Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02J821X is determined by strict equivalence across the following critical parameters: resistance value (820 Ohms), tolerance (±5%), power rating (0.1W), package type (0402), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). All identified substitutes maintain identical electrical and mechanical specifications across these parameters.

The ERJ-U02J821X qualifies as a direct manufacturer equivalent, differing only in the base series designation (ERJ-U02 versus ERJ-S02) while maintaining all functional and compliance characteristics. The ERJ-2GEJ821X qualifies as a similar substitute, with the distinction that it does not include the anti-sulfur feature present in the primary part, though all other electrical and mechanical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and full compliance with ROHS3 and AEC-Q200 automotive standards. The ERJ-U02J821X provides direct equivalence to the ERJ-S02J821X with significantly higher inventory availability (12,190 pieces versus 885 pieces), making it the preferred substitute for supply chain optimization. The ERJ-2GEJ821X offers the largest inventory position (156,129 pieces) and maintains all core electrical and mechanical specifications; however, the absence of anti-sulfur coating should be evaluated against application requirements in corrosive or high-sulfur environments. Selection between these parts should be based on inventory requirements, supply chain strategy, and specific environmental exposure conditions of the end application.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02J821X be used as a direct replacement for ERJ-S02J821X? A: Yes. The ERJ-U02J821X is electrically and mechanically equivalent to the ERJ-S02J821X. Both parts share identical resistance, tolerance, power rating, package type, temperature coefficient, operating temperature range, and AEC-Q200 automotive qualification. The difference is limited to the base series designation.

Q: What is the difference between ERJ-S02J821X and ERJ-2GEJ821X? A: Both parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, package, and operating specifications. The primary difference is that ERJ-S02J821X includes anti-sulfur coating, while ERJ-2GEJ821X does not. Selection depends on whether anti-sulfur protection is required for the application environment.

Q: Are all substitute parts in the same 0402 package? A: Yes. All three parts use the 0402 (1005 Metric) package with identical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and maximum seated height (0.016", 0.40mm), ensuring direct PCB compatibility.

Q: Do all parts meet automotive standards? A: Yes. All three parts carry AEC-Q200 automotive qualification and are ROHS3 compliant, meeting automotive industry requirements for reliability and environmental compliance.

Q: Which part should be selected for maximum inventory availability? A: The ERJ-2GEJ821X offers the highest inventory level at 156,129 pieces. If anti-sulfur protection is not required, this part provides optimal supply chain availability.
