Key Parameters

Substitute Part Grouping Explanation

The RN222-1-02-33M qualifies as a direct substitute based on matching all critical electrical and mechanical parameters:

• Identical inductance specification: 33 mH @ 10 kHz
• Matching current rating: 1A maximum
• Equivalent DC resistance: 1.3Ohm (Typ)
• Same voltage rating: 300V AC
• Identical operating temperature range: -40°C ~ 100°C
• Matching physical dimensions and mounting configuration
• Equivalent regulatory approvals: ENEC, UR, VDE

The primary distinction is product status and packaging format. The RN222-1-02-33 is obsolete with limited inventory (858 pcs), while RN222-1-02-33M is active with greater availability (1445 pcs). The substitute uses tube packaging versus the original's standard packaging.

Parameter Comparison

Engineering Selection Recommendations

The RN222-1-02-33M is the appropriate selection for new designs and production continuity. This part maintains full electrical and mechanical compatibility with the obsolete RN222-1-02-33 while offering active product status and improved supply chain availability. Both components carry equivalent regulatory certifications (ENEC, UR, VDE) and RoHS compliance, with the substitute meeting ROHS3 specifications. The tube packaging of the substitute does not affect functional performance or board-level integration. For applications currently using RN222-1-02-33, direct substitution with RN222-1-02-33M requires no circuit modifications or design changes.

Frequently Asked Questions (FAQ)

Q: Can RN222-1-02-33M be used as a direct replacement for RN222-1-02-33?

A: Yes. Both parts share identical electrical specifications (33 mH @ 10 kHz, 1A rating, 1.3Ohm DCR, 300V AC), matching physical dimensions, and equivalent regulatory approvals. The substitute is functionally interchangeable at the circuit level.

Q: What is the difference between the original and substitute packaging?

A: RN222-1-02-33 uses standard packaging, while RN222-1-02-33M is supplied in tube packaging. This difference affects handling and storage procedures but does not impact electrical performance or board-level installation.

Q: Why is the original part listed as obsolete?

A: RN222-1-02-33 has reached end-of-life status with Schaffner EMC Inc. The active equivalent RN222-1-02-33M provides continued access to this specification with improved long-term availability.

Q: Are there compliance differences between the two parts?

A: Both parts carry ENEC, UR, and VDE approvals. The substitute meets ROHS3 compliance, while the original meets RoHS Compliant specifications. Both satisfy standard regulatory requirements for power line filtering applications.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by inductance value (33 mH @ 10 kHz), current rating (1A), DC resistance (1.3Ohm), voltage rating (300V AC), operating temperature range (-40°C ~ 100°C), and physical dimensions (31.00mm x 18.00mm x 29.60mm height). All parameters match between the original and substitute.
