 3.3V
• Identical enable/disable function
• Identical frequency stability: ±50ppm
• Identical package and mechanical dimensions: 4-SMD, No Lead (7.00mm x 5.00mm x 1.80mm max height)
• Identical current specifications: 15mA max supply, 10µA max disable current
• Identical mounting type: Surface Mount
• Identical compliance certifications: ROHS3, MSL 1

The primary difference is the operating temperature range, where FN0180035 operates at -20°C ~ 70°C compared to FN0180037's -40°C ~ 85°C. This difference must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both FN0180037 and FN0180035 are active production parts from Diodes Incorporated with identical electrical and mechanical specifications. Selection between these parts depends on operating temperature requirements:

• Use FN0180037 for applications requiring the full -40°C ~ 85°C temperature range
• Use FN0180035 for applications operating within -20°C ~ 70°C, where higher inventory availability (6300 pieces) may provide supply chain advantages

Both parts carry ROHS3 compliance and MSL 1 rating, ensuring equivalent environmental and handling characteristics. Packaging format (Bulk for FN0180035 vs. standard for FN0180037) may affect procurement logistics but does not impact electrical performance or PCB integration.

Frequently Asked Questions (FAQ)

Q: Can FN0180035 replace FN0180037 in all applications?

A: FN0180035 can replace FN0180037 only in applications where the operating temperature range does not exceed -20°C to 70°C. If your application requires operation below -20°C or above 70°C, FN0180037 must be used.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the same 4-SMD, No Lead package with dimensions of 7.00mm x 5.00mm and maximum seated height of 1.80mm. PCB footprints and assembly processes are identical.

Q: Do both parts have the same electrical performance?

A: Yes. Frequency (1.843 MHz), frequency stability (±50ppm), output type (CMOS), supply voltage (3.3V), enable/disable function, and current specifications (15mA max, 10µA disable) are identical.

Q: What is the difference in packaging?

A: FN0180037 uses standard packaging while FN0180035 uses Bulk packaging. This affects order quantities and storage but does not impact component performance or compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both FN0180037 and FN0180035 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
