MCR50JZHJ621 Equivalent & Substitute Parts

Part Overview

The MCR50JZHJ621 is a 620 Ohms ±5% 0.5W thick film chip resistor in 2010 (5025 Metric) package 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, necessitating identification of functionally equivalent alternatives that maintain the same electrical and mechanical specifications for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR50JZHJ621 is determined by the following critical parameters:

• Resistance Value: Must be 620 Ohms
• Tolerance: Must be ±5%
• Package / Case: Must be 2010 (5025 Metric)
• Composition: Must be Thick Film
• Temperature Coefficient: Must be ±200ppm/°C
• Operating Temperature Range: Must be -55°C ~ 155°C
• Automotive Rating: Must be AEC-Q200 compliant
• RoHS Status: Must be ROHS3 Compliant

All identified substitute parts meet these core parameters. Power rating variations (0.75W vs. 0.5W) are acceptable in substitution as higher power ratings provide equivalent or superior thermal performance in the same package footprint, provided all other electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

For new production designs, RMCF2010JT620R (Stackpole Electronics Inc) is the primary recommended substitute. This part carries Active product status, ensuring long-term availability and supply chain stability. CRCW2010620RJNEF (Vishay Dale) is an alternative Active-status option with equivalent specifications.

ERJ-12ZYJ621U (Panasonic Electronic Components) is functionally equivalent but carries Not For New Designs status, making it suitable only for legacy system maintenance or repair applications where the original MCR50JZHJ621 is unavailable.

All three substitute parts maintain identical electrical performance, thermal characteristics, and automotive compliance ratings as the original MCR50JZHJ621. The higher power ratings (0.75W vs. 0.5W) in substitute parts provide thermal margin without affecting circuit functionality or footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010JT620R replace MCR50JZHJ621 in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified, share identical resistance (620 Ohms ±5%), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and 2010 package dimensions. The higher power rating (0.75W vs. 0.5W) does not affect compatibility.

Q: What is the difference between the substitute parts?

A: All three substitutes (ERJ-12ZYJ621U, CRCW2010620RJNEF, RMCF2010JT620R) meet identical electrical and mechanical specifications. The primary difference is product status: RMCF2010JT620R and CRCW2010620RJNEF are Active, while ERJ-12ZYJ621U is Not For New Designs.

Q: Are there any package or footprint differences?

A: No. All parts use the 2010 (5025 Metric) package with identical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.028" (0.70mm). PCB footprints are interchangeable.

Q: Is the higher power rating of substitute parts a concern?

A: No. Higher power ratings indicate improved thermal performance in the same package. This provides additional design margin and does not introduce compatibility issues.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts are ROHS3 Compliant with MSL Rating 1 (Unlimited), matching the original MCR50JZHJ621 specifications.
