CRCW08052M05FKEAC Equivalent & Substitute Parts

Part Overview

The CRCW08052M05FKEAC is a 2.05 MOhm ±1% thick film chip resistor in 0805 (2012 Metric) package format, rated for 0.125W (1/8W) power dissipation. Manufactured by Vishay Dale, this component is currently active in production and widely available. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits component sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08052M05FKEAC is determined by strict equivalence across the following parameters:

• Resistance value: 2.05 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package format: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The MCR10ERTF2054 manufactured by Rohm Semiconductor meets all these criteria and qualifies as a direct electrical and mechanical substitute. Physical dimensions remain within acceptable tolerances for PCB assembly compatibility.

Engineering Selection Recommendations

The CRCW08052M05FKEAC remains the preferred primary selection due to its active product status and current availability. The MCR10ERTF2054 qualifies as an electrical and mechanical equivalent but carries discontinued status at major distributors, limiting its practical utility for new designs or production replenishment.

Both parts satisfy ROHS3 compliance and MSL 1 requirements, ensuring compatibility with standard PCB assembly processes and storage conditions. The maximum seated height difference of 0.002" (0.05mm) between the two parts falls within typical PCB design tolerances and does not present assembly or functional concerns.

Selection between these parts should prioritize supply chain availability and lead time requirements. The CRCW08052M05FKEAC is recommended for ongoing production and new designs. The MCR10ERTF2054 may be considered only when the primary part is unavailable and existing inventory of the substitute part is confirmed.

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTF2054 be used as a direct replacement for CRCW08052M05FKEAC in production?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 2.05 MOhms ±1%, 0.125W power rating, 0805 package, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the significance of the 0.002" height difference between these parts?

A: The seated height difference (0.024" vs 0.026") is within standard PCB assembly tolerances and does not affect component placement, solder joint formation, or circuit performance.

Q: Why is MCR10ERTF2054 listed as discontinued?

A: Discontinued status indicates the part is no longer in active production at major distributors. Existing inventory may remain available through secondary channels, but long-term availability cannot be assured.

Q: Are there packaging differences between these parts?

A: Yes. CRCW08052M05FKEAC is supplied in Tape & Reel (TR) format, while MCR10ERTF2054 is supplied in Cut Tape (CT) & Digi-Reel® format. Both formats are compatible with standard pick-and-place assembly equipment.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Both have MSL 1 (Unlimited) moisture sensitivity rating.
