Substitute Part Grouping Explanation

Substitution eligibility for the MY4Z AC200/220 (S) is determined by strict equivalence across the following critical parameters:

Contact configuration (4PDT), coil voltage (220VAC), contact current rating (3A), switching voltage limits (250VAC, 125VDC maximum), coil current draw (17 mA), socketable mounting type, 14-pin plug-in termination, operating temperature range (–55°C to 60°C), contact material composition (Silver/Gold), and coil resistance (12.95 kOhms).

The substitute part MY4Z-02-AC200/220 meets all these criteria and is classified as an active product, making it a direct parametric equivalent suitable for replacement applications.
