CRCW0805523KFKEB Equivalent & Substitute Parts

Part Overview

The CRCW0805523KFKEB is a 523 kOhms ±1% 0.125W chip resistor in 0805 (2012 Metric) package manufactured by Vishay Dale. This thick film resistor is designed for automotive applications and meets AEC-Q200 qualification standards. The part is currently active in production with 970 pieces available in stock.

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or inventory depletion. Alternative manufacturers offering equivalent specifications ensure design continuity and production scheduling flexibility.

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW0805523KFKEB is determined by strict equivalence across the following parameters:

• Resistance value: 523 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package: 0805 (2012 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: MSL 1 (exact match required)

All substitute parts listed below meet these criteria. Variations in height-seated dimension and packaging format (Tape & Reel vs. Cut Tape) do not affect functional equivalence for PCB assembly applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

CRCW0805523KFKEA (Vishay Dale) is the direct equivalent from the same manufacturer with identical specifications and active production status. This part offers the highest compatibility assurance.

ERJ-6ENF5233V (Panasonic Electronic Components) and RMCF0805FT523K (Stackpole Electronics Inc) are functionally equivalent alternatives from established automotive-qualified manufacturers. Both parts maintain AEC-Q200 certification and ROHS3 compliance. Height variations (0.70mm and 0.65mm respectively, compared to 0.50mm for the primary part) are within standard PCB assembly tolerances and do not affect electrical performance or mechanical fit for 0805 package designs.

Secondary Substitute (Discontinued Status):

MCR10ERTF5233 (Rohm Semiconductor) is discontinued at DiGi Electronics and should be considered only when existing inventory is available and supply chain continuity is not a concern. This part lacks AEC-Q200 automotive qualification, making it unsuitable for applications requiring automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805523KFKEA be used as a direct replacement for CRCW0805523KFKEB?

A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications, tolerance, power rating, package, temperature coefficient, and operating temperature range. The only difference is the packaging suffix, which does not affect functional equivalence.

Q: Are the Panasonic and Stackpole alternatives suitable for automotive applications?

A: Yes. ERJ-6ENF5233V and RMCF0805FT523K both carry AEC-Q200 automotive qualification and meet all electrical and environmental specifications required for automotive-grade designs.

Q: Does the height difference between substitute parts affect PCB assembly?

A: No. The height variations (0.50mm, 0.65mm, 0.70mm) are within standard 0805 package tolerances and do not impact solder reflow, component placement, or clearance for typical PCB designs. Assembly equipment accommodates these variations as standard practice.

Q: Why is MCR10ERTF5233 listed if it is discontinued?

A: MCR10ERTF5233 is included for reference purposes only. It is discontinued at DiGi Electronics and lacks AEC-Q200 certification. Use only if existing inventory is available and automotive qualification is not required for the application.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel packaging is supplied in smaller quantities on cut tape segments. Both formats are compatible with standard SMD assembly processes; selection depends on production volume and inventory management requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts (CRCW0805523KFKEA, ERJ-6ENF5233V, RMCF0805FT523K) are ROHS3 compliant. MCR10ERTF5233 is also ROHS3 compliant but is discontinued.
