Parameter Comparison

Engineering Selection Recommendations

Both the 8Z-20.000MEEV-T and QT252S-20.000MEEV-T are active production components with identical electrical and mechanical specifications. Selection between these parts may be based on:

Inventory Availability: The QT252S-20.000MEEV-T (QST) currently has 1151 pieces in stock compared to 947 pieces for the 8Z-20.000MEEV-T (TXC).

Compliance Status: The QT252S-20.000MEEV-T carries RoHS3 compliance certification and Moisture Sensitivity Level (MSL) 1 rating, indicating unlimited shelf life under standard storage conditions.

Supply Chain Considerations: Both components share identical HTSUS classification (8541.60.0050) and ECCN designation (EAR99), ensuring equivalent regulatory treatment in procurement and logistics.

Frequently Asked Questions (FAQ)

Q: Can the QT252S-20.000MEEV-T be used as a direct replacement for the 8Z-20.000MEEV-T?

A: Yes. The QT252S-20.000MEEV-T meets all electrical, mechanical, and environmental specifications of the 8Z-20.000MEEV-T. Both components operate at 20 MHz with ±10ppm stability, 8pF load capacitance, 100 Ohms ESR, and are housed in identical 2.50mm x 2.00mm 4-SMD packages.

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

A: No. Both components have identical physical dimensions of 2.50mm length x 2.00mm width with a maximum seated height of 0.55mm. Both use 4-SMD, No Lead packaging and are supplied in Tape & Reel format.

Q: What is the significance of the MSL 1 rating on the QT252S-20.000MEEV-T?

A: MSL 1 indicates Moisture Sensitivity Level 1, which means the component has unlimited shelf life under standard storage conditions (typically 30°C / 85% RH). This eliminates time-based storage constraints for inventory management.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the 8Z-20.000MEEV-T and QT252S-20.000MEEV-T operate from -20°C to 70°C, ensuring equivalent thermal performance in target applications.

Q: Are there any regulatory or compliance differences between these parts?

A: Both components share identical HTSUS classification and ECCN designation. The QT252S-20.000MEEV-T carries additional RoHS3 compliance certification, which may be relevant for specific procurement requirements.
