The 4RCD0124KC0ATG is a DDR4 register from the 4RCD family, designed to buffer command, address, and control signals on a DDR4 memory module. The part carries no internal PLL, so the input clock must be supplied at the desired frequency — the register simply buffers and re-drives it.
It is ROHS3 compliant.
No direct equivalent replacement is listed in the record. The peer parts (9DBL411BGLFT, 9ZXL0851EKKLF, 9ZXL1231EKILF) serve different functions — clock buffers for PCIe/QPI — not DDR4 registers. For a DDR4 register, stick with the 4RCD0124KC0ATG or check the manufacturer's cross-reference guide.
The record does not specify a maximum DDR4 speed grade. As a DDR4 register, it is designed for the DDR4 interface standard and should support common data rates including DDR4-2666, but verify the exact timing parameters from the full datasheet.
