RC0603FR-071M21L (YAGEO): Meets all core electrical and mechanical specifications. Active product status with highest inventory availability (464,301 pcs). Includes moisture-resistant feature. Suitable for applications where automotive AEC-Q200 certification is not mandatory. Packaging format is Tape & Reel (TR).

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF1214 be used as a direct replacement for MCR03EZPFX1214?

A: Yes. Both parts are from Rohm Semiconductor's MCR series with identical resistance, tolerance, power rating, package, and operating specifications. The primary difference is packaging format (Cut Tape & Digi-Reel vs. original packaging).

Q: What is the difference between CRCW06031M21FKEA and RC0603FR-071M21L?

A: Both parts meet the core electrical requirements (1.21 MOhms, ±1%, 0.1W, 0603 package). CRCW06031M21FKEA carries AEC-Q200 automotive certification; RC0603FR-071M21L includes moisture-resistant composition. Selection depends on whether automotive qualification is required for the application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts meet ROHS3 compliance requirements.

Q: What is the moisture sensitivity level for these parts?

A: All parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the PCB footprint accommodates the 0603 (1608 Metric) package. Physical dimensions are equivalent across all listed parts, with minor variations within tolerance (length 1.55–1.60mm, width 0.80–0.85mm, height 0.50–0.55mm seated).

Q: Which substitute offers the best long-term availability?

A: RC0603FR-071M21L (YAGEO) has the highest inventory level and active product status, ensuring sustained availability for production requirements.
