Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4430.1403 is determined by strict parametric matching across all critical electrical and mechanical specifications. The substitute part 4430.3644 qualifies as a parametric equivalent based on identical alignment in the following key parameters:

• Current Rating: 10A (exact match)
• Voltage Rating - AC: 240V (exact match)
• Voltage Rating - DC: 60V (exact match)
• Breaker Type: Thermal (exact match)
• Mounting Type: Panel Mount (exact match)
• Actuator Type: Rocker (exact match)
• Number of Poles: 2 (exact match)
• Illumination: Red (exact match)
• Illumination Voltage: 220V nominal (exact match)
• Series: TA45 (exact match)
• Approval Agencies: Identical certifications (exact match)
• RoHS and REACH Compliance: Identical status (exact match)

Both parts are manufactured by SCHURTER Inc. and maintain active product status. No deviations exist in electrical performance, mechanical interface, or regulatory compliance between the main part and its substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 4430.1403 and 4430.3644 maintain active product status and carry identical regulatory certifications across CSA, EN, GB, IEC, and UL standards. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and safety requirements. The parametric equivalence across all electrical ratings, mechanical interfaces, and functional specifications establishes these parts as direct substitutes within the TA45 series. Selection between these part numbers may be based on inventory availability, lead time, or procurement source without compromising electrical performance or regulatory compliance.
