MCR03EZPFX4872 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX4872 is a 48.7 kOhms ±1% 0.1W thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers. Substitute parts must maintain identical electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (package size, termination count) to ensure direct board-level replacement without design modification.

Operating Temperature Range	-55°C ~ 155°C
Number of Terminations	2
RoHS Status	ROHS3 Compliant
Moisture Sensitivity Level	1 (Unlimited)

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Resistance value: 48.7 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.1W / 1/10W (exact match required)
Package: 0603 (1608 Metric) (exact match required)
Composition: Thick Film (exact match required)
Temperature coefficient: ±100ppm/°C (exact match required)
Operating temperature range: -55°C ~ 155°C (exact match required)
Termination count: 2 (exact match required)
RoHS compliance: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria. Variations in packaging format (bulk vs. Tape & Reel), manufacturer-specific features (Automotive AEC-Q200, Anti-Sulfur, Moisture Resistant), and minor dimensional tolerances do not affect functional substitutability.

Engineering Selection Recommendations

For new designs and production procurement, select from parts with Active product status to ensure long-term supply continuity and manufacturer support. CRCW060348K7FKEA (Vishay Dale), ERJ-3EKF4872V (Panasonic), RMCF0603FT48K7 (Stackpole), CR0603-FX-4872ELF (Bourns), and RC0603FR-0748K7L (YAGEO) are all suitable direct replacements.

For applications requiring Automotive AEC-Q200 certification, CRCW060348K7FKEA, ERJ-3EKF4872V, and RMCF0603FT48K7 meet this requirement. CR0603-FX-4872ELF and RC0603FR-0748K7L provide moisture-resistant thick film construction without automotive qualification.

All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental compliance profile.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX4872 be replaced with any of the listed substitute parts?

A: Yes. All listed parts are electrically and mechanically equivalent. They share identical resistance (48.7 kOhms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Direct substitution is possible without circuit modification.

Q: What is the difference between parts marked "Active" and "Discontinued" or "Obsolete"?

A: Active parts are currently manufactured and available from suppliers. Discontinued and Obsolete parts have limited or no future availability. For new production, select only Active parts to ensure supply chain reliability.

Q: Does packaging format (Tape & Reel vs. Bulk) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Are all substitute parts suitable for automotive applications?

A: Parts explicitly rated AEC-Q200 (CRCW060348K7FKEA, ERJ-3EKF4872V, RMCF0603FT48K7) meet automotive qualification standards. CR0603-FX-4872ELF and RC0603FR-0748K7L do not carry automotive certification but meet general industrial specifications.

Q: What does RoHS3 compliance mean?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All listed parts are RoHS3 compliant.

Q: Can dimensional variations between substitute parts affect PCB layout?

A: Dimensional variations are minimal (length 1.55–1.60mm, width 0.80–0.85mm, height 0.50–0.55mm). All parts fit standard 0603 footprints. Verify PCB design tolerances if tight spacing is critical, but standard designs accommodate all listed parts without modification.
