Equivalent & Substitute Parts for MCR01MZPJ305

Part Overview

The MCR01MZPJ305 is a 3 MOhms ±5% thick film chip resistor in 0402 (1005 Metric) package rated for 1/16W (0.063W) power dissipation. Manufactured by Rohm Semiconductor, this component is qualified to automotive AEC-Q200 standards and operates across -55°C to 155°C. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

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

Direct Substitutes (Identical Electrical & Mechanical Specifications):

Resistance: 3 MOhms
Tolerance: ±5%
Power Rating: 0.063W (1/16W)
Package: 0402 (1005 Metric)
Temperature Range: -55°C ~ 155°C
Composition: Thick Film

Parts meeting all these criteria are electrically and mechanically interchangeable with MCR01MZPJ305 in standard applications.

Functional Equivalents (Higher Power Rating):

ERJ-2GEJ305X: Rated 0.1W (1/10W) instead of 0.063W. All other parameters identical. Provides additional thermal margin in the same package footprint.

Upgrade Substitutes (Improved Tolerance):

CRCW04023M00FKED: Tolerance ±1% versus ±5%. All other parameters identical. Suitable where tighter tolerance specification is required.

Engineering Selection Recommendations

For Direct Replacement (Automotive Applications): CRCW04023M00JNED and RMCF0402JT3M00 are preferred direct substitutes. Both maintain AEC-Q200 qualification, identical electrical specifications, and active product status. CRCW04023M00JNED offers higher inventory availability (20,789 pcs).

For Non-Automotive Applications: RC0402JR-073ML provides equivalent electrical performance with moisture-resistant composition and active status. Absence of AEC-Q200 rating is acceptable where automotive qualification is not required.

For Enhanced Thermal Performance: ERJ-2GEJ305X offers 0.1W power rating in the same 0402 package, providing additional thermal margin while maintaining all other specifications and AEC-Q200 compliance.

For Tighter Tolerance Requirements: CRCW04023M00FKED upgrades tolerance to ±1% with improved temperature coefficient (±100ppm/°C) and maintains AEC-Q200 qualification and active status.

Frequently Asked Questions (FAQ)

Q: Can MCR01MRTJ305 replace MCR01MZPJ305? A: MCR01MRTJ305 is electrically and mechanically identical but lacks AEC-Q200 automotive qualification. It is suitable only for non-automotive applications. Both parts are discontinued.

Q: What is the difference between CRCW04023M00JNED and RMCF0402JT3M00? A: Both are direct electrical and mechanical equivalents with AEC-Q200 qualification and active status. Selection depends on packaging preference (Tape & Reel vs. Cut Tape & Digi-Reel) and supplier availability.

Q: Can ERJ-2GEJ305X be used as a direct substitute? A: ERJ-2GEJ305X is mechanically compatible and electrically equivalent in resistance, tolerance, and temperature range. The 0.1W power rating exceeds the original 0.063W specification, providing additional thermal headroom. Temperature coefficient differs (-400/+150ppm/°C vs. ±200ppm/°C). Suitable for applications where higher power dissipation capability is acceptable.

Q: Is RC0402JR-073ML suitable for automotive applications? A: RC0402JR-073ML lacks AEC-Q200 qualification and is not suitable for automotive applications requiring this certification. It is appropriate for consumer and industrial applications.

Q: What does ±5% tolerance mean for a 3 MOhms resistor? A: A 3 MOhms resistor with ±5% tolerance will measure between 2.85 MOhms and 3.15 MOhms at 25°C. CRCW04023M00FKED with ±1% tolerance will measure between 2.97 MOhms and 3.03 MOhms.

Q: Are all substitutes RoHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited).
