FK5000020 Equivalent & Substitute Parts

Part Overview

The FK5000020 is a 50 MHz XO (Standard) CMOS oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FK series. This surface mount crystal oscillator operates at 1.8V with Enable/Disable functionality, designed for applications requiring stable frequency generation in compact form factors. The device is Active status and widely used in digital systems requiring precise timing references. Substitute parts are identified when inventory constraints, lead time requirements, or specific operational temperature ranges necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the FK5000020 is determined by strict equivalence across the following critical parameters:

• Frequency: 50 MHz (exact match required)
• Output Configuration: CMOS (exact match required)
• Supply Voltage: 1.8V (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 3.20mm x 2.50mm (exact match required)
• Maximum Supply Current: 7mA (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The FK5000019 qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. Variations in operating temperature range and packaging format (Bulk vs. standard) do not affect functional substitutability for applications within the FK5000020's specified temperature window.

Parameter Comparison

Engineering Selection Recommendations

The FK5000019 is a qualified substitute for the FK5000020 based on complete electrical and mechanical equivalence. Both parts maintain Active product status within the SaRonix-eCera™ FK series and carry identical RoHS3 and REACH compliance certifications. The FK5000019 offers an extended operating temperature range (-40°C ~ 85°C) compared to the FK5000020 (-20°C ~ 70°C), providing additional thermal margin for applications operating at temperature extremes. Selection between these parts should be based on inventory availability, packaging requirements (Bulk vs. standard), and specific application temperature requirements. For applications constrained to the FK5000020's temperature window, both parts deliver equivalent performance.

Frequently Asked Questions (FAQ)

Q: Can FK5000019 replace FK5000020 in existing designs? A: Yes. Both parts are electrically and mechanically identical across all critical parameters including frequency, output type, supply voltage, stability, package type, and physical dimensions. Direct substitution is valid for applications operating within the FK5000020's specified temperature range of -20°C to 70°C.

Q: What is the difference between FK5000020 and FK5000019? A: The primary differences are packaging format (standard vs. Bulk) and operating temperature range. FK5000019 supports -40°C to 85°C operation, while FK5000020 is rated -20°C to 70°C. All electrical specifications and mechanical dimensions are identical.

Q: Are there any compatibility concerns with the 4-SMD, No Lead package? A: No. Both parts use identical 4-SMD, No Lead packaging with matching 3.20mm x 2.50mm footprint and 1.15mm maximum height. PCB layout and reflow profiles remain unchanged during substitution.

Q: Do both parts meet the same compliance standards? A: Yes. Both FK5000020 and FK5000019 are ROHS3 Compliant, REACH Unaffected, and carry identical MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Which part should be selected for extended temperature applications? A: For applications requiring operation below -20°C or above 70°C, FK5000019 with its -40°C to 85°C rating is the appropriate selection. For applications within -20°C to 70°C, either part is suitable based on availability.
