CRCW08052M10FKEBC Equivalent & Substitute Parts

Part Overview

The CRCW08052M10FKEBC is a 2.1 MOhm ±1% 1/8W chip resistor manufactured by Vishay Dale in 0805 (2012 Metric) package format with thick film composition. This component is currently active in production and available in tape & reel packaging. Substitute parts are necessary when the primary manufacturer part becomes unavailable, when alternative sourcing reduces lead times, or when supply chain optimization requires qualified alternatives meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08052M10FKEBC is determined by strict equivalence across the following parameters: resistance value (2.1 MOhms), tolerance (±1%), power rating (0.125W), package format (0805), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). All substitute parts must maintain identical electrical performance characteristics and physical dimensions to ensure direct replacement without circuit redesign or board layout modification. RoHS3 compliance and MSL rating 1 are required for environmental and handling compatibility.

The MCR10ERTF2104 manufactured by Rohm Semiconductor meets all substitution criteria as a direct electrical and mechanical equivalent, despite its discontinued status at DiGi Electronics.

Parameter Comparison

Engineering Selection Recommendations

The CRCW08052M10FKEBC remains the primary selection due to active product status and current availability. The MCR10ERTF2104 qualifies as a direct substitute based on complete electrical and mechanical parameter equivalence, including identical resistance, tolerance, power rating, package dimensions, and environmental compliance certifications. The marginal height difference (0.026" versus 0.024" seated height) remains within standard PCB assembly tolerances for 0805 components and does not affect circuit performance or board-level compatibility. Selection between these parts should be based on supply chain availability, lead time requirements, and cost considerations, as both components satisfy identical functional and compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTF2104 be used as a direct replacement for CRCW08052M10FKEBC on existing PCBs?

A: Yes. Both components share identical electrical specifications (2.1 MOhms ±1%, 0.125W), package format (0805), and operating characteristics. The seated height difference of 0.002" (0.05mm) is within standard PCB assembly tolerances and does not affect board-level compatibility or circuit function.

Q: What is the significance of the discontinued status for MCR10ERTF2104?

A: Discontinued status at DiGi Electronics indicates the part is no longer actively stocked by that distributor. However, this does not affect the component's electrical performance or qualification as a substitute. Availability through alternative distributors should be verified for specific procurement needs.

Q: Are there any handling or storage differences between these two parts?

A: No. Both components share identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating equivalent handling, storage, and reflow requirements. Standard ESD precautions and dry storage conditions apply to both parts.

Q: Does the packaging format difference (Tape & Reel versus Cut Tape & Digi-Reel) affect substitution eligibility?

A: No. Packaging format differences relate to supply chain logistics and handling only. The electrical and mechanical specifications of the component itself remain identical regardless of packaging format. Board-level performance is unaffected by the packaging method used during procurement.
