Substitute Part Grouping Explanation

Substitute parts for the 2-2158000-7 are identified based on electrical and mechanical parameter equivalence. The substitution criteria include identical coil voltage (12VDC), matching contact form (SPDT), equivalent current rating (16A), identical switching voltage capability (400VAC maximum), and matching through-hole PC pin termination. Additional qualifying parameters include coil current (33.3 mA), coil resistance (360 Ohms), operating temperature range (-40°C to 85°C), contact material composition (Silver Tin Oxide), and timing characteristics (8 ms operate, 6 ms release). Compliance certifications including ROHS3 status and moisture sensitivity level must align. Parts meeting all these criteria are classified as parametric equivalents suitable for direct substitution in applications designed for the original component.
