Key Parameters

Substitute Part Grouping Explanation

Substitution of the FH3740013Z is permissible when the alternative component maintains the following critical parameters:

• Frequency: 37.4 MHz (exact match required)
• Frequency Stability: ±10ppm (exact match required)
• Load Capacitance: 8pF (exact match required)
• Operating Temperature Range: -30°C ~ 85°C (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Operating Mode: Fundamental (exact match required)
• Mounting Type: Surface Mount (exact match required)

The ESR parameter may vary within acceptable limits for the application circuit design. Physical dimensions may differ slightly while maintaining the same package classification. Substitute parts must maintain Active product status and comply with RoHS and REACH regulations.

Parameter Comparison

Engineering Selection Recommendations

Both the FH3740013Z and 8Y37470007 maintain Active product status and comply with RoHS and REACH regulatory requirements. The primary distinction between these components is the ESR specification: the FH3740013Z operates at 10 Ohms while the 8Y37470007 operates at 80 Ohms. This difference must be evaluated against the specific circuit design requirements, as ESR directly affects oscillator startup characteristics and frequency stability under load conditions. Both components share identical frequency, stability, load capacitance, operating temperature range, and package specifications, making them functionally equivalent from a timing perspective when circuit design accommodates the ESR variance. Physical dimensions differ slightly, with the 8Y37470007 being more compact in both length and height while maintaining the same 4-SMD, No Lead package classification.

Frequently Asked Questions (FAQ)

Q: Can the 8Y37470007 directly replace the FH3740013Z in all applications?

A: Direct substitution is permissible when the circuit design accommodates the ESR difference of 70 Ohms. The higher ESR of the 8Y37470007 may affect oscillator startup time and frequency stability margins. Circuit simulation or testing is necessary to confirm compatibility with specific application requirements.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: Both components use the 4-SMD, No Lead package classification. The 8Y37470007 is physically smaller in length and height. PCB layout and component placement must accommodate the dimensional variance. Footprint compatibility should be verified before implementation.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both components comply with RoHS and REACH regulations. The FH3740013Z carries ROHS3 Compliant status while the 8Y37470007 carries RoHS Compliant status. Both maintain MSL 1 (Unlimited) moisture sensitivity classification, indicating equivalent handling and storage requirements.

Q: What is the significance of the frequency stability specification?

A: Both components specify ±10ppm frequency stability, which defines the maximum frequency deviation over the operating temperature range and under specified load conditions. This parameter is critical for timing-sensitive applications and must remain constant for substitution validity.

Q: How does ESR affect crystal oscillator performance?

A: ESR influences the energy required to sustain oscillation and affects frequency stability under varying load conditions. The 10 Ohm ESR of the FH3740013Z provides lower impedance characteristics compared to the 80 Ohm ESR of the 8Y37470007. Application circuits must be designed to accommodate the specific ESR value of the selected component.
