Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX2103 is determined by strict equivalence across the following parameters: resistance value (210 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).

All identified substitute parts meet these core electrical and mechanical requirements. Substitute parts are categorized as follows:

Direct Substitutes (Automotive AEC-Q200 Rated): CRCW0603210KFKEA (Vishay Dale), ERJ-3EKF2103V (Panasonic Electronic Components), and RMCF0603FT210K (Stackpole Electronics Inc) maintain full automotive qualification and identical electrical specifications.

Similar Substitutes (Moisture Resistant, Non-Automotive Rated): CR0603-FX-2103ELF (Bourns Inc.), RC0603FR-07210KL (YAGEO), and RC1608F2103CS (Samsung Electro-Mechanics) provide equivalent electrical performance with moisture-resistant construction but do not carry AEC-Q200 automotive certification.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive qualification and AEC-Q200 compliance, select from the direct substitutes: CRCW0603210KFKEA, ERJ-3EKF2103V, or RMCF0603FT210K. All three are in active production with substantial inventory availability and maintain identical electrical and thermal specifications to the original MCR03EZPFX2103.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-2103ELF, RC0603FR-07210KL, and RC1608F2103CS provide equivalent electrical performance. Note that RC1608F2103CS is supplied in Cut Tape packaging rather than Tape & Reel, which may affect assembly process compatibility.

All substitute parts are RoHS3 compliant, REACH unaffected, and classified under EAR99 export control, matching the compliance profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can I use a non-AEC-Q200 rated substitute in an automotive application?

A: No. If the original design specifies AEC-Q200 compliance, only direct substitutes carrying AEC-Q200 certification (CRCW0603210KFKEA, ERJ-3EKF2103V, RMCF0603FT210K) are acceptable. Non-automotive rated parts do not meet automotive reliability and qualification standards.

Q: Are all substitute parts pin-compatible with the MCR03EZPFX2103?

A: Yes. All substitute parts use the 0603 (1608 Metric) package with two terminations, ensuring mechanical and electrical compatibility on PCB layouts designed for the original component.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape packaging is supplied in shorter tape segments, typically for lower-volume or manual assembly processes. RC1608F2103CS is the only substitute supplied in Cut Tape format.

Q: Do all substitutes have the same temperature coefficient?

A: Yes. All substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, ensuring thermal performance equivalence across the full operating envelope.

Q: Are there inventory differences between substitute options?

A: Yes. CRCW0603210KFKEA (Vishay Dale) has the highest inventory at 60,733 pieces, followed by ERJ-3EKF2103V (Panasonic) at 110,324 pieces and RMCF0603FT210K (Stackpole) at 80,013 pieces. RC1608F2103CS (Samsung) has the lowest inventory at 4,267 pieces.
