Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FH3000007 are qualified based on the following criteria:

Mandatory Matching Parameters:

• Frequency: 30.0000 MHz (exact match required)
• Frequency Stability: ±30 ppm (substitute must meet or exceed this specification)
• Operating Mode: Fundamental
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, No Lead
• Operating Temperature Range: -20°C to 70°C (minimum)

Allowable Variation Parameters:

• Load Capacitance: Substitutes may vary within circuit design tolerance; circuit impedance matching must be verified
• ESR: Substitutes may vary; oscillator drive level capability must accommodate the specified ESR value
• Physical Dimensions: Minor variations acceptable within SMD assembly equipment specifications
• Moisture Sensitivity Level: MSL 1 is standard for this category; no restriction on substitution

Compliance Requirements:

• RoHS Status: Substitute must maintain equivalent or superior compliance level
• REACH Status: Substitute must maintain REACH Unaffected status

The TXC CORPORATION 8Y-30.000MAAJ-T qualifies as a direct substitute based on matching all mandatory parameters and maintaining equivalent regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (FH3000007): Use as the baseline selection when supply is available. Diodes Incorporated maintains active production status with confirmed inventory of 720 units. ROHS3 compliance and REACH Unaffected status meet current regulatory requirements.

Substitute Part (8Y-30.000MAAJ-T): The TXC CORPORATION 8Y-30.000MAAJ-T is qualified as a direct substitute when FH3000007 availability is constrained. This part maintains identical frequency, stability, and temperature specifications. Higher inventory availability (882 units) provides supply chain advantage.

Selection Considerations:

Load Capacitance Difference (20 pF vs. 18 pF): The 2 pF variance requires circuit verification. The oscillator circuit must be evaluated to confirm that the load capacitance specification of the substitute part does not introduce unacceptable frequency drift or startup behavior. This is a design-level consideration, not a component-level incompatibility.

ESR Difference (60 Ohms vs. 80 Ohms): The 20 Ohm increase in ESR affects oscillator drive level requirements. Verify that the oscillator IC or circuit driving the crystal can accommodate the higher ESR specification. Most modern oscillator circuits are designed with sufficient drive capability to handle this variance.

Physical Dimensions: The TXC part features a smaller footprint (2.00mm x 1.60mm vs. 2.50mm x 2.00mm) and lower profile (0.55mm vs. 0.70mm). These dimensions are compatible with standard SMD assembly equipment and do not present placement or clearance issues.

Both parts carry equivalent compliance certifications and MSL ratings, ensuring no additional handling or storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the 8Y-30.000MAAJ-T be used as a direct drop-in replacement for the FH3000007?

A: The 8Y-30.000MAAJ-T is electrically and mechanically compatible for most applications. However, the 2 pF load capacitance difference and 20 Ohm ESR increase require circuit-level verification. The oscillator circuit must be confirmed to operate within specification with these parameter variations. Physical dimensions are compatible with standard PCB layouts.

Q: What is the impact of the 2 pF load capacitance difference?

A: Load capacitance affects the oscillator circuit's tuning and frequency stability. A 2 pF reduction (from 20 pF to 18 pF) may shift the operating frequency slightly. The oscillator circuit design determines whether this shift falls within acceptable tolerance. Circuit simulation or bench testing is the appropriate method to confirm compatibility for your specific application.

Q: Does the higher ESR of the substitute part affect performance?

A: ESR determines the power required to drive the crystal. The 80 Ohm ESR of the substitute part requires more drive current than the 60 Ohm specification of the primary part. Modern oscillator ICs are typically designed with sufficient drive capability to accommodate this variance. Verify that your oscillator circuit specifications support the higher ESR value.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts maintain RoHS compliance and REACH Unaffected status. The FH3000007 carries ROHS3 designation while the 8Y-30.000MAAJ-T carries standard RoHS designation; both meet current regulatory requirements. Moisture Sensitivity Level is identical (MSL 1, Unlimited) for both parts.

Q: Can I use the substitute part in a design already qualified with the primary part?

A: The substitute part is electrically and mechanically compatible, but design re-qualification is recommended due to the load capacitance and ESR differences. These parameters affect oscillator performance characteristics. Conduct frequency stability testing and startup behavior verification with the substitute part in your specific circuit before production deployment.

Q: What are the inventory implications of using the substitute part?

A: The 8Y-30.000MAAJ-T has higher current inventory availability (882 units vs. 720 units). This may provide supply chain advantages during periods of component shortage. Both parts are in active production status.

Q: Are the physical dimension differences significant?

A: The TXC part is smaller and lower profile than the Diodes part. These dimensions are within standard SMD assembly tolerances and do not present placement or clearance issues. The smaller footprint may provide minor PCB layout advantages in space-constrained designs.
