Agilent, G3170-65015, Sideboard PCA, for gas chromatography/mass spectrometry analyzers, used with series 5975 and 5977

Agilent Sideboard PCA is a replacement printed circuit assembly associated with the electronic control hardware of Agilent 5975 and 5977 gas chromatography/mass spectrometry systems. The board forms part of the mass selective detector electronics and is supplied as an instrument repair component rather than a separate analytical module. This specific version is obsolete and has no recommended direct replacement, making exact component identification important when maintaining an installed legacy GC/MS platform. Functional compatibility depends on the instrument series, electronics revision and service documentation, not on physical connector similarity alone. A board fault can affect the ability of the mass spectrometer to communicate with or control its associated subsystems, so replacement should follow appropriate diagnostic procedures. Installation requires qualified service work, electrostatic-discharge protection and verification of instrument performance afterward. This electronic assembly has no chromatographic separation media or sample-contacting filtration function.
