I'm not sure how you can tell fakes (although laser marked 1960s chips were rare!) but have bought a range of older devices to keep my menagerie of HP & Tek stuff fed and watered from an ebay seller in the UK called 'LittleDiode' with no problems so far. I see they have some CA3102E listed. No affiliation etc.....
