Engineering Selection Recommendations

1008-221K Selection Criteria: The 1008-221K is suitable for applications where RoHS non-compliant components are acceptable. This part maintains active production status and is available in moderate inventory quantities (766 pieces).

1008R-221K Selection Criteria: The 1008R-221K is the preferred substitute when ROHS3 compliance is required. This variant is manufactured by the same supplier (API Delevan Inc.) and maintains identical electrical and mechanical specifications. The 1008R-221K offers significantly higher inventory availability (5000 pieces), supporting extended production runs and supply chain continuity.

Compliance Considerations: The primary distinction between these parts is RoHS compliance status. The 1008R-221K meets ROHS3 requirements, while the 1008-221K does not. Both parts maintain identical REACH and ECCN classifications. Selection between these parts should be based on end-application regulatory requirements and compliance mandates.

Functional Equivalence: Both parts are electrically and mechanically interchangeable within the specified parameter tolerances. No circuit redesign or board layout modification is required when substituting between these components.

Frequently Asked Questions (FAQ)

Q: Are the 1008-221K and 1008R-221K electrically interchangeable?
