James, My company is also having problems with Spectrum Control, only in the PI filtered D-SUB connectors, all pin counts. They are having capacity problems at the factory and there is no relief in sight. There is no real equivalent to these connectors when you consider insertion loss over the entire bandwidth. We have been re-qualifying other connector vendors with trips to the test lab (expensive). We repeat radiated emissions and the immunity tests on the I/O ports where the connector is used. In some cases we have been able to eliminate the need of the connector by moving the filter function to discrete components on the PCB's (still requires re-test).
Hope this helps a little. -doug ================================= Douglas E. Powell Regulatory Compliance Engineer Advanced Energy Industries, Inc. 1625 Sharp Point Dr. Ft.

I am looking for an equivalent to a connector from Spectrum Control part number 93538-1. This is a shielded 8 position modular phone jack with a capacitive filter of 110 pf at 710VDC on each pin. It was formerly Amp part number 93538-1 before Spectrum Control bought the rights. Any one out there have an idea of who might make an equivalent?
