Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7M-24.576MAHI-T is determined by the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 24.576 MHz (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 3.20mm x 2.50mm (exact match required)

Allowable Variation Parameters:

• Load Capacitance: 12pF to 16pF (variation permitted within circuit design tolerance)
• ESR: 60 to 100 Ohms (variation permitted within circuit design tolerance)
• Height - Seated: 0.75mm to 0.80mm (variation permitted within PCB clearance tolerance)

Compliance Parameters:

• RoHS Status: RoHS Compliant or ROHS3 Compliant (both acceptable)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (exact match required)

The substitute parts 7M-24.576MAHE-T and C3E-24.576-12-3030-X-R meet all mandatory matching parameters. Variations in load capacitance and ESR are within acceptable engineering tolerances for crystal oscillator circuit design.

Parameter Comparison

Engineering Selection Recommendations

7M-24.576MAHE-T (TXC CORPORATION): This substitute maintains identical ESR (60 Ohms) and operating characteristics to the main part. The load capacitance reduction from 16pF to 12pF requires circuit validation to confirm compatibility with the oscillator circuit's load capacitance specification. Both parts are manufactured by TXC CORPORATION and carry RoHS Compliant status. This part is suitable for direct substitution when circuit design accommodates the 12pF load capacitance requirement.

C3E-24.576-12-3030-X-R (Aker Technology Corp): This substitute meets all mandatory frequency, stability, temperature, and package specifications. The ESR is elevated to 100 Ohms compared to the main part's 60 Ohms, and load capacitance is 12pF. The height is reduced to 0.75mm, providing additional PCB clearance margin. This part carries ROHS3 Compliant status, which exceeds RoHS Compliant requirements. Circuit validation is required to confirm ESR and load capacitance compatibility before implementation.

Both substitute parts carry identical REACH Unaffected and EAR99 ECCN classifications, ensuring regulatory compliance equivalence with the main part.

Frequently Asked Questions (FAQ)

Q: Can the 7M-24.576MAHE-T be used as a direct replacement for the 7M-24.576MAHI-T?

A: The 7M-24.576MAHE-T is electrically compatible for substitution provided the circuit design accommodates a 12pF load capacitance specification. The main part specifies 16pF load capacitance. Circuit validation is required to confirm the oscillator circuit's load capacitance tolerance range includes 12pF operation.

Q: What is the significance of the ESR difference between the main part (60 Ohms) and the C3E-24.576-12-3030-X-R (100 Ohms)?

A: ESR (Equivalent Series Resistance) affects crystal oscillator startup characteristics and power consumption. The C3E-24.576-12-3030-X-R's higher ESR of 100 Ohms requires circuit validation to confirm the oscillator circuit can reliably start and maintain stable oscillation. ESR compatibility depends on the specific oscillator circuit design and component values.

Q: Are there packaging differences between these parts?

A: The 7M-24.576MAHI-T is supplied in standard packaging. The 7M-24.576MAHE-T is supplied in Cut Tape (CT) packaging. The C3E-24.576-12-3030-X-R is supplied in Tape & Reel (TR) packaging. All three parts use identical 4-SMD, No Lead surface mount packages with 3.20mm x 2.50mm dimensions. Packaging format affects handling and assembly processes but does not impact electrical performance.

Q: Do all three parts meet current environmental compliance standards?

A: Yes. The 7M-24.576MAHI-T and 7M-24.576MAHE-T are RoHS Compliant. The C3E-24.576-12-3030-X-R is ROHS3 Compliant, which represents a more recent compliance standard. All three parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: What is the moisture sensitivity level for these parts?

A: All three parts carry MSL 1 (Unlimited) moisture sensitivity rating. This classification indicates the parts do not require special moisture control during storage, handling, or assembly, simplifying supply chain and manufacturing processes.

Q: Which substitute part should be selected if the circuit design requires 16pF load capacitance?

A: Neither substitute part matches the 16pF load capacitance specification of the main part. Both substitute parts specify 12pF load capacitance. If the circuit design requires 16pF load capacitance, the main part 7M-24.576MAHI-T should be used. Substitution with 12pF parts requires circuit redesign or validation to confirm operation within the oscillator circuit's load capacitance tolerance range.
