MCR01MZPJ2R2 Equivalent & Substitute Parts

Part Overview

The MCR01MZPJ2R2 is a 2.2 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 designed for automotive applications and meets AEC-Q200 qualification standards. The part is currently discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and production requirements.

Key Parameters

Parameter	Value
Resistance	2.2 Ohms
Tolerance	±5%
Power Rating	0.063W (1/16W)
Package	0402 (1005 Metric)
Composition	Thick Film
Operating Temperature Range	-55°C to 155°C
Compliance	ROHS3, REACH Unaffected

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Resistance Value: Must be 2.2 Ohms
Tolerance: ±5% or tighter (±1% acceptable as upgrade)
Power Rating: Minimum 0.063W (1/16W); higher ratings acceptable
Package: 0402 (1005 Metric) form factor required
Composition: Thick film technology
Operating Temperature: Must support -55°C to 155°C range
Compliance: ROHS3 and REACH status must match or exceed original

All listed substitute parts meet these core electrical and mechanical requirements. Differences in temperature coefficient, features (automotive rating), and product status are noted but do not prevent functional substitution within the specified parameter envelope.

Engineering Selection Recommendations

Direct Equivalents (Identical Specifications)

CRCW04022R20JNED and CR0402-J/-2R2GLF provide direct electrical and mechanical equivalence to MCR01MZPJ2R2. Both maintain 2.2 Ohm resistance, ±5% tolerance, 0.063W power rating, and identical temperature operating range. CRCW04022R20JNED carries automotive AEC-Q200 qualification matching the original part. Both are in active production status with established supply availability.

Upgraded Tolerance Option

CRCW04022R20FKED offers improved tolerance specification (±1% versus ±5%) while maintaining all other critical parameters including power rating, package, and operating temperature range. This part is suitable for applications requiring tighter resistance accuracy. Automotive AEC-Q200 qualification is retained.

Higher Power Rating Option

ERJ-2GEJ2R2X provides 0.1W power rating compared to the original 0.063W specification. This part maintains 2.2 Ohm resistance, ±5% tolerance, and automotive AEC-Q200 qualification. The increased power dissipation capability provides design margin for thermal considerations. Temperature coefficient range differs but operating temperature limits remain identical.

Moisture-Resistant Alternative

RC0402JR-072R2L from YAGEO provides moisture-resistant construction while maintaining core electrical specifications. This part matches the original 0.063W power rating and ±5% tolerance. Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) matches the original. Product status is active with high inventory availability.

All substitute parts maintain ROHS3 compliance and REACH unaffected status consistent with the original MCR01MZPJ2R2.

Frequently Asked Questions (FAQ)

Q: Can ERJ-2GEJ2R2X be used as a direct replacement despite the higher power rating?

A: Yes. The 0.1W power rating of ERJ-2GEJ2R2X exceeds the original 0.063W requirement. Higher power ratings do not prevent substitution; they provide additional thermal margin. All other critical parameters (resistance, tolerance, package, temperature range) are identical.

Q: What is the difference between CRCW04022R20FKED and CRCW04022R20JNED?

A: The primary difference is tolerance specification. CRCW04022R20FKED provides ±1% tolerance versus ±5% for CRCW04022R20JNED. Both maintain identical power rating (0.063W), package (0402), and automotive AEC-Q200 qualification. Selection depends on circuit accuracy requirements.

Q: Is RC0402JR-072R2L suitable for automotive applications?

A: RC0402JR-072R2L does not carry automotive AEC-Q200 qualification. It is specified as moisture-resistant thick film construction. For applications requiring automotive qualification, CRCW04022R20JNED or CRCW04022R20FKED are recommended alternatives.

Q: Do all substitute parts use the same 0402 package?

A: Yes. All listed substitute parts use the 0402 (1005 Metric) package with identical physical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and maximum seated height (0.016", 0.40mm). PCB footprints and assembly processes remain unchanged.

Q: What is the significance of temperature coefficient differences?

A: Temperature coefficient indicates resistance change over the operating temperature range. The original MCR01MZPJ2R2 specifies -250/+500 ppm/°C. Substitute parts show variations (±100 to ±200 ppm/°C for some options). These differences affect long-term stability in temperature-sensitive circuits but do not prevent substitution within the -55°C to 155°C operating envelope.

Q: Are all substitute parts currently in production?

A: Five of six substitute parts are in active production status. MCR01MZPJ2R2 (original) is discontinued at DiGi Electronics. For ongoing production requirements, active-status alternatives ensure supply chain continuity.
