MCR03EZPFX1823 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX1823 is a 182 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 MCR03EZPFX1823 is determined by strict equivalence across the following parameters: resistance value (182 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 compliance standards (ROHS3, REACH Unaffected, EAR99).

Substitute parts are categorized into two groups:

Direct Substitutes maintain full automotive AEC-Q200 certification and identical electrical specifications. These parts are interchangeable without design modification.

Similar Substitutes meet all electrical and mechanical parameters but feature moisture-resistant composition instead of automotive AEC-Q200 rating. These parts are suitable for applications where automotive qualification is not mandatory.

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 certification, select from active parts with confirmed AEC-Q200 rating: CRCW0603182KFKEA (Vishay Dale), ERJ-3EKF1823V (Panasonic), RMCF0603FG182K (Stackpole), or RMCF0603FT182K (Stackpole). All four parts are currently in active production status with ROHS3 compliance and REACH Unaffected designation.

RMCF0603FT182K offers the highest inventory availability (1,217,426 units) in Tape & Reel packaging, suitable for high-volume production. ERJ-3EKF1823V provides strong availability (80,438 units) with Cut Tape & Digi-Reel packaging options.

For non-automotive applications where AEC-Q200 certification is not required, moisture-resistant alternatives CR0603-FX-1823ELF (Bourns), RC0603FR-07182KL (YAGEO), and RC1608F1823CS (Samsung) meet all electrical and mechanical specifications with active production status.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF1823 replace MCR03EZPFX1823 in automotive applications?

A: MCR03ERTF1823 matches all electrical parameters (182 kOhms ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C) but lacks documented AEC-Q200 certification. Use only in non-automotive applications or where automotive qualification is not specified.

Q: What is the difference between RMCF0603FT182K and RMCF0603FG182K?

A: Both parts are manufactured by Stackpole Electronics with identical electrical specifications and AEC-Q200 certification. RMCF0603FT182K is supplied in Tape & Reel packaging with significantly higher inventory (1,217,426 units). RMCF0603FG182K is supplied in Cut Tape packaging with lower inventory (7,311 units). Selection depends on production volume and packaging requirements.

Q: Are moisture-resistant variants suitable for automotive use?

A: CR0603-FX-1823ELF, RC0603FR-07182KL, and RC1608F1823CS meet all electrical and mechanical parameters but lack AEC-Q200 certification. These parts are suitable only for non-automotive applications or designs where automotive qualification is not mandatory.

Q: What packaging options are available?

A: Substitute parts are available in three packaging formats: Tape & Reel (TR) for high-volume production, Cut Tape (CT) for moderate volumes, and Cut Tape & Digi-Reel combinations for flexible ordering. RMCF0603FT182K in Tape & Reel format offers the largest inventory for continuous production.

Q: Do all substitutes maintain the same physical dimensions?

A: All parts conform to 0603 (1608 Metric) package specification. Dimensional variations exist within tolerance: most parts measure 0.063" L x 0.031" W (1.60mm x 0.80mm), while CRCW0603182KFKEA and RMCF0603FG182K measure 0.061" L x 0.031" W (1.55mm x 0.80mm). Height-seated maximum ranges from 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard PCB design tolerances.
