Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX2871 is determined by strict equivalence across the following parameters:

Resistance value: 2.87 kOhms
Tolerance: ±1%
Power rating: 0.1W (1/10W)
Package: 0603 (1608 Metric)
Composition: Thick Film

Engineering Selection Recommendations

For applications requiring the MCR03EZPFX2871, the following selection criteria apply:

Active Status Priority: CRCW06032K87FKEA, ERJ-3EKF2871V, RC0603FR-072K87L, RMCF0603FT2K87, and CR0603-FX-2871ELF are all currently active products with established supply chains. MCR03ERTF2871 remains available but shares discontinued status with the original part.

Automotive AEC-Q200 Certification: CRCW06032K87FKEA, ERJ-3EKF2871V, and RMCF0603FT2K87 carry explicit AEC-Q200 automotive qualification. These are preferred for applications requiring automotive-grade reliability.

Moisture Resistance Feature: RC0603FR-072K87L and CR0603-FX-2871ELF include moisture-resistant construction, providing additional environmental protection in high-humidity or corrosive environments.

Supply Availability: ERJ-3EKF2871V (227,685 pcs), CRCW06032K87FKEA (35,832 pcs), and RC0603FR-072K87L (94,704 pcs) demonstrate the highest inventory levels, ensuring consistent availability for volume production.

All substitute parts maintain identical electrical specifications and RoHS3 compliance, ensuring direct functional replacement in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF2871 be used as a direct replacement for MCR03EZPFX2871?

A: Yes. Both parts are manufactured by Rohm Semiconductor with identical electrical specifications (2.87 kOhms ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C). The primary difference is packaging format (MCR03ERTF2871 is supplied in Cut Tape and Digi-Reel format versus the original part's packaging). Both are discontinued at DiGi Electronics.

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

A: ERJ-3EKF2871V from Panasonic Electronic Components is recommended for long-term availability, with over 227,000 units in stock and active product status. CRCW06032K87FKEA and RC0603FR-072K87L also maintain active status with substantial inventory levels.

Q: Are all substitutes suitable for automotive applications?

A: CRCW06032K87FKEA, ERJ-3EKF2871V, and RMCF0603FT2K87 carry AEC-Q200 automotive qualification. RC0603FR-072K87L and CR0603-FX-2871ELF do not list explicit automotive certification but meet all electrical and environmental specifications. Application requirements should determine whether AEC-Q200 certification is mandatory.

Q: Do physical dimension variations within the 0603 package affect PCB layout?

A: No. All parts conform to the 0603 (1608 Metric) package standard. Minor variations in length (0.061" to 0.063"), width (0.031" to 0.033"), and height (0.020" to 0.022") fall within standard 0603 tolerances and do not require PCB redesign.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All listed substitutes carry this rating, eliminating moisture sensitivity concerns during storage and handling.

Q: Can CR0603-FX-2871ELF replace MCR03EZPFX2871 in moisture-sensitive environments?

A: Yes. CR0603-FX-2871ELF includes moisture-resistant construction and maintains all required electrical specifications. This variant provides enhanced environmental protection while maintaining functional equivalence.
