Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX4703 is determined by strict equivalence across the following parameters: resistance value (470 kOhms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). All substitute parts listed maintain these core electrical and mechanical specifications, ensuring direct functional compatibility in circuit applications.

The substitute parts are categorized as follows:

Upgrade Substitute: KTR03EZPF4703 (Rohm Semiconductor) — Active product with high voltage thick film composition and tape & reel packaging.

Direct Substitutes: CRCW0603470KFKEA (Vishay Dale), ERJ-3EKF4703V (Panasonic), RMCF0603FT470K (Stackpole Electronics) — All active products meeting identical electrical specifications.

Similar Substitutes: CR0603-FX-4703ELF (Bourns), CRG0603F470K (TE Connectivity), RC0603FR-07470KL (YAGEO) — Active products with equivalent core parameters; minor variations in physical dimensions and packaging formats.

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from KTR03EZPF4703 (Rohm), CRCW0603470KFKEA (Vishay Dale), ERJ-3EKF4703V (Panasonic), or RMCF0603FT470K (Stackpole Electronics). All four parts maintain active product status and full automotive compliance.

For non-automotive applications or where automotive qualification is not mandatory, CR0603-FX-4703ELF (Bourns), CRG0603F470K (TE Connectivity), and RC0603FR-07470KL (YAGEO) provide equivalent electrical performance with ROHS3 compliance and MSL 1 rating.

All substitute parts are ROHS3 compliant and carry MSL 1 moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage conditions. Selection between active substitutes should be based on packaging format preference (tape & reel versus cut tape) and supplier availability.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-4703ELF or CRG0603F470K as direct replacements for MCR03EZPFX4703 in automotive applications?

A: CR0603-FX-4703ELF and CRG0603F470K are not rated for AEC-Q200 automotive qualification. If your application requires automotive compliance, use KTR03EZPF4703, CRCW0603470KFKEA, ERJ-3EKF4703V, or RMCF0603FT470K instead.

Q: Are there physical dimension differences between these substitute parts?

A: All parts use the 0603 (1608 Metric) package. Minor variations exist in seated height and length/width dimensions (ranging from 1.55mm to 1.60mm length and 0.80mm to 0.85mm width). These variations are within standard 0603 package tolerances and do not affect PCB footprint compatibility.

Q: What is the difference between tape & reel and cut tape packaging?

A: Tape & reel packaging is supplied on continuous carrier tape for automated assembly equipment. Cut tape & Digi-Reel packaging provides smaller quantities on cut tape segments. Both formats are compatible with standard pick-and-place assembly processes; selection depends on production volume and equipment capability.

Q: Do all substitute parts meet ROHS3 and MSL 1 requirements?

A: Yes. All listed substitute parts are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity level) rating, ensuring compatibility with standard PCB assembly, storage, and handling procedures.

Q: Why is the MCR03EZPFX4703 discontinued?

A: The MCR03EZPFX4703 has been discontinued at DiGi Electronics. The upgrade substitute KTR03EZPF4703 from Rohm Semiconductor provides equivalent electrical specifications with active product status and improved availability.
