MCR03EZPFX2872 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX2872 is a 28.7 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 MCR03EZPFX2872 is determined by strict equivalence across the following parameters: resistance value (28.7 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 certifications (RoHS3, REACH Unaffected, EAR99).

Parts are classified into two categories:

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

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

Engineering Selection Recommendations

For applications requiring strict AEC-Q200 automotive compliance, select from the direct substitutes: CRCW060328K7FKEA (Vishay Dale), ERJ-3EKF2872V (Panasonic Electronic Components), RMCF0603FG28K7 (Stackpole Electronics Inc), or RMCF0603FT28K7 (Stackpole Electronics Inc). All direct substitutes maintain identical electrical specifications and automotive qualification.

RMCF0603FT28K7 offers the highest inventory availability at 200,238 pieces. ERJ-3EKF2872V provides 122,113 pieces in stock. Both are suitable for high-volume production requirements.

For applications where AEC-Q200 certification is not required but moisture resistance is beneficial, CR0603-FX-2872ELF (Bourns Inc.) and RC0603FR-0728K7L (YAGEO) are suitable alternatives. RC0603FR-0728K7L has the largest inventory at 425,321 pieces.

All substitute parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8533.21.0030).

Frequently Asked Questions (FAQ)

Q: Can I use a similar substitute part in place of a direct substitute? A: Similar substitute parts meet all electrical and mechanical parameters but lack explicit AEC-Q200 automotive qualification. Use similar substitutes only in applications where automotive qualification is not a design requirement.

Q: Are there dimensional differences between the main part and substitutes? A: Minor dimensional variations exist within acceptable tolerances. The MCR03EZPFX2872 and ERJ-3EKF2872V share identical dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm). Stackpole RMCF series parts measure 0.061" L x 0.031" W (1.55mm x 0.80mm). Vishay CRCW060328K7FKEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm). All variants fit the 0603 package footprint and are mechanically compatible.

Q: What is the difference between RMCF0603FG28K7 and RMCF0603FT28K7? A: Both parts are identical in electrical specifications, resistance value, tolerance, power rating, and package. The difference lies in packaging format and inventory availability. RMCF0603FT28K7 has significantly higher stock (200,238 vs 10,933 pieces).

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts are RoHS3 compliant with moisture sensitivity level 1 (unlimited). All are REACH unaffected and classified as EAR99 for export control purposes.

Q: Can I mix different manufacturer parts in the same assembly? A: Yes. All direct substitute parts are electrically and mechanically equivalent and can be used interchangeably within the same design. Ensure procurement and quality documentation reflect the actual manufacturer part number used.
