Substitute Part Grouping Explanation

Substitute parts for the MCR03EZPFX6492 are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes maintain full equivalence across all critical parameters:

Resistance value: 64.9 kOhms
Tolerance: ±1%
Power rating: 0.1W (1/10W)
Package: 0603 (1608 Metric)
Temperature coefficient: ±100ppm/°C
Operating temperature: -55°C ~ 155°C
RoHS3 compliance
MSL rating: 1 (Unlimited)

Similar Substitutes meet all electrical specifications and package requirements but differ in specific features (such as automotive AEC-Q200 certification or moisture resistance designation). These parts are functionally equivalent for applications where the specific feature set is not mandated.

Frequently Asked Questions (FAQ)

Q: Can CRCW060364K9FKEA directly replace MCR03EZPFX6492?

A: Yes. CRCW060364K9FKEA is a direct substitute. Both parts share identical resistance (64.9 kOhms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 certification. Physical dimensions are within acceptable tolerance for PCB assembly.

Q: What is the difference between CRCW060364K9FKEA and CRCW060364K9FKEB?

A: Both are Vishay Dale CRCW series 64.9 kOhms ±1% 0.1W 0603 resistors with AEC-Q200 certification. The primary difference is packaging: CRCW060364K9FKEA is supplied in Cut Tape (CT) & Digi-Reel® format, while CRCW060364K9FKEB is supplied in Tape & Reel (TR) format. CRCW060364K9FKEA has active product status, while CRCW060364K9FKEB is discontinued at DiGi Electronics.
