Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S03F2261V is determined by strict equivalence across the following parameters:

• Resistance value: 2.26 kOhms
• Tolerance: ±1%
• Power rating: 0.1W
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical requirements. Variations in features such as automotive AEC-Q200 qualification or moisture resistance do not disqualify substitution but indicate enhanced capability for specific application environments.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance, meeting the core electrical and mechanical requirements of the ERJ-S03F2261V. Selection among these alternatives should be based on:

Automotive Applications: Parts carrying AEC-Q200 qualification (ERJ-3EKF2261V, AC0603FR-072K26L, CRCW06032K26FKEA, RMCF0603FT2K26) are suitable for automotive-grade circuit designs. The original ERJ-S03F2261V includes anti-sulfur coating in addition to AEC-Q200 rating.

Moisture-Sensitive Environments: Parts with moisture-resistant features (AC0603FR-072K26L, CR0603-FX-2261ELF, RC0603FR-072K26L) provide enhanced protection in high-humidity or corrosive atmospheres.

Supply Availability: RC0603FR-072K26L and RMCF0603FT2K26 maintain the highest inventory levels (228,759 and 216,337 units respectively), supporting high-volume production requirements.

Standard Industrial Applications: CRG0603F2K26 meets all electrical specifications without specialized features, suitable for general-purpose applications where automotive or environmental certifications are not required.

Frequently Asked Questions (FAQ)

Q: Can I substitute ERJ-S03F2261V with any of the listed parts without circuit redesign?

A: Yes. All listed parts are electrically and mechanically equivalent, sharing identical resistance value (2.26 kOhms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). Direct substitution is valid at the component level.

Q: What is the difference between AEC-Q200 qualified and non-qualified parts?

A: AEC-Q200 qualification indicates the part has passed automotive-grade reliability testing and is approved for use in automotive applications. Parts without this rating (CRG0603F2K26) are suitable for industrial and consumer applications but should not be used in automotive designs requiring AEC-Q200 compliance.

Q: Does the anti-sulfur coating on the ERJ-S03F2261V make it superior to other substitutes?

A: Anti-sulfur coating provides additional protection against sulfur-containing atmospheric contaminants, extending reliability in harsh industrial environments. This feature is specific to the ERJ-S03F2261V and not present in other listed substitutes. For applications not exposed to sulfur contamination, this distinction does not affect functional performance.

Q: Are there dimensional differences between substitute parts?

A: Nominal package dimensions are 0603 (1608 Metric) for all parts. Minor variations exist in maximum seated height: most parts specify 0.022" (0.55mm), while CRCW06032K26FKEA specifies 0.020" (0.50mm). These variations remain within standard 0603 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Which substitute offers the best value for high-volume production?

A: RC0603FR-072K26L and RMCF0603FT2K26 provide the highest inventory availability (228,759 and 216,337 units respectively), supporting large-scale manufacturing without supply constraints. Both maintain AEC-Q200 qualification or moisture resistance features, ensuring performance reliability.

Q: Can I mix different substitute parts in the same production batch?

A: Yes. All parts meet identical electrical specifications and package requirements. Mixing substitutes within a single design is permissible from an electrical standpoint. However, manufacturing and quality control procedures should document which part number is used in each unit for traceability and warranty purposes.
