CRCW080591R0FKEBC Equivalent & Substitute Parts

Part Overview

The CRCW080591R0FKEBC is a 91 Ohm ±1% 1/8W thick film chip resistor in 0805 (2012 Metric) package manufactured by Vishay Dale. This component is currently active in production with 917 pieces in stock. The part is specified for general-purpose applications requiring precision resistive elements with stable performance across the -55°C to 155°C operating temperature range. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, inventory availability, or specific feature enhancements such as automotive qualification or moisture resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CRCW080591R0FKEBC are qualified based on strict electrical and mechanical parameter matching:

Electrical Parameters (Must Match):

• Resistance value: 91 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 0805 (2012 Metric)
• Size / Dimension: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitutes meet these core requirements. Variations in packaging format (Tape & Reel vs. Cut Tape), seated height tolerances, and optional features (moisture resistance, automotive qualification) are noted but do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Manufacturer): CRCW080591R0FKEAC (Vishay Dale) is a direct equivalent from the same manufacturer with identical electrical specifications, tolerance, power rating, and package dimensions. Both parts are active in production. This substitution is suitable for applications with no specific feature requirements beyond standard thick film resistor performance.

Cross-Manufacturer Substitutes (Active Status): CR0805-FX-91R0ELF (Bourns Inc.) and KTR10EZPF91R0 (Rohm Semiconductor) are active production parts meeting all core electrical and mechanical parameters. CR0805-FX-91R0ELF includes moisture-resistant construction, suitable for applications requiring enhanced environmental protection. KTR10EZPF91R0 carries AEC-Q200 automotive qualification and high-voltage rating, appropriate for automotive and high-reliability applications.

Discontinued Part: MCR10ERTF91R0 (Rohm Semiconductor) is discontinued at DiGi Electronics but remains electrically and mechanically compatible. This part is suitable only when existing inventory is available and long-term supply is not a constraint.

Compliance Verification: All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW080591R0FKEAC be used as a direct replacement for CRCW080591R0FKEBC? A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications (91 Ohms ±1%, 0.125W), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and 0805 package dimensions. The parts differ only in packaging format designation and are functionally interchangeable.

Q: What is the difference between the Bourns CR0805-FX-91R0ELF and the Vishay CRCW080591R0FKEBC? A: Both parts meet identical electrical and mechanical specifications. The CR0805-FX-91R0ELF includes moisture-resistant construction as an additional feature. Selection depends on application requirements for environmental protection. Both are active in production.

Q: Is the KTR10EZPF91R0 suitable for non-automotive applications? A: Yes. The KTR10EZPF91R0 meets all electrical and mechanical parameters of the CRCW080591R0FKEBC. The AEC-Q200 automotive qualification and high-voltage rating are additional features that do not restrict use in general-purpose applications. This part is suitable for any application requiring the specified 91 Ohm ±1% 0.125W resistor in 0805 package.

Q: Why is MCR10ERTF91R0 listed as discontinued? A: MCR10ERTF91R0 is discontinued at DiGi Electronics but remains electrically and mechanically compatible with CRCW080591R0FKEBC. Substitution is limited to applications where existing inventory is available. For new designs or long-term supply requirements, active production alternatives (CRCW080591R0FKEAC, CR0805-FX-91R0ELF, or KTR10EZPF91R0) are recommended.

Q: Are there package compatibility concerns between Tape & Reel and Cut Tape formats? A: No. Tape & Reel and Cut Tape formats are packaging and delivery methods only. The physical component dimensions, electrical specifications, and mechanical compatibility remain identical. Format selection is determined by assembly process requirements and inventory management, not by electrical or mechanical compatibility.

Q: Do all substitute parts comply with RoHS3 and MSL 1 requirements? A: Yes. All identified substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of CRCW080591R0FKEBC.
