Magnetic and Mossbauer measurements were performed for Mn2.xFexP0.5As0.5, 0.5 less-than or equal to x less-than or equal to 1.0. It was shown that with decreasing Fe content magnetic interaction significantly weakens. Low temperature magnetic structure could be explained as a superposition of ferromagnetic and antiferromagnetic contributions to the whole magnetic moment of the alloy.
