Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX18R7 is determined by strict equivalence across the following parameters: resistance value (18.7 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional interchangeability in automotive applications.

The CRCW060318R7FKEA (Vishay Dale), ERJ-3EKF18R7V (Panasonic), and RMCF0603FT18R7 (Stackpole) are direct equivalents with active product status and AEC-Q200 automotive certification. The RC0603FR-0718R7L (YAGEO) is classified as a similar substitute with moisture-resistant features but without explicit AEC-Q200 rating; it maintains all core electrical parameters and package specifications.

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, the CRCW060318R7FKEA, ERJ-3EKF18R7V, and RMCF0603FT18R7 are direct functional equivalents with active product status and full automotive certification. These three parts are interchangeable with the discontinued MCR03EZPFX18R7 across all specified electrical and mechanical parameters.

The RC0603FR-0718R7L maintains electrical equivalence and RoHS3 compliance but lacks explicit AEC-Q200 automotive certification. Selection of this part should be based on application requirements regarding automotive qualification standards.

All substitute parts are available in Tape & Reel packaging and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CRCW060318R7FKEA, ERJ-3EKF18R7V, and RMCF0603FT18R7 be used interchangeably with MCR03EZPFX18R7?

A: Yes. These three parts are direct equivalents. They share identical resistance (18.7 Ohms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive certification. Physical dimensions vary slightly but remain within 0603 package specifications.

Q: Is RC0603FR-0718R7L suitable for automotive applications?

A: RC0603FR-0718L maintains all core electrical parameters and operates within the required temperature range. However, it does not carry explicit AEC-Q200 automotive certification. Use this part only if your application does not mandate automotive qualification standards.

Q: What are the dimensional differences between substitute parts?

A: All parts conform to 0603 (1608 Metric) package specifications. Minor variations exist: MCR03EZPFX18R7 and ERJ-3EKF18R7V measure 0.063" L × 0.031" W (1.60mm × 0.80mm); CRCW060318R7FKEA measures 0.061" L × 0.033" W (1.55mm × 0.85mm); RMCF0603FT18R7 measures 0.061" L × 0.031" W (1.55mm × 0.80mm). All height specifications are 0.022" (0.55mm) maximum except CRCW060318R7FKEA at 0.020" (0.50mm). These variations are within standard 0603 package tolerances and do not affect PCB layout compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the original MCR03EZPFX18R7.

Q: What is the inventory status of substitute parts?

A: CRCW060318R7FKEA has 6,010 units in stock; ERJ-3EKF18R7V has 76,904 units; RMCF0603FT18R7 has 13,639 units; RC0603FR-0718R7L has 10,120 units. All are available as new original stock in Tape & Reel packaging.
