FN1000055 Equivalent & Substitute Parts

Part Overview

The FN1000055 is a 10 MHz crystal oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FN series. This CMOS oscillator operates at 3.3V with enable/disable functionality and is housed in a 4-SMD, No Lead package. The device is actively produced and ROHS3 compliant, making it suitable for modern electronic applications requiring precise frequency generation. Substitute parts are identified to provide design flexibility, supply chain alternatives, and extended operating temperature ranges where application requirements permit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Frequency: 10 MHz (exact match required)
• Output: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The FN1000055 has two qualified substitutes: FN1000057 (manufacturer-recommended alternative from Diodes Incorporated) and SXO75C3A271-10.000M (direct equivalent from Suntsu Electronics, Inc.). Both parts meet all critical electrical and mechanical parameters. Differences in operating temperature range and maximum supply current are noted but do not preclude substitution when application specifications permit.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and EAR99 export classification. Selection between FN1000055, FN1000057, and SXO75C3A271-10.000M depends on application-specific requirements:

FN1000055 and SXO75C3A271-10.000M are functionally equivalent with identical operating temperature ranges (-20°C ~ 70°C). FN1000057 extends the operating temperature range to -40°C ~ 85°C, providing suitability for applications requiring wider thermal performance. The SXO75C3A271-10.000M offers a reduced maximum height of 1.63mm compared to 1.80mm for the Diodes Incorporated parts, which may be advantageous in space-constrained designs. Maximum supply current specifications (15mA for Diodes parts, 16mA for Suntsu) are within acceptable tolerance for typical CMOS oscillator applications.

Frequently Asked Questions (FAQ)

Q: Can FN1000057 replace FN1000055 in all applications? A: FN1000057 is a direct substitute from the same manufacturer with identical electrical specifications. The extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C) makes it suitable for all applications where FN1000055 is used, plus applications requiring lower or higher temperature operation within the extended range.

Q: Is SXO75C3A271-10.000M compatible with FN1000055 designs? A: Yes. SXO75C3A271-10.000M meets all critical electrical and mechanical parameters. The 1.63mm maximum height is lower than FN1000055 (1.80mm), which is beneficial for space-constrained PCB layouts. Verify disable-mode current specifications with the Suntsu datasheet if this parameter is critical to your application.

Q: What are the key differences between these three parts? A: All three parts share identical frequency (10 MHz), output type (CMOS), supply voltage (3.3V), function (Enable/Disable), frequency stability (±50ppm), and package dimensions (7.00mm x 5.00mm). Differences include operating temperature range, maximum supply current, and package height. FN1000057 offers the widest temperature range; SXO75C3A271-10.000M offers the lowest profile.

Q: Are all parts suitable for high-volume production? A: All three parts are active products from established manufacturers with ROHS3 compliance. Current inventory levels are 894 pcs (FN1000055), 702 pcs (FN1000057), and 2902 pcs (SXO75C3A271-10.000M). Verify long-term availability and lead times with your component supplier for production commitments.

Q: Do these parts require any special handling or storage considerations? A: All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Standard ESD precautions for surface mount components apply.
