Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S03F3480V is determined by strict equivalence across the following parameters:

• Resistance value: 348 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in secondary features (such as anti-sulfur coating or automotive certification) are noted in the comparison table but do not preclude substitution when such features are not design-critical.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical specifications of the ERJ-S03F3480V. Selection among equivalents should be based on the following criteria:

For designs requiring automotive AEC-Q200 certification: ERJ-3EKF3480V, CRCW0603348RFKEA, CRCW0603348RFKTA, and RMCF0603FT348R are qualified options. The ERJ-3EKF3480V offers the highest inventory availability (107,922 units) among AEC-Q200 qualified alternatives.

For designs with RoHS3 compliance requirements: ERJ-3EKF3480V, AC0603FR-07348RL, CR0603-FX-3480ELF, CRCW0603348RFKEA, RC0603FR-07348RL, and RMCF0603FT348R are compliant. CRCW0603348RFKTA is not RoHS3 compliant and should not be selected for applications with regulatory RoHS requirements.

For maximum supply availability: RC0603FR-07348RL (527,850 units) and ERJ-3EKF3480V (107,922 units) provide the largest inventory buffers for high-volume production or extended procurement windows.

For designs without automotive or specific compliance constraints: CR0603-FX-3480ELF and RC0603FR-07348RL offer cost-effective alternatives with substantial inventory.

Frequently Asked Questions (FAQ)

Q: Can ERJ-S03F3480V be directly replaced with ERJ-3EKF3480V?

A: Yes. Both parts are manufactured by Panasonic Electronic Components with identical electrical specifications (348 Ω ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C operating range) and both carry AEC-Q200 automotive qualification and ROHS3 compliance. The primary difference is the series designation (ERJ-S03 versus ERJ-3EK), which reflects internal product line organization but does not affect functional equivalence.

Q: Which substitute parts are suitable for automotive applications?

A: ERJ-3EKF3480V, CRCW0603348RFKEA, CRCW0603348RFKTA, and RMCF0603FT348R all carry AEC-Q200 automotive qualification. CRCW0603348RFKTA is not RoHS3 compliant and may not meet current automotive procurement standards; verify compliance requirements before selection.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist. The ERJ-S03F3480V, ERJ-3EKF3480V, AC0603FR-07348RL, CR0603-FX-3480ELF, RC0603FR-07348RL, and RMCF0603FT348R all measure 0.063" L × 0.031" W (1.60mm × 0.80mm) with 0.022" (0.55mm) maximum seated height. CRCW0603348RFKEA measures 0.061" L × 0.033" W (1.55mm × 0.85mm) with 0.020" (0.50mm) maximum seated height. CRCW0603348RFKTA measures 0.063" L × 0.033" W (1.60mm × 0.85mm) with 0.020" (0.50mm) maximum seated height. These variations are within standard 0603 package tolerances and do not affect PCB footprint compatibility.

Q: What is the difference between anti-sulfur and moisture-resistant coatings?

A: The ERJ-S03F3480V features anti-sulfur coating, while AC0603FR-07348RL, CR0603-FX-3480ELF, and RC0603FR-07348RL feature moisture-resistant coatings. Both coating types are protective measures for thick film resistors. Anti-sulfur coating specifically addresses sulfur contamination in industrial environments. Moisture-resistant coating addresses humidity exposure. Selection depends on the specific environmental conditions of the application.

Q: Can I use RC0603FR-07348RL as a substitute if my design does not require AEC-Q200 certification?

A: Yes. RC0603FR-07348RL meets all core electrical and mechanical specifications and carries ROHS3 compliance. It is not AEC-Q200 qualified, but this is not a limitation for non-automotive applications. RC0603FR-07348RL offers the highest inventory availability (527,850 units) among all listed substitutes.

Q: Is CRCW0603348RFKTA a viable substitute?

A: CRCW0603348RFKTA is electrically and mechanically equivalent but is not RoHS3 compliant and is marked as REACH Affected. It should only be selected for applications where RoHS3 compliance is not a requirement. Verify regulatory and procurement requirements before use.
