CRCW0805523KFKEBC Equivalent & Substitute Parts

Part Overview

The CRCW0805523KFKEBC is a 523 kOhms ±1% thick film chip resistor manufactured by Vishay Dale in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with 989 units currently in stock. Substitute parts become necessary when primary inventory is depleted, when supply chain constraints affect availability, or when design requirements permit equivalent electrical and mechanical specifications from alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW0805523KFKEBC is determined by strict equivalence across the following parameters: resistance value (523 kOhms), tolerance (±1%), power rating (0.125W), package format (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3, REACH Unaffected). The MCR10ERTF5233 manufactured by Rohm Semiconductor meets all these criteria and qualifies as a direct electrical and mechanical equivalent. Dimensional compatibility is confirmed through matching package specifications and maximum seated height within acceptable tolerances for standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The MCR10ERTF5233 is a qualified substitute for the CRCW0805523KFKEBC based on complete electrical and mechanical equivalence. Both components satisfy ROHS3 compliance and REACH regulatory requirements. The MCR10ERTF5233 carries Discontinued at DiGi Electronics status, indicating limited future availability through standard distribution channels. Selection between these parts should prioritize current inventory status and supply chain reliability. The maximum seated height difference of 0.002" (0.05mm) between the two components remains within standard PCB assembly tolerances and does not affect form-fit-function compatibility in typical applications.

Frequently Asked Questions (FAQ)

Q: Can the MCR10ERTF5233 be used as a direct replacement for the CRCW0805523KFKEBC?

A: Yes. Both components share identical electrical specifications (523 kOhms ±1%, 0.125W, ±100ppm/°C) and mechanical package format (0805). The maximum seated height difference of 0.002" falls within standard assembly tolerances.

Q: Are there any compliance differences between these parts?

A: No. Both components are ROHS3 Compliant, REACH Unaffected, and carry identical Moisture Sensitivity Level (MSL 1). Regulatory compliance is equivalent.

Q: What is the significance of the MCR10ERTF5233 being Discontinued at DiGi Electronics?

A: Discontinued status indicates the part is no longer actively distributed through this channel. Existing inventory may be available through alternative suppliers, but future procurement should prioritize the CRCW0805523KFKEBC or identify additional qualified substitutes for long-term supply assurance.

Q: Does the 0.002" height difference affect PCB assembly?

A: No. The height variance (0.024" vs 0.026" maximum seated height) is negligible for standard surface mount assembly processes and does not impact reflow soldering, component placement, or clearance requirements in typical circuit board designs.

Q: Are the package dimensions identical?

A: Yes. Both components conform to the 0805 (2012 Metric) package specification with matching length (0.079") and width (0.049") dimensions.
