MCR01MZPJ821 Equivalent & Substitute Parts

Part Overview

The MCR01MZPJ821 is an 820 Ohm ±5% thick film chip resistor in 0402 (1005 Metric) package rated for 0.063W (1/16W) 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 currently discontinued at DiGi Electronics, necessitating identification of equivalent alternatives that maintain the same electrical and mechanical specifications for continued design support and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: resistance value (820 Ohms), tolerance (±5%), power rating (0.063W minimum), package format (0402), composition (thick film), and operating temperature range (-55°C to 155°C). All substitute parts listed maintain these core specifications. Parts are grouped by substitution category based on additional compliance attributes and product status.

Direct Equivalents maintain identical electrical and mechanical specifications with active product status and full AEC-Q200 automotive qualification.

Upgrade Option provides superior tolerance (±1% vs ±5%) while maintaining all other specifications, suitable for applications requiring tighter resistance accuracy.

Similar Alternative meets all functional requirements with active status but lacks automotive AEC-Q200 certification, applicable for non-automotive applications.

Engineering Selection Recommendations

For Automotive Applications (AEC-Q200 Required): CRCW0402820RJNED (Vishay Dale) and RMCF0402JT820R (Stackpole Electronics Inc) are direct functional equivalents with active product status and full AEC-Q200 compliance. CRCW0402820RFKED (Vishay Dale) provides an upgrade path with ±1% tolerance while maintaining AEC-Q200 qualification and active availability.

For Non-Automotive Applications: RC0402JR-07820RL (YAGEO) and CR0402-JW-821GLF (Bourns Inc.) are functionally suitable alternatives with active status. These parts lack automotive certification but meet all electrical and mechanical requirements for general-purpose applications.

For Enhanced Accuracy Requirements: CRCW0402820RFKED offers superior tolerance specification (±1%) compared to the original ±5%, applicable when tighter resistance accuracy is required within automotive-qualified designs.

Power Rating Consideration: ERJ-2GEJ821X (Panasonic) provides higher power dissipation capability (0.1W vs 0.063W) while maintaining all other specifications, suitable for applications with increased thermal margin requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute MCR01MZPJ821 with any of these parts in automotive applications? A: Only CRCW0402820RJNED, RMCF0402JT820R, and CRCW0402820RFKED maintain AEC-Q200 automotive qualification. RC0402JR-07820RL and CR0402-JW-821GLF lack this certification and are not suitable for automotive designs requiring AEC-Q200 compliance.

Q: What is the difference between the direct equivalents? A: CRCW0402820RJNED and RMCF0402JT820R are electrically and mechanically identical to the original MCR01MZPJ821, differing only in manufacturer and temperature coefficient specification (±200ppm/°C vs ±100ppm/°C for RMCF). Both are active products with full AEC-Q200 qualification.

Q: Is CRCW0402820RFKED a direct replacement? A: CRCW0402820RFKED is functionally compatible but provides upgraded tolerance (±1% vs ±5%). It maintains the same package, power rating, and AEC-Q200 qualification. Use this part when design requirements specify tighter resistance tolerance.

Q: Why does ERJ-2GEJ821X have a different power rating? A: ERJ-2GEJ821X is rated for 0.1W (1/10W) compared to the original 0.063W (1/16W). This higher power rating provides additional thermal margin and is fully compatible with the original application. The higher rating does not create incompatibility.

Q: Are all substitute parts available in Tape & Reel packaging? A: Yes, all listed substitute parts are supplied in Tape & Reel (TR) packaging, matching the original MCR01MZPJ821 packaging format for automated assembly compatibility.

Q: What is the significance of RoHS3 compliance? A: All parts listed are ROHS3 compliant, meeting current environmental and hazardous substance restrictions. This ensures regulatory compliance for both automotive and general-purpose applications.
