Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCR03EZPFX23R2 is determined by strict equivalence across the following parameters: resistance value (23.2 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200). All identified substitute parts maintain these electrical and mechanical specifications, ensuring direct functional compatibility in automotive applications. Packaging format (Tape & Reel) and compliance certifications (ROHS3, REACH Unaffected) are consistent across all alternatives.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—CRCW060323R2FKEA (Vishay Dale), ERJ-3EKF23R2V (Panasonic), and RMCF0603FT23R2 (Stackpole)—are functionally equivalent to the MCR03EZPFX23R2 and maintain active product status. Each substitute meets AEC-Q200 automotive qualification, ROHS3 compliance, and identical electrical specifications. Selection among these alternatives should be based on availability, supply chain logistics, and established procurement relationships, as all three provide equivalent performance and reliability for automotive applications requiring 23.2 Ohm ±1% 0.1W thick film resistors in 0603 package format.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MCR03EZPFX23R2 with any of the listed substitutes? A: Yes. All listed substitutes maintain identical resistance (23.2 Ohms), tolerance (±1%), power rating (0.1W), package (0603), and automotive qualification (AEC-Q200). Direct substitution is electrically and mechanically compatible.

Q: Are there differences in physical dimensions between the main part and substitutes? A: Minor dimensional variations exist within acceptable tolerances. MCR03EZPFX23R2 and ERJ-3EKF23R2V measure 0.063" L × 0.031" W (1.60mm × 0.80mm). CRCW060323R2FKEA measures 0.061" L × 0.033" W (1.55mm × 0.85mm). RMCF0603FT23R2 measures 0.061" L × 0.031" W (1.55mm × 0.80mm). All fit standard 0603 footprints without modification.

Q: Do all substitutes carry the same automotive certifications? A: Yes. All parts are AEC-Q200 qualified, ROHS3 compliant, and REACH unaffected, meeting automotive industry standards.

Q: What is the difference between the substitute parts? A: All substitutes are electrically identical. Differences are limited to manufacturer, packaging format (all Tape & Reel), and minor physical dimensions. Selection depends on supply availability and procurement preferences.

Q: Is the temperature coefficient the same across all parts? A: Yes. All parts, including the main part and all substitutes, have a temperature coefficient of ±100ppm/°C and operate across -55°C to 155°C.
