Hello, I ordered some I.C.'s from a supplier of obsolete parts. These are PKD01EY peak detectors. The date code is 0729. The product identification is white epoxy paint. I have never seen CerDIP painted. They are always laser etched. I also use a lot of CerDIP AD698SQ chips. They are also laser etched. On the underside of the painted PKD01EY chips, there is no country of origin. Are these painted PKD01EY chips fake/phony ???  Please Help
