MCR01MZPJ243 Equivalent & Substitute Parts

Part Overview

The MCR01MZPJ243 is a 24 kOhms ±5% thick film chip resistor in 0402 (1005 Metric) package rated for 1/16W (0.063W) power dissipation. Manufactured by Rohm Semiconductor as part of the MCR series, 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 continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the MCR01MZPJ243 is determined by the following critical parameters:

Primary Substitution Criteria:

Resistance value: 24 kOhms (exact match required)
Tolerance: ±5% or tighter (±1% acceptable as upgrade)
Power rating: 0.063W minimum (1/16W or higher acceptable)
Package: 0402 (1005 Metric) form factor (mandatory for PCB compatibility)
Composition: Thick film construction
Operating temperature range: -55°C to 155°C minimum
RoHS3 compliance required

Substitution Categories:

Direct Equivalents maintain all electrical and mechanical specifications identical to the main part, differing only in manufacturer or packaging format.

Upgrade Substitutes offer improved specifications (tighter tolerance, higher power rating, or enhanced temperature coefficient) while maintaining full backward compatibility.

Parts are grouped by functional equivalence and electrical interchangeability within the 0402 package constraint.

Engineering Selection Recommendations

For Automotive AEC-Q200 Applications: CRCW040224K0JNED, ERJ-2GEJ243X, and RMCF0402JT24K0 are qualified substitutes. CRCW040224K0JNED and ERJ-2GEJ243X maintain active product status with established supply chains. RMCF0402JT24K0 provides AEC-Q200 certification with improved temperature coefficient (±100ppm/°C).

For Enhanced Tolerance Requirements: CRCW040224K0FKED offers ±1% tolerance as an upgrade substitute, suitable for applications requiring tighter resistance accuracy. This part maintains AEC-Q200 qualification and active status.

For General Industrial Applications Without Automotive Requirements: RC0402JR-0724KL provides a functionally equivalent substitute with moisture-resistant construction and active availability. Temperature coefficient is ±100ppm/°C.

For Supply Chain Continuity: ERJ-2GEJ243X demonstrates the highest inventory availability (183,532 pcs) among active substitutes, supporting long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Can MCR01MRTJ243 replace MCR01MZPJ243 directly? A: Yes. MCR01MRTJ243 is a direct equivalent from Rohm Semiconductor with identical electrical specifications (24 kOhms ±5%, 0.063W, ±200ppm/°C). Both are 0402 package thick film resistors. The primary difference is packaging format (Cut Tape & Digi-Reel vs. original packaging) and both are discontinued at DiGi Electronics.

Q: What is the difference between the 0.063W and 0.1W power ratings? A: ERJ-2GEJ243X is rated for 0.1W (1/10W) versus the 0.063W (1/16W) specification of MCR01MZPJ243. The higher power rating provides additional thermal margin and is fully backward compatible for applications designed for 0.063W. No circuit redesign is required.

Q: Are non-AEC-Q200 parts acceptable substitutes? A: RC0402JR-0724KL and MCR01MRTJ243 lack AEC-Q200 certification. These are suitable only for non-automotive applications. For automotive designs requiring AEC-Q200 compliance, select from CRCW040224K0JNED, ERJ-2GEJ243X, RMCF0402JT24K0, or CRCW040224K0FKED.

Q: Does tolerance affect interchangeability? A: All listed substitutes maintain ±5% tolerance or tighter. CRCW040224K0FKED offers ±1% tolerance, which is tighter than the original ±5% specification and provides improved accuracy without compatibility issues.

Q: Are all substitutes in the same 0402 package? A: Yes. All listed substitutes use the 0402 (1005 Metric) package with identical footprint dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm). Direct PCB placement compatibility is confirmed.

Q: Which substitute has the best temperature coefficient? A: RMCF0402JT24K0 and CRCW040224K0FKED both offer ±100ppm/°C, compared to the original ±200ppm/°C. This represents improved temperature stability across the -55°C to 155°C operating range.
