Substitute Part Grouping Explanation

Substitution eligibility for the 8Q-25.000MAAV-T is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Frequency: 25 MHz
• Frequency Stability: ±30ppm
• Frequency Tolerance: ±30ppm
• Load Capacitance: 8pF
• ESR: 100 Ohms
• Operating Mode: Fundamental

Mechanical Parameters (Must Match Exactly):

• Package / Case: 4-SMD, No Lead
• Size / Dimension: 1.60mm × 1.20mm
• Height - Seated (Max): 0.40mm
• Mounting Type: Surface Mount

Environmental & Compliance Parameters (Must Match Exactly):

• Operating Temperature Range: -20°C to 70°C
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. No deviations in frequency, load capacitance, ESR, package dimensions, or temperature range are permitted.

Parameter Comparison

Engineering Selection Recommendations

Both the TXC CORPORATION 8Q-25.000MAAV-T and the FTS 8Q-25.000MAAV-T are Active product status components with full RoHS compliance and MSL 1 rating. Selection between these parts is based on availability, lead time, and inventory requirements rather than technical differentiation. The FTS variant currently maintains higher inventory levels (6451 Pcs) compared to the TXC variant (1119 Pcs), which may influence procurement decisions for high-volume applications. Both parts satisfy identical electrical, mechanical, and environmental specifications, ensuring direct interchangeability in circuit applications without modification to PCB layout, schematic design, or firmware parameters.

Frequently Asked Questions (FAQ)

Q: Can the FTS 8Q-25.000MAAV-T be used as a direct replacement for the TXC CORPORATION 8Q-25.000MAAV-T?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (25 MHz, ±30ppm stability, 8pF load capacitance, 100 Ohms ESR), mechanical dimensions (1.60mm × 1.20mm, 4-SMD No Lead package), and environmental ratings (-20°C to 70°C, RoHS compliant, MSL 1). No circuit modifications are required.

Q: Are there any differences in package dimensions between these two parts?

A: No. Both parts share identical package specifications: 4-SMD, No Lead configuration with 1.60mm × 1.20mm footprint and 0.40mm maximum seated height. PCB layout and land pattern designs are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TXC CORPORATION and FTS variants are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity rating. The FTS variant includes REACH status information available upon request.

Q: What is the significance of the ±30ppm frequency stability specification?

A: The ±30ppm specification defines the maximum frequency deviation across the operating temperature range (-20°C to 70°C) and over the component's operational lifetime. This parameter is identical for both substitute parts and must be matched exactly for circuit compatibility.

Q: Can these 25 MHz crystals be used in applications requiring different frequency values?

A: No. The 25 MHz frequency is a fixed specification. These crystals are designed specifically for 25 MHz applications. Different frequency requirements necessitate different crystal part numbers.

Q: What does the 8pF load capacitance specification mean for circuit design?

A: The 8pF load capacitance indicates the capacitive load the crystal oscillator circuit must present for the crystal to operate at its specified frequency and stability. Circuit design must match this load capacitance value. Both substitute parts require identical load capacitance implementation.

Q: Are there inventory or lead time considerations when selecting between these substitutes?

A: Yes. The FTS variant currently has 6451 Pcs in stock compared to 1119 Pcs for the TXC CORPORATION variant. For applications with extended lead time requirements or high-volume production, the FTS option may provide better availability.
