Scheiber 12v 10A Circuit Breaker Replacement

They used to have replacements for E-T-A 10A circuit breaker 2210-S111-N1T2-H0 but it looks like those are no longer available. 

So far I have not been able to find a drop in replacement for the groups of four breakers used on the panel so it appears I may be looking at having to replace the entire panel.
