What receptacles can be used for more than 1 series?

The receptacle of the HPT-series: HPTR34Z ; can be used for both the HPT-series as the MPTEG-series

These two series are mixed by several motorsport companies such as Hyundai.

Another example of mixed receptacles is the flat receptacle of the MHS-series: MHSRF33Z MHSRF33S MHSRFWB MHSRFWZ . These receptacles can also be used for the HGR series. However, the receptacles specific to the HGR-series can't be used by the MHS series. The reason for this is that the CROSS PIN of the MHS series is too small to be used on HGR-receptacles.
