Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX23R7 is determined by strict equivalence across the following parameters: resistance value (23.7 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional interchangeability in circuit applications.

The substitute parts are grouped into two categories:

Direct Substitutes (Automotive AEC-Q200 Rated): CRCW060323R7FKEA (Vishay Dale), ERJ-3EKF23R7V (Panasonic Electronic Components), and RMCF0603FT23R7 (Stackpole Electronics Inc) maintain full automotive qualification and identical electrical performance.

Similar Substitute (Moisture Resistant, Non-Automotive): RC0603FR-0723R7L (YAGEO) matches all electrical parameters and package specifications but features moisture-resistant construction instead of automotive AEC-Q200 certification. This part is suitable for applications where automotive qualification is not required.

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from CRCW060323R7FKEA, ERJ-3EKF23R7V, or RMCF0603FT23R7. All three maintain active product status with full automotive qualification and ROHS3 compliance. CRCW060323R7FKEA offers the highest inventory availability (33,353 pcs), followed by ERJ-3EKF23R7V (19,735 pcs) and RMCF0603FT23R7 (5,778 pcs).

For non-automotive applications where AEC-Q200 certification is not required, RC0603FR-0723R7L (YAGEO) provides an active alternative with moisture-resistant construction and the largest available inventory (187,266 pcs). This part maintains all electrical specifications and package compatibility while offering superior supply availability.

All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CRCW060323R7FKEA directly replace MCR03EZPFX23R7 in automotive circuits?

A: Yes. CRCW060323R7FKEA is a direct substitute with identical electrical parameters (23.7 Ohms ±1%, 0.1W), package type (0603), and AEC-Q200 automotive certification. The parts are functionally interchangeable.

Q: What is the difference between the Vishay Dale and Panasonic substitutes?

A: Both CRCW060323R7FKEA and ERJ-3EKF23R7V meet identical electrical and automotive specifications. The primary difference is physical dimension tolerance: CRCW060323R7FKEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" max height, while ERJ-3EKF23R7V measures 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" max height. Both are within 0603 package specification and suitable for standard PCB layouts.

Q: Is RC0603FR-0723R7L suitable for automotive applications?

A: RC0603FR-0723R7L is not AEC-Q200 rated and is classified as a similar substitute rather than a direct equivalent. It is suitable only for non-automotive applications. For automotive use, select CRCW060323R7FKEA, ERJ-3EKF23R7V, or RMCF0603FT23R7.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All listed substitutes, including the original MCR03EZPFX23R7, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute offers the best supply availability?

A: RC0603FR-0723R7L (YAGEO) has the highest inventory at 187,266 pcs. For automotive-qualified alternatives, CRCW060323R7FKEA (Vishay Dale) offers 33,353 pcs in stock.
