Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02J304X is determined by strict equivalence across the following critical parameters:

Resistance value: 300 kOhms
Tolerance: ±5%
Power rating: 0.1W
Package: 0402 (1005 Metric)
Composition: Thick Film
Temperature coefficient: ±200ppm/°C
Operating temperature range: -55°C ~ 155°C
AEC-Q200 automotive qualification

Engineering Selection Recommendations

All three part numbers—ERJ-S02J304X, ERJ-U02J304X, and ERJ-2GEJ304X—are functionally equivalent for applications requiring a 300 kOhms ±5% 0.1W 0402 thick film resistor with automotive AEC-Q200 qualification. Selection between these parts should be based on:

Inventory availability and lead time requirements
Supply chain preferences and established vendor relationships
Manufacturing series consistency with existing bill of materials documentation
Anti-sulfur feature requirement (ERJ-S02J304X and ERJ-U02J304X include anti-sulfur coating; ERJ-2GEJ304X does not)

All parts maintain active production status, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1), ensuring long-term availability and environmental regulation adherence.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02J304X be used as a direct replacement for ERJ-S02J304X?

A: Yes. Both parts share identical electrical specifications (300 kOhms ±5%, 0.1W), mechanical dimensions (0402 package), temperature characteristics (±200ppm/°C, -55°C ~ 155°C), and automotive qualification (AEC-Q200). The primary difference is the manufacturing series designation. Both include anti-sulfur coating.

Q: What is the difference between ERJ-2GEJ304X and the other two part numbers?

A: ERJ-2GEJ304X is electrically and mechanically identical to ERJ-S02J304X and ERJ-U02J304X. The key difference is that ERJ-2GEJ304X does not include anti-sulfur coating, while ERJ-S02J304X and ERJ-U02J304X do. All three parts meet AEC-Q200 automotive standards and are suitable for the same applications.

Q: Are there any package or footprint differences between these parts?

A: No. 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 of 0.016" (0.40mm). PCB footprints and assembly processes are interchangeable.

Q: Do all substitute parts have the same temperature operating range?

A: Yes. All three parts operate across the identical temperature range of -55°C to 155°C with a temperature coefficient of ±200ppm/°C.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
