X2AEECNANF-24.000000 Equivalent & Substitute Parts

Part Overview

The X2AEECNANF-24.000000 is a 24 MHz fundamental mode crystal oscillator manufactured by Taitien, designed for surface mount applications in the 4-SMD, No Lead package. This part operates at ±30ppm frequency stability with an 8pF load capacitance and 70 Ohms equivalent series resistance across an operating temperature range of -20°C to 70°C. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Active alternative models from manufacturers including CTS-Frequency Controls and TXC CORPORATION provide functionally compatible solutions.

Engineering Selection Recommendations

Direct Replacement (8pF Load Capacitance):

For applications requiring exact load capacitance matching to the X2AEECNANF-24.000000, the following active parts are recommended:

7V-24.000MAAV-T (TXC CORPORATION): Active product status with 12,104 units in stock. ESR of 60 Ohms provides lower impedance than the original 70 Ohms specification. RoHS Compliant with REACH Unaffected status.
7V-24.000MEEV-T (TXC CORPORATION): Active product status with 923 units in stock. Identical electrical specifications to 7V-24.000MAAV-T with ESR of 60 Ohms. RoHS Compliant.
402F24033CKR (CTS-Frequency Controls): Active product status with 848 units in stock. ESR of 100 Ohms represents a higher impedance variant. ROHS3 Compliant with REACH Unaffected status.
7M-24.000MFEV-T (TXC CORPORATION): Active product status with 716 units in stock. ESR of 60 Ohms. RoHS Compliant with REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different load capacitance (9pF or 10pF) instead of 8pF?

A: Load capacitance affects the oscillation frequency in the circuit. Substitutes with 9pF or 10pF load capacitance will require circuit design adjustment to maintain the 24 MHz target frequency. Direct 8pF replacements eliminate this requirement.

Q: What is the significance of ESR (Equivalent Series Resistance) differences between substitute parts?

A: ESR affects the crystal's impedance and power consumption in the oscillator circuit. The original part specifies 70 Ohms. Substitutes range from 60 to 150 Ohms. Lower ESR (60 Ohms) reduces power consumption; higher ESR (100-150 Ohms) may require circuit tuning. Circuit compatibility should be evaluated based on the oscillator design specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original X2AEECNANF-24.000000 is ROHS3 Compliant. All substitute parts listed are either ROHS3 Compliant or RoHS Compliant, meeting environmental regulatory requirements.

Q: What is the difference between packaging options (Tape & Reel, Cut Tape, Digi-Reel)?

A: Packaging affects order quantity and handling. Tape & Reel (TR) and Cut Tape (CT) are standard formats for automated assembly. Digi-Reel is a proprietary format. All substitute parts use the same 4-SMD, No Lead physical package, ensuring mechanical compatibility regardless of packaging format.

Q: Which substitute part has the highest inventory availability?

A: 7V-24.000MAAV-T (TXC CORPORATION) has 12,104 units in stock, providing the highest availability among all substitute options.

Q: Can I mix substitute parts from different manufacturers in the same production run?

A: All substitute parts meet the same electrical specifications (24 MHz, ±30ppm, 4-SMD No Lead package, -20°C to 70°C operating range). Parts can be used interchangeably provided the circuit design accommodates the specific ESR and load capacitance of the selected part. Mixing manufacturers in a single production run is acceptable from an electrical standpoint but may require separate qualification testing per your quality procedures.
