MCR03EZPFX3652 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX3652 is a 36.5 kOhms ±1% thick film chip resistor in 0603 (1608 Metric) package rated for 0.1W power dissipation. Manufactured by Rohm Semiconductor, this component meets Automotive AEC-Q200 specifications and operates across -55°C to 155°C. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers to maintain design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX3652 is determined by strict equivalence across the following parameters:

Resistance value: 36.5 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.1W minimum
Package: 0603 (1608 Metric) form factor
Composition: Thick film construction
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C minimum
RoHS3 compliance
MSL rating: 1 or better

Substitute parts are categorized as Direct equivalents when all parameters match the original specification. Similar parts meet all electrical and mechanical requirements but may differ in secondary features such as moisture resistance ratings or packaging format.

Engineering Selection Recommendations

For applications requiring Automotive AEC-Q200 certification, select from CRCW060336K5FKEA (Vishay Dale), ERJ-3EKF3652V (Panasonic), or RMCF0603FT36K5 (Stackpole Electronics). These parts maintain full compliance with the original specification including automotive-grade qualification.

RMCF0603FT36K5 offers the highest inventory availability (223,289 pieces) among AEC-Q200 qualified alternatives, supporting volume production requirements. ERJ-3EKF3652V provides 71,107 pieces in stock with equivalent automotive certification. CRCW060336K5FKEA supplies 38,081 pieces and is actively manufactured by Vishay Dale.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-3652ELF (Bourns) and RC0603FR-0736K5L (YAGEO) are functionally equivalent alternatives with active production status and substantial inventory levels.

MCR03ERTF3652 from Rohm Semiconductor is a direct electrical equivalent but is discontinued, making it unsuitable for new designs despite available inventory.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX3652 be replaced with any of these substitute parts in automotive applications?

A: Only CRCW060336K5FKEA, ERJ-3EKF3652V, and RMCF0603FT36K5 are suitable for automotive applications, as they carry AEC-Q200 certification matching the original part. Other substitutes lack this qualification.

Q: What is the difference between Direct and Similar substitute classifications?

A: Direct substitutes meet all electrical and mechanical parameters including automotive certification where applicable. Similar substitutes meet all core electrical and mechanical requirements but may lack automotive qualification or differ in secondary features such as moisture resistance ratings.

Q: Are there physical dimension differences between substitute parts?

A: All substitute parts use the 0603 (1608 Metric) package. Minor variations exist in seated height and length/width dimensions within standard 0603 tolerances. Verify specific PCB footprint requirements against individual datasheets if tight mechanical constraints apply.

Q: Can I use CR0603-FX-3652ELF or RC0603FR-0736K5L as direct replacements for the original MCR03EZPFX3652?

A: These parts are electrically and mechanically equivalent for non-automotive applications. However, they lack AEC-Q200 certification. If the original design required automotive qualification, these substitutes are not appropriate without design review and re-qualification.

Q: Which substitute offers the best supply chain stability?

A: RMCF0603FT36K5 from Stackpole Electronics provides the highest inventory level (223,289 pieces) with active production status, offering superior supply chain continuity for volume applications.

Q: Are all substitutes RoHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and meet REACH requirements, matching the environmental compliance profile of the original MCR03EZPFX3652.
