MCR03EZPFX3651 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX3651 is a 3.65 kOhms ±1% 0.1W thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This automotive-grade component meets AEC-Q200 qualification standards and operates across -55°C to 155°C. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines or alternative manufacturers that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution validity for the MCR03EZPFX3651 is determined by strict equivalence across the following parameters: resistance value (3.65 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, MSL 1). All identified substitute parts maintain these specifications across different manufacturers and packaging formats. Substitutes are grouped by manufacturer and product status to facilitate procurement decisions based on availability and supply chain continuity.

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from active parts with explicit AEC-Q200 certification: CRCW06033K65FKEA (Vishay Dale), ERJ-3EKF3651V (Panasonic), RMCF0603FG3K65, or RMCF0603FT3K65 (Stackpole Electronics). All four maintain full compliance with the original specification and offer superior supply chain availability compared to discontinued alternatives.

For non-automotive applications where AEC-Q200 is not required, CR0603-FX-3651ELF (Bourns) and RC0603FR-073K65L (YAGEO) provide active product alternatives with identical electrical parameters and ROHS3 compliance.

MCR03ERTF3651 and TRR03EZPF3651 from Rohm Semiconductor are discontinued or obsolete and should not be selected for new designs despite electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can I substitute MCR03EZPFX3651 with any of the listed alternatives?

A: Direct substitution is valid only when all electrical parameters match: 3.65 kOhms resistance, ±1% tolerance, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. All listed parts meet these criteria. For automotive applications, AEC-Q200 certification is required; select CRCW06033K65FKEA, ERJ-3EKF3651V, RMCF0603FG3K65, or RMCF0603FT3K65.

Q: What is the difference between the Rohm MCR and TRR series?

A: MCR03EZPFX3651 carries AEC-Q200 automotive qualification. TRR03EZPF3651 features anti-sulfur thick film composition but lacks AEC-Q200 certification. Both are discontinued or obsolete; active alternatives are preferred.

Q: Are there packaging differences between substitutes?

A: All substitutes use 0603 (1608 Metric) package with identical footprint dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm). Minor height variations exist: MCR03EZPFX3651, TRR03EZPF3651, CR0603-FX-3651ELF, and RC0603FR-073K65L are 0.022" (0.55mm) maximum seated height; CRCW06033K65FKEA is 0.020" (0.50mm); RMCF variants are 0.022" (0.55mm). These differences do not affect PCB assembly compatibility.

Q: Which substitute offers the best supply availability?

A: RC0603FR-073K65L (YAGEO) has the highest inventory (342,735 pcs). ERJ-3EKF3651V (Panasonic) and CRCW06033K65FKEA (Vishay Dale) also maintain substantial stock levels (105,077 and 71,378 pcs respectively), ensuring reliable procurement.

Q: Do all substitutes meet RoHS and MSL requirements?

A: All listed substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original MCR03EZPFX3651 specification.
