Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for FN3000035 is determined by the following critical parameters:

• Frequency: 30 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)
• Physical Dimensions: 0.276" L x 0.197" W, 0.071" height (exact match required)
• Mounting Type: Surface Mount (exact match required)

Allowable variations within substitution:

• Frequency Stability: ±25ppm to ±50ppm tolerance range
• Operating Temperature Range: Extended range acceptable (-40°C ~ 85°C covers -20°C ~ 70°C)
• Current Supply (Max): 15mA (identical across all parts)
• Current Supply (Disable): 10µA (identical across all parts)

Both FN3000038 and FN3000041 meet these substitution criteria for FN3000035.

Parameter Comparison

Engineering Selection Recommendations

FN3000035, FN3000038, and FN3000041 are all Active status products from Diodes Incorporated with identical ROHS3 compliance and REACH Unaffected status. All three parts are suitable for direct substitution based on electrical and mechanical compatibility.

FN3000038 differs from FN3000035 in frequency stability (±50ppm versus ±25ppm) while maintaining identical operating temperature range. This part is appropriate for applications where the wider tolerance is acceptable.

FN3000041 extends the operating temperature range to -40°C ~ 85°C while maintaining ±25ppm frequency stability. This part is appropriate for applications requiring extended temperature operation beyond the -20°C ~ 70°C range of FN3000035.

All three parts share identical supply current specifications, package dimensions, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can FN3000038 replace FN3000035 in all applications?

A: FN3000038 is electrically and mechanically compatible with FN3000035. The primary difference is frequency stability tolerance (±50ppm versus ±25ppm). Substitution is valid where the application circuit tolerates the wider frequency stability specification.

Q: What is the key difference between FN3000035 and FN3000041?

A: Both parts maintain ±25ppm frequency stability and identical electrical characteristics. FN3000041 extends the operating temperature range to -40°C ~ 85°C, compared to FN3000035 at -20°C ~ 70°C. FN3000041 is suitable for applications requiring operation at temperatures below -20°C or above 70°C.

Q: Are all three parts pin-compatible?

A: Yes. FN3000035, FN3000038, and FN3000041 share identical 4-SMD, No Lead package specifications with matching physical dimensions (7.00mm x 5.00mm x 1.80mm height). Direct PCB footprint compatibility is confirmed.

Q: Do these parts require different handling or storage procedures?

A: No. All three parts carry MSL Rating 1 (Unlimited), indicating identical moisture sensitivity and storage requirements.

Q: Which part should be selected for cost optimization?

A: Part selection should be based on application requirements for frequency stability and operating temperature range. FN3000038 offers the widest tolerance specification. FN3000035 and FN3000041 both provide ±25ppm stability; FN3000041 is required only for extended temperature applications.
