Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (4.67 kOhms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3, MSL 1).

Parts are categorized as direct substitutes when all electrical and mechanical parameters match exactly. Parts designated as similar substitutes meet all core electrical specifications and package requirements but differ in specific feature classifications (such as automotive AEC-Q200 rating versus moisture-resistant designation).

Parameter Comparison

Engineering Selection Recommendations

Direct substitutes with automotive AEC-Q200 certification are CRCW06033K57FKEA (Vishay Dale), ERJ-3EKF3571V (Panasonic Electronic Components), and RMCF0603FT3K57 (Stackpole Electronics Inc). These parts maintain full compliance with automotive qualification standards and are currently in active production with substantial inventory availability.

For applications where automotive AEC-Q200 certification is not a mandatory requirement, CR0603-FX-3571ELF (Bourns Inc.) and RC0603FR-073K57L (YAGEO) provide equivalent electrical performance with moisture-resistant thick film construction. All substitute options maintain RoHS3 compliance and MSL 1 rating.

Selection should prioritize parts with active product status and confirmed inventory availability for supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX3571 be replaced with any of these substitute parts? A: Direct substitution is possible with CRCW06033K57FKEA, ERJ-3EKF3571V, and RMCF0603FT3K57, which maintain identical electrical specifications and automotive AEC-Q200 certification. CR0603-FX-3571ELF and RC0603FR-073K57L are functionally equivalent but lack automotive AEC-Q200 rating; use only if automotive qualification is not required.

Q: Are there physical dimension differences between substitute parts? A: All parts conform to 0603 (1608 Metric) package standard. Minor variations exist in seated height and length/width dimensions within standard tolerances. CRCW06033K57FKEA and RMCF0603FT3K57 measure 0.061" L × 0.031" W and 0.061" L × 0.031" W respectively, while others measure 0.063" L × 0.031" W. These variations are within PCB design tolerances for 0603 packages.

Q: What is the difference between AEC-Q200 and moisture-resistant designations? A: AEC-Q200 certification indicates automotive-grade qualification with defined reliability and performance standards. Moisture-resistant designation indicates enhanced protection against moisture ingress. Both feature sets are compatible with RoHS3 and MSL 1 ratings. Selection depends on application requirements.

Q: Are all substitute parts available in Tape & Reel packaging? A: Yes, all listed substitute parts are available in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Do substitute parts maintain the same temperature coefficient? A: All substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, ensuring thermal performance equivalence.
