Published cross-references list it alongside the TMS4116 (Texas Instruments), MK4116 (Mostek), MCM4116 (Motorola), AM9016 (AMD), and MB8116 (Fujitsu). Speed grade, supply voltages, and timing must match your equipment — always compare datasheets before substituting a different manufacturer's part or speed grade.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQ\u0026amp;A\u003c\/strong\u003e\u003cbr\u003eQ: What is the NEC μPD416D-2? A: A 16K x 1 (16,384 x 1-bit) dynamic NMOS RAM with a 200 ns access time in a 16-pin ceramic DIP package.\u003cbr\u003eQ: Is the μPD416 compatible with the 4116? A: The μPD416 is listed in published 4116-family cross-references alongside the TMS4116, MK4116, and MB8116. Confirm speed grade and your equipment's supply voltages before installing.\u003cbr\u003eQ: Why is this chip discontinued? A: NEC spun off its semiconductor business as NEC Electronics in 2002, which merged into Renesas Electronics in 2010, and 16K NMOS DRAMs were superseded by higher-density memory.
