MCR03EZPFX3242 Equivalent & Substitute Parts
Part Overview
The MCR03EZPFX3242 is a 32.4 kOhms ±1% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This automotive-grade thick film resistor meets AEC-Q200 specifications and operates across -55°C to 155°C. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain the same electrical and mechanical characteristics for continued design support and production continuity.

Substitute Part Grouping Explanation
Substitution eligibility for the MCR03EZPFX3242 is determined by strict equivalence across the following parameters: resistance value (32.4 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 termination count (2). All identified substitute parts meet these core electrical and mechanical requirements. Packaging format (tape & reel, cut tape, or digi-reel) does not affect functional equivalence but may influence procurement and assembly workflows. Compliance certifications (RoHS3, REACH Unaffected, EAR99) are consistent across all alternatives.

Engineering Selection Recommendations
For applications requiring active product status and assured long-term availability, select from ERJ-3EKF3242V (Panasonic), CRCW060332K4FKEA (Vishay Dale), RMCF0603FT32K4 (Stackpole), CR0603-FX-3242ELF (Bourns), or RC0603FR-0732K4L (YAGEO). All five parts carry active product status and meet RoHS3 compliance and REACH unaffected designations.
For automotive applications requiring AEC-Q200 certification, select ERJ-3EKF3242V, CRCW060332K4FKEA, CRCW060332K4FKEB, or RMCF0603FT32K4. These parts explicitly carry AEC-Q200 ratings matching the original MCR03EZPFX3242 specification.
For high-volume procurement with tape & reel packaging, CRCW060332K4FKEB, RMCF0603FT32K4, and RC0603FR-0732K4L offer substantial inventory availability (69,558, 15,585, and 101,233 units respectively).
Frequently Asked Questions (FAQ)
Q: Can I substitute any of these parts directly into the MCR03EZPFX3242 footprint?
A: Yes. All substitute parts share identical 0603 (1608 Metric) package dimensions and 2-termination configuration. Physical footprint compatibility is assured across all alternatives.
Q: Does packaging format (tape & reel vs. cut tape) affect electrical performance?
A: No. Packaging format affects only procurement and assembly logistics. Electrical characteristics remain identical regardless of packaging method.
Q: Which substitute is best for automotive applications?
A: ERJ-3EKF3242V, CRCW060332K4FKEA, CRCW060332K4FKEB, and RMCF0603FT32K4 all carry AEC-Q200 automotive certification. Select based on availability, packaging preference, and product status requirements.
Q: Are all substitutes RoHS3 compliant?
A: Yes. All identified substitute parts carry ROHS3 Compliant status and REACH Unaffected designation, matching the original part's environmental compliance profile.
Q: What is the difference between active and discontinued product status?
A: Active parts are in current production with assured long-term availability. Discontinued parts may have limited remaining inventory and no guarantee of future supply. For new designs or long-term production, prioritize active status parts.
Q: Do moisture-resistant variants affect substitution eligibility?
A: Moisture resistance is an additional feature, not a substitution requirement. Parts with moisture-resistant designation (CR0603-FX-3242ELF, RC0603FR-0732K4L) are fully compatible with designs specified for standard thick film resistors.
