Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX8063 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 806 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Substitutes are categorized by product status and feature set:

Direct Substitutes (Rohm Semiconductor MCR Series): MCR03ERTF8063 maintains identical electrical and mechanical specifications with alternative packaging format.

Upgrade Option (Rohm Semiconductor KTR Series): KTR03EZPF8063 provides enhanced high-voltage capability while maintaining all core electrical parameters and AEC-Q200 qualification.

Cross-Manufacturer Direct Substitutes: CRCW0603806KFKEA (Vishay Dale), ERJ-3EKF8063V (Panasonic), RMCF0603FT806K (Stackpole Electronics) deliver equivalent performance with active product status and full AEC-Q200 compliance.

Cross-Manufacturer Similar Substitutes: CR0603-FX-8063ELF (Bourns) and RC0603FR-07806KL (YAGEO) provide functional equivalence with moisture-resistant features, suitable for applications where automotive AEC-Q200 certification is not mandatory.

Parameter Comparison

Engineering Selection Recommendations

For Automotive and High-Reliability Applications: Select KTR03EZPF8063, CRCW0603806KFKEA, ERJ-3EKF8063V, or RMCF0603FT806K. All four parts maintain AEC-Q200 qualification, active product status, and ROHS3 compliance. KTR03EZPF8063 offers the advantage of Rohm Semiconductor continuity with enhanced high-voltage capability. CRCW0603806KFKEA provides the highest inventory availability (33,823 pcs). ERJ-3EKF8063V offers superior stock depth (102,065 pcs) from Panasonic. RMCF0603FT806K delivers active status with substantial inventory (54,950 pcs) from Stackpole Electronics.

For General-Purpose Applications Where AEC-Q200 is Not Required: CR0603-FX-8063ELF (Bourns) and RC0603FR-07806KL (YAGEO) are suitable alternatives with moisture-resistant features and active product status. Both maintain full electrical and thermal specifications.

For Immediate Availability: ERJ-3EKF8063V provides the largest inventory reserve (102,065 pcs) with full automotive qualification and active status.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF8063 be used as a direct replacement for MCR03EZPFX8063?

A: MCR03ERTF8063 matches all electrical specifications (806 kOhms ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C ~ 155°C). However, the original part carries AEC-Q200 qualification while MCR03ERTF8063 does not. Both parts are discontinued at DiGi Electronics. For automotive applications requiring AEC-Q200 compliance, select an active substitute with automotive qualification.

Q: What is the difference between direct and similar substitutes?

A: Direct substitutes (KTR03EZPF8063, CRCW0603806KFKEA, ERJ-3EKF8063V, RMCF0603FT806K) maintain AEC-Q200 automotive qualification. Similar substitutes (CR0603-FX-8063ELF, RC0603FR-07806KL) meet all electrical and thermal parameters but lack automotive certification. Selection depends on application requirements.

Q: Are there mechanical differences between substitute parts?

A: All substitutes use the 0603 (1608 Metric) package. Minor dimensional variations exist: CRCW0603806KFKEA measures 0.061" L x 0.033" W with 0.020" max height; all others measure 0.063" L x 0.031" W with 0.022" max height. These variations are within standard 0603 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Which substitute offers the best long-term availability?

A: ERJ-3EKF8063V (Panasonic) maintains active product status with the highest inventory (102,065 pcs), indicating strong market support. CRCW0603806KFKEA (Vishay Dale) and RMCF0603FT806K (Stackpole Electronics) also maintain active status with substantial inventory reserves.

Q: Can CR0603-FX-8063ELF or RC0603FR-07806KL be used in automotive applications?

A: These parts lack AEC-Q200 qualification. Use them only in applications where automotive certification is not required. For automotive designs, select from KTR03EZPF8063, CRCW0603806KFKEA, ERJ-3EKF8063V, or RMCF0603FT806K.

Q: Are all substitutes RoHS3 compliant?

A: All identified substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part specifications.
