Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 4430.2133 are classified based on strict parametric equivalence. All substitute parts maintain identical electrical specifications: 12A current rating, 240V AC and 60V DC voltage ratings, thermal breaker type, rocker actuator, 2-pole configuration, and panel mount design. The primary substitution criterion is the matching of these core electrical and mechanical parameters across all listed alternatives.

The substitute parts are grouped into two categories:

TA45 Series Equivalents (Primary Substitutes): Parts 4430.0024, 4430.1034, 4430.1637, 4430.242, 4430.2693, 4430.3041, 4430.3223, and 4430.3263 maintain identical series designation and all electrical/mechanical specifications. These parts are fully interchangeable with the main part number 4430.2133.

TA35 Series Equivalents (Cross-Series Substitutes): Parts 4435.0092 and 4435.0223 belong to the TA35 series but maintain all identical electrical specifications (12A, 240V AC, 60V DC, thermal, rocker, 2-pole, panel mount). These represent cross-series alternatives with equivalent performance characteristics.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance. The TA45 series substitutes (4430.0024, 4430.1034, 4430.1637, 4430.242, 4430.2693, 4430.3041, 4430.3223, 4430.3263) are direct series equivalents with identical certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 approval. These parts are fully compatible for direct replacement applications.

The TA35 series substitutes (4435.0092, 4435.0223) provide equivalent electrical performance with identical current, voltage, and mechanical specifications. While series designation differs, electrical and mechanical parameters remain unchanged. Both TA35 alternatives maintain ROHS3 compliance and Active status.

Selection between TA45 and TA35 series alternatives depends on existing design specifications and mechanical envelope requirements. All parts are manufactured by SCHURTER Inc. and packaged in bulk format. Inventory availability varies across part numbers, with 4430.242 offering the highest stock level at 1168 pieces.
