Compatibility & sourcing notes
The W6100 is a pin-compatible upgrade of the W5100S — same hardwired TCP/IP architecture plus IPv4/IPv6 dual-stack. Check the new registers if you enable IPv6 features.
The two share a footprint and interface and can usually be swapped directly; before mass production, still confirm voltage, density, and timing against both datasheets.
