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.
The 4RCD0124KC0ATG is listed as Active in production. 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.
