FN3600001 Equivalent & Substitute Parts

Part Overview

The FN3600001 is a 36 MHz XO (Standard) CMOS oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FN series. This surface mount oscillator operates at 3.3V with enable/disable functionality and is housed in a 4-SMD, No Lead package. The part is currently in active production status with 710 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design requirements allow for alternative components that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FN3600001 must maintain compatibility across the following critical parameters:

• Frequency: Exact match at 36 MHz
• Output Configuration: CMOS output type
• Supply Voltage: 3.3V operation
• Enable/Disable Function: Active control capability required
• Package Type: 4-SMD, No Lead form factor
• Physical Footprint: 7.00mm x 5.00mm dimensions for PCB compatibility
• Mounting Method: Surface mount technology

The substitute part 7W-36.000MBB-T from TXC CORPORATION meets all these core requirements, enabling direct functional replacement in applications where the FN3600001 is specified.

Parameter Comparison

Engineering Selection Recommendations

The FN3600001 is the preferred primary selection due to its active product status and extended operating temperature range (-40°C ~ 85°C), which provides broader application compatibility across industrial and commercial temperature environments.

The 7W-36.000MBB-T serves as a functional substitute when the FN3600001 is unavailable. However, the following differences must be evaluated for specific applications:

• The substitute part operates within a narrower temperature range (-10°C ~ 70°C), limiting use in extended temperature applications
• Frequency stability specification is ±50ppm compared to ±25ppm for the primary part
• The substitute part is classified as obsolete, indicating limited future availability

Both parts maintain RoHS compliance and identical moisture sensitivity ratings, supporting environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7W-36.000MBB-T directly replace the FN3600001 in all applications?

A: Direct replacement is possible for applications operating within the temperature range of -10°C ~ 70°C. Applications requiring operation below -10°C or above 70°C require the FN3600001 or alternative parts with extended temperature specifications.

Q: What are the physical compatibility considerations?

A: Both parts share identical package dimensions (7.00mm x 5.00mm) and 4-SMD, No Lead form factor. The substitute part has a lower seated height (1.42mm vs. 1.80mm), which may provide clearance advantages in space-constrained designs but does not affect electrical compatibility.

Q: How do frequency stability differences impact circuit performance?

A: The FN3600001 provides ±25ppm stability while the 7W-36.000MBB-T provides ±50ppm stability. Applications with tight frequency tolerance requirements should specify the FN3600001. The difference represents a maximum frequency deviation of ±900 Hz at 36 MHz for the substitute part.

Q: Are there supply current differences between these parts?

A: The FN3600001 draws up to 25mA maximum supply current, while the 7W-36.000MBB-T draws up to 20mA. The substitute part offers lower power consumption, which may benefit battery-powered or power-constrained applications.

Q: What is the significance of the obsolete status for the 7W-36.000MBB-T?

A: Obsolete status indicates the part is no longer in active production. While 3171 units are currently in stock, future availability cannot be guaranteed. The FN3600001 should be prioritized for new designs requiring long-term supply assurance.
