Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX1150 is determined by strict equivalence across the following parameters: resistance value (115 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 (AEC-Q200, ROHS3, REACH Unaffected).

The substitute parts are grouped into two categories:

Direct Substitutes maintain full automotive AEC-Q200 certification and identical electrical specifications: CRCW0603115RFKEA (Vishay Dale), ERJ-3EKF1150V (Panasonic Electronic Components), and RMCF0603FT115R (Stackpole Electronics Inc).

Similar Substitute meets all electrical and mechanical parameters but features moisture-resistant composition instead of automotive AEC-Q200 rating: RC0603FR-07115RL (YAGEO).

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from the direct substitutes: CRCW0603115RFKEA (Vishay Dale, 43,130 units in stock), ERJ-3EKF1150V (Panasonic Electronic Components, 69,339 units in stock), or RMCF0603FT115R (Stackpole Electronics Inc, 3,046 units in stock). All three maintain full automotive qualification and identical electrical specifications to the original MCR03EZPFX1150.

The RC0603FR-07115RL (YAGEO, 1,427 units in stock) is suitable only for non-automotive applications where AEC-Q200 certification is not required, as it features moisture-resistant composition without automotive rating.

All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 rating, matching the original part's environmental and regulatory status.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-07115RL be used in automotive applications? A: No. RC0603FR-07115RL lacks AEC-Q200 automotive certification. Use only CRCW0603115RFKEA, ERJ-3EKF1150V, or RMCF0603FT115R for automotive designs.

Q: Are all substitute parts pin-compatible with MCR03EZPFX1150? A: Yes. All substitutes use identical 0603 (1608 Metric) package with two terminations and are mechanically compatible for PCB assembly.

Q: What is the difference between direct substitutes and similar substitutes? A: Direct substitutes (CRCW0603115RFKEA, ERJ-3EKF1150V, RMCF0603FT115R) carry AEC-Q200 automotive certification. The similar substitute (RC0603FR-07115RL) does not and is limited to non-automotive use.

Q: Do all substitutes meet the same temperature and tolerance specifications? A: Yes. All substitutes maintain ±1% tolerance, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range.

Q: Which substitute has the highest inventory availability? A: ERJ-3EKF1150V (Panasonic Electronic Components) with 69,339 units in stock.
