MCR03EZPFX8662 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX8662 is an 86.6 kOhms ±1% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This automotive-grade thick film resistor meets AEC-Q200 qualification standards 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 MCR03EZPFX8662 is determined by strict equivalence across the following parameters:

Resistance value: 86.6 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.1W / 1/10W (exact match required)
Package: 0603 (1608 Metric) (exact match required)
Composition: Thick Film (exact match required)
Temperature coefficient: ±100ppm/°C (exact match required)
Operating temperature range: -55°C ~ 155°C (exact match required)
RoHS compliance: ROHS3 Compliant (exact match required)
Moisture sensitivity level: 1 (Unlimited) (exact match required)

All substitute parts listed below meet these criteria. Direct substitutes maintain automotive AEC-Q200 qualification. Similar substitutes meet all electrical and mechanical parameters but feature moisture-resistant composition instead of automotive-specific qualification.

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 qualification, select from direct substitutes: CRCW060386K6FKEA (Vishay Dale, active status, 38920 Pcs available), ERJ-3EKF8662V (Panasonic, active status, 1301 Pcs available), or RMCF0603FT86K6 (Stackpole, active status, 118084 Pcs available). RMCF0603FT86K6 offers the highest inventory availability.

For applications where automotive qualification is not mandatory, similar substitutes CR0603-FX-8662ELF (Bourns, 21282 Pcs) and RC0603FR-0786K6L (YAGEO, 334739 Pcs) provide equivalent electrical and mechanical performance with moisture-resistant composition. RC0603FR-0786K6L offers maximum inventory availability.

All candidates maintain ROHS3 compliance, MSL 1 rating, and identical electrical specifications. Selection should prioritize active product status and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-8662ELF or RC0603FR-0786K6L as direct replacements for MCR03EZPFX8662 in automotive applications?

A: CR0603-FX-8662ELF and RC0603FR-0786K6L are electrically and mechanically equivalent but feature moisture-resistant composition instead of automotive AEC-Q200 qualification. Use only if your application does not require AEC-Q200 certification. For automotive-qualified designs, select CRCW060386K6FKEA, ERJ-3EKF8662V, or RMCF0603FT86K6.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All parts use the 0603 (1608 Metric) package with identical termination count (2). Physical dimensions vary slightly within tolerance (length 1.55–1.60mm, width 0.80–0.85mm, height 0.50–0.55mm), but all are compatible with standard 0603 PCB footprints.

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

A: Direct substitutes (CRCW060386K6FKEA, CRCW060386K6FKEB, ERJ-3EKF8662V, RMCF0603FT86K6) carry automotive AEC-Q200 qualification matching the original part. Similar substitutes (CR0603-FX-8662ELF, RC0603FR-0786K6L) meet all electrical and mechanical parameters but use moisture-resistant composition without automotive qualification.

Q: Which substitute offers the best supply availability?

A: RC0603FR-0786K6L (YAGEO) has the highest inventory at 334739 Pcs. For automotive-qualified parts, RMCF0603FT86K6 (Stackpole) offers 118084 Pcs.

Q: Do all substitutes meet RoHS and MSL requirements?

A: Yes. All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original MCR03EZPFX8662 specifications.
