Substitute Part Grouping Explanation

Substitution between the ERJ-S02J1R3X and ERJ-U02J1R3X is based on electrical and mechanical parameter equivalence. Both parts share identical specifications for resistance value (1.3 Ohms), tolerance (±5%), power rating (0.1W), package format (0402 / 1005 Metric), composition (thick film), automotive qualification (AEC-Q200), temperature coefficient (-100 / +600 ppm/°C), operating temperature range (-55°C ~ 155°C), physical dimensions, and compliance certifications (ROHS3, REACH Unaffected).

The primary distinction between these parts is the packaging format: ERJ-S02J1R3X is supplied in standard packaging, while ERJ-U02J1R3X is supplied in Tape & Reel (TR) format. Both parts are manufactured by Panasonic Electronic Components and maintain full electrical and mechanical compatibility. The substitution is valid for applications where packaging format does not impose constraints on assembly or procurement workflows.

Parameter Comparison

Engineering Selection Recommendations

Both ERJ-S02J1R3X and ERJ-U02J1R3X are active production parts manufactured by Panasonic Electronic Components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on packaging and supply chain requirements:

ERJ-S02J1R3X is appropriate for applications where standard packaging is acceptable and inventory availability is the primary consideration (932 pieces in stock).

ERJ-U02J1R3X is appropriate for high-volume production environments utilizing automated tape-and-reel assembly processes, with significantly higher inventory availability (10,476 pieces in stock).

Both parts satisfy identical electrical performance requirements, thermal specifications, and regulatory compliance standards. The choice between them does not affect circuit performance or reliability characteristics.
