FD2000047 Equivalent & Substitute Parts

Part Overview

The FD2000047 is a 20 MHz XO (Standard) CMOS oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FD 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 actively produced and maintains full RoHS3 and REACH compliance. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, design flexibility, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FD2000047 is based on strict equivalence of the following critical parameters:

• Frequency: 20 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable capability (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 5.00mm × 3.20mm × 1.30mm maximum height (exact match required)
• Operating Temperature Range: -20°C ~ 70°C (exact match required)
• Mounting Type: Surface Mount (exact match required)

The FD2000046 qualifies as a direct substitute based on these parameters. The primary difference is frequency stability specification (±50ppm versus ±20ppm), which represents a relaxation of tolerance and does not prevent functional substitution in applications where the tighter stability of the FD2000047 is not required.

Parameter Comparison

Engineering Selection Recommendations

Both the FD2000047 and FD2000046 are active products from Diodes Incorporated with full RoHS3 compliance and REACH unaffected status. Selection between these parts depends on frequency stability requirements:

• FD2000047: Select when ±20ppm frequency stability is specified in the design or application requirements.
• FD2000046: Select when ±50ppm frequency stability is acceptable, or when the tighter tolerance of the FD2000047 is not required by the circuit design.

Both parts are identical in all other electrical and mechanical characteristics, including supply voltage, output type, operating temperature range, current consumption, package dimensions, and mounting configuration. PCB layout and assembly processes are interchangeable between these parts.

Frequently Asked Questions (FAQ)

Q: Can FD2000046 be used as a direct replacement for FD2000047 on the same PCB?

A: Yes. Both parts are identical in package type (4-SMD, No Lead), physical dimensions (5.00mm × 3.20mm × 1.30mm), and mounting type (Surface Mount). No PCB redesign or assembly process changes are required.

Q: What is the difference between FD2000047 and FD2000046?

A: The primary difference is frequency stability specification. FD2000047 specifies ±20ppm, while FD2000046 specifies ±50ppm. All other electrical and mechanical parameters are identical.

Q: Does frequency stability affect circuit performance?

A: Frequency stability determines the long-term accuracy of the oscillator output. Applications requiring precise timing or narrow frequency tolerance should use FD2000047. Applications with relaxed timing requirements may use FD2000046.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both FD2000047 and FD2000046 are ROHS3 Compliant and REACH Unaffected.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these oscillators be used in the same supply voltage circuit?

A: Yes. Both parts operate at 3.3V supply voltage with identical maximum supply current (15mA) and disable mode current (10µA).

Q: What is the operating temperature range for both parts?

A: Both parts operate across -20°C to 70°C.
