Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FN1220027 are qualified based on the following criteria:

• Identical frequency: 12.288 MHz
• Identical output type: CMOS
• Identical supply voltage: 3.3V
• Identical function: Enable/Disable
• Identical package and mechanical dimensions: 4-SMD, No Lead (7.00mm x 5.00mm x 1.80mm max height)
• Identical mounting type: Surface Mount
• Identical current specifications: 15mA max supply, 10µA max disable current
• Identical compliance status: ROHS3 Compliant, MSL 1

Frequency stability and operating temperature range are allowed to vary within the substitute group, as these parameters do not affect mechanical or electrical interface compatibility in this oscillator category.

Parameter Comparison

Engineering Selection Recommendations

All three parts—FN1220027, FN1220024, and FN1220025—are Active status products from Diodes Incorporated with identical ROHS3 compliance and REACH Unaffected status. They share identical electrical interface specifications (3.3V supply, CMOS output, Enable/Disable function) and mechanical compatibility (4-SMD, No Lead package, 7.00mm x 5.00mm x 1.80mm).

FN1220027 offers the tightest frequency stability at ±25ppm and the widest operating temperature range (-40°C ~ 85°C). FN1220024 has a narrower operating temperature range (-20°C ~ 70°C) with ±50ppm frequency stability. FN1220025 matches FN1220027 in operating temperature range (-40°C ~ 85°C) but has ±50ppm frequency stability.

Selection between these parts depends on application-specific requirements for frequency stability and operating temperature range. All three are electrically and mechanically interchangeable at the board level.

Frequently Asked Questions (FAQ)

Q: Can FN1220024 replace FN1220027 in all applications?

A: FN1220024 is mechanically and electrically compatible with FN1220027 for board-level integration. However, FN1220024 operates over -20°C ~ 70°C versus FN1220027's -40°C ~ 85°C range, and has ±50ppm frequency stability versus ±25ppm. Applications requiring extended temperature operation or tighter frequency tolerance should use FN1220027 or FN1220025.

Q: What is the difference between FN1220024 and FN1220025?

A: Both parts have identical electrical and mechanical specifications except for operating temperature range. FN1220024 operates -20°C ~ 70°C, while FN1220025 operates -40°C ~ 85°C. Both have ±50ppm frequency stability. Selection depends on the required operating temperature envelope.

Q: Are all three parts pin-compatible?

A: Yes. FN1220027, FN1220024, and FN1220025 share identical 4-SMD, No Lead package dimensions (7.00mm x 5.00mm x 1.80mm max height) and are pin-compatible for direct board-level substitution.

Q: Do these oscillators require any special handling?

A: All three parts have MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control is required during storage or handling. Standard ESD precautions for surface mount components apply.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.
