Tested:

use Test::More tests => 2;

use strict;

sub splitCommaNotQuote {
    my ( $line ) = @_;

    my @fields = ();

    while ( $line =~ m/((\")([^\"]*)\"|[^,]*)(,|$)/g ) {
        if ( $2 ) {
            push( @fields, $3 );
        } else {
            push( @fields, $1 );
        }
        last if ( ! $4 );
    }

    return( @fields );
}

is_deeply(
    +[splitCommaNotQuote('S,"D" REL VALVE ASSY,000771881,')],
    +['S', '"D" REL VALVE ASSY', '000771881', ''],
    "Quote in value"
);
is_deeply(
    +[splitCommaNotQuote('S,"BELT V,FAN",000324244,')],
    +['S', 'BELT V,FAN', '000324244', ''],
    "Strip quotes from entire value"
);
