The junior AFCON is scheduled to take place in Ivory Coast from 26 April to 18 May, with this period coinciding with the business end of the Premier Soccer League season.
Getting some key players could be a challenge, but Mdaka appears optimistic.
"We have already done engagements with SuperSport [United], Cape Town City, Stellenbosch FC, and we've sat down and discussed with a lot of teams," said Mdaka.
"And they promised, but as much as they may be having challenges here and there, from where we stand, there is still that positive agreement to say we will get the players."
Reports from West Africa have since emerged that the Ivorians have withdrawn as hosts of the tournament, with CAF yet to release any official word thereon.
Meanwhile, with the bulk of the SA U20 squad already playing top flight football in the country, and the prospect of potentially catching the eyes of big European club scouts, Mdaka says clubs fully understand the dynamics and economics of the game.
"I would love it to be that way for all the teams because sometimes it's not all about their teams where they are, but it's about the individual [and their future]," he added.
"SuperSport prides itself now over Shandre [Campbell, who joined Club Brugge in Belgium], and there was never a time when we wanted Shandre and couldn't get him.
"So we might not be seeing the business behind it, but their business is also based on the development of players, so for them to see their players playing in the national team at AFCON, it's also a point for the team.
"It's an encouragement to say even their junior players left behind know this is the pathway, and I think it benefits both the country and the clubs and individuals."
