Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series - Same Manufacturer):

RG2012P-4422-B-T5 and RG2012N-4422-B-T5 are direct Susumu alternatives with improved tolerance (±0.1% versus ±0.25%) and active product status. Both maintain AEC-Q200 automotive qualification, ROHS3 compliance, and identical package dimensions. RG2012N-4422-B-T5 offers superior temperature coefficient (±10ppm/°C) compared to the original specification.

RG2012P-4422-W-T5 and RG2012N-4422-W-T1 provide the tightest tolerance specification (±0.05%) within the Susumu RG series, with active status and full automotive qualification.

Secondary Substitutes (Multi-Manufacturer Options):

ERA-6AEB4422V (Panasonic) offers ±0.1% tolerance with AEC-Q200 certification and active status. This part maintains identical electrical specifications to RG2012P-4422-B-T5 with significantly higher inventory availability (13,335 units).
