MCR03EZPFX1583 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX1583 is a 158 kOhms ±1% 0.1W thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This component is rated for automotive applications under AEC-Q200 standard with an operating temperature range of -55°C to 155°C. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX1583 is determined by strict equivalence across the following parameters: resistance value (158 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 two categories based on automotive certification status.

Direct Substitutes (AEC-Q200 Rated): CRCW0603158KFKEA, ERJ-3EKF1583V, and RMCF0603FT158K meet all electrical and mechanical specifications with automotive AEC-Q200 qualification.

Similar Substitutes (Moisture Resistant, Non-Automotive Rated): CR0603-FX-1583ELF and RC0603FR-07158KL match all core electrical parameters and package specifications but feature moisture-resistant construction without automotive AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 certification, select from CRCW0603158KFKEA (Vishay Dale), ERJ-3EKF1583V (Panasonic), or RMCF0603FT158K (Stackpole). All three parts are currently in active production with full automotive qualification and equivalent electrical performance to the discontinued MCR03EZPFX1583.

For non-automotive applications or where moisture-resistant construction is prioritized, CR0603-FX-1583ELF (Bourns) and RC0603FR-07158KL (YAGEO) provide equivalent electrical specifications with moisture-resistant thick film construction. These parts are not rated for automotive use and should not be substituted in automotive circuits.

Selection between AEC-Q200 qualified parts should be based on availability, packaging preference (Cut Tape vs. Tape & Reel), and supply chain considerations. All qualified substitutes are electrically and mechanically interchangeable with the original MCR03EZPFX1583.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-1583ELF or RC0603FR-07158KL in an automotive application?

A: No. These parts lack AEC-Q200 automotive certification. They are suitable only for non-automotive applications. For automotive circuits, use CRCW0603158KFKEA, ERJ-3EKF1583V, or RMCF0603FT158K.

Q: Are all substitute parts physically identical to the MCR03EZPFX1583?

A: All substitutes use the 0603 (1608 Metric) package with identical electrical specifications. Minor dimensional variations exist within tolerance (height ranges from 0.50mm to 0.55mm, length from 1.55mm to 1.60mm), but these do not affect PCB assembly compatibility.

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

A: Cut Tape (CT) packaging is suitable for small-quantity orders and manual assembly. Tape & Reel (TR) packaging is optimized for high-volume automated assembly. Electrical performance is identical; selection depends on production volume and assembly process.

Q: Do all substitutes meet RoHS3 compliance?

A: Yes. All listed substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original part's environmental compliance profile.

Q: Which substitute has the highest inventory availability?

A: ERJ-3EKF1583V (Panasonic) has 99,051 pieces in stock, followed by RC0603FR-07158KL (YAGEO) with 40,027 pieces and RMCF0603FT158K (Stackpole) with 37,206 pieces.
