MCR03EZPFX1500 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX1500 is a 150 Ohm ±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, necessitating identification of functionally equivalent alternatives from active product lines that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX1500 is determined by strict equivalence across the following parameters: resistance value (150 Ohms), 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 compliance certifications (AEC-Q200, ROHS3, REACH Unaffected).

Substitute parts are categorized as follows:

Upgrade Substitutes maintain all electrical and mechanical parameters while offering enhanced features or improved product status. KTR03EZPF1500 from Rohm Semiconductor is an active product with high voltage capability.

Direct Substitutes provide complete parameter equivalence with active product status. CRCW0603150RFKEA and CRCW0603150RFKEB (Vishay Dale), ERJ-3EKF1500V (Panasonic), RMCF0603FG150R and RMCF0603FT150R (Stackpole Electronics) meet all electrical and mechanical requirements.

Similar Substitutes satisfy core electrical parameters and package requirements but may have minor feature variations. CR0603-FX-1500ELF (Bourns), CRG0603F150R (TE Connectivity), and RC0603FR-07150RL (YAGEO) are functionally compatible alternatives.

Engineering Selection Recommendations

For applications requiring strict AEC-Q200 automotive compliance, select from active products: KTR03EZPF1500 (Rohm Semiconductor), CRCW0603150RFKEA (Vishay Dale), ERJ-3EKF1500V (Panasonic), RMCF0603FG150R, or RMCF0603FT150R (Stackpole Electronics). All maintain full parameter equivalence with the discontinued MCR03EZPFX1500 and carry current product status with established supply chains.

For non-automotive applications or where AEC-Q200 certification is not mandatory, CR0603-FX-1500ELF (Bourns), CRG0603F150R (TE Connectivity), and RC0603FR-07150RL (YAGEO) provide electrical and mechanical compatibility with active availability.

All substitute candidates are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MCR03EZPFX1500 with any of the listed substitutes?

A: Direct replacement is possible only with parts matching all electrical parameters (150 Ω, ±1%, 0.1W) and package specification (0603). All listed substitutes meet these criteria. For automotive applications, prioritize parts with active AEC-Q200 certification.

Q: What is the difference between upgrade and direct substitutes?

A: Upgrade substitutes (KTR03EZPF1500) offer additional features such as high voltage capability while maintaining core specifications. Direct substitutes provide complete parameter equivalence without feature enhancement. Both are functionally interchangeable for the original application.

Q: Does packaging format affect substitution?

A: Packaging format (Tape & Reel vs. Cut Tape) does not affect electrical or mechanical compatibility. Selection should be based on assembly process requirements and inventory management practices.

Q: Are similar substitutes without AEC-Q200 rating acceptable?

A: Similar substitutes lacking AEC-Q200 certification are electrically and mechanically equivalent but do not carry automotive qualification. Use only in applications where automotive compliance is not required.

Q: What parameters must remain constant for substitution?

A: Resistance value (150 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C) must remain unchanged for functional equivalence.
