PIN-TO-PIN ALTERNATIVE
X503227MSB4SI is a Chinese-manufactured pin-to-pin drop-in replacement for EPSON FA-20H / KDS 27 MHz (EPSON / KDS / TXC).
27 MHz in the standard 5032 footprint, from a domestic supplier with stock availability.
X503227MSB4SI — Alternative to EPSON FA-20H / KDS 27 MHz
X503227MSB4SI from YXC 扬兴 is supplied by JTDZ Tech (Shenzhen Jingteng Electronics) as a cost-effective, short-lead-time alternative to the imported EPSON FA-20H / KDS 27 MHz (EPSON / KDS / TXC). Chinese-sourced semiconductors have moved well beyond "cheap substitute" status: the parts below are production-validated in industrial, automotive and consumer designs, and they remove both the allocation risk and the long lead times that come with imported.

What to check before substituting X503227MSB4SI for EPSON FA-20H
- 5032 is a standard footprint, so a 27 MHz YXC part substitutes directly for EPSON FA-20H or KDS equivalents at matched load capacitance.
- Confirm the required load capacitance and tolerance grade before ordering, as the suffix determines both.
- Wide product range means 27 MHz is a stock frequency, not a custom order.
Typical Applications
- Video and imaging equipment
- Wireless communication modules
- Industrial control and instrumentation
- Consumer electronics
