Engineering Selection Recommendations

For applications requiring ROHS3 compliance and active product status with maximum inventory availability, LP2985A-50DBVR is the primary selection, offering 80,100 pieces in stock. This part maintains full electrical and mechanical equivalence to the LP2985IM5X-5.0 while providing superior supply continuity.

For designs with REACH compliance requirements and active status, LP2985AIM5X-5.0/NOPB and LP2985IM5X-5.0/NOPB both provide ROHS3 compliance with 27,990 and 26,400 pieces respectively.

Parts designated as Last Time Buy (LP2985IM5X-5.0, LP2985AIM5-5.0, LP2985IM5-5.0) should be evaluated for long-term production requirements. LP2985AIM5-5.0 carries RoHS non-compliance status and REACH Affected designation, limiting suitability for regulated applications.

Packaging variants (DBVR, DBVT, IM5, IM5X) represent different tape and reel configurations. Selection between these variants depends on procurement and assembly line requirements rather than electrical performance.

Frequently Asked Questions (FAQ)
