Key Parameters

Substitute Part Grouping Explanation

Substitution is determined exclusively by matching the core electrical and mechanical parameters: filter type (Three Phase Wye), configuration (Single Stage), current rating (36 A), voltage ratings, operating frequency, mounting style (chassis mount), termination style (terminal block), application (general purpose), compliance with listed approval agencies (CSA, ENEC, UR), operating temperature range, RoHS/REACH status, and relevant packaging form. Only those parts meeting or exceeding all these parameters are listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection between FN256-36-47 and FN3256H-36-33 may be guided by product status, RoHS compliance, REACH status, and certification requirements. The FN256-36-47 is obsolete, while FN3256H-36-33 is active and ROHS3 Compliant, both holding equivalent approvals (CSA, ENEC, UR) and environmental status (REACH Unaffected). Both parts offer identical mechanical mounting and termination styles within the stated temperature range.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for substitution of a three-phase line filter?
A1: Filter type, configuration, current rating, voltage ratings (phase-to-ground/neutral and phase-to-phase), frequency, mounting type, termination style, application domain, approval agency, operating temperature, and compliance certifications must all match.

Q2: Is FN3256H-36-33 compatible with previous FN256-36-47 designs?
A2: FN3256H-36-33 matches all provided common parameters and holds the same application, electrical, mechanical, and compliance characteristics as the FN256-36-47.

Q3: Are the packaging and mounting requirements met by the substitute model?
A3: Both parts use tray packaging (where specified), chassis mount configuration, and terminal block terminations.

Q4: Does certification status differ between the main and substitute part?
A4: Both parts are certified by CSA, ENEC, and UR. Both are REACH Unaffected and RoHS compliant in the stated versions.

Q5: Why is substitution necessary for FN256-36-47?
A5: FN256-36-47 is obsolete, requiring an active equivalent matching all stated parameters for continued use in compliant designs.
