Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX5111 is determined by strict equivalence across the following parameters: resistance value (5.11 kOhms), tolerance (±1%), power rating (0.1W), package type (0603/1608 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All identified substitute parts maintain these core electrical and mechanical specifications. Packaging format (Tape & Reel, Cut Tape, or Digi-Reel) does not affect functional equivalence but may impact procurement and assembly workflows. Compliance certifications (RoHS3, REACH status) and automotive ratings (AEC-Q200) are noted where applicable but do not preclude substitution based on electrical performance.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain electrical and mechanical equivalence to the MCR03EZPFX5111. Selection among active alternatives should prioritize product status and compliance requirements:

Preferred substitutes (Active status, ROHS3 compliant): CRCW06035K11FKEA, ERJ-3EKF5111V, RMCF0603FT5K11, CR0603-FX-5111ELF, RC0603FR-075K11L, and RC1608F5111CS are all currently active products with full ROHS3 compliance and equivalent electrical specifications.

Conditional substitute (Active status, RoHS non-compliant): CRCW06035K11FKTA is electrically equivalent but carries RoHS non-compliant status and REACH Affected designation. Use only where regulatory requirements permit.

Obsolete alternatives: TRR03EZPF5111 is obsolete and should not be selected for new designs despite electrical equivalence.

Packaging format selection (Tape & Reel, Cut Tape, or Digi-Reel) depends on assembly process requirements and does not affect circuit performance.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts directly for the MCR03EZPFX5111?

A: Yes, all listed active parts are electrically and mechanically equivalent. They share identical resistance (5.11 kOhms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). Substitution is valid from a functional standpoint.

Q: What is the difference between the packaging formats listed?

A: Tape & Reel, Cut Tape, and Digi-Reel are supply formats that affect procurement and automated assembly processes but do not impact electrical performance or circuit compatibility. Select based on your assembly equipment requirements.

Q: Why is CRCW06035K11FKTA marked as RoHS non-compliant?

A: CRCW06035K11FKTA carries RoHS non-compliant status and REACH Affected designation. This part is electrically equivalent but may not meet regulatory requirements for certain applications or markets. Verify compliance requirements before selection.

Q: Are there any automotive-rated alternatives?

A: The original MCR03EZPFX5111 carries AEC-Q200 automotive rating. Among active substitutes, CRCW06035K11FKEA, CRCW06035K11FKTA, ERJ-3EKF5111V, and RMCF0603FT5K11 are specified with AEC-Q200 features. Other active alternatives (CR0603-FX-5111ELF, RC0603FR-075K11L, RC1608F5111CS) are rated for moisture resistance but do not carry explicit AEC-Q200 designation.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All listed parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use these parts interchangeably in existing designs?

A: Yes. All substitute parts maintain the same electrical characteristics, package footprint (0603/1608 Metric), and thermal specifications. No circuit redesign or PCB layout modification is required.
