CRCW08054K87FKTA Equivalent & Substitute Parts

Part Overview

The CRCW08054K87FKTA is a 4.87 kOhms ±1% 0.125W (1/8W) chip resistor in 0805 (2012 Metric) package manufactured by Vishay Dale. This thick film resistor is rated for automotive applications under AEC-Q200 standard with an operating temperature range of -55°C to 155°C. The part is currently active in production. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when design requirements necessitate alternative specifications such as increased power rating or enhanced pulse withstanding capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CRCW08054K87FKTA are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalents (Identical Specifications): Parts that match all critical parameters including resistance value (4.87 kOhms), tolerance (±1%), power rating (0.125W), package (0805), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). These parts are pin-compatible and functionally interchangeable without circuit modification.

Upgrade Equivalents (Enhanced Power Rating): Parts that maintain the same resistance, tolerance, package, and temperature specifications but feature increased power rating (0.5W / 1/2W) and pulse withstanding capability. These parts are physically compatible and electrically superior for applications requiring higher transient energy dissipation.

The substitution logic is determined by the following parameters: resistance value, tolerance, package type, operating temperature range, and composition. All substitute parts listed maintain these core specifications. Differences in power rating, RoHS compliance status, and manufacturer-specific features are noted but do not prevent substitution when electrical requirements are met.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection (CRCW08054K87FKEA, ERJ-6ENF4871V, RC0805FR-074K87L, RMCF0805FT4K87): These parts provide identical electrical and mechanical specifications to the CRCW08054K87FKTA. All direct equivalents are ROHS3 compliant and carry active product status. Selection among direct equivalents is based on manufacturer preference, supply chain availability, and compliance requirements. The CRCW08054K87FKEA maintains the same Vishay Dale manufacturer lineage. The ERJ-6ENF4871V from Panasonic and RMCF0805FT4K87 from Stackpole Electronics both carry AEC-Q200 automotive certification. The RC0805FR-074K87L from YAGEO features moisture-resistant construction.

Upgrade Equivalent Selection (CRCW08054K87FKEAHP, RCS08054K87FKEA): These parts are suitable when circuit design requires enhanced pulse withstanding capability or higher transient energy dissipation. Both upgrade equivalents maintain AEC-Q200 automotive certification and ROHS3 compliance. The CRCW08054K87FKEAHP is part of the CRCW-HP series with 0.5W power rating. The RCS08054K87FKEA from the RCS e3 series also provides 0.5W power rating with pulse withstanding features. Upgrade equivalents are physically compatible with the original 0805 package footprint and do not require PCB layout modifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW08054K87FKEAHP and RCS08054K87FKEA be used as direct replacements for CRCW08054K87FKTA?

A: Yes, these upgrade equivalents are physically and electrically compatible. They maintain the same 4.87 kOhms resistance, ±1% tolerance, 0805 package, and operating temperature range. The increased power rating (0.5W versus 0.125W) and pulse withstanding capability provide enhanced performance without requiring circuit modifications.

Q: What is the difference between direct equivalents and upgrade equivalents?

A: Direct equivalents (CRCW08054K87FKEA, ERJ-6ENF4871V, RC0805FR-074K87L, RMCF0805FT4K87) match all specifications of the CRCW08054K87FKTA including 0.125W power rating. Upgrade equivalents (CRCW08054K87FKEAHP, RCS08054K87FKEA) feature 0.5W power rating and pulse withstanding capability while maintaining all other electrical and mechanical parameters.

Q: Are all substitute parts AEC-Q200 automotive rated?

A: Most substitute parts carry AEC-Q200 certification. The RC0805FR-074K87L from YAGEO is rated for moisture resistance rather than automotive AEC-Q200. All parts maintain the same operating temperature range (-55°C to 155°C) and composition specifications.

Q: What is the RoHS compliance status of substitute parts?

A: All listed substitute parts are ROHS3 compliant. The original CRCW08054K87FKTA is RoHS non-compliant. If RoHS compliance is required for new designs, any of the substitute parts provide compliant alternatives.

Q: Are there physical footprint differences between substitute parts?

A: All substitute parts use the 0805 (2012 Metric) package with identical land pattern dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Height variations are minimal (0.020" to 0.028" seated height) and do not affect PCB assembly compatibility.

Q: Can substitute parts from different manufacturers be mixed in the same design?

A: Yes. All substitute parts meet the same electrical specifications (4.87 kOhms ±1%, ±100ppm/°C, -55°C to 155°C operating range) and package standard (0805). Mixing manufacturers is acceptable from an electrical and mechanical standpoint, though design documentation should specify the approved part list.
