MCR01MZPJ910 Equivalent & Substitute Parts

Part Overview

The MCR01MZPJ910 is a 91 Ohm ±5% 1/16W (0.063W) thick film chip resistor in 0402 (1005 Metric) package manufactured by Rohm Semiconductor. This automotive-grade component meets AEC-Q200 specifications 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 the same electrical and mechanical characteristics.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (91 Ohms), tolerance (±5%), power rating (0.063W/1/16W), package type (0402), composition (thick film), operating temperature range (-55°C to 155°C), and RoHS3 compliance. Parts are grouped into three categories based on additional attributes:

Direct Equivalents maintain all key parameters including tolerance, power rating, and package specifications. These parts are interchangeable without design modification.

Upgrade Options provide enhanced specifications (tighter tolerance or higher power rating) while maintaining the same package and core electrical characteristics. These may be used where improved performance is acceptable.

Similar Alternatives match all critical electrical and mechanical parameters but may differ in secondary attributes such as temperature coefficient or specific manufacturer features, provided they remain within acceptable operating ranges.

Engineering Selection Recommendations

For direct replacement with maintained specifications: CRCW040291R0JNED (Vishay Dale) is the primary recommendation. This part maintains all electrical parameters of the MCR01MZPJ910, retains AEC-Q200 automotive certification, and is currently in active production with substantial inventory availability (20,123 pcs).

For automotive applications requiring AEC-Q200 compliance: Both CRCW040291R0JNED and ERJ-2GEJ910X meet automotive qualification requirements. ERJ-2GEJ910X provides higher power rating (0.1W vs. 0.063W) and exceptional inventory depth (343,951 pcs), making it suitable where thermal margin is beneficial.

For general-purpose applications without automotive requirements: RC0402JR-0791RL (YAGEO) and CR0402-JW-910GLF (Bourns) provide active alternatives with equivalent electrical performance. Both maintain RoHS3 compliance and standard operating temperature ranges.

For enhanced tolerance specifications: CRCW040291R0FKED (Vishay Dale) offers ±1% tolerance with AEC-Q200 certification, suitable for applications requiring tighter resistance accuracy. This represents an upgrade path maintaining the same package and power rating.

Frequently Asked Questions (FAQ)

Q: Can MCR01MRTJ910 directly replace MCR01MZPJ910? A: MCR01MRTJ910 matches all electrical specifications (91 Ω, ±5%, 0.063W, 0402 package, ±200ppm/°C, -55°C to 155°C). However, it lacks AEC-Q200 automotive certification present in the original part. Use only in non-automotive applications or where automotive qualification is not required.

Q: Is ERJ-2GEJ910X a suitable substitute despite higher power rating? A: Yes. The 0.1W power rating of ERJ-2GEJ910X exceeds the 0.063W requirement, providing additional thermal margin without affecting circuit operation. All other parameters match: 91 Ω resistance, ±5% tolerance, 0402 package, ±200ppm/°C temperature coefficient, and AEC-Q200 certification. Higher power rating does not create incompatibility.

Q: What is the difference between CRCW040291R0JNED and CRCW040291R0FKED? A: CRCW040291R0JNED provides ±5% tolerance with ±200ppm/°C temperature coefficient. CRCW040291R0FKED offers tighter ±1% tolerance with ±100ppm/°C temperature coefficient. Both maintain 0.063W power rating, 0402 package, and AEC-Q200 certification. Select FKED variant where circuit design requires tighter resistance accuracy.

Q: Are YAGEO and Bourns alternatives suitable for automotive applications? A: RC0402JR-0791RL (YAGEO) and CR0402-JW-910GLF (Bourns) lack AEC-Q200 automotive certification. These parts are suitable for consumer and industrial applications but should not be used in automotive designs requiring AEC-Q200 compliance. For automotive applications, use CRCW040291R0JNED or ERJ-2GEJ910X.

Q: Does package compatibility extend beyond 0402? A: All listed substitutes use 0402 (1005 Metric) package. This package is not interchangeable with other sizes (0201, 0603, 0805, etc.). Verify PCB footprint matches 0402 specifications before component selection.

Q: What is the significance of temperature coefficient differences? A: MCR01MZPJ910 specifies ±200ppm/°C. RC0402JR-0791RL and CRCW040291R0FKED specify ±100ppm/°C (tighter). Lower temperature coefficient indicates better resistance stability across temperature extremes. Both values remain acceptable for standard applications; select tighter coefficient where temperature-sensitive circuits require enhanced stability.
