Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (2.2 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, REACH Unaffected, EAR99).

Parts are classified into two categories:

Direct Substitutes maintain all electrical and mechanical parameters with identical or compatible packaging configurations (Cut Tape, Tape & Reel variants):

• CRCW06032K20FKEA (Vishay Dale)
• CRCW06032K20FKEB (Vishay Dale)
• ERJ-3EKF2201V (Panasonic Electronic Components)
• RMCF0603FT2K20 (Stackpole Electronics Inc)

Similar Substitutes meet all core electrical specifications and package requirements but may include additional features or minor dimensional variations:

• CR0603-FX-2201ELF (Bourns Inc.)
• CRG0603F2K2 (TE Connectivity Passive Product)
• ERJ-S03F2201V (Panasonic Electronic Components)
• RC0603FR-072K2L (YAGEO)
• RC1608F222CS (Samsung Electro-Mechanics)

Parameter Comparison

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, direct substitutes with active product status are RMCF0603FT2K20 (Stackpole Electronics Inc), ERJ-3EKF2201V (Panasonic Electronic Components), and CRCW06032K20FKEA (Vishay Dale). These parts maintain full compliance with automotive standards and are currently in active production with substantial inventory availability.

ERJ-S03F2201V (Panasonic Electronic Components) provides additional anti-sulfur protection while maintaining AEC-Q200 rating and active status, suitable for environments with corrosive exposure.

For applications where AEC-Q200 certification is not mandatory, CR0603-FX-2201ELF (Bourns Inc.), RC0603FR-072K2L (YAGEO), CRG0603F2K2 (TE Connectivity Passive Product), and RC1608F222CS (Samsung Electro-Mechanics) are functionally equivalent alternatives with moisture-resistant features and active production status. These parts maintain identical electrical specifications and 0603 package compatibility.

All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes, matching the regulatory profile of the original MCR03EZPFX2201.

Frequently Asked Questions (FAQ)

Q: Can RMCF0603FT2K20 directly replace MCR03EZPFX2201 in automotive applications?

A: Yes. RMCF0603FT2K20 meets all electrical parameters (2.2 kΩ ±1%, 0.1W), maintains the 0603 package, operates across -55°C to 155°C, and carries AEC-Q200 automotive qualification. It is currently in active production with high inventory availability.

Q: What is the difference between direct and similar substitutes?

A: Direct substitutes maintain AEC-Q200 automotive certification. Similar substitutes meet all core electrical and mechanical specifications but lack AEC-Q200 rating. Selection depends on whether automotive qualification is required for the application.

Q: Are there dimensional differences between substitute parts?

A: All parts use the 0603 (1608 Metric) package. Minor dimensional variations exist within tolerance: length ranges from 0.061" to 0.063" (1.55mm to 1.60mm), width from 0.031" to 0.033" (0.80mm to 0.85mm), and height from 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard PCB design tolerances and do not affect interchangeability.

Q: Which substitute offers the highest inventory availability?

A: RMCF0603FT2K20 (Stackpole Electronics Inc) has 377,750 pieces in stock, providing the highest availability among all substitutes while maintaining AEC-Q200 certification.

Q: Can I use CR0603-FX-2201ELF if my design requires AEC-Q200?

A: No. CR0603-FX-2201ELF is not AEC-Q200 rated. For automotive applications requiring this certification, select from RMCF0603FT2K20, ERJ-3EKF2201V, CRCW06032K20FKEA, or ERJ-S03F2201V.

Q: What additional features do some substitutes provide?

A: ERJ-S03F2201V includes anti-sulfur protection. CR0603-FX-2201ELF, RC0603FR-072K2L, and RC1608F222CS feature moisture-resistant construction. These enhancements do not affect basic electrical equivalence but may provide environmental protection benefits.
