Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (301 Ohms), tolerance (±1%), power rating (0.1W), package format (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and termination count (2). All identified substitute parts meet these core electrical and mechanical specifications. Substitutes are grouped by manufacturer and product status to facilitate selection based on availability and compliance requirements. Automotive AEC-Q200 rating and RoHS3 compliance are present across all active substitutes, ensuring suitability for regulated applications.

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification with active product status and full RoHS3 compliance, select from: ERJ-3EKF3010V (Panasonic), AC0603FR-07301RL (YAGEO), AF0603FR-07301RL (YAGEO), CRCW0603301RFKEA (Vishay Dale), or RMCF0603FT301R (Stackpole Electronics). These parts maintain all specified electrical parameters and regulatory certifications.

For non-automotive applications or where AEC-Q200 is not required, CR0603-FX-3010ELF (Bourns) and RC0603FR-07301RL (YAGEO) are electrically equivalent alternatives with RoHS3 compliance and active status.

CRCW0603301RFKEB is discontinued at DiGi Electronics and should not be selected for new designs. CRCW0603301RFKTA is active but does not carry RoHS3 compliance and is REACH-affected; use only where legacy compliance requirements apply.

Frequently Asked Questions (FAQ)

Q: Can ERJ-S03F3010V be directly replaced with ERJ-3EKF3010V? A: Yes. Both parts are manufactured by Panasonic, share identical electrical specifications (301Ω ±1%, 0.1W), operate across the same temperature range (-55°C to 155°C), carry AEC-Q200 rating, and are RoHS3 compliant. The primary difference is series designation (ERJ-S03 versus ERJ-3EK). Both are packaged in 0603 format with tape and reel delivery.

Q: What is the difference between YAGEO AC0603FR-07301RL and AF0603FR-07301RL? A: Both are YAGEO 301Ω ±1% 0.1W 0603 resistors with AEC-Q200 rating and RoHS3 compliance. AF0603FR-07301RL includes anti-sulfur construction, matching the ERJ-S03F3010V feature set. AC0603FR-07301RL provides moisture-resistant construction. Selection depends on environmental exposure requirements.

Q: Are there packaging differences between substitutes? A: Yes. Most substitutes are supplied in tape and reel format. CRCW0603301RFKEA, CRCW0603301RFKTA, and RC0603FR-07301RL are available in cut tape with Digi-Reel format. Verify packaging compatibility with assembly equipment before selection.

Q: Which substitute has the highest inventory availability? A: CRCW0603301RFKEA (Vishay Dale) shows 145,282 pieces in stock, followed by RMCF0603FT301R (Stackpole) with 133,837 pieces. Both are active products with full compliance certifications.

Q: Can CRCW0603301RFKTA be used in automotive applications? A: CRCW0603301RFKTA carries AEC-Q200 rating but is not RoHS3 compliant and is REACH-affected. Use only in applications where legacy compliance or specific customer requirements mandate this part number.

Q: What distinguishes Bourns CR0603-FX-3010ELF from automotive-rated alternatives? A: CR0603-FX-3010ELF does not carry AEC-Q200 automotive qualification. It is suitable for general industrial and consumer applications requiring moisture-resistant thick film construction with RoHS3 compliance and -55°C to 155°C operating range.
