MCR03EZPFX3163 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX3163 is a 316 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 MCR03EZPFX3163 is determined by strict equivalence across the following parameters: resistance value (316 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 (AEC-Q200, ROHS3, REACH Unaffected).

Substitute parts are classified into two categories:

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

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

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from the direct substitute group: CRCW0603316KFKEA (Vishay Dale, active status, 30100 Pcs available), ERJ-3EKF3163V (Panasonic Electronic Components, active status, 57069 Pcs available), or RMCF0603FT316K (Stackpole Electronics Inc, active status, 218128 Pcs available). All three maintain full automotive qualification and identical electrical specifications to the original MCR03EZPFX3163.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-3163ELF (Bourns Inc.) and RC0603FR-07316KL (YAGEO) provide equivalent electrical performance with moisture-resistant construction. Both are in active production with substantial inventory availability.

All substitute parts are ROHS3 compliant, REACH unaffected, and maintain MSL 1 (unlimited) moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-3163ELF or RC0603FR-07316KL as direct replacements for MCR03EZPFX3163 in automotive applications?

A: No. CR0603-FX-3163ELF and RC0603FR-07316KL lack AEC-Q200 automotive qualification. Use these only in non-automotive applications. For automotive designs, select CRCW0603316KFKEA, ERJ-3EKF3163V, or RMCF0603FT316K.

Q: Are all substitute parts mechanically compatible with the original 0603 package footprint?

A: Yes. All substitute parts use the 0603 (1608 Metric) package. Minor dimensional variations exist (length 1.55mm to 1.60mm, width 0.80mm to 0.85mm, height 0.50mm to 0.55mm), but these fall within standard PCB design tolerances and do not affect footprint compatibility.

Q: What is the difference between CRCW0603316KFKEA and CRCW0603316KFKEB?

A: Both are Vishay Dale CRCW series 316 kOhms ±1% 0.1W 0603 resistors with identical electrical specifications and AEC-Q200 rating. The difference is packaging: CRCW0603316KFKEA is supplied in Cut Tape (CT) & Digi-Reel format (active status), while CRCW0603316KFKEB is supplied in Tape & Reel (TR) format (discontinued status).

Q: Which substitute offers the best inventory availability?

A: RMCF0603FT316K (Stackpole Electronics Inc) offers the highest inventory with 218128 Pcs available. RC0603FR-07316KL (YAGEO) provides 200006 Pcs for non-automotive applications.

Q: Do all parts meet the same temperature coefficient specification?

A: Yes. All substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, matching the original MCR03EZPFX3163 specification.
