MCR03EZPFX1001 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX1001 is a 1 kOhms ±1% 0.1W thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This component meets Automotive AEC-Q200 qualification and operates across -55°C to 155°C. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Resistance value: 1 kOhms
Tolerance: ±1%
Power rating: 0.1W
Package: 0603 (1608 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
Automotive AEC-Q200 compliance
RoHS3 compliance
MSL rating: 1

Direct substitutes maintain all electrical and mechanical parameters. Upgrade substitutes offer improved tolerance (±0.5%) or enhanced features (high voltage capability) while preserving all core specifications. Packaging variants (Tape & Reel vs. Cut Tape) do not affect electrical equivalence.

Engineering Selection Recommendations

Direct Equivalents (Automotive AEC-Q200 Compliant, Active Status)

KTR03EZPF1001, CRCW06031K00FKEA, CRCW06031K00FKEC, CRCW06031K00FKEE, ERJ-3EKF1001V, RMCF0603FG1K00, and RMCF0603FT1K00 are direct functional equivalents. All maintain identical electrical specifications, AEC-Q200 qualification, and RoHS3 compliance. Selection among these parts should be based on packaging preference (Tape & Reel vs. Cut Tape) and inventory availability.

Automotive-Qualified Alternative

RCG06031K00FKEA provides electrical equivalence but lacks explicit AEC-Q200 designation in the provided specifications. Use only if automotive qualification is not a design requirement.

Upgrade Option

CRCW06031K00DHEAP offers improved tolerance (±0.5% vs. ±1%) and lower temperature coefficient (±50ppm/°C vs. ±100ppm/°C) while maintaining all other specifications. This part is suitable for applications requiring tighter tolerance control.

Discontinued Parts

CRCW06031K00FKEB and the original MCR03EZPFX1001 are discontinued at DiGi Electronics and should not be selected for new designs.

Frequently Asked Questions (FAQ)

Q: Can I substitute MCR03EZPFX1001 with any of the listed alternatives?

A: Direct substitutes are KTR03EZPF1001, CRCW06031K00FKEA, CRCW06031K00FKEC, CRCW06031K00FKEE, ERJ-3EKF1001V, RMCF0603FG1K00, and RMCF0603FT1K00. All maintain identical electrical and mechanical specifications with AEC-Q200 compliance. RCG06031K00FKEA is electrically equivalent but lacks documented AEC-Q200 rating.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Packaging format affects handling and assembly processes but does not alter electrical performance. Tape & Reel packaging is suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel packaging accommodates both manual and automated processes. Select based on manufacturing requirements.

Q: Can I use CRCW06031K00DHEAP as a direct replacement?

A: CRCW06031K00DHEAP is electrically compatible but offers improved specifications (±0.5% tolerance vs. ±1%, ±50ppm/°C vs. ±100ppm/°C). It is suitable as an upgrade substitute where tighter tolerance is beneficial or required. Verify design compatibility before implementation.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), matching the original MCR03EZPFX1001 specifications.

Q: Which substitute has the highest inventory availability?

A: ERJ-3EKF1001V (Panasonic) shows 631,200 pieces in stock, followed by RMCF0603FG1K00 (Stackpole) with 1,538,154 pieces. Both are active products with AEC-Q200 qualification.
