Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02J512X is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 5.1 kOhms (exact match required)
• Power rating: 0.1W minimum
• Package: 0402 (1005 Metric) form factor
• Operating temperature range: -55°C ~ 155°C minimum
• Automotive qualification: AEC-Q200 required
• RoHS compliance: ROHS3 Compliant

Secondary Compatibility Factors:

• Tolerance specification (±5% or tighter acceptable)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Moisture sensitivity: MSL 1

Substitute parts are grouped into three categories based on their relationship to the main part: direct equivalents (identical specifications), upgrades (improved tolerance), and similar alternatives (different series with equivalent performance).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent: ERJ-U02J512X

The ERJ-U02J512X is a direct functional equivalent to the ERJ-S02J512X. Both parts share identical electrical specifications (5.1 kOhms ±5%, 0.1W), package form factor (0402), and automotive qualifications (AEC-Q200). The primary difference is the product series designation (ERJ-U02 versus ERJ-S02). This part is suitable for direct substitution where supply of the original part is constrained. Higher inventory availability (8879 units) supports procurement flexibility.

Upgrade Option: ERJ-S02F5101X

The ERJ-S02F5101X offers improved tolerance specification (±1% versus ±5%) while maintaining all other critical parameters including resistance value, power rating, package, operating temperature range, and AEC-Q200 automotive qualification. This part remains within the same ERJ-S02 series as the original. Selection of this upgrade is appropriate for applications requiring tighter resistance tolerance. Inventory availability is adequate (7724 units).

Alternative Series: ERJ-2GEJ512X

The ERJ-2GEJ512X represents an alternative from the ERJ-2G series with identical electrical performance (5.1 kOhms ±5%, 0.1W) and package specifications. This part differs in that it does not include anti-sulfur coating, though it maintains full AEC-Q200 automotive qualification and ROHS3 compliance. Exceptional inventory availability (708314 units) makes this option suitable for high-volume applications where anti-sulfur coating is not a design requirement.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02J512X replace ERJ-S02J512X in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, operate across -55°C to 155°C, and share identical electrical specifications (5.1 kOhms ±5%, 0.1W). The series designation difference does not affect functional compatibility.

Q: What is the advantage of ERJ-S02F5101X over the original part?

A: The ERJ-S02F5101X provides ±1% tolerance compared to ±5% tolerance of the ERJ-S02J512X. All other parameters remain identical. Selection depends on circuit requirements for resistance accuracy.

Q: Is ERJ-2GEJ512X suitable as a substitute?

A: ERJ-2GEJ512X is functionally equivalent in electrical performance and package form factor. The key difference is the absence of anti-sulfur coating. Selection should be based on whether anti-sulfur protection is required for the specific application environment.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (ERJ-U02J512X, ERJ-S02F5101X, and ERJ-2GEJ512X) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

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

A: Yes. All parts share the 0402 (1005 Metric) package form factor with identical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and height (0.016" maximum seated height). PCB footprints and assembly processes remain unchanged.

Q: Which substitute offers the best supply availability?

A: ERJ-2GEJ512X has the highest inventory level at 708314 units, followed by ERJ-U02J512X at 8879 units and ERJ-S02F5101X at 7724 units.
