Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX2873 is determined by strict equivalence across the following parameters: resistance value (287 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, REACH Unaffected, EAR99).

All substitute parts listed maintain identical electrical specifications and mechanical dimensions within the 0603 package footprint. Substitutes are categorized as direct equivalents when manufactured by different suppliers but meeting all specified parameters, or as similar alternatives when featuring additional properties such as moisture resistance or automotive AEC-Q200 certification.

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 certification, select from CRCW0603287KFKEA (Vishay Dale), ERJ-3EKF2873V (Panasonic Electronic Components), or RMCF0603FT287K (Stackpole Electronics Inc). All three are currently in active production status and maintain full AEC-Q200 compliance.

For general industrial applications where AEC-Q200 certification is not required, RC0603FR-07287KL (YAGEO) and CR0603-FX-2873ELF (Bourns Inc.) provide active alternatives with equivalent electrical and mechanical specifications. RC0603FR-07287KL features moisture-resistant construction; CR0603-FX-2873ELF also includes moisture-resistant properties.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification consistent with the original MCR03EZPFX2873.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF2873 directly replace MCR03EZPFX2873? A: MCR03ERTF2873 shares identical electrical specifications (287 kOhms, ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C) and 0603 package footprint. The primary difference is packaging format (Cut Tape & Digi-Reel versus standard packaging) and absence of AEC-Q200 rating. Direct substitution is electrically valid for non-automotive applications.

Q: Which substitute offers the best availability? A: ERJ-3EKF2873V (Panasonic Electronic Components) shows the highest inventory level at 196,528 pieces. RMCF0603FT287K (Stackpole Electronics Inc) provides 110,513 pieces. Both maintain active production status and AEC-Q200 certification.

Q: Are all substitutes compatible with the 0603 footprint? A: All listed substitutes use the 0603 (1608 Metric) package. Physical dimensions vary slightly within manufacturing tolerances: length ranges from 0.061" to 0.063" (1.55mm to 1.60mm), width from 0.031" to 0.033" (0.80mm to 0.85mm), and height from 0.020" to 0.022" (0.50mm to 0.55mm). These variations remain within standard PCB design tolerances for 0603 placement.

Q: What is the difference between AEC-Q200 and non-AEC-Q200 versions? A: AEC-Q200 certification indicates automotive-grade qualification with enhanced reliability testing. CRCW0603287KFKEA, ERJ-3EKF2873V, and RMCF0603FT287K carry this certification. Non-certified alternatives (MCR03ERTF2873, RC0603FR-07287KL, CR0603-FX-2873ELF) are suitable for industrial and consumer applications.

Q: Do moisture-resistant variants affect circuit performance? A: RC0603FR-07287KL and CR0603-FX-2873ELF feature moisture-resistant construction. This property does not alter electrical performance; it extends operational reliability in high-humidity environments. Electrical specifications remain identical across all substitutes.
