Electrically equivalent to LM78M12, L78M12, and MC78M12 parts; those are commonly TO-220, so check fit and mounting before substituting a different package.\u003cbr\u003e\u003cbr\u003eQ\u0026amp;A\u003cbr\u003eQ: What is the LM341P12?\u003cbr\u003eA: A National Semiconductor 12V, 500mA three-terminal positive voltage regulator in a TO-202 package.\u003cbr\u003e\u003cbr\u003eQ: Is the LM341 the same as the 78M12?\u003cbr\u003eA: Yes, functionally. National's datasheet covers the LM341 and LM78MXX series together, and this part is marked with both numbers.\u003cbr\u003eQ: Can a 7812 replace a 78M12?\u003cbr\u003eA: A 7812 is rated for higher current, so it can usually substitute electrically, but the package and mounting may differ.\u003cbr\u003e\u003cbr\u003eDISCLAIMER\u003cbr\u003eItem is new old stock, sold as pictured.
