Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S02J122X are qualified based on electrical and mechanical parameter equivalence. The following criteria determine substitutability:

Critical Parameters for Substitution:

• Resistance value: 1.2 kOhms
• Tolerance: ±5%
• Power rating: 0.1W (1/10W)
• Package: 0402 (1005 Metric)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

Direct Equivalent: ERJ-U02J122X meets all critical electrical and mechanical parameters. This part differs only in series designation (ERJ-U02 vs. ERJ-S02) and lacks the anti-sulfur feature present in the main part, but maintains full functional equivalence for standard applications.

Similar Equivalent: ERJ-2GEJ122X meets all critical electrical and mechanical parameters. This part differs in series designation (ERJ-2G vs. ERJ-S02) and does not include the anti-sulfur feature, but maintains full functional equivalence for standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ERJ-S02J122X, ERJ-U02J122X, and ERJ-2GEJ122X—are active production components with ROHS3 compliance and AEC-Q200 automotive qualification. Selection between these parts should be based on application-specific requirements:

ERJ-S02J122X (Main Part): Select when anti-sulfur coating is required for corrosive or high-humidity environments. Current inventory: 951 pieces.

ERJ-U02J122X (Direct Equivalent): Select as a direct substitute when anti-sulfur coating is required and supply of ERJ-S02J122X is constrained. This part maintains the anti-sulfur feature. Current inventory: 10,647 pieces.

ERJ-2GEJ122X (Similar Equivalent): Select when anti-sulfur coating is not a design requirement and maximum inventory availability is prioritized. This part does not include anti-sulfur coating. Current inventory: 173,486 pieces.

All three parts meet identical electrical specifications, thermal performance, and automotive compliance requirements. PCB layout and assembly processes remain unchanged across substitutions.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02J122X replace ERJ-S02J122X in all applications?

A: ERJ-U02J122X is electrically and mechanically equivalent to ERJ-S02J122X. Both parts include anti-sulfur coating and meet identical electrical specifications. Substitution is valid for all standard applications.

Q: What is the difference between ERJ-2GEJ122X and ERJ-S02J122X?

A: Both parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, package, and temperature specifications. The primary difference is that ERJ-2GEJ122X does not include anti-sulfur coating. Select ERJ-2GEJ122X only when anti-sulfur protection is not required.

Q: Are all three parts AEC-Q200 qualified?

A: Yes. ERJ-S02J122X, ERJ-U02J122X, and ERJ-2GEJ122X all carry AEC-Q200 automotive qualification and are suitable for automotive and high-reliability applications.

Q: Do these parts require different PCB footprints?

A: No. All three parts use the 0402 (1005 Metric) package with identical dimensions and termination specifications. PCB footprints and assembly processes are interchangeable.

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

A: All three parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and meet environmental regulatory requirements.
