CRCW08053K90FKEC Equivalent & Substitute Parts

Part Overview

The CRCW08053K90FKEC is a 3.9 kOhms ±1% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by Vishay Dale. This component is rated for automotive applications under AEC-Q200 standard and operates across -55°C to 155°C. The part is currently active in production. Equivalent and substitute parts are necessary to address supply chain variations, packaging preferences, and manufacturer availability while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (3.9 kOhms), tolerance (±1%), power rating (0.125W), package type (0805 / 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3, REACH Unaffected, EAR99). All listed substitute parts meet these core electrical and mechanical requirements. Packaging format (Tape & Reel, Cut Tape, or Digi-Reel) and seated height variations do not affect functional substitutability. Automotive AEC-Q200 rating is present in most substitutes; parts without this designation remain electrically compatible but may require design review for automotive applications.

Engineering Selection Recommendations

All listed substitute parts maintain full electrical equivalence to the CRCW08053K90FKEC across resistance, tolerance, power rating, and temperature performance. For applications requiring automotive AEC-Q200 certification, select from CRCW08053K90FKEA, ERJ-6ENF3901V, RMCF0805FT3K90, or KTR10EZPF3901. All substitutes are RoHS3 compliant and REACH unaffected. The CRCW08053K90FKEAC and CR0805-FX-3901ELF variants lack AEC-Q200 rating but remain suitable for non-automotive applications. MCR10ERTF3901 is discontinued at DiGi Electronics and should not be selected for new designs. Packaging format selection (Tape & Reel versus Cut Tape & Digi-Reel) depends on assembly process requirements and does not affect electrical performance. Seated height variations (0.50mm to 0.70mm maximum) are within standard PCB design tolerances for 0805 components.

Frequently Asked Questions (FAQ)

Q: Can I substitute CRCW08053K90FKEA for CRCW08053K90FKEC? A: Yes. Both are Vishay Dale products with identical electrical specifications. The difference is packaging format: FKEC uses Tape & Reel while FKEA uses Cut Tape & Digi-Reel. Electrical performance is equivalent.

Q: Are all substitute parts AEC-Q200 rated? A: No. CRCW08053K90FKEAC, CR0805-FX-3901ELF, and MCR10ERTF3901 do not carry AEC-Q200 certification. For automotive applications, use CRCW08053K90FKEA, ERJ-6ENF3901V, RMCF0805FT3K90, or KTR10EZPF3901.

Q: Does the seated height difference affect PCB layout? A: No. All parts are 0805 (2012 Metric) package with maximum seated heights between 0.50mm and 0.70mm. These variations fall within standard PCB design clearances for this package class.

Q: Can I use MCR10ERTF3901 in a new design? A: MCR10ERTF3901 is discontinued at DiGi Electronics. For new designs, select from active alternatives: CRCW08053K90FKEA, ERJ-6ENF3901V, RMCF0805FT3K90, KTR10EZPF3901, CRCW08053K90FKEAC, or CR0805-FX-3901ELF.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging? A: Packaging format affects supply chain and assembly handling but not electrical performance. Tape & Reel is standard for high-volume automated assembly. Cut Tape & Digi-Reel accommodates lower-volume or mixed-component orders.

Q: Are all substitutes RoHS3 compliant? A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, matching the compliance profile of CRCW08053K90FKEC.
