Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S02J394X are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 390 kOhms
• Tolerance: ±5%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 0402 (1005 Metric)
• Number of terminations: 2
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Height - Seated (Max): 0.016" (0.40mm)

Compliance & Certification (Must Match):

• Automotive AEC-Q200 rating
• RoHS3 compliance
• Moisture Sensitivity Level 1

The ERJ-S02J394X has two qualified substitutes: ERJ-U02J394X (direct equivalent with anti-sulfur feature) and ERJ-2GEJ394X (similar specification without anti-sulfur coating). Both maintain identical electrical performance and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ERJ-S02J394X, ERJ-U02J394X, and ERJ-2GEJ394X—meet identical electrical and mechanical specifications for 390 kOhms ±5% 0.1W 0402 resistor applications. All are active production parts with full AEC-Q200 automotive qualification and ROHS3 compliance.

ERJ-U02J394X is the direct equivalent to ERJ-S02J394X, maintaining the anti-sulfur feature and identical series designation within the ERJ-U02 family. This part is preferred when anti-sulfur coating is a design requirement.

ERJ-2GEJ394X is a similar specification part from the ERJ-2G series without the anti-sulfur feature. This part is suitable for applications where anti-sulfur coating is not required and offers significantly higher inventory availability (114,936 units).

Selection between these parts should be based on design specifications regarding anti-sulfur coating requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02J394X replace ERJ-S02J394X in all applications?

A: Yes. ERJ-U02J394X is a direct equivalent with identical electrical parameters (390 kOhms ±5%, 0.1W), mechanical package (0402), temperature range (-55°C ~ 155°C), and automotive AEC-Q200 qualification. Both include anti-sulfur coating.

Q: What is the difference between ERJ-S02J394X and ERJ-2GEJ394X?

A: Both parts have identical electrical and mechanical specifications. The primary difference is that ERJ-2GEJ394X does not include anti-sulfur coating. If anti-sulfur protection is required by design specifications, ERJ-S02J394X or ERJ-U02J394X must be used.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and are rated for -55°C ~ 155°C operating temperature range, meeting automotive reliability standards.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All three parts share identical 0402 (1005 Metric) package dimensions and footprint requirements, allowing direct substitution without PCB redesign.

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

A: All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected.
