FN1000058 10 MHz CMOS Oscillator Equivalent & Substitute Parts

Part Overview

The FN1000058 is a 10 MHz XO (Standard) CMOS oscillator manufactured by Diodes Incorporated, 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 device is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified for applications requiring alternative sourcing, inventory management, or extended operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN1000058 is determined by the following critical parameters:

• Frequency: 10 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm) (exact match required)

Allowable variations within substitute parts include frequency stability tolerance, operating temperature range, maximum supply current, and seated height, provided all critical parameters remain identical. All substitute parts must maintain RoHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet the core functional and mechanical requirements for direct substitution in applications requiring a 10 MHz CMOS oscillator with 3.3V supply and enable/disable control in a 4-SMD, No Lead package.

FN1000058 and SXO75C3C271-10.000M are functionally equivalent, both offering ±25ppm frequency stability and identical operating temperature range (-20°C ~ 70°C). These parts are suitable for applications with standard temperature requirements and tighter frequency tolerance specifications.

FN1000057 extends the operating temperature range to -40°C ~ 85°C, making it suitable for industrial and automotive applications requiring wider temperature operation. This part accepts ±50ppm frequency stability, which may be acceptable in applications with less stringent timing requirements. FN1000057 maintains identical supply current specifications and disable current performance as the primary part.

All parts carry active product status, ROHS3 compliance, and MSL 1 rating, ensuring long-term availability and environmental regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can FN1000057 be used as a direct replacement for FN1000058?

A: Yes. Both parts share identical frequency, output type, supply voltage, function, package, and physical dimensions. FN1000057 differs in frequency stability (±50ppm vs. ±25ppm) and operating temperature range (-40°C ~ 85°C vs. -20°C ~ 70°C). Selection depends on application temperature requirements and frequency tolerance specifications.

Q: Is SXO75C3C271-10.000M compatible with FN1000058?

A: Yes. The Suntsu part matches all critical parameters: 10 MHz frequency, CMOS output, 3.3V supply, enable/disable function, 4-SMD No Lead package, and 7.00mm x 5.00mm dimensions. The seated height is 0.063" (1.60mm) compared to 0.071" (1.80mm) for the Diodes part, which may affect PCB layout clearance in space-constrained designs.

Q: What are the key differences between these three parts?

A: FN1000058 and SXO75C3C271-10.000M offer ±25ppm frequency stability and -20°C ~ 70°C operation. FN1000057 provides wider temperature range (-40°C ~ 85°C) with relaxed frequency stability (±50ppm). Maximum supply current varies slightly: FN1000058 and FN1000057 at 15mA, SXO75C3C271-10.000M at 16mA.

Q: Are all parts RoHS3 compliant?

A: Yes. FN1000058, FN1000057, and SXO75C3C271-10.000M are all ROHS3 compliant with MSL 1 rating (unlimited moisture sensitivity).

Q: Which part should I select for industrial temperature applications?

A: FN1000057 is specified for -40°C ~ 85°C operation, making it suitable for industrial and automotive environments. FN1000058 and SXO75C3C271-10.000M are rated for -20°C ~ 70°C and are appropriate for commercial temperature range applications.
