CRCW0805523KFKEAC Equivalent & Substitute Parts

Part Overview

The CRCW0805523KFKEAC 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 is currently active in production status with 885 pieces available in inventory as new original stock.

Substitute parts become necessary when the primary manufacturer part experiences supply constraints, extended lead times, or when design flexibility permits component sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW0805523KFKEAC 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 format: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match or wider range acceptable)

The MCR10ERTF5233 manufactured by Rohm Semiconductor meets all electrical and mechanical substitution criteria. Both components share identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Physical dimensions remain compatible within standard PCB assembly tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both the CRCW0805523KFKEAC and MCR10ERTF5233 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

The CRCW0805523KFKEAC maintains active production status with established supply availability. The MCR10ERTF5233 is discontinued at DiGi Electronics, indicating limited future procurement viability through standard distribution channels.

Selection between these components should prioritize the CRCW0805523KFKEAC for new designs and long-term production requirements due to active manufacturer status. The MCR10ERTF5233 remains electrically and mechanically equivalent for applications where existing inventory or alternative sourcing channels provide component availability.

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTF5233 be used as a direct replacement for CRCW0805523KFKEAC in PCB assembly?

A: Yes. Both components share identical electrical specifications (523 kOhms ±1%, 0.125W, ±100ppm/°C) and package dimensions (0805 / 2012 Metric). The maximum seated height difference of 0.002" (0.05mm) falls within standard PCB assembly tolerances and does not affect placement or soldering operations.

Q: Are there compliance or certification differences between these parts?

A: No. Both components carry ROHS3 compliance and REACH unaffected status. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts.

Q: What is the primary reason to consider MCR10ERTF5233 as a substitute?

A: The MCR10ERTF5233 serves as an alternative source when CRCW0805523KFKEAC supply is constrained. However, the MCR10ERTF5233 is discontinued at DiGi Electronics, limiting its practical availability for new procurement.

Q: Do these resistors require different handling or storage procedures?

A: No. Both components share identical moisture sensitivity classification (MSL 1 - Unlimited), requiring no special moisture control during storage or handling.

Q: Are there any thermal performance differences between these parts?

A: No. Both components operate across -55°C to 155°C with identical temperature coefficient specifications of ±100ppm/°C.
