Substitute Part Grouping Explanation

Substitution of the CR75-2R2MC is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 2.2 µH
• Tolerance: ±20%
• Current rating: 4.5 A minimum
• DC resistance: 19.5 mOhm maximum
• Self resonant frequency: 36.4 MHz

Mechanical Parameters:

• Core material: Ferrite
• Core type: Drum core, wirewound
• Shielding configuration: Unshielded
• Mounting: Surface mount
• Physical footprint: 7.80mm × 7.00mm × 5.50mm maximum

Environmental Parameters:

• Operating temperature range: Must support -30°C to 100°C minimum
• Moisture sensitivity level: 1 (Unlimited)

The CR75NP-2R2MC qualifies as a direct substitute based on identical electrical specifications, core construction, physical dimensions, and environmental ratings. Packaging format differences do not affect functional equivalence.

Engineering Selection Recommendations

Primary Substitute: CR75NP-2R2MC

The CR75NP-2R2MC is the direct functional equivalent of the CR75-2R2MC. Selection of this substitute is based on the following engineering factors:

1. Electrical Equivalence: All critical electrical parameters—inductance, current rating, DC resistance, and frequency response—are identical between the two parts.

2. Mechanical Compatibility: Physical dimensions and mounting configuration are identical, ensuring direct PCB footprint compatibility without design modification.

3. Product Status: The CR75NP-2R2MC is classified as active production, providing assured long-term supply availability compared to the obsolete CR75-2R2MC.

4. Compliance Enhancement: The CR75NP-2R2MC meets ROHS3 compliance requirements, whereas the CR75-2R2MC is non-compliant. For applications subject to RoHS regulations, the substitute is mandatory.

5. Environmental Performance: The CR75NP-2R2MC supports an extended operating temperature range (-40°C to 100°C), providing additional thermal margin beyond the CR75-2R2MC specification (-30°C to 100°C).

6. Packaging Flexibility: While the CR75-2R2MC is supplied in bulk format, the CR75NP-2R2MC is available in Tape & Reel packaging, supporting automated assembly processes.

No design changes, circuit modifications, or performance trade-offs are required when substituting CR75NP-2R2MC for CR75-2R2MC.

Frequently Asked Questions (FAQ)

Q: Can CR75NP-2R2MC be used as a direct replacement for CR75-2R2MC without PCB modification?
