Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7V-38.400MAHV-T are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes (Series Change Only): Parts that maintain identical electrical specifications and package dimensions while differing only in manufacturer series designation or minor physical variations that do not affect PCB integration.

Similar Substitutes (Parameter Variance): Parts that maintain the core frequency and operating temperature range but exhibit variations in load capacitance, ESR, package dimensions, or physical height. These parts require circuit-level verification of compatibility with the oscillator load network.

The substitution logic is determined by the following critical parameters:

• Frequency: 38.4 MHz (non-negotiable)
• Frequency Stability: ±30ppm (non-negotiable)
• Operating Temperature: -40°C to 85°C (non-negotiable)
• Load Capacitance: 8pF (primary variance point)
• ESR: 60-80 Ohms (acceptable range)
• Package: 4-SMD, No Lead (preferred for footprint compatibility)
• RoHS Compliance: Required

Parameter Comparison

Engineering Selection Recommendations

7M-38.400MAHV-T (Direct Substitute): This part is the primary equivalent for the 7V-38.400MAHV-T. Both components are manufactured by TXC CORPORATION with identical electrical specifications (38.4 MHz, ±30ppm, 8pF load capacitance, 60 Ohms ESR) and package configuration (4-SMD, No Lead). The 7M series differs only in maximum seated height (0.80mm versus 0.90mm), which represents a favorable reduction in vertical profile. Both parts maintain RoHS Compliance and MSL Level 1 rating. The 7M-38.400MAHV-T is available in higher inventory (6838 pcs) compared to the main part (727 pcs), making it the preferred direct replacement when supply continuity is a consideration.

XZAEELNANF-38.400000 (Similar Substitute - Taitien): This Taitien crystal maintains the 38.4 MHz frequency and ±30ppm stability with identical 8pF load capacitance. The ESR specification increases to 80 Ohms, which is within acceptable tolerance for most oscillator circuits but requires verification against the specific load network design. The package dimensions are significantly smaller (2.05mm × 1.65mm versus 3.20mm × 2.50mm) with reduced height (0.55mm), enabling use in space-constrained applications. ROHS3 Compliance is maintained. Packaging is supplied as Cut Tape (CT) rather than Tape & Reel (TR). This part is suitable for designs where the 80 Ohm ESR specification is compatible with the oscillator circuit.

XZLEELNANF-38.400000 (Similar Substitute - Taitien): This Taitien crystal operates at 38.4 MHz with ±30ppm stability but specifies 6pF load capacitance instead of 8pF. The ESR is 80 Ohms. The reduced load capacitance requires circuit-level compatibility verification with the oscillator load network, as this parameter directly affects frequency tuning and startup characteristics. Physical dimensions match XZAEELNANF-38.400000 (2.05mm × 1.65mm, 0.55mm height). ROHS3 Compliance and MSL Level 1 rating are maintained. This part is applicable only when the oscillator circuit is designed or verified to operate with 6pF load capacitance.

Frequently Asked Questions (FAQ)

Q: Can the 7M-38.400MAHV-T be used as a direct replacement for the 7V-38.400MAHV-T without circuit modification?

A: Yes. The 7M-38.400MAHV-T maintains identical electrical specifications (frequency, stability, load capacitance, and ESR) and package configuration. The only difference is a 0.10mm reduction in maximum seated height (0.80mm versus 0.90mm), which does not affect electrical performance or PCB assembly compatibility.

Q: What is the significance of the ESR difference between the main part (60 Ohms) and the Taitien substitutes (80 Ohms)?

A: ESR affects oscillator startup behavior and power consumption. The 20 Ohm increase in ESR for Taitien parts may require verification against the specific oscillator circuit design. Most modern oscillator circuits tolerate ESR variations within this range, but confirmation with circuit simulation or testing is necessary for critical applications.

Q: Can XZLEELNANF-38.400000 be used if the circuit requires 8pF load capacitance?

A: No. XZLEELNANF-38.400000 specifies 6pF load capacitance, which differs from the 8pF requirement. Load capacitance directly affects the oscillator's frequency tuning network. Using a 6pF crystal in an 8pF-designed circuit will result in frequency deviation and potential instability. This part is only suitable for circuits specifically designed for 6pF load capacitance.

Q: What are the packaging differences between the main part and substitute options?

A: The 7V-38.400MAHV-T and 7M-38.400MAHV-T are supplied in Tape & Reel (TR) packaging for automated assembly. The Taitien parts (XZAEELNANF-38.400000 and XZLEELNANF-38.400000) are supplied in Cut Tape (CT) packaging, which may require different handling and placement equipment. TR packaging is preferred for high-volume production; CT packaging is suitable for lower-volume or manual assembly operations.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 7V-38.400MAHV-T and 7M-38.400MAHV-T carry RoHS Compliance certification. The Taitien parts carry ROHS3 Compliance certification. Both certifications meet current regulatory requirements for lead-free and restricted substance compliance.

Q: What is the physical size advantage of the Taitien crystals?

A: The Taitien parts (XZAEELNANF-38.400000 and XZLEELNANF-38.400000) measure 2.05mm × 1.65mm with 0.55mm maximum height, compared to the TXC parts at 3.20mm × 2.50mm with 0.80-0.90mm height. This represents approximately 60% reduction in footprint area and 35-40% reduction in height, enabling use in compact or space-constrained PCB designs.

Q: Which substitute part should be selected for maximum supply availability?

A: The 7M-38.400MAHV-T offers the highest inventory (6838 pcs) with identical electrical and mechanical specifications to the main part. This part is recommended when supply continuity and long-term availability are primary considerations.
