FAQ
Q1: Is Suzhou Hangjing's X49ST2 series compatible with standard 49S package PCB designs?
A: Yes, it is fully compatible with traditional 49S ceramic base packages (2.5mm height) and can directly replace similar products without modifying PCB layouts.
Q2: What packaging is available?
A: We support bulk packaging in vinyl bags and boxes.
QTY per bag: 100pcs MAX.
QTY per box: 1,000pcs MAX.
Optional T&R: 1,000pcs / reel
Q3: Can it replace Epson/NDK brand 49S crystals?
A: It is compatible with same-specification models (e.g., frequency, load capacitance, and temperature range). Circuit performance validation is recommended to ensure stability.
Q4: Can special frequencies be customized?
A: Yes, we support frequency customization. Please contact us with your specific requirements for feasibility assessment and quotation.
