Key Parameters

Substitute Part Grouping Explanation

The RN122-2-02-5M0 qualifies as a direct substitute based on electrical parameter equivalence. Both parts maintain identical specifications across all critical filtering parameters: 5 mH inductance at 10 kHz, 2A current rating, 140 mOhm typical DC resistance, 300V AC voltage rating, 2-line configuration, and -40°C to 100°C operating temperature range. Both components feature through-hole mounting with 4-pin horizontal package configuration and carry equivalent international approvals (ENEC, UR, VDE). The primary distinction is product status: RN122-2-02-1 is Obsolete while RN122-2-02-5M0 is Active, and packaging differs (standard versus tube). These differences do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RN122-2-02-5M0 is the appropriate selection for new designs and ongoing procurement. This part maintains full electrical and mechanical compatibility with RN122-2-02-1 while offering Active product status and current availability. Both components satisfy identical regulatory requirements (ENEC, UR, VDE approvals) and environmental compliance standards (RoHS3, REACH Unaffected). The transition from RoHS Compliant to ROHS3 Compliant represents enhanced regulatory alignment. Packaging format (tube versus standard) does not affect component performance or PCB integration. Inventory availability of 1203 pieces for RN122-2-02-5M0 supports production continuity.

Frequently Asked Questions (FAQ)
