MCR03EZPFX1072 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX1072 is a 10.7 kOhms ±1% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This automotive-grade thick film resistor features AEC-Q200 qualification and operates across -55°C to 155°C. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain the same electrical and mechanical specifications for continued system support and new designs.

Substitute Part Grouping Explanation

Substitute parts for the MCR03EZPFX1072 are qualified based on strict equivalence across the following critical parameters:

Resistance value: 10.7 kOhms
Tolerance: ±1%
Power rating: 0.1W (1/10W)
Package: 0603 (1608 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
Number of terminations: 2
RoHS3 compliance
MSL rating: 1 (Unlimited)

All identified substitutes meet these core electrical and mechanical requirements. Variations in packaging format (Tape & Reel vs. bulk), product status (Active vs. Discontinued), and specific feature designations (Automotive AEC-Q200, Anti-Sulfur, Moisture Resistant) do not affect functional interchangeability within the specified parameter envelope.

Engineering Selection Recommendations

For new designs and production continuity, the following parts are recommended based on product status and compliance:

Primary Selections (Active Status):

ERJ-3EKF1072V (Panasonic) — Active status with highest inventory availability (102,892 pcs)
RMCF0603FT10K7 (Stackpole) — Active status with extensive inventory (200,590 pcs)
RC0603FR-0710K7L (YAGEO) — Active status with high inventory (128,815 pcs)
CRCW060310K7FKEA (Vishay Dale) — Active status with automotive AEC-Q200 qualification (19,067 pcs)
CR0603-FX-1072ELF (Bourns) — Active status with moisture-resistant design (15,210 pcs)

Secondary Selections (Discontinued/Obsolete Status):

CRCW060310K7FKEB (Vishay Dale) — Discontinued at DiGi Electronics but available inventory (36,649 pcs)
TRR03EZPF1072 (Rohm) — Obsolete status but available inventory (10,857 pcs)

All listed substitutes maintain full electrical and mechanical equivalence to the MCR03EZPFX1072 across all specified parameters. Selection should prioritize active-status parts for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for MCR03EZPFX1072?

A: Yes. All listed parts meet the identical electrical specifications (10.7 kΩ ±1%, 0.1W, ±100ppm/°C) and mechanical requirements (0603 package, 2 terminations). They are functionally interchangeable within the specified parameter envelope.

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

A: Active parts are currently in production and available for new orders. Discontinued parts are no longer manufactured but may have existing inventory. For new designs, prioritize active-status parts to ensure long-term availability.

Q: Do the different feature designations (Automotive AEC-Q200, Anti-Sulfur, Moisture Resistant) affect substitution?

A: No. These designations describe additional qualifications or environmental protections but do not alter the core electrical or mechanical specifications. All parts meet the base parameter requirements for direct substitution.

Q: Are there any dimensional differences between these parts?

A: Minor dimensional variations exist within the 0603 package specification. All parts conform to the 0603 (1608 Metric) standard with maximum seated heights of 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard PCB assembly tolerances and do not affect interchangeability.

Q: Which substitute offers the best supply chain continuity?

A: RMCF0603FT10K7 (Stackpole) and RC0603FR-0710K7L (YAGEO) offer the highest inventory levels (200,590 and 128,815 pcs respectively) with active production status, providing optimal long-term availability.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the MCR03EZPFX1072 environmental compliance status.
