Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified strictly according to matching or compatible parameters: inductance value, current rating, DC resistance, voltage rating, operating temperature range, approval agency certifications, mounting type, package dimensions, line count, and RoHS compliance. Only components meeting these explicit criteria for electrical, mechanical, and certification parameters have been included as direct or similar substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts for RN143-6-02 should be based on product status (obsolete vs. active), RoHS compliance status, and matching approval agencies. Only parts with the same or greater compliance (ENEC, UR, VDE) and current active status are included. For environmental compliance, ensure the chosen model fulfills the stated RoHS requirements. Matching package dimensions, mounting type, and mechanical configuration is also necessary for direct board placement.

Frequently Asked Questions (FAQ)

Q: What is the primary criteria for substituting RN143-6-02?
A: Substitution is based strictly on matching inductance, current rating, package type, DC resistance, operating temperature range, approval agency certifications, mechanical dimensions, and RoHS status.

Q: Are the substitute parts footprint-compatible with RN143-6-02?
A: All listed substitutes share the same mounting type (through hole, horizontal, 4 PC pin) and near-identical dimensions, supporting direct compatibility.

Q: Is there any difference in approval agency certification among substitutes?
A: The substitutes meet equivalent or broader agency certifications (ENEC, UR, VDE).

Q: Can substitutes be used in the same environmental conditions?
A: Substitute selections maintain comparable or overlapping operating temperature ranges and RoHS/REACH statuses.

Q: How does package dimension impact substitution?
A: Package dimension must match for mechanical drop-in replacement in existing PCB layouts; all substitutes meet this criterion.

Q: Does the frequency at which inductance is specified affect compatibility?
A: Substitute inductance values are specified at 10 kHz rather than 1 kHz, but the nominal inductance value remains identical.

Q: What considerations are given for part status?
A: Only active substitutes are selected to ensure ongoing availability and support for production requirements.
