Equivalent & Substitute Parts for ERJ-S02J912X

Part Overview

The ERJ-S02J912X is a 9.1 kOhms ±5% thick film chip resistor in 0402 (1005 Metric) package rated for 0.1W power dissipation. Manufactured by Panasonic Electronic Components, this component features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for automotive and harsh environment applications. The part is currently active in production with 811 units in stock. Alternative part numbers may be required due to inventory constraints, supply chain considerations, or design revision requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S02J912X are qualified based on matching all critical electrical and mechanical parameters: resistance value (9.1 kOhms), 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 substitute parts maintain identical physical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and termination count (2). Compliance certifications including RoHS3, REACH Unaffected, and MSL 1 are preserved across all qualified substitutes. The primary distinction between substitute options lies in series designation and specific feature sets (anti-sulfur coating availability).

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—ERJ-S02J912X, ERJ-U02J912X, and ERJ-2GEJ912X—are functionally equivalent for applications requiring a 9.1 kOhms ±5% 0.1W thick film resistor in 0402 package with automotive AEC-Q200 qualification. Selection between these parts should be based on availability and supply chain requirements rather than electrical performance differences.

ERJ-U02J912X offers the highest inventory availability at 10,949 units and maintains anti-sulfur coating identical to the primary part. ERJ-2GEJ912X provides the largest stock position at 148,798 units but does not include anti-sulfur coating; this variant is suitable for applications where sulfur resistance is not a design requirement. The ERJ-S02J912X remains the primary specification with 811 units available.

All parts maintain identical compliance certifications (RoHS3, REACH Unaffected), moisture sensitivity level (MSL 1), and operating specifications across the full temperature range (-55°C ~ 155°C). Direct substitution is permissible without circuit redesign or re-qualification when inventory or supply constraints necessitate part number changes.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02J912X be used as a direct replacement for ERJ-S02J912X?

A: Yes. Both parts share identical electrical specifications (9.1 kOhms ±5%, 0.1W), mechanical dimensions (0402 package), composition (thick film), temperature characteristics (±200ppm/°C, -55°C ~ 155°C), and automotive qualification (AEC-Q200). Both include anti-sulfur coating. The primary difference is series designation (ERJ-U02 versus ERJ-S02).

Q: What is the difference between ERJ-2GEJ912X and the other two parts?

A: ERJ-2GEJ912X is electrically and mechanically identical to ERJ-S02J912X and ERJ-U02J912X in all critical parameters. The distinction is the absence of anti-sulfur coating on the ERJ-2GEJ912X variant. Selection depends on whether sulfur resistance is required for the application environment.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and are rated for the full automotive temperature range (-55°C ~ 155°C). All are RoHS3 compliant and REACH unaffected.

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

A: Yes. All three parts are identical in package type (0402), footprint dimensions (0.039" L x 0.020" W), and height (0.016" max seated height). They are mechanically and electrically interchangeable without PCB redesign.

Q: Which part should be selected for new designs?

A: For new designs, any of the three parts is acceptable based on availability and supply chain strategy. If sulfur resistance is a design requirement, select ERJ-S02J912X or ERJ-U02J912X. If sulfur resistance is not required, ERJ-2GEJ912X offers superior availability.
