CA3080E equivalent sought

    I've recently been advised that the CA3080E OTA chip is being discontinued
    by a number of manufacturers due to non-compliance with OHSA regulations.
    The supplier usually indicates equivalent products within their range,
    however, on this case they have no suggestions!

    Is there a quick way to cross reference opamps and similiar to a compatible
    part? I have a datasheet for the CA3080, but Googling for equivalents is
    not being very helpful.

    What I need is either a pin-for-pin drop in replacement, or better
    still, a URL for a site that can competently provide equivalents.

    Any help would be appreciated!

    Mike.

    I think an LM13600 is a dual version though it has linearizing diodes
    and a buffer they can be ignored and it works like a dual CA3080. Of
    course not the same pinout but then you get 2 x CA3080 in a package.

    Some manufacturers have cross references online. One is NTE, but I'm sure
    I've been to others that have the same (fairchild maybe?)

    I'll check out NTE to see if they can help with a pin for pin equivalent. The
    other lead on the LM13600 backs up some other information I found, which may
    be a "plan-b" option.

    Thanks both!
