Substitute Part Grouping Explanation

Substitution of the 8Q-37.400MEEV-T is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Frequency: 37.4 MHz
• Frequency Stability: ±10ppm
• Frequency Tolerance: ±10ppm
• Load Capacitance: 8pF
• ESR: 80 Ohms
• Operating Mode: Fundamental

Mechanical Parameters (Must Match Exactly):

• Package / Case: 4-SMD, No Lead
• Size / Dimension: 0.063" L x 0.047" W (1.60mm x 1.20mm)
• Height - Seated (Max): 0.016" (0.40mm)
• Mounting Type: Surface Mount

Environmental & Compliance Parameters:

• Operating Temperature Range: -20°C to +70°C

Substitute parts identified in this reference maintain full parametric equivalence across all electrical, mechanical, and environmental specifications. Packaging format (Cut Tape vs. Tape & Reel) represents a logistics variation only and does not affect component functionality or compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TXC CORPORATION 8Q-37.400MEEV-T and the FTS 8Q-37.400MEEV-T are parametrically equivalent and suitable for direct substitution in applications requiring a 37.4 MHz crystal oscillator with 8pF load capacitance and ±10ppm frequency stability.

Selection Criteria Based on Provided Information:

TXC CORPORATION 8Q-37.400MEEV-T:

• Active product status with established supply chain
• Available in Cut Tape (CT) packaging format
• 2659 units in current inventory
• RoHS Compliant with MSL 1 rating

FTS 8Q-37.400MEEV-T:

• Active product status with established supply chain
• Available in Tape & Reel (TR) packaging format
• 2929 units in current inventory
• RoHS Compliant with MSL 1 rating
• REACH status available upon request

Both components meet identical electrical specifications, mechanical dimensions, and environmental operating requirements. Selection between manufacturers should be based on packaging format requirements (Cut Tape vs. Tape & Reel), supply chain preferences, and inventory availability for your specific application volume.

Frequently Asked Questions (FAQ)

Q: Can the FTS 8Q-37.400MEEV-T be used as a direct replacement for the TXC CORPORATION 8Q-37.400MEEV-T?

A: Yes. Both parts are parametrically equivalent across all electrical, mechanical, and environmental specifications. They share identical frequency (37.4 MHz), frequency stability (±10ppm), load capacitance (8pF), ESR (80 Ohms), package type (4-SMD, No Lead), physical dimensions (1.60mm x 1.20mm), and operating temperature range (-20°C to +70°C). The only difference is the packaging format (Cut Tape vs. Tape & Reel) and manufacturer.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape (CT) and Tape & Reel (TR) are logistics and handling formats only. Both formats contain the same component with identical electrical and mechanical specifications. Cut Tape is typically used for smaller quantities or manual assembly processes, while Tape & Reel is standard for automated pick-and-place assembly equipment. The component itself functions identically regardless of packaging format.

Q: Are both parts RoHS compliant?

A: Yes. Both the TXC CORPORATION and FTS versions of the 8Q-37.400MEEV-T are RoHS Compliant, meeting the Restriction of Hazardous Substances directive requirements.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. Components with MSL 1 rating have unlimited shelf life and do not require special moisture control or baking procedures prior to soldering. This simplifies handling and storage requirements.

Q: Can these crystals be used in applications requiring different operating temperatures?

A: No. Both parts are specified for operation within the -20°C to +70°C temperature range. Applications requiring extended temperature ranges require alternative components with different thermal specifications.

Q: What is the significance of the ±10ppm frequency stability specification?

A: The ±10ppm frequency stability specification indicates the maximum frequency deviation from the nominal 37.4 MHz center frequency across the operating temperature range and over the component lifetime. This specification is critical for applications requiring precise frequency control and must be matched exactly when selecting substitute components.

Q: Are there any differences in REACH compliance between the two manufacturers?

A: The TXC CORPORATION part lists REACH Status as "REACH Unaffected," while the FTS part indicates "REACH info available upon request." Both parts are suitable for use in REACH-regulated applications. Contact the FTS manufacturer directly for detailed REACH compliance documentation if required for your specific application or region.
