Engineering Selection Recommendations

Direct Equivalent (Packaging Variant): RG2012N-7322-B-T5 is the direct equivalent to RG2012N-7322-B-T1, differing only in packaging format (Tape & Reel versus Tube). This part maintains identical electrical specifications and is currently in active production status. Selection of this part is appropriate for applications requiring the same performance characteristics with standard tape and reel packaging.

Upgraded Tolerance Alternatives: RG2012N-7322-W-T1 and RG2012N-7322-W-T5 offer improved tolerance of ±0.05% compared to the original ±0.1%. Both parts are manufactured by Susumu and maintain all other electrical and thermal specifications. These parts are suitable for applications requiring tighter resistance tolerance while maintaining compatibility with the original design envelope.

Cross-Manufacturer Alternative (Higher Power Rating): TNPW080573K2BYEA (Vishay Dale) provides equivalent resistance and tolerance with increased power rating of 0.26W and extended operating temperature range to 175°C. This part is suitable for applications where thermal margin or higher power dissipation capability is beneficial. The temperature coefficient remains ±10ppm/°C, matching the original specification.

Cross-Manufacturer Alternative (Standard Specifications): ERA-6AEB7322V (Panasonic Electronic Components) provides direct functional equivalence with identical resistance, tolerance, and power rating. The temperature coefficient is ±25ppm/°C, which is within acceptable variation for most applications. This part offers the highest inventory availability and is suitable for general replacement applications.

All substitute parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with automotive and industrial applications.
