Key Parameters

Substitute Part Grouping Explanation

Substitution classification is determined by strict alignment of the following parameters:

Primary Substitution Criteria:

• Resistance value: 294 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Direct Equivalents meet all primary criteria with identical mechanical and electrical specifications.

Similar Substitutes meet all primary criteria but include additional certifications (AEC-Q200 automotive qualification) that do not restrict their use in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: CR0603-FX-2943ELF (Bourns Inc.) and RC0603FR-07294KL (YAGEO) are direct functional equivalents to RC1608F2943CS. Both components share identical electrical parameters, mechanical dimensions, and compliance certifications. Selection between these options is based on inventory availability and supply chain requirements.

Automotive-Qualified Alternatives: AC0603FR-07294KL (YAGEO), CRCW0603294KFKEA (Vishay Dale), and ERJ-3EKF2943V (Panasonic Electronic Components) incorporate AEC-Q200 automotive qualification. These components meet all electrical and mechanical specifications of the original part and are suitable for applications requiring automotive-grade reliability. AEC-Q200 certification does not restrict use in non-automotive applications.

Compliance Status: All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can AC0603FR-07294KL replace RC1608F2943CS in non-automotive applications? A: Yes. AEC-Q200 automotive qualification is a superset of standard reliability requirements. Components with automotive certification are suitable for general-purpose applications.

Q: Are there dimensional differences between substitute parts? A: CRCW0603294KFKEA has slightly different dimensions (0.061" L x 0.033" W, height 0.020" max) compared to the primary specification (0.063" L x 0.031" W, height 0.022" max). Verify PCB footprint compatibility before selection.

Q: What is the significance of MSL Level 1 rating? A: MSL Level 1 indicates unlimited shelf life without moisture baking requirements. All listed parts share this rating, eliminating moisture sensitivity as a substitution constraint.

Q: Which substitute offers the highest inventory availability? A: RC0603FR-07294KL (YAGEO) provides 177,269 pieces in stock, the highest among all listed alternatives.

Q: Do all substitutes meet RoHS3 compliance? A: Yes. All listed parts are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Is temperature coefficient identical across all parts? A: Yes. All parts specify ±100ppm/°C temperature coefficient and -55°C ~ 155°C operating range, ensuring thermal performance equivalence.
