FAQ
Q1: What is the product life-cycle of the HC-49U MHz Crystals X49UT2 Series? How much advance notice will customers receive before discontinuation?
A: This product has an extended life-cycle with ongoing production. Customers will receive at least 6 months' advance notice prior to any discontinuation. Currently, there are no planned EOL (End-of-Life) notifications – it remains in stable supply status.
Q2: What is the lowest frequency point available for Hangjing's X49UT2 Series? Which frequency points are most commonly shipped?
A: The series supports frequencies as low as 1.8432MHz. High-volume shipment frequencies include:
6MHz, 4MHz, 3.072MHz, 3.2MHz, 2.4576MHz, 12MHz (common low-frequency options).
Q3: How does the HC-49U MHz Crystal compare in cost-performance?
A: As a legacy product primarily used in niche legacy projects overseas, its volume demand continues to decline due to replacement by compact SMDs (e.g., 3225). While less competitive versus newer solutions, we guarantee ongoing stable supply and support custom designs (special frequencies, pin configurations, etc.) for specialized needs.
