Substitute Part Grouping Explanation

Substitution eligibility for the AV-37.050MAGV-T is determined by strict equivalence across the following critical parameters:

Frequency Specification: The substitute part must operate at 37.05 MHz. This frequency is the primary functional requirement and cannot be altered.

Frequency Tolerance and Stability: The substitute must maintain ±30ppm frequency tolerance and ±50ppm frequency stability to ensure circuit performance within design specifications.

Load Capacitance: The substitute must have 8pF load capacitance to maintain compatibility with oscillator circuit design and tuning networks.

Equivalent Series Resistance (ESR): The substitute must have 60 Ohms ESR to ensure proper circuit impedance matching and oscillation characteristics.

Operating Mode: The substitute must operate in Fundamental mode, consistent with the primary part.

Temperature Range: The substitute must support the -40°C to 85°C operating temperature range.

Package Configuration: The substitute must use 4-SMD, No Lead packaging with dimensions of 3.20mm x 2.50mm and maximum seated height of 0.90mm to ensure PCB footprint compatibility.

Compliance Standards: The substitute must maintain AEC-Q200 rating and RoHS compliance status.

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The AV-37.050MAGV-T manufactured by FTS is a direct parametric equivalent to the TXC CORPORATION AV-37.050MAGV-T. Both parts are active products with identical electrical specifications, mechanical dimensions, and compliance certifications.

Selection Criteria Based on Provided Data:

Both parts maintain AEC-Q200 automotive-grade qualification, indicating suitability for applications requiring automotive-level reliability. Both parts are RoHS compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, eliminating moisture-related handling constraints.

The FTS variant currently has higher inventory availability (3623 Pcs) compared to the TXC CORPORATION variant (1096 Pcs), which may influence procurement decisions based on supply chain requirements.

Both parts are packaged in Tape & Reel (TR) format, suitable for automated assembly processes.

Selection between these two equivalent parts should be based on procurement lead time, inventory availability, cost considerations, and established supplier relationships, as all technical and compliance parameters are identical.

Frequently Asked Questions (FAQ)

Q: Can the FTS AV-37.050MAGV-T be used as a direct replacement for the TXC CORPORATION AV-37.050MAGV-T?

A: Yes. Both parts are parametric equivalents with identical frequency specifications (37.05 MHz), frequency tolerance (±30ppm), load capacitance (8pF), ESR (60 Ohms), operating temperature range (-40°C to 85°C), package configuration (4-SMD, No Lead, 3.20mm x 2.50mm), and compliance ratings (AEC-Q200, RoHS Compliant). Direct substitution is supported.

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

A: No. Both parts use identical 4-SMD, No Lead packaging with dimensions of 3.20mm x 2.50mm and maximum seated height of 0.90mm. PCB footprint compatibility is guaranteed.

Q: What does the ±30ppm frequency tolerance specification mean?

A: Frequency tolerance of ±30ppm indicates that the actual operating frequency will not deviate more than 30 parts per million from the nominal 37.05 MHz specification. At 37.05 MHz, this represents a tolerance band of approximately ±1.1115 kHz.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 qualification, which is the automotive-grade reliability standard. This rating indicates suitability for automotive and other high-reliability applications.

Q: What is the significance of MSL Level 1 (Unlimited) moisture sensitivity?

A: MSL Level 1 (Unlimited) indicates that the component has no moisture sensitivity limitations. Standard moisture-sensitive device (MSD) handling procedures and dry-pack storage are not required. The part can be stored and handled under standard industrial conditions.

Q: Can these crystals be used interchangeably in the same circuit design?

A: Yes. The identical electrical parameters, load capacitance, ESR, and operating temperature range ensure that both parts will function identically within the same circuit design without requiring circuit modifications or re-tuning.

Q: What is the difference between frequency tolerance and frequency stability?

A: Frequency tolerance (±30ppm) specifies the initial accuracy of the crystal frequency at the time of manufacture. Frequency stability (±50ppm) specifies the maximum frequency variation over the operating temperature range (-40°C to 85°C) and over the component's operational lifetime.
