Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX2204 is determined by strict equivalence across the following parameters:

• Resistance value: 2.2 MOhms
• 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
• Automotive qualification: AEC-Q200

All substitute parts listed below meet these electrical and mechanical specifications. Dimensional variations within supplier tolerances do not affect functional equivalence in standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

CRCW06032M20FKEA (Vishay Dale) is the primary direct substitute. It maintains full electrical and mechanical equivalence with AEC-Q200 automotive qualification and active product status. This part offers the highest inventory availability (28,862 pcs) and is supplied in Tape & Reel packaging for production environments.

AC0603FR-072M2L (YAGEO) is a qualified alternative with active status, AEC-Q200 rating, and ROHS3 compliance. It includes moisture-resistant construction and MSL 1 rating. Inventory availability is 17,312 pcs.

RC0603FR-072M2L (YAGEO) is functionally equivalent with active status and the highest inventory availability (301,604 pcs). This part does not specify AEC-Q200 automotive qualification. It is suitable for non-automotive applications or where automotive qualification is not a design requirement.

Frequently Asked Questions (FAQ)

Q: Can CRCW06032M20FKEA directly replace MCR03EZPFX2204 in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, share identical electrical specifications (2.2 MOhms ±1%, 0.1W), and use the same 0603 package. No circuit redesign is required.

Q: What is the difference between AC0603FR-072M2L and RC0603FR-072M2L?

A: Both are YAGEO 2.2 MOhms ±1% 0.1W 0603 resistors with identical electrical performance. AC0603FR-072M2L specifies AEC-Q200 automotive qualification; RC0603FR-072M2L does not. AC0603FR-072M2L is preferred for automotive designs.

Q: Are dimensional variations between substitutes significant?

A: Dimensional differences (length 1.55mm to 1.60mm, height 0.50mm to 0.55mm) fall within standard PCB assembly tolerances and do not affect functionality or placement in standard 0603 footprints.

Q: Which substitute offers the best inventory availability?

A: RC0603FR-072M2L has the highest stock level at 301,604 pcs. For automotive-qualified inventory, CRCW06032M20FKEA is available with 28,862 pcs.

Q: Can RC0603FR-072M2L be used in automotive applications?

A: RC0603FR-072M2L meets the electrical and thermal specifications required for automotive use but does not carry explicit AEC-Q200 qualification. Design requirements determine whether this qualification is mandatory.
