Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 8Y-38.400MAHV-T is based on the following critical parameters that must remain constant across all equivalent parts:

Mandatory Matching Parameters:

• Frequency: 38.4 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)
• Package / Case: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)

Allowable Variation Parameters:

• Load Capacitance: 8pF (primary specification) or 6pF (acceptable with circuit verification)
• ESR: 80 Ohms (primary specification) or 150 Ohms (acceptable with oscillator design review)
• Physical Dimensions: Minor variations within SMD tolerance ranges
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) - both acceptable for surface mount assembly
• RoHS Status: RoHS Compliant or ROHS3 Compliant - both acceptable

The three identified substitute parts (XZAEELNANF-38.400000, X3AEELNANF-38.400000, XZLEELNANF-38.400000) all manufactured by Taitien meet the mandatory matching criteria. Variations in ESR and load capacitance require engineering evaluation based on specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: XZAEELNANF-38.400000 (Taitien)

This part provides direct electrical equivalence to the 8Y-38.400MAHV-T with identical load capacitance (8pF) and ESR (80 Ohms). All critical parameters match exactly. Physical dimensions show minimal variation (2.05mm x 1.65mm versus 2.00mm x 1.60mm), which remains within standard SMD tolerance ranges. ROHS3 compliance exceeds RoHS requirements. This substitute is suitable for direct replacement in applications where the original TXC part is unavailable.

Secondary Substitute: X3AEELNANF-38.400000 (Taitien)

This part matches all critical electrical parameters but features elevated ESR at 150 Ohms compared to the primary specification of 80 Ohms. The smaller physical footprint (1.60mm x 1.20mm) and reduced height (0.45mm) may provide PCB layout advantages in space-constrained designs. Selection of this part requires oscillator circuit analysis to confirm startup margin and frequency stability with the higher ESR value. ROHS3 compliance and unlimited MSL rating are maintained.

Tertiary Substitute: XZLEELNANF-38.400000 (Taitien)

This part differs in load capacitance specification (6pF versus 8pF primary). While frequency, stability, and operating mode remain identical, the reduced load capacitance requires circuit design verification. ESR matches the primary specification at 80 Ohms. Physical dimensions and height match XZAEELNANF-38.400000. This substitute is applicable only when the target circuit is designed for 6pF load capacitance operation.

All three substitute parts maintain Active product status, REACH Unaffected designation, and EAR99 ECCN classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 8Y-38.400MAHV-T with any of the Taitien alternatives without circuit modification?

A: XZAEELNANF-38.400000 provides direct substitution with identical electrical specifications (8pF load capacitance, 80 Ohms ESR). X3AEELNANF-38.400000 and XZLEELNANF-38.400000 require circuit evaluation due to ESR and load capacitance variations respectively.

Q: What is the impact of ESR difference between 80 Ohms and 150 Ohms?

A: ESR affects oscillator startup behavior and power consumption. The 150 Ohms ESR in X3AEELNANF-38.400000 requires verification that the oscillator circuit provides sufficient drive capability. This determination depends on specific circuit design parameters not provided in this reference.

Q: Does the physical size difference between parts affect PCB compatibility?

A: The 8Y-38.400MAHV-T measures 2.00mm x 1.60mm. XZAEELNANF-38.400000 and XZLEELNANF-38.400000 measure 2.05mm x 1.65mm (within standard SMD tolerance). X3AEELNANF-38.400000 measures 1.60mm x 1.20mm (smaller footprint). Verify PCB footprint design specifications before selecting the smaller alternative.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original part is RoHS Compliant. All three substitute parts are ROHS3 Compliant, which exceeds RoHS requirements and maintains regulatory compliance.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: The original 8Y-38.400MAHV-T is supplied in Tape & Reel (TR) format for automated assembly. All substitute parts are supplied in Cut Tape (CT) format. Both formats are compatible with standard surface mount assembly processes. Verify your procurement and assembly workflow requirements.

Q: Can I use XZLEELNANF-38.400000 with 6pF load capacitance in a circuit designed for 8pF?

A: No. Load capacitance is a critical parameter that affects oscillation frequency and stability. Use XZLEELNANF-38.400000 only in circuits specifically designed for 6pF load capacitance operation.

Q: What is MSL 1 (Unlimited) and why does it matter?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All parts in this reference maintain this specification, simplifying inventory management.

Q: Are there any REACH or ECCN restrictions on these parts?

A: All parts listed are REACH Unaffected and classified as EAR99. No special export licensing or regulatory restrictions apply beyond standard component handling requirements.
