FDA000018 100 MHz CMOS Crystal Oscillator Equivalent & Substitute Parts

Part Overview

The FDA000018 is a 100 MHz XO (Standard) CMOS crystal oscillator manufactured by Diodes Incorporated, designed for applications requiring a 3.3V supply with enable/disable functionality. This Surface Mount Device (SMD) operates across the -20°C to 70°C temperature range and delivers CMOS-level output signals. The part is Active in product status and fully compliant with RoHS3 and REACH regulations. Substitute parts are identified when original inventory is unavailable or when design flexibility permits selection from qualified alternatives meeting equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FDA000018 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Equivalence Criteria:

• Frequency: 100 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Operating Temperature Range: -20°C ~ 70°C (exact match required)

Mechanical Compatibility Criteria:

• Package Type: 4-SMD, No Lead (exact match required)
• Package Dimensions: 5.00mm x 3.20mm (exact match required)
• Mounting Type: Surface Mount (exact match required)

Regulatory Compliance:

• RoHS3 Compliant (required)
• REACH Unaffected (required)

Frequency stability and supply current specifications may vary within acceptable ranges for the application category. Parts meeting all electrical, mechanical, and regulatory criteria are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

FDA000017 (Diodes Incorporated): This part is a manufacturer-recommended substitute from the same OEM. Both parts share identical electrical specifications with the exception of frequency stability (±50ppm versus ±25ppm for the FDA000018). Selection of FDA000017 is appropriate when the application tolerance permits ±50ppm stability and when maintaining a single-source manufacturer is preferred. Both parts carry Active product status and full RoHS3/REACH compliance.

SXO53C3C271-100.000M (Suntsu Electronics, Inc.): This part qualifies as a direct substitute based on matching frequency, output type, supply voltage, function, operating temperature range, and package specifications. The SXO53C3C271-100.000M exhibits frequency stability of ±25ppm (matching the FDA000018) and operates within identical temperature parameters. Maximum supply current is specified at 50mA (5mA higher than FDA000018). Maximum seated height is 1.40mm (0.10mm taller than FDA000018). All parts maintain Active product status and ROHS3 compliance. Selection of the Suntsu part is appropriate when cross-manufacturer sourcing is acceptable and when higher current capacity provides design margin.

Frequently Asked Questions (FAQ)

Q: Can FDA000017 be used as a direct replacement for FDA000018? A: FDA000017 is electrically compatible with FDA000018 in all critical parameters except frequency stability. FDA000017 specifies ±50ppm stability versus ±25ppm for FDA000018. Selection depends on application tolerance requirements. Both parts are manufactured by Diodes Incorporated and share identical package specifications.

Q: What are the key differences between the Diodes and Suntsu oscillators? A: The primary differences are manufacturer source and maximum supply current. Suntsu SXO53C3C271-100.000M specifies 50mA maximum supply current compared to 45mA for Diodes parts. The Suntsu part also has a maximum seated height of 1.40mm versus 1.30mm for FDA000018. Frequency stability and all electrical parameters remain equivalent.

Q: Are all three parts pin-compatible? A: All three parts use the 4-SMD, No Lead package type with identical 5.00mm x 3.20mm footprint dimensions. PCB layout compatibility is assured. Height differences (1.30mm for Diodes parts, 1.40mm for Suntsu) are within typical assembly tolerances for SMD applications.

Q: Do all substitute parts meet the same regulatory requirements? A: Yes. FDA000018, FDA000017, and SXO53C3C271-100.000M are all ROHS3 Compliant and carry REACH Unaffected status. All parts are classified as Active products with unrestricted moisture sensitivity levels (MSL 1).

Q: Which part should be selected for new designs? A: Selection is based on availability, supply chain strategy, and application frequency stability requirements. FDA000018 and SXO53C3C271-100.000M both offer ±25ppm stability. FDA000017 offers ±50ppm stability. All three parts are functionally qualified for 100 MHz CMOS oscillator applications with 3.3V supply and enable/disable control.
