FKA000008 100 MHz CMOS Oscillator Equivalent & Substitute Parts

Part Overview

The FKA000008 is a 100 MHz XO (Standard) CMOS oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FK series. This surface mount crystal oscillator provides a 3.3V enable/disable function with CMOS output, designed for applications requiring stable 100 MHz frequency generation. The part is active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when inventory constraints, extended temperature range requirements, or manufacturer availability necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FKA000008 are qualified based on the following critical parameters that determine functional and mechanical interchangeability:

• 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)
• Frequency Stability: ±50ppm (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Size / Dimension: 0.126" L x 0.098" W (3.20mm x 2.50mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)

Variations in operating temperature range, maximum supply current, and height-seated specifications do not preclude substitution when the above parameters are identical. The FKA000006 (Diodes Incorporated) and SXO32C3A271-100.000M (Suntsu Electronics) meet all critical substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

All three parts—FKA000008, FKA000006, and SXO32C3A271-100.000M—are active production components with ROHS3 compliance and REACH unaffected status, qualifying them for equivalent substitution in applications requiring 100 MHz CMOS oscillators with 3.3V enable/disable functionality.

FKA000006 (Diodes Incorporated) extends the operating temperature range to -40°C ~ 85°C compared to the FKA000008's -20°C ~ 70°C, making it suitable for applications requiring wider thermal performance without electrical parameter changes.

SXO32C3A271-100.000M (Suntsu Electronics) maintains identical core electrical specifications and operating temperature range as the FKA000008. The maximum supply current is specified at 25mA versus 18mA for the Diodes parts, and the seated height is 0.047" (1.20mm) versus 0.045" (1.15mm). These dimensional and current variations remain within typical PCB layout tolerances for 4-SMD, No Lead packages.

Selection between these parts depends on inventory availability, thermal requirements, and supplier preference, as all meet the critical electrical and mechanical substitution criteria.

Frequently Asked Questions (FAQ)

Q: Can FKA000006 replace FKA000008 in existing designs?

A: Yes. FKA000006 is electrically and mechanically equivalent to FKA000008 across all critical parameters: 100 MHz frequency, CMOS output, 3.3V supply, enable/disable function, ±50ppm stability, and 4-SMD, No Lead package. The extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C) provides additional thermal margin without affecting standard operation.

Q: Can SXO32C3A271-100.000M replace FKA000008?

A: Yes. SXO32C3A271-100.000M meets all critical electrical and mechanical substitution criteria. The maximum supply current specification of 25mA (versus 18mA) and seated height of 0.047" (1.20mm) (versus 0.045" (1.15mm)) are within acceptable tolerances for 4-SMD, No Lead surface mount oscillators and do not affect functional compatibility.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by exact matching of frequency (100 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, frequency stability (±50ppm), package type (4-SMD, No Lead), physical dimensions (0.126" L x 0.098" W), and surface mount mounting type. Variations in operating temperature range, maximum supply current, and height specifications do not preclude substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. FKA000008, FKA000006, and SXO32C3A271-100.000M are all ROHS3 compliant with REACH unaffected status, meeting current environmental and regulatory requirements.

Q: What is the difference in seated height between these parts?

A: FKA000008 and FKA000006 have a maximum seated height of 0.045" (1.15mm), while SXO32C3A271-100.000M is specified at 0.047" (1.20mm). This 0.002" (0.05mm) difference is negligible for standard PCB assembly and does not affect component placement or clearance in typical applications.
