Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCR03EZPFX2211 are qualified based on the following electrical and mechanical parameters:

• Resistance value: 2.21 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• Moisture Sensitivity Level: 1

Parts are classified as Direct substitutes when all parameters match exactly. Similar substitutes meet all electrical and mechanical requirements but may have different feature sets (such as moisture resistance designation) that do not affect core functionality within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical specifications of the MCR03EZPFX2211. Selection should be based on the following factors:

Direct Substitutes (Automotive AEC-Q200 rated):

• CRCW06032K21FKEA (Vishay Dale) - Active status, high inventory availability
• ERJ-3EKF2211V (Panasonic Electronic Components) - Active status, highest inventory availability
• RMCF0603FG2K21 (Stackpole Electronics Inc) - Active status, AEC-Q200 rated
• RMCF0603FT2K21 (Stackpole Electronics Inc) - Active status, highest inventory among Stackpole variants, AEC-Q200 rated

Similar Substitutes (Moisture Resistant, non-automotive rated):

• CR0603-FX-2211ELF (Bourns Inc.) - Active status, moisture resistant feature
• RC0603FR-072K21L (YAGEO) - Active status, moisture resistant feature

For applications requiring automotive AEC-Q200 compliance, select from the Direct Substitute group. For general industrial applications where AEC-Q200 is not mandatory, Similar Substitutes provide equivalent electrical performance with moisture resistance features.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-2211ELF or RC0603FR-072K21L as direct replacements for MCR03EZPFX2211?

A: These parts meet all electrical and mechanical parameters (2.21 kOhms ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C). However, they are not rated for automotive AEC-Q200 applications. Use them only in applications where AEC-Q200 certification is not required.

Q: What is the difference between RMCF0603FG2K21 and RMCF0603FT2K21?

A: Both parts are manufactured by Stackpole Electronics Inc with identical electrical specifications (2.21 kOhms ±1%, 0.1W, 0603 package). The difference lies in packaging format and inventory availability. RMCF0603FT2K21 has significantly higher inventory stock.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original MCR03EZPFX2211 specifications.

Q: Can I mix different manufacturers' parts in the same assembly?

A: All substitute parts meet identical electrical and mechanical specifications. They are mechanically and electrically interchangeable within the same circuit design. Mixing manufacturers is acceptable from a functional standpoint.

Q: Which substitute has the best availability?

A: RMCF0603FT2K21 (Stackpole Electronics Inc) and ERJ-3EKF2211V (Panasonic Electronic Components) have the highest inventory levels among active parts.
