Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different tolerance in place of the MCR03EZPFX6042? A: No. The MCR03EZPFX6042 specifies ±1% tolerance. Substitute parts must maintain this exact tolerance to ensure circuit performance and compliance with design specifications.

Q: What is the difference between the MCR03EZPFX6042 and KTR03EZPF6042? A: Both parts are manufactured by Rohm Semiconductor and share identical electrical specifications (60.4 kΩ, ±1%, 0.1W, 0603 package). The KTR03EZPF6042 adds High Voltage capability and is currently in active production status, whereas the MCR03EZPFX6042 is discontinued. The KTR03EZPF6042 is supplied in Tape & Reel packaging.

Q: Are all substitute parts suitable for automotive applications? A: No. Only parts carrying AEC-Q200 rating are qualified for automotive applications. The MCR03EZPFX6042, KTR03EZPF6042, CRCW060360K4FKEA, ERJ-3EKF6042V, RMCF0603FG60K4, and RMCF0603FT60K4 carry AEC-Q200 certification. CR0603-FX-6042ELF and RC0603FR-0760K4L do not carry this rating.

Q: What packaging options are available for substitute parts? A: Substitute parts are available in three packaging formats: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel, and Bulk. Tape & Reel packaging is standard for automated assembly processes. Cut Tape & Digi-Reel options provide flexibility for mixed-volume orders.

Q: Do all substitute parts meet RoHS3 compliance? A: Yes. All listed substitute parts are ROHS3 Compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance profile of the MCR03EZPFX6042.

Q: Which substitute part has the highest inventory availability? A: RMCF0603FT60K4 from Stackpole Electronics Inc has the highest inventory with 340,761 units in stock, followed by ERJ-3EKF6042V from Panasonic Electronic Components with 215,249 units.
