MCR03EZPFX16R9 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX16R9 is a 16.9 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, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX16R9 is determined by strict equivalence across the following critical parameters:

Resistance value: 16.9 Ohms
Tolerance: ±1%
Power rating: 0.1W (1/10W)
Package: 0603 (1608 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C
Termination count: 2
RoHS compliance: ROHS3 Compliant
Moisture sensitivity: MSL 1 (Unlimited)

All substitute parts listed meet these electrical and mechanical specifications. Automotive AEC-Q200 certification is present on the main part and most direct substitutes, though this rating is not a mandatory substitution criterion for general compatibility. The RC0603FR-0716R9L from YAGEO is classified as a similar part due to its moisture-resistant feature rather than automotive certification, but maintains full electrical and mechanical equivalence.

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive certification, select from CRCW060316R9FKEA (Vishay Dale), ERJ-3EKF16R9V (Panasonic), or RMCF0603FT16R9 (Stackpole Electronics). All three are currently in active production status with substantial inventory availability.

For general-purpose applications where automotive certification is not required, RC0603FR-0716R9L (YAGEO) provides an electrically and mechanically equivalent alternative with the highest inventory level (133,793 pieces) and active product status.

MCR03ERTF16R9 (Rohm Semiconductor) is electrically equivalent but shares discontinued status with the original part, making it unsuitable as a long-term substitute source.

Frequently Asked Questions (FAQ)

Q: Can I substitute MCR03EZPFX16R9 with any of the listed parts?

A: All listed parts are electrically and mechanically equivalent based on resistance, tolerance, power rating, package type, temperature coefficient, and operating temperature range. Physical dimensions and termination count are identical or within acceptable tolerances for PCB assembly.

Q: What is the difference between direct substitutes and similar parts?

A: Direct substitutes (MCR03ERTF16R9, CRCW060316R9FKEA, ERJ-3EKF16R9V, RMCF0603FT16R9) maintain full specification equivalence including AEC-Q200 automotive certification where applicable. RC0603FR-0716R9L is classified as a similar part because it lacks AEC-Q200 certification but maintains all electrical and mechanical specifications.

Q: Does package size vary between substitutes?

A: All substitutes use the 0603 (1608 Metric) package. Minor dimensional variations exist (length 0.061" to 0.063", width 0.031" to 0.033", height 0.020" to 0.022"), but these fall within standard PCB design tolerances and do not affect interchangeability.

Q: Which substitute has the best availability?

A: RC0603FR-0716R9L (YAGEO) has the highest inventory level at 133,793 pieces. Among AEC-Q200 certified alternatives, ERJ-3EKF16R9V (Panasonic) has 94,411 pieces in stock.

Q: Are all substitutes RoHS3 compliant?

A: Yes, all listed substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part specifications.
