FD3300020 Equivalent & Substitute Parts

Part Overview

The FD3300020 is a 33 MHz XO (Standard) CMOS Oscillator manufactured by Diodes Incorporated as 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 part is Active status and widely used in applications requiring stable frequency generation with low power consumption. Substitute parts may be required due to inventory constraints, packaging preferences, or specific operating condition requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts (FD3300020, FD3300021, FD3300023) are Active status products from Diodes Incorporated and are ROHS3 Compliant with REACH Unaffected status. They share identical electrical and mechanical specifications for frequency, output type, supply voltage, package dimensions, and mounting characteristics.

Selection between these parts should be based on:

1. Frequency Stability Requirements: FD3300020 provides ±20ppm stability, while FD3300021 and FD3300023 provide ±50ppm stability. Applications requiring tighter frequency tolerance should specify FD3300020.

2. Operating Temperature Range: FD3300023 supports -40°C ~ 85°C, providing extended temperature coverage compared to FD3300020 and FD3300021 (-20°C ~ 70°C). Applications in extreme temperature environments should specify FD3300023.

3. Packaging Format: FD3300020 and FD3300023 are supplied in Bulk packaging, while FD3300021 is supplied in Tape & Reel (TR) format. Packaging selection depends on assembly process requirements and volume considerations.

Frequently Asked Questions (FAQ)

Q: Can FD3300021 be used as a direct replacement for FD3300020?

A: FD3300021 is electrically and mechanically compatible with FD3300020. The primary difference is Frequency Stability (±50ppm vs. ±20ppm) and packaging format (Tape & Reel vs. Bulk). Substitution is valid if the application tolerates ±50ppm frequency stability.

Q: What is the difference between FD3300020 and FD3300023?

A: Both parts are supplied in Bulk packaging and share identical electrical specifications except for Frequency Stability (±20ppm vs. ±50ppm) and Operating Temperature Range (-20°C ~ 70°C vs. -40°C ~ 85°C). FD3300023 is suitable for applications requiring extended temperature operation.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the same 4-SMD, No Lead package with identical dimensions (5.00mm x 3.20mm) and height (1.30mm). They are mechanically and electrically interchangeable at the PCB level.

Q: Does packaging format affect electrical performance?

A: No. Bulk and Tape & Reel (TR) packaging formats contain identical components. The packaging format affects only the supply method and assembly process compatibility, not electrical or mechanical performance.

Q: Which part should be selected for high-reliability applications?

A: All three parts are Active status and ROHS3 Compliant. Selection should be based on specific application requirements: FD3300020 for tighter frequency stability, FD3300023 for extended temperature range, and FD3300021 for Tape & Reel assembly processes.
