Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FKA000005 are qualified based on the following critical parameters:

• Frequency: 100 MHz (exact match required)
• Output: 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)
• Physical Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)

Variations in frequency stability, operating temperature range, supply current, and height are permitted within the allowed electrical and mechanical tolerances for this product category. All substitute parts must maintain Active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet the core substitution criteria for the FKA000005. Selection between these parts is determined by application-specific requirements:

FKA000005 (Diodes Incorporated): Primary part with ±25ppm frequency stability and operating temperature range of -20°C ~ 70°C. Supply current maximum of 18mA.

FKA000006 (Diodes Incorporated): Manufacturer-recommended substitute with wider operating temperature range (-40°C ~ 85°C) and lower frequency stability (±50ppm). Supply current maximum of 18mA. Suitable for applications requiring extended temperature operation.

SXO32C3C271-100.000M (Suntsu Electronics, Inc.): Direct manufacturer alternative with ±25ppm frequency stability matching the primary part. Operating temperature range of -20°C ~ 70°C. Supply current maximum of 25mA. Height specification of 0.047" (1.20mm) is 0.002" greater than primary part.

All parts are Active status, ROHS3 compliant, and suitable for direct substitution in 100 MHz CMOS oscillator applications with 3.3V supply and Enable/Disable control.

Frequently Asked Questions (FAQ)

Q: Can FKA000006 replace FKA000005 in all applications? A: FKA000006 is electrically compatible as a substitute. The primary difference is frequency stability (±50ppm versus ±25ppm) and extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C). Applications requiring ±25ppm stability should use FKA000005 or SXO32C3C271-100.000M.

Q: What are the physical compatibility considerations for SXO32C3C271-100.000M? A: SXO32C3C271-100.000M has identical length, width, and package type. The seated height is 0.047" (1.20mm) compared to 0.045" (1.15mm) for FKA000005. This 0.002" difference must be evaluated for PCB layout and enclosure clearance.

Q: Are all three parts suitable for high-temperature applications? A: FKA000006 operates to 85°C maximum, making it suitable for extended temperature environments. FKA000005 and SXO32C3C271-100.000M are rated to 70°C maximum. Application temperature requirements determine part selection.

Q: What is the difference in supply current between these parts? A: FKA000005 and FKA000006 both specify 18mA maximum supply current. SXO32C3C271-100.000M specifies 25mA maximum. Power budget constraints may influence part selection.

Q: Are all parts RoHS compliant? A: All three parts are ROHS3 compliant and suitable for applications with RoHS requirements.
