Substitute Part Grouping Explanation

Substitution between 1008-220K and 1008R-220K is valid based on the following criteria:

Electrical Equivalence Parameters:

• Identical inductance value: 22 nH
• Identical inductance tolerance: ±10%
• Identical current rating: 1.235 A
• Identical DC resistance specification: 80 mOhm Max
• Identical Q factor: 35 @ 50 MHz
• Identical self-resonant frequency: 1.8 GHz
• Identical core material: Phenolic
• Identical shielding configuration: Unshielded

Mechanical Equivalence Parameters:

• Identical physical dimensions: 0.105" L × 0.095" W (2.66 mm × 2.41 mm)
• Identical seated height: 0.095" (2.41 mm)
• Identical mounting type: Surface Mount
• Identical package category: Nonstandard
• Identical packaging format: Tape & Reel

Operational Equivalence Parameters:

• Identical operating temperature range: -55°C to 125°C
• Identical inductance test frequency: 50 MHz
• Identical moisture sensitivity level: 1 (Unlimited)

The primary distinction between these parts is the RoHS compliance status, where 1008R-220K provides ROHS3 compliance while 1008-220K is RoHS non-compliant. Both parts share identical REACH and ECCN classifications.

Parameter Comparison

Engineering Selection Recommendations

1008-220K Selection Criteria:

• Applications without RoHS compliance requirements
• Legacy designs where RoHS non-compliant components are acceptable
• Cost-sensitive applications where RoHS compliance is not mandated
• Current inventory availability: 1109 pieces

1008R-220K Selection Criteria:

• Applications requiring ROHS3 compliance certification
• New designs subject to RoHS directive requirements
• Supply chain requirements mandating compliant components
• Current inventory availability: 1362 pieces

Both parts maintain identical electrical performance, mechanical compatibility, and operational specifications. Selection between these parts is determined solely by regulatory compliance requirements and supply chain constraints, not by functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can 1008R-220K replace 1008-220K in existing designs?

A: Yes. The 1008R-220K is electrically and mechanically equivalent to 1008-220K.
