the old out dated relay pt#.. specs will be listed in some old PAPER catalog
what they are saying is NO cross reference
you said "COIL"
the pt# you reference lists as a complete relay in this PDF
http://www.stancor.com/pdfs/Catalog_2006/index2k5cat.pdfask them for the specs, contact rating, duty rating,
for this relay
i think you will be able to use it, as long as the contacts are 100amps or more
and its continuous duty
a coil is only part of a relay, and a "COIL" with a similar pt# , could be for an entirely different device
