Engineering Selection Recommendations

For Standard Applications with Active Product Status: CR0603-FX-4320ELF (Bourns Inc.) and RC0603FR-07432RL (YAGEO) are primary equivalents. Both maintain identical electrical specifications, ROHS3 compliance, and active product status. Selection between these two is based on inventory availability and supply chain preference. CR0603-FX-4320ELF offers higher inventory levels (14,187 pcs) compared to RC0603FR-07432RL (5,950 pcs).

For Automotive and High-Reliability Applications: ERJ-3EKF4320V (Panasonic), RMCF0603FT432R (Stackpole), and CRCW0603432RFKEA (Vishay Dale) incorporate AEC-Q200 automotive qualification. These parts are suitable for applications requiring enhanced reliability testing and automotive-grade performance. ERJ-3EKF4320V provides the highest inventory availability (192,764 pcs) among automotive-qualified variants.

For Legacy Design Continuity: MCR03ERTF4320 (Rohm Semiconductor) meets all electrical and mechanical specifications but carries discontinued status at DiGi Electronics. This part should be selected only when existing inventory is available (892 pcs) and long-term supply is not required.

Regulatory Compliance Consideration: CRCW0603432RFKTA (Vishay Dale) is RoHS non-compliant and REACH-affected. This part should not be selected for new designs or applications requiring ROHS3 compliance. CRCW0603432RFKEA (Vishay Dale) is the compliant variant of the same series.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-4320ELF be used as a direct replacement for RC1608F4320CS?

A: Yes. CR0603-FX-4320ELF meets all mandatory electrical and mechanical parameters: 432 Ohm resistance, ±1% tolerance, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both parts are ROHS3 compliant with active product status.
