SSRneon G2 some parts Substitutions

[vladakru]

what u think for BTA08-600B (http://www.mikroprinc.com/index.php?page=shop.getfile&file_id=5122&product_id=3733&option=com_virtuemart&Itemid=8) instead of BTA04-700T...?
and MOC3021 (http://www.mikroprinc.com/index.php?page=shop.getfile&file_id=6384&product_id=5058&option=com_virtuemart&Itemid=8) instead of MOC3023 current gate is 15mA whether it would work with the replacement resistor ...?

[P. Short]

Changing to the MOC3021 and new gate resistor value would most likely overload the power or ground pins of whatever microcontroller (and possibly power supply circuit) that is used to control the SSR. You're much better off staying with the original parts list.
