FN6400019 Equivalent & Substitute Parts

Part Overview

The FN6400019 is a 64 MHz XO (Standard) CMOS Oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FN 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 Active status and ROHS3 compliant. Substitute parts are identified when component availability is limited or when design requirements permit operation within alternative parameter ranges while maintaining core functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN6400019 is determined by strict equivalence across the following critical parameters:

• Frequency: 64 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 0.276" L x 0.197" W / 7.00mm x 5.00mm (exact match required)
• Height - Seated (Max): 0.071" (1.80mm) (exact match required)
• Current - Supply (Max): 40mA (exact match required)
• Current - Supply (Disable) (Max): 100µA (exact match required)

The FN6400017 qualifies as a substitute part based on full alignment with all critical electrical and mechanical parameters. The operating temperature range differs (-20°C ~ 70°C versus -40°C ~ 85°C); this represents a narrower specification window and must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the FN6400019 and FN6400017 are Active status products from Diodes Incorporated with identical ROHS3 compliance, REACH status, and regulatory classifications (EAR99, HTSUS 8542.39.0001). Both devices carry MSL 1 (Unlimited) moisture sensitivity ratings.

The primary differentiation is the operating temperature range. The FN6400019 supports -40°C ~ 85°C operation, while the FN6400017 supports -20°C ~ 70°C operation. Selection between these parts depends on whether the application environment requires the extended low-temperature (-40°C) or high-temperature (85°C) performance of the FN6400019. If the application operates within the -20°C ~ 70°C window, the FN6400017 is functionally equivalent across all other electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can FN6400017 be used as a direct replacement for FN6400019?

A: The FN6400017 is electrically and mechanically equivalent to the FN6400019 across all critical parameters including frequency, output type, supply voltage, package dimensions, and current specifications. The operating temperature range is narrower (-20°C ~ 70°C versus -40°C ~ 85°C). Substitution is valid only if the application does not require operation below -20°C or above 70°C.

Q: Are there any package or PCB layout differences between these parts?

A: No. Both parts use identical 4-SMD, No Lead packaging with matching physical dimensions (0.276" L x 0.197" W / 7.00mm x 5.00mm) and seated height (0.071" / 1.80mm). PCB footprints and assembly processes are interchangeable.

Q: What is the significance of the frequency stability specification?

A: Both parts specify ±50ppm frequency stability, which defines the maximum deviation from the nominal 64 MHz center frequency across the operating temperature range and supply voltage variations. This specification is identical between the two parts.

Q: Do both parts support Enable/Disable functionality?

A: Yes. Both the FN6400019 and FN6400017 include Enable/Disable function, allowing the oscillator output to be controlled via a logic input. Current consumption in the disabled state is 100µA (maximum) for both parts.

Q: Are there compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical regulatory classifications (EAR99, HTSUS 8542.39.0001). Moisture sensitivity level is 1 (Unlimited) for both devices.
