Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 8Z38420001 crystal is determined by strict equivalence across the following critical parameters:

Frequency Specification: The substitute part must operate at 38.4 MHz with identical frequency stability of ±30ppm to ensure circuit timing accuracy and system synchronization.

Load Capacitance: The 12pF load capacitance requirement must be matched exactly to maintain oscillation characteristics and circuit compatibility.

Equivalent Series Resistance (ESR): The 60 Ohms ESR specification must be preserved to ensure proper circuit damping and startup behavior.

Operating Mode: Fundamental mode operation is required; no overtone or harmonic variants are acceptable.

Temperature Range: The operating temperature range of -20°C to 70°C must be supported without deviation.

Package Configuration: The 4-SMD, No Lead surface mount package with dimensions 2.50mm x 2.00mm and maximum seated height of 0.55mm must be maintained for PCB layout compatibility.

Compliance Standards: RoHS Compliance and MSL 1 (Unlimited) rating must be retained.

The substitute part 8Z-38.400MAAE-T meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 8Z38420001 and 8Z-38.400MAAE-T are active products manufactured by TXC CORPORATION with full RoHS Compliance and MSL 1 (Unlimited) certification. The primary distinction between these parts is packaging format: the 8Z38420001 is supplied in standard packaging, while the 8Z-38.400MAAE-T is available in Cut Tape (CT) format.

Selection between these equivalent parts should be based on procurement requirements and supply chain logistics. The 8Z-38.400MAAE-T currently maintains higher inventory availability (5846 Pcs) compared to the 8Z38420001 (1167 Pcs), which may influence lead time and bulk order fulfillment. Both parts carry identical electrical and mechanical specifications, ensuring direct functional interchangeability in circuit applications.

For applications requiring specific packaging formats or inventory allocation, either part may be selected without modification to circuit design or PCB layout.

Frequently Asked Questions (FAQ)

Q: Can the 8Z-38.400MAAE-T be used as a direct replacement for the 8Z38420001?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (38.4 MHz, ±30ppm stability, 12pF load capacitance, 60 Ohms ESR), operating temperature range (-20°C to 70°C), and physical package dimensions (2.50mm x 2.00mm, 0.55mm max height). No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The 8Z38420001 uses standard packaging, while the 8Z-38.400MAAE-T is supplied in Cut Tape (CT) format. All electrical and mechanical parameters are identical.

Q: Are both parts RoHS Compliant?

A: Yes. Both the 8Z38420001 and 8Z-38.400MAAE-T are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Will the 8Z-38.400MAAE-T fit the same PCB footprint as the 8Z38420001?

A: Yes. Both parts use the 4-SMD, No Lead package with identical dimensions of 2.50mm x 2.00mm and maximum seated height of 0.55mm, ensuring compatibility with the same PCB layout and reflow profile.

Q: What frequency stability should I expect from either part?

A: Both parts provide ±30ppm frequency stability across the operating temperature range of -20°C to 70°C.

Q: Can these crystals be used in applications requiring higher temperature operation?

A: No. Both parts are specified for operation between -20°C and 70°C only. Applications requiring extended temperature ranges require alternative component selection.
