Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FN1220026 are qualified based on the following critical parameters that must remain constant:

• Frequency: 12.288 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)
• Size / Dimension: 0.276" L x 0.197" W (7.00mm x 5.00mm) (exact match required)
• Height - Seated (Max): 0.071" (1.80mm) (exact match required)

The substitute parts FN1220024 and FN1220025 maintain all critical electrical and mechanical parameters. Variations in frequency stability and operating temperature range are permitted within the allowed parameter set for this product category.

Parameter Comparison

Engineering Selection Recommendations

All three parts—FN1220026, FN1220024, and FN1220025—are Active status products from Diodes Incorporated and maintain ROHS3 compliance and MSL 1 rating. Selection between these parts should be based on the following criteria:

FN1220026 is the primary choice when frequency stability of ±25ppm is required and operating temperature range of -20°C ~ 70°C is sufficient.

FN1220024 is suitable as a substitute when frequency stability of ±50ppm is acceptable and operating temperature range of -20°C ~ 70°C meets application requirements.

FN1220025 is suitable as a substitute when an extended operating temperature range of -40°C ~ 85°C is required, with frequency stability of ±50ppm.

All parts share identical electrical characteristics (3.3V supply, 15mA max current, 10µA disable current) and mechanical specifications (4-SMD No Lead package, 7.00mm x 5.00mm footprint, 1.80mm max height). Substitution is electrically and mechanically valid across all three parts within their respective operating parameters.

Frequently Asked Questions (FAQ)

Q: Can FN1220024 or FN1220025 be used as direct replacements for FN1220026?

A: Yes. All three parts maintain identical frequency (12.288 MHz), output type (CMOS), supply voltage (3.3V), function (Enable/Disable), and package specifications (4-SMD, No Lead, 7.00mm x 5.00mm). Substitution is electrically and mechanically valid.

Q: What is the difference in frequency stability between these parts?

A: FN1220026 provides ±25ppm frequency stability. FN1220024 and FN1220025 provide ±50ppm frequency stability. Applications requiring tighter frequency tolerance should use FN1220026.

Q: Which part should I select for extended temperature operation?

A: FN1220025 supports an operating temperature range of -40°C ~ 85°C, compared to -20°C ~ 70°C for FN1220026 and FN1220024. Select FN1220025 when extended temperature range is required.

Q: Are there packaging differences between these parts?

A: FN1220026 is supplied in standard packaging. FN1220024 and FN1220025 are supplied in Bulk packaging. All three parts use identical 4-SMD, No Lead package geometry and are surface mount compatible.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. All are Active status products from Diodes Incorporated.

Q: What is the current consumption difference in disable mode?

A: All three parts consume a maximum of 10µA in disable mode, providing identical low-power standby characteristics.
