Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from CRCW06031K96FKEA (Vishay Dale), ERJ-3EKF1961V (Panasonic), or RMCF0603FT1K96 (Stackpole Electronics). All three maintain active product status with established supply chains.

ERJ-3EKF1961V offers the highest inventory availability at 91,660 pieces. RMCF0603FT1K96 provides a secondary option with 47,763 pieces in stock. CRCW06031K96FKEA is available with 15,032 pieces and maintains Vishay Dale's established quality infrastructure.

For non-automotive applications where AEC-Q200 certification is not required, RC0603FR-071K96L (YAGEO) is available with the largest inventory of 621,555 pieces and active product status. This part maintains all core electrical specifications and RoHS3 compliance.

MCR03ERTF1961 (Rohm Semiconductor) is a direct manufacturer equivalent but shares discontinued status with the original part, limiting its viability for long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX1961 be replaced with any of these substitute parts?

A: Yes. All listed parts meet the core electrical specifications: 1.96 kOhms ±1%, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Selection depends on AEC-Q200 certification requirements and supply availability.

Q: What is the difference between direct substitutes and similar substitutes?

A: Direct substitutes (MCR03ERTF1961, CRCW06031K96FKEA, ERJ-3EKF1961V, RMCF0603FT1K96) maintain AEC-Q200 automotive qualification. RC0603FR-071K96L is classified as a similar substitute because it lacks AEC-Q200 certification but retains all electrical and mechanical specifications.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within tolerance. MCR03EZPFX1961, ERJ-3EKF1961V, and RC0603FR-071K96L measure 0.063" L x 0.031" W (1.60mm x 0.80mm). CRCW06031K96FKEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm). RMCF0603FT1K96 measures 0.061" L x 0.031" W (1.55mm x 0.80mm). All fit standard 0603 footprints.

Q: Which substitute offers the best supply continuity?

A: ERJ-3EKF1961V (Panasonic) provides the highest inventory with 91,660 pieces and active product status. RC0603FR-071K96L (YAGEO) offers 621,555 pieces but lacks AEC-Q200 certification.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating.
