- Compliance certifications: CRCW060342K2FKEA and ERJ-3EKF4222V carry Automotive AEC-Q200 certification, matching the original part's automotive qualification.
- Inventory availability: RMCF0603FT42K2 (208,510 pcs), RC0603FR-0742K2L (178,727 pcs), and CR0603-FX-4222ELF (52,724 pcs) offer substantial stock levels.
Frequently Asked Questions (FAQ)
Q: Can I use any of these substitute parts as a direct replacement for MCR03EZPFX4222?
A: Yes. All listed parts meet the electrical and mechanical specifications: 42.2 kOhms ±1%, 0.1W power rating, 0603 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL 1. They are functionally equivalent for circuit applications requiring these parameters.
Q: What is the difference between parts marked "Discontinued," "Obsolete," and "Active"?
A: Product status indicates manufacturing and supply availability. Discontinued parts are no longer produced by the manufacturer but may have residual inventory. Obsolete parts are no longer manufactured and have limited or no availability. Active parts are currently manufactured and have ongoing supply. For new designs or production, active alternatives are recommended.
Q: Do I need to consider Automotive AEC-Q200 certification when selecting a substitute?
A: AEC-Q200 certification is a feature provided by some alternatives (CRCW060342K2FKEA, ERJ-3EKF4222V) but is not a required parameter for functional substitution. If your application requires automotive qualification, select parts with this certification. For non-automotive applications, all alternatives are suitable.
Q: Are there any dimensional differences between these parts?
A: All parts use the 0603 (1608 Metric) package. Minor dimensional variations exist within tolerance (for example, CRCW060342K2FKEA has a maximum seated height of 0.020" versus 0.022" for most others), but these are within standard PCB design tolerances and do not affect substitutability.
Q: What packaging options are available?
A: Substitute parts are available in Tape & Reel (TR) and Cut Tape (CT) packaging. RMCF0603FT42K2, CRCW060342K2FKEA, ERJ-3EKF4222V, CR0603-FX-4222ELF, and RC0603FR-0742K2L are supplied in Tape & Reel. RC1608F4222CS is available in Cut Tape. Select based on your procurement and assembly requirements.
