Substitute Part Grouping Explanation

Substitute parts for the ERJ-S03F2673V are qualified based on the following criteria:

Electrical Parameters: Resistance value (267 kOhms), tolerance (±1%), power rating (0.1W), and temperature coefficient (±100ppm/°C) must match exactly.

Mechanical Parameters: Package type (0603 / 1608 Metric) and physical dimensions must be compatible with the original footprint.

Environmental & Compliance: Operating temperature range (-55°C ~ 155°C), RoHS3 compliance, and MSL rating (1 - Unlimited) must be maintained.

Certifications: Automotive AEC-Q200 rating is present in the main part and several substitutes, indicating suitability for automotive applications. Parts without this certification remain functionally equivalent for non-automotive use cases.

All identified substitutes meet these core parameters and are suitable for direct replacement in the same circuit application.

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the ERJ-S03F2673V. Selection should be based on application requirements and compliance certifications:

For Automotive Applications: ERJ-3EKF2673V (Panasonic), AC0603FR-07267KL (YAGEO), CRCW0603267KFKEA (Vishay Dale), and RMCF0603FT267K (Stackpole Electronics Inc) all carry AEC-Q200 automotive qualification and are suitable for automotive circuit designs.

For General Industrial Applications: CR0603-FX-2673ELF (Bourns Inc.) and RC0603FR-07267KL (YAGEO) are functionally equivalent and RoHS3 compliant, suitable for non-automotive applications.

Availability Considerations: RC0603FR-07267KL offers the highest inventory level (186,742 units), while ERJ-3EKF2673V provides substantial stock (61,696 units) from the same manufacturer as the primary part.

All parts are ROHS3 compliant with MSL rating 1 (Unlimited moisture sensitivity), ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF2673V be used as a direct replacement for ERJ-S03F2673V?

A: Yes. Both parts are manufactured by Panasonic, share identical electrical specifications (267 kOhms ±1%, 0.1W), operate across the same temperature range (-55°C ~ 155°C), carry AEC-Q200 certification, and use the 0603 package. The primary difference is the series designation (ERJ-3EK vs. ERJ-S03), but electrical and mechanical performance are equivalent.

Q: Are non-AEC-Q200 parts suitable for automotive applications?

A: No. Automotive applications requiring AEC-Q200 qualification must use parts explicitly rated for this standard. CR0603-FX-2673ELF and RC0603FR-07267KL lack AEC-Q200 certification and should not be used in automotive designs requiring this qualification.

Q: Do all substitute parts fit the same PCB footprint?

A: Yes. All listed parts use the 0603 (1608 Metric) package. Physical dimensions are within acceptable tolerances for standard 0603 footprints, with minor variations in height (0.50mm to 0.55mm seated height) that do not affect PCB assembly compatibility.

Q: What is the significance of the anti-sulfur feature in ERJ-S03F2673V?

A: The anti-sulfur coating in the ERJ-S03F2673V provides enhanced corrosion resistance in harsh environments. Substitute parts without explicit anti-sulfur designation (such as AC0603FR-07267KL and RC0603FR-07267KL) feature moisture-resistant thick film construction, which provides equivalent environmental protection for most applications.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts, including the main part and all substitutes, are ROHS3 compliant and suitable for use in regions with RoHS regulations.

Q: What does MSL 1 (Unlimited) mean for component handling?

A: MSL 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is required before PCB assembly.
