FD4800046 48 MHz CMOS Crystal Oscillator Equivalent & Substitute Parts

Part Overview

The FD4800046 is a 48 MHz XO (Standard) CMOS crystal oscillator manufactured by Diodes Incorporated, designed for applications requiring a stable frequency reference with enable/disable functionality. This Surface Mount Device (SMD) operates at 3.3V supply voltage and is housed in a compact 4-SMD, No Lead package measuring 5.00mm × 3.20mm. The part is Active in product status and ROHS3 compliant, making it suitable for modern electronic applications requiring environmental compliance.

Equivalent and substitute parts are identified based on matching critical electrical and mechanical parameters: frequency (48 MHz), output type (CMOS), supply voltage (3.3V), function (Enable/Disable), package type (4-SMD, No Lead), and physical dimensions. These parameters define the interchangeability boundaries for direct component replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FD4800046 is determined by strict alignment with the following critical parameters:

• Frequency Match: 48 MHz (exact)
• Output Configuration: CMOS logic output
• Supply Voltage: 3.3V operation
• Functional Capability: Enable/Disable control
• Package Specification: 4-SMD, No Lead form factor
• Physical Footprint: 5.00mm × 3.20mm base dimensions
• Compliance Requirements: ROHS3 compliance and EAR99 classification

Parts meeting all these criteria are classified as direct substitutes. Variations in frequency stability, maximum supply current, or seated height do not preclude substitution when the core electrical and mechanical parameters align. The FD4800046 has two identified equivalent parts: the FD4800047 (Diodes Incorporated) and the SXO53C3A271-48.000M (Suntsu Electronics, Inc.).

Parameter Comparison

Engineering Selection Recommendations

All three parts—FD4800046, FD4800047, and SXO53C3A271-48.000M—are Active products with ROHS3 compliance and EAR99 classification, confirming their suitability for current design implementations and regulatory compliance requirements.

FD4800047 (Diodes Incorporated): This part offers improved frequency stability at ±25ppm compared to the FD4800046's ±50ppm, while maintaining identical electrical specifications and package dimensions. Both parts are manufactured by Diodes Incorporated and share the same supply current characteristics (15mA max, 10µA disable). The FD4800047 is a direct upgrade option when tighter frequency tolerance is required.

SXO53C3A271-48.000M (Suntsu Electronics, Inc.): This part matches the FD4800046 in frequency stability (±50ppm) and core electrical parameters. The maximum supply current is specified at 25mA, which is higher than the FD4800046's 15mA. The seated height is 1.40mm compared to 1.30mm for the Diodes parts. These differences do not affect PCB footprint compatibility but should be considered in applications with strict height constraints or power budget limitations.

Selection between these substitutes depends on specific application requirements: choose FD4800047 for enhanced frequency stability within the Diodes product line, or SXO53C3A271-48.000M for alternative sourcing from Suntsu Electronics with equivalent core functionality.

Frequently Asked Questions (FAQ)

Q: Can FD4800047 replace FD4800046 directly on the PCB?

A: Yes. Both parts share identical package specifications (4-SMD, No Lead), physical dimensions (5.00mm × 3.20mm), and seated height (1.30mm). Pin-to-pin compatibility is maintained, allowing direct substitution without PCB redesign.

Q: What is the difference between FD4800046 and FD4800047?

A: The primary difference is frequency stability: FD4800046 specifies ±50ppm, while FD4800047 specifies ±25ppm. All other electrical parameters, including supply voltage (3.3V), output type (CMOS), function (Enable/Disable), and supply current (15mA max), are identical. Both are manufactured by Diodes Incorporated.

Q: Can SXO53C3A271-48.000M be used as a substitute for FD4800046?

A: Yes, for applications where the higher maximum supply current (25mA vs. 15mA) and slightly increased seated height (1.40mm vs. 1.30mm) are acceptable. The core electrical parameters—frequency, output type, supply voltage, and function—are identical. Verify that your PCB layout accommodates the 0.10mm additional height.

Q: Are all three parts ROHS3 compliant?

A: Yes. FD4800046, FD4800047, and SXO53C3A271-48.000M are all ROHS3 compliant, meeting environmental and regulatory requirements for modern electronic applications.

Q: Which part should I select for lowest power consumption in disable mode?

A: FD4800046 and FD4800047 both specify 10µA maximum supply current in disable mode. SXO53C3A271-48.000M does not specify disable mode current. If disable mode power consumption is critical, select either Diodes part.

Q: Do these parts require any special handling or storage conditions?

A: All three parts have Moisture Sensitivity Level (MSL) 1 (Unlimited) or equivalent, indicating minimal moisture sensitivity. Standard ESD precautions and dry storage conditions are recommended for all Surface Mount Devices.
