8Q-38.400MAAV-T Crystal Oscillator Equivalent & Substitute Parts

Part Overview

The 8Q-38.400MAAV-T is a 38.4 MHz surface mount crystal manufactured by TXC CORPORATION. This fundamental mode crystal operates across the temperature range of -20°C to 70°C and is specified for 8pF load capacitance with 80 Ohms equivalent series resistance. The component is actively produced and maintains RoHS compliance with MSL 1 rating, indicating unlimited shelf life under standard storage conditions. Substitute parts are identified when inventory constraints, supply chain disruptions, or procurement requirements necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the 8Q-38.400MAAV-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 38.4 MHz (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• Load Capacitance: 8pF (exact match required)
• ESR: 80 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -20°C to 70°C (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 1.60mm × 1.20mm × 0.40mm maximum height (exact match required)

The substitute part C16-38.400-8-3030-M manufactured by Aker Technology USA satisfies all mandatory matching parameters and is therefore classified as a parametric equivalent. Both components are actively produced, RoHS compliant, and feature identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 8Q-38.400MAAV-T and C16-38.400-8-3030-M are active production components with full regulatory compliance. Selection between these parts should be based on the following factors:

Compliance & Certification: Both components are RoHS compliant and REACH unaffected. The C16-38.400-8-3030-M carries ROHS3 certification, representing the most current RoHS directive compliance level. Both components are classified under ECCN EAR99 and share identical HTSUS commodity codes.

Packaging Considerations: The 8Q-38.400MAAV-T packaging specification is not detailed in available documentation. The C16-38.400-8-3030-M is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. If bulk reel packaging is required for high-volume production, the C16-38.400-8-3030-M is the appropriate selection.

Inventory & Availability: Current inventory levels show 1019 pieces of the 8Q-38.400MAAV-T and 1325 pieces of the C16-38.400-8-3030-M in stock. Selection may be influenced by immediate availability requirements and supply chain lead times.

Electrical Performance: Both components deliver identical electrical performance across all specified parameters. Circuit-level performance will be equivalent when properly integrated into oscillator circuits designed for 38.4 MHz, 8pF load capacitance operation.

Frequently Asked Questions (FAQ)

Q: Can the C16-38.400-8-3030-M be used as a direct replacement for the 8Q-38.400MAAV-T in existing designs?

A: Yes. Both components are parametric equivalents with identical frequency, stability, load capacitance, ESR, operating temperature range, and package dimensions. Direct substitution is electrically and mechanically compatible.

Q: What are the critical parameters that must match for substitution?

A: The following parameters must match exactly: frequency (38.4 MHz), frequency stability (±30ppm), load capacitance (8pF), ESR (80 Ohms), operating mode (Fundamental), operating temperature range (-20°C to 70°C), package type (4-SMD, No Lead), and physical dimensions (1.60mm × 1.20mm × 0.40mm maximum height).

Q: Are there differences in RoHS compliance between these parts?

A: Both components are RoHS compliant. The C16-38.400-8-3030-M carries ROHS3 certification, which represents compliance with the most current RoHS directive revision. Both are equally suitable for applications requiring RoHS compliance.

Q: What is the difference in packaging between these two parts?

A: The C16-38.400-8-3030-M is supplied in Tape & Reel (TR) format, standard for automated surface mount assembly. The 8Q-38.400MAAV-T packaging format is not specified in available documentation.

Q: Do these crystals require different circuit design considerations?

A: No. Both crystals operate in Fundamental mode with identical electrical specifications. Oscillator circuits designed for one component will function identically with the other when load capacitance and ESR values are properly matched in the circuit design.

Q: Are there any temperature range limitations I should consider?

A: Both components operate across the identical temperature range of -20°C to 70°C. Applications requiring operation outside this range would require alternative crystal specifications.

Q: What is the MSL rating and why does it matter?

A: Both components carry MSL 1 rating, indicating unlimited shelf life under standard storage conditions. This eliminates moisture sensitivity concerns and simplifies inventory management and storage requirements.
