MCR03EZPFX5603 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX5603 is a 560 kOhms ±1% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This thick film resistor meets automotive 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 from active manufacturers to maintain design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (560 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 RoHS3 compliance. Parts are grouped into three categories based on feature alignment:

Upgrade Category: KTR03EZPFX5603 (Rohm Semiconductor) — maintains all core parameters with addition of high voltage capability and active product status.

Direct Equivalents: CRCW0603560KFKEA (Vishay Dale), ERJ-3EKF5603V (Panasonic), RMCF0603FG560K (Stackpole), RMCF0603FT560K (Stackpole) — all parameters match the original part with AEC-Q200 automotive qualification.

Similar Alternatives: CR0603-FX-5603ELF (Bourns), RC0603FR-07560KL (YAGEO) — meet all core electrical and mechanical parameters with moisture-resistant composition instead of automotive AEC-Q200 rating.

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 compliance, select from the direct equivalent group: KTR03EZPFX5603 (Rohm), CRCW0603560KFKEA (Vishay Dale), ERJ-3EKF5603V (Panasonic), RMCF0603FG560K (Stackpole Cut Tape), or RMCF0603FT560K (Stackpole Tape & Reel). All maintain full compliance with the original specification and are in active production with established supply availability.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-5603ELF (Bourns) and RC0603FR-07560KL (YAGEO) provide functional equivalence with moisture-resistant composition. These alternatives offer significantly higher inventory levels and cost optimization potential.

Packaging format selection (Cut Tape, Tape & Reel, or Digi-Reel) depends on assembly process requirements and volume considerations. All listed substitutes maintain identical electrical performance and thermal characteristics across the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-5603ELF or RC0603FR-07560KL as direct replacements in automotive applications?

A: These parts meet all electrical and mechanical parameters but lack AEC-Q200 automotive qualification. Use only in non-automotive circuits or where automotive certification is not a design requirement.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Both packaging formats contain identical components. Cut Tape (CT) is suitable for lower-volume manual assembly or reel-to-reel processing. Tape & Reel (TR) is optimized for high-speed automated pick-and-place assembly. Selection depends on manufacturing process capability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed alternatives meet ROHS3 compliance and are REACH unaffected, matching the environmental regulatory status of the original MCR03EZPFX5603.

Q: Does the slight dimensional variation between manufacturers affect PCB layout?

A: Dimensional variations (length 1.55–1.60mm, width 0.80–0.85mm, height 0.50–0.55mm) are within standard 0603 package tolerance and do not require PCB layout modification. All parts are mechanically interchangeable on standard 0603 footprints.

Q: Which substitute offers the best supply availability?

A: RC0603FR-07560KL (YAGEO) has the highest inventory level at 221,493 pieces. For AEC-Q200 applications, ERJ-3EKF5603V (Panasonic) offers 99,733 pieces in stock.
