FN2000115 Equivalent & Substitute Parts

Part Overview

The FN2000115 is a 20 MHz crystal oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FN series. This CMOS 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. Equivalent and substitute parts are identified to support design flexibility, inventory management, and supply chain continuity for applications requiring 20 MHz CMOS oscillation with identical or compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FN2000115 are qualified based on the following critical parameters:

• Frequency: 20 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Frequency stability and current supply specifications may vary within acceptable tolerances for equivalent operation. Physical dimensions (length, width, height) must remain compatible with PCB layout and assembly constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts—FN2000115, FN2000118, and SXO75C3C481-20.000M—are Active status products with ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement.

FN2000115 and SXO75C3C481-20.000M both specify ±25ppm frequency stability, providing tighter tolerance for applications requiring higher frequency accuracy. FN2000118 specifies ±50ppm frequency stability and is suitable for applications with relaxed frequency tolerance requirements.

The Suntsu SXO75C3C481-20.000M offers a lower seated height of 0.063" (1.60mm) compared to 0.071" (1.80mm) for both Diodes parts, providing design flexibility for space-constrained PCB layouts. Maximum supply current for the Suntsu part is 16mA versus 15mA for Diodes parts, a negligible difference for most applications.

Selection between these parts should be based on frequency stability requirements, available inventory, and PCB height constraints.

Frequently Asked Questions (FAQ)

Q: Can FN2000118 be used as a direct replacement for FN2000115?

A: FN2000118 is mechanically and electrically compatible with FN2000115 in terms of package, pinout, supply voltage, and operating temperature range. The primary difference is frequency stability: FN2000118 specifies ±50ppm versus ±25ppm for FN2000115. Applications tolerating ±50ppm frequency deviation can use FN2000118 as a substitute.

Q: Is the Suntsu SXO75C3C481-20.000M a direct replacement?

A: Yes. The Suntsu part matches all critical electrical parameters: 20 MHz frequency, CMOS output, 3.3V supply, enable/disable function, and 4-SMD No Lead package. The lower seated height (0.063" versus 0.071") is advantageous for compact designs and does not prevent substitution.

Q: What are the key compatibility criteria for substitution?

A: Substitutes must match: frequency (20 MHz), output type (CMOS), supply voltage (3.3V), function (enable/disable), package type (4-SMD No Lead), mounting type (surface mount), and operating temperature range (-40°C ~ 85°C). Frequency stability and current specifications may vary within acceptable design margins.

Q: Are there any compliance or certification differences between these parts?

A: All three parts are ROHS3 compliant, REACH Unaffected, and carry EAR99 ECCN classification. No compliance or certification differences exist that would restrict substitution.

Q: Does the height difference between parts affect PCB assembly?

A: The Suntsu part's lower seated height (0.063" versus 0.071") is compatible with standard SMD assembly processes and does not create assembly conflicts. The reduced height may provide additional clearance in space-constrained designs.
