Substitute Part Grouping Explanation

Substitution for the ERJ-S02J302X is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for direct substitution:

• Resistance value: 3 kOhms
• Tolerance: ±5%
• Power rating: 0.1W (1/10W)
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these criteria. Differences in series designation (ERJ-S02, ERJ-U02, ERJ-2G) reflect manufacturing series variations within Panasonic's product portfolio but do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ERJ-S02J302X, ERJ-U02J302X, and ERJ-2GEJ302X—are functionally equivalent and interchangeable for applications requiring a 3 kOhms ±5% 0.1W 0402 thick film resistor with automotive AEC-Q200 qualification.

Selection among these parts should be based on:

• Inventory availability: ERJ-2GEJ302X has the highest stock level (184,454 units), followed by ERJ-U02J302X (5,596 units) and ERJ-S02J302X (692 units).
• Supply chain lead times and procurement preferences.
• Design documentation and qualification history specific to your application.

All parts maintain identical electrical performance, mechanical compatibility, and compliance certifications (ROHS3, AEC-Q200, REACH Unaffected).

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02J302X be used as a direct replacement for ERJ-S02J302X?

A: Yes. Both parts are electrically and mechanically identical 3 kOhms ±5% 0.1W 0402 thick film resistors with AEC-Q200 qualification. The difference in series designation (ERJ-S02 vs. ERJ-U02) reflects manufacturing series variation only and does not affect functional performance or compatibility.

Q: What is the difference between ERJ-2GEJ302X and ERJ-S02J302X?

A: The parts are electrically and mechanically equivalent. ERJ-2GEJ302X lacks the anti-sulfur feature listed for ERJ-S02J302X, but both meet identical electrical specifications, temperature performance, and AEC-Q200 automotive qualification. Selection depends on application-specific environmental requirements and inventory availability.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and operate across the -55°C ~ 155°C temperature range required for automotive use. All are ROHS3 compliant and have MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All three parts share identical 0402 (1005 Metric) package dimensions and footprint specifications. They are compatible with standard SMD assembly equipment and processes without modification.

Q: What certifications apply to all substitute parts?

A: All parts are AEC-Q200 qualified, ROHS3 compliant, and REACH Unaffected. All carry EAR99 export classification and identical HTSUS code (8533.21.0030).
