50-Position Hybrid Signal/Power Edge-Card Connector for CRPS Server PSUs
The Amphenol EnergyEdge™ X-treme HPG36P14SRT051T-02 is a female edge-card connector designed for the CRPS (Common Redundant Power Supply) form factor, carrying 50 positions split as 14 signal contacts and 36 power contacts. This hybrid contact count lets a single connector handle both the low-current control/signalling lines and the main DC power bus from the PSU to the backplane, reducing the number of separate connectors needed on the power-supply card edge. Gold at this thickness is rated for the frequent mate/unmate duty of a field-replaceable PSU; tin or thinner gold would fret through sooner.
How It Compares: 50-Position Hybrid vs 64-Position Power-Only Sibling
The critical difference is the contact assignment: the HPG36P14SRT051T-02 dedicates 14 positions to signal contacts and 36 to power, while the 10053363-201LF allocates all 64 positions to power. If your BOM specifies a connector that carries both the PSU control lines and the DC bus on one card-edge footprint, the hybrid 50-position part is the match. If the design uses a separate signal header and only needs a power-only edge connector, the 64-position sibling is an option — but the footprint and card-edge pad layout differ, so they are not drop-in interchangeable.
