Substitute Part Grouping Explanation
Substitution eligibility for the MCR03EZPFX1743 is determined by strict equivalence across the following parameters: resistance value (174 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).
The substitute parts are grouped into two categories:
Direct Equivalents maintain full AEC-Q200 automotive qualification:
- CRCW0603174KFKEA (Vishay Dale)
- ERJ-3EKF1743V (Panasonic Electronic Components)
- RMCF0603FT174K (Stackpole Electronics Inc)
Similar Equivalents maintain all electrical and mechanical specifications but feature moisture-resistant construction instead of automotive AEC-Q200 rating:
- CR0603-FX-1743ELF (Bourns Inc.)
- RC0603FR-07174KL (YAGEO)
All listed parts are currently in active production status with substantial inventory availability.

Engineering Selection Recommendations
For applications requiring strict AEC-Q200 automotive compliance, select from the direct equivalent group: CRCW0603174KFKEA, ERJ-3EKF1743V, or RMCF0603FT174K. All three maintain identical electrical specifications, operating temperature range, and automotive qualification. RMCF0603FT174K offers the highest inventory availability at 46,422 units.
For non-automotive applications or where moisture-resistant construction is acceptable, CR0603-FX-1743ELF and RC0603FR-07174KL are functionally equivalent. RC0603FR-07174KL provides maximum inventory availability at 289,715 units.
All substitute parts maintain RoHS3 compliance and MSL 1 rating consistent with the original MCR03EZPFX1743 specification.
Frequently Asked Questions (FAQ)
Q: Can I use CR0603-FX-1743ELF or RC0603FR-07174KL as direct replacements for MCR03EZPFX1743 in automotive applications?
A: These parts are electrically and mechanically equivalent but lack AEC-Q200 automotive certification. Use only if your application does not require automotive qualification or if design review permits substitution of the moisture-resistant feature for automotive rating.
Q: Are all substitute parts available in the same packaging format?
A: All substitute parts are supplied in Tape & Reel (TR) packaging in 0603 (1608 Metric) case size, matching the original MCR03EZPFX1743 package specification.
Q: What is the significance of the ±100ppm/°C temperature coefficient across all parts?
A: This parameter ensures consistent resistance stability across the -55°C to 155°C operating range. All listed parts maintain identical temperature coefficient performance.
Q: Do all substitute parts meet RoHS3 and MSL 1 requirements?
A: Yes. All direct equivalents and similar equivalents are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental compliance profile.
Q: Which substitute part offers the best inventory availability?
A: RC0603FR-07174KL (YAGEO) provides the highest stock level at 289,715 units. For AEC-Q200 qualified alternatives, RMCF0603FT174K (Stackpole Electronics Inc) offers 46,422 units.
