Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX26R1 is determined by strict equivalence across the following parameters:

• Resistance value: 26.1 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

Substitute parts are classified into two categories:

Direct Substitutes (AEC-Q200 Automotive Rated): CRCW060326R1FKEA (Vishay Dale), ERJ-3EKF26R1V (Panasonic Electronic Components), and RMCF0603FT26R1 (Stackpole Electronics Inc) meet all electrical and mechanical specifications with automotive AEC-Q200 certification.

Similar Substitute (Non-Automotive Rated): RC0603FR-0726R1L (YAGEO) meets all electrical and mechanical specifications but carries moisture-resistant designation instead of automotive AEC-Q200 rating.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive-grade components with AEC-Q200 certification, select from the direct substitutes: CRCW060326R1FKEA, ERJ-3EKF26R1V, or RMCF0603FT26R1. All three maintain full compliance with automotive standards and RoHS3 requirements.

The RC0603FR-0726R1L from YAGEO is suitable for non-automotive applications where AEC-Q200 certification is not required. This part maintains electrical and mechanical equivalence but lacks automotive qualification.

All substitute parts are currently in active production status with established supply availability, ensuring long-term component sourcing for design continuity.

Frequently Asked Questions (FAQ)

Q: Can I use RC0603FR-0726R1L in an automotive application originally designed for MCR03EZPFX26R1?

A: No. The MCR03EZPFX26R1 carries AEC-Q200 automotive certification. The RC0603FR-0726R1L does not have this rating. For automotive applications, use CRCW060326R1FKEA, ERJ-3EKF26R1V, or RMCF0603FT26R1.

Q: Are all substitute parts pin-compatible with the original MCR03EZPFX26R1?

A: Yes. All substitute parts use the 0603 (1608 Metric) package with 2 terminations, ensuring mechanical and electrical compatibility on PCB layouts designed for the original part.

Q: What is the difference between the direct substitutes?

A: CRCW060326R1FKEA, ERJ-3EKF26R1V, and RMCF0603FT26R1 are electrically and mechanically equivalent. Differences exist only in manufacturer series designation, physical dimensions within tolerance, and packaging format (all supplied as Tape & Reel). Selection may be based on supplier availability and lead time.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original MCR03EZPFX26R1 specifications.

Q: Why is the MCR03EZPFX26R1 discontinued?

A: Product discontinuation is determined by the manufacturer. Active alternatives from Vishay Dale, Panasonic Electronic Components, Stackpole Electronics Inc, and YAGEO provide equivalent functionality for ongoing production requirements.
