Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX1801 is determined by strict equivalence across the following parameters:

• Resistance value: 1.8 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts are categorized into two groups: Direct substitutes (functionally identical with AEC-Q200 automotive rating) and Similar substitutes (functionally equivalent but with variations in automotive certification or additional features).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive compliance, direct substitutes with active product status are preferred: ERJ-3EKF1801V (Panasonic), RMCF0603FT1K80 (Stackpole Electronics), and AC0603FR-071K8L (YAGEO). These parts maintain full electrical and mechanical equivalence while offering superior availability.

CRCW06031K80FKEA (Vishay Dale) is an active alternative with AEC-Q200 rating and lower inventory levels. CRCW06031K80FKEB maintains AEC-Q200 compliance but is discontinued.

For non-automotive applications where AEC-Q200 certification is not required, CRG0603F1K8 (TE Connectivity), CR0603-FX-1801ELF (Bourns), and RC0603FR-071K8L (YAGEO) provide functional equivalence with active product status and high availability.

All substitute parts maintain ROHS3 compliance, moisture sensitivity level 1, and identical electrical specifications within the stated tolerance.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different AEC-Q200 certification status? A: Parts without AEC-Q200 rating (CRG0603F1K8, CR0603-FX-1801ELF, RC0603FR-071K8L) are electrically and mechanically equivalent but lack automotive qualification. Selection depends on application requirements.

Q: Are all substitute parts in the same 0603 package? A: Yes. All listed substitutes use the 0603 (1608 Metric) package with identical footprint and mounting characteristics.

Q: What is the difference between CRCW06031K80FKEA and CRCW06031K80FKEB? A: Both are Vishay Dale CRCW series with identical electrical specifications and AEC-Q200 rating. FKEA is active with 5100 pcs inventory; FKEB is discontinued with 40854 pcs available.

Q: Do all substitutes have the same temperature coefficient? A: Yes. All parts listed maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating range.

Q: Which substitute offers the best availability? A: RC0603FR-071K8L (YAGEO) has the highest inventory at 1,000,400 pcs. For AEC-Q200 applications, RMCF0603FT1K80 (Stackpole) offers 192,450 pcs.

Q: Are moisture-resistant variants functionally equivalent? A: AC0603FR-071K8L and CR0603-FX-1801ELF include moisture-resistant features. These provide additional environmental protection while maintaining electrical equivalence with all other parameters.
