FAQ
Q1: Can Suzhou Hangjing's Frequency Crystal 8.0 x 3.8 FR08S4 series be a pin-to-pin replacement for any other brands/models? Does it offer a price advantage?
A: Yes, our crystal offers direct pin-to-pin compatibility with Epson's MC-306, ensuring seamless integration into existing designs. While providing a competitive cost advantage, final pricing may vary based on specific parameters.
Q2: Can it replace smaller crystal packages (e.g., 3.2×2.5mm)?
A: Our tuning fork – FR08S4 cannot serve as a direct replacement due to its larger 8.0×3.8mm footprint. If a smaller size is required, we recommend Suzhou Hangjing's FC31M2 series (3.2×2.5mm) or other compact alternatives from different brands. However, PCB redesign would be necessary due to the size difference.
Q3: What is the SPQ for your Frequency Crystal 8.0 x 3.8 – FR08S4 series?
A: The standard packaging is 3,000pcs per reel. For sample-stage orders, we can support MOQ 20pcs upon request.
Q4: Do you keep stock? If re-production is needed, what is the lead time?
A: We keep standard items in stock for immediate shipment. For high-volume production orders, typical lead times are 4–6 weeks to ensure quality manufacturing.
