FD3300023 Equivalent & Substitute Parts

Part Overview

The FD3300023 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 ROHS3 compliant. Substitute parts may be required due to inventory availability, packaging format preferences, or specific operating temperature and frequency stability requirements for particular applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FD3300023 is determined by the following critical parameters that must remain constant across all equivalent parts:

Fixed Parameters (Must Match):

• Frequency: 33 MHz
• Output Type: CMOS
• Voltage - Supply: 3.3V
• Function: Enable/Disable
• Package / Case: 4-SMD, No Lead
• Mounting Type: Surface Mount
• Physical Dimensions: 0.197" L x 0.126" W (5.00mm x 3.20mm)
• Height - Seated (Max): 0.051" (1.30mm)
• Current - Supply (Max): 15mA
• Current - Supply (Disable) (Max): 10µA
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Variable Parameters (May Differ):

• Frequency Stability: ±50ppm (FD3300023) vs. ±20ppm (FD3300020) vs. ±50ppm (FD3300021)
• Operating Temperature: -40°C ~ 85°C (FD3300023) vs. -20°C ~ 70°C (FD3300020, FD3300021)
• Packaging Format: Bulk (FD3300023, FD3300020) vs. Tape & Reel (FD3300021)

The FD3300020 and FD3300021 are direct substitutes for the FD3300023 within the SaRonix-eCera™ FD series, with differences limited to frequency stability tolerance, operating temperature range, and packaging delivery format.

Parameter Comparison

Engineering Selection Recommendations

All three parts—FD3300023, FD3300020, and FD3300021—are Active status products from Diodes Incorporated and carry ROHS3 compliance with MSL 1 rating. Selection between these parts depends on application-specific requirements:

FD3300023 (Bulk Packaging): Suitable for applications requiring extended operating temperature range (-40°C ~ 85°C) with standard frequency stability (±50ppm). Bulk packaging is appropriate for high-volume manufacturing environments.

FD3300020 (Bulk Packaging): Appropriate for applications with tighter frequency stability requirements (±20ppm) operating within the -20°C ~ 70°C temperature range. Bulk packaging format matches FD3300023 for supply chain consistency.

FD3300021 (Tape & Reel Packaging): Functionally equivalent to FD3300023 with identical frequency stability (±50ppm) and operating temperature range (-20°C ~ 70°C). Tape & Reel packaging is standard for automated assembly processes and high-speed production lines.

All parts maintain identical electrical performance within their specified operating ranges, physical footprint, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can FD3300020 replace FD3300023 in all applications?

A: FD3300020 is a direct substitute if your application operates within -20°C ~ 70°C and benefits from tighter frequency stability (±20ppm). If your application requires the extended temperature range (-40°C ~ 85°C) of FD3300023, FD3300020 is not suitable.

Q: What is the difference between Bulk and Tape & Reel packaging?

A: Bulk packaging (FD3300023, FD3300020) is supplied in loose quantities suitable for manual handling or small-scale assembly. Tape & Reel packaging (FD3300021) is wound on continuous tape for automated pick-and-place equipment, standard in high-volume manufacturing.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the identical 4-SMD, No Lead package with matching physical dimensions (5.00mm x 3.20mm) and height (1.30mm), ensuring direct PCB footprint compatibility.

Q: Does frequency stability affect circuit performance?

A: Frequency stability tolerance (±50ppm vs. ±20ppm) determines the maximum frequency deviation from the nominal 33 MHz specification. Applications with strict timing requirements may require the tighter ±20ppm specification of FD3300020.

Q: Are all parts RoHS compliant?

A: Yes. FD3300023, FD3300020, and FD3300021 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use FD3300021 in place of FD3300023 if I have automated assembly equipment?

A: Yes. FD3300021 is functionally equivalent to FD3300023 and is optimized for automated assembly via Tape & Reel packaging. Verify that your assembly equipment supports the tape format specifications.
