Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S03F2671V is determined by strict equivalence across the following critical parameters:

Resistance Value: 2.67 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power Rating: 0.1W / 1/10W (exact match required)
Package: 0603 (1608 Metric) (exact match required)
Composition: Thick Film (exact match required)
Temperature Coefficient: ±100ppm/°C (exact match required)
Operating Temperature Range: -55°C ~ 155°C (exact match required)
Terminations: 2 (exact match required)
RoHS Compliance: ROHS3 Compliant (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All substitute parts listed below meet these criteria. Variations in features such as automotive AEC-Q200 qualification or moisture resistance coating do not disqualify substitution, as these represent enhanced capabilities rather than reduced functionality.

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the ERJ-S03F2671V and meet identical electrical and mechanical specifications. Selection among these alternatives should be based on the following factors:

Automotive Qualification: The ERJ-S03F2671V, ERJ-3EKF2671V, AC0603FR-072K67L, CRCW06032K67FKEA, CRCW06032K67FKTA, and RMCF0603FT2K67 carry AEC-Q200 automotive qualification. The CR0603-FX-2671ELF and RC0603FR-072K67L do not list AEC-Q200 qualification. For applications requiring automotive-grade components, select from the AEC-Q200 qualified alternatives.

Packaging Format: CRCW06032K67FKEA is supplied in Cut Tape (CT) & Digi-Reel format. All other substitutes are supplied in Tape & Reel (TR) format. Packaging selection depends on assembly process requirements.

Inventory Availability: RC0603FR-072K67L offers the highest inventory level at 319,604 pieces. ERJ-3EKF2671V provides 310,707 pieces. These options support high-volume procurement requirements.

Manufacturer Diversity: Panasonic (ERJ-S03F2671V, ERJ-3EKF2671V), YAGEO (AC0603FR-072K67L, RC0603FR-072K67L), Bourns (CR0603-FX-2671ELF), Vishay Dale (CRCW06032K67FKEA, CRCW06032K67FKTA), and Stackpole Electronics (RMCF0603FT2K67) provide supply chain flexibility across multiple sources.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF2671V be used as a direct replacement for ERJ-S03F2671V?

A: Yes. Both parts are manufactured by Panasonic, share identical electrical specifications (2.67 kΩ ±1%, 0.1W), operate across the same temperature range (-55°C ~ 155°C), use the same 0603 package, and carry ROHS3 compliance. The primary difference is the series designation (ERJ-3EK versus ERJ-S03). Both carry AEC-Q200 automotive qualification.

Q: What is the difference between parts with and without AEC-Q200 qualification?

A: AEC-Q200 qualification indicates the part meets automotive industry reliability standards established by the Automotive Electronics Council. Parts with AEC-Q200 qualification (ERJ-S03F2671V, ERJ-3EKF2671V, AC0603FR-072K67L, CRCW06032K67FKEA, CRCW06032K67FKTA, RMCF0603FT2K67) are suitable for automotive applications. Parts without this designation (CR0603-FX-2671ELF, RC0603FR-072K67L) are suitable for general industrial and consumer applications. Selection depends on application requirements.

Q: Are there physical dimension differences between substitute parts?

A: Most substitutes maintain the standard 0603 package dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) with maximum seated height of 0.022" (0.55mm). Vishay Dale parts (CRCW06032K67FKEA, CRCW06032K67FKTA) have slightly different dimensions: 0.061" L x 0.033" W (1.55mm x 0.85mm) with maximum seated height of 0.020" (0.50mm). These minor variations remain within 0603 package tolerance and do not affect PCB layout compatibility.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. All listed parts carry MSL 1 rating, meaning they do not require special moisture-controlled storage or handling procedures.

Q: Can I mix different manufacturers in the same assembly?

A: Yes. All substitute parts meet identical electrical and mechanical specifications. Mixing manufacturers in the same assembly is permissible from a functional standpoint. However, design documentation and procurement specifications should clearly identify approved part numbers to maintain traceability and consistency.

Q: Which substitute offers the best availability?

A: RC0603FR-072K67L (YAGEO) provides the highest inventory at 319,604 pieces, followed by ERJ-3EKF2671V (Panasonic) at 310,707 pieces. Both support high-volume production requirements.
