Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX1180 is determined by strict equivalence across the following parameters: resistance value (118 Ohms), 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, REACH Unaffected, EAR99).

Direct substitutes maintain all electrical and mechanical specifications including AEC-Q200 automotive qualification. The similar substitute (RC0603FR-07118RL by YAGEO) meets all electrical parameters and dimensional requirements but features moisture-resistant construction instead of automotive AEC-Q200 rating, making it suitable for applications where automotive qualification is not mandatory.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from CRCW0603118RFKEA (Vishay Dale), ERJ-3EKF1180V (Panasonic Electronic Components), or RMCF0603FT118R (Stackpole Electronics Inc). All three maintain full automotive compliance and are currently in active production with substantial inventory availability.

CRCW0603118RFKEA offers the highest inventory level (18,134 pcs) and is supplied in Tape & Reel packaging. ERJ-3EKF1180V provides the largest available stock (50,993 pcs) and maintains identical dimensional specifications to the original part. RMCF0603FT118R offers a mid-range inventory position (23,946 pcs) with slightly reduced length dimensions (0.061" vs 0.063").

RC0603FR-07118RL by YAGEO is suitable for non-automotive applications where AEC-Q200 qualification is not required. This part features moisture-resistant construction and maintains all electrical parameters with identical dimensional specifications to the original part.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-07118RL be used in automotive applications? A: RC0603FR-07118RL does not carry AEC-Q200 automotive qualification. Use only in applications where automotive certification is not a requirement. For automotive applications, select CRCW0603118RFKEA, ERJ-3EKF1180V, or RMCF0603FT118R.

Q: Are all substitute parts pin-compatible with the original MCR03EZPFX1180? A: Yes. All listed substitutes use the 0603 (1608 Metric) package with two terminations and are mechanically compatible for PCB assembly. Dimensional variations are within acceptable tolerances for standard pick-and-place equipment.

Q: What is the difference between direct substitutes and similar substitutes? A: Direct substitutes (CRCW0603118RFKEA, ERJ-3EKF1180V, RMCF0603FT118R) maintain AEC-Q200 automotive qualification identical to the original part. The similar substitute (RC0603FR-07118RL) meets all electrical and dimensional specifications but uses moisture-resistant construction instead of automotive qualification.

Q: Which substitute offers the best availability? A: ERJ-3EKF1180V by Panasonic Electronic Components currently has the highest inventory level at 50,993 pieces in stock.

Q: Are there any dimensional differences between substitutes? A: Minor dimensional variations exist within acceptable tolerances. RMCF0603FT118R has a length of 0.061" compared to 0.063" for other parts. Height specifications range from 0.020" to 0.022" maximum seated height. These variations do not affect PCB assembly compatibility.
