Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08051K27FKEC is determined by strict equivalence across the following parameters: resistance value (1.27 kOhms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99). All identified substitute parts meet these core electrical and mechanical requirements. Substitute parts are categorized as direct equivalents, upgrades, or manufacturer-recommended alternatives based on feature additions or packaging variations that do not compromise primary functionality.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical equivalence to the CRCW08051K27FKEC across resistance, tolerance, power rating, and temperature specifications. Selection among these parts should be based on the following factors:

CRCW08051K27FKEA (Vishay Dale) is a direct equivalent with identical height specification and AEC-Q200 automotive rating. This part offers the highest inventory availability at 27,118 units.

ERJ-6ENF1271V (Panasonic Electronic Components) meets all electrical requirements with AEC-Q200 compliance. The seated height is 0.70mm, which is 0.20mm higher than the primary part. This dimension difference must be evaluated against PCB layout constraints.

RMCF0805FT1K27 (Stackpole Electronics Inc) provides direct electrical equivalence with AEC-Q200 rating and a seated height of 0.65mm. Inventory availability is 18,168 units.

KTR10EZPF1271 (Rohm Semiconductor) is classified as an upgrade option due to the addition of high voltage capability while maintaining all base electrical specifications and AEC-Q200 compliance. Seated height is 0.65mm with 10,451 units available.

CR0805-FX-1271ELF (Bourns Inc.) is the manufacturer-recommended alternative, featuring moisture-resistant construction. This part does not carry explicit AEC-Q200 designation but maintains all core electrical parameters. Seated height is 0.60mm with 25,712 units in stock.

All parts are ROHS3 compliant, REACH unaffected, and classified under EAR99 export control.

Frequently Asked Questions (FAQ)

Q: Can CRCW08051K27FKEA be used as a direct replacement for CRCW08051K27FKEC?

A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications (1.27 kΩ, ±1%, 0.125W), package type (0805), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and AEC-Q200 automotive rating. The seated height is identical at 0.50mm.

Q: What is the significance of the height differences among substitute parts?

A: Seated height variations (0.50mm to 0.70mm) may impact PCB assembly clearance, solder joint formation, and component placement in densely populated boards. Verify that the substitute part's height specification is compatible with your PCB design and assembly process before implementation.

Q: Are all substitute parts suitable for automotive applications?

A: CRCW08051K27FKEC, CRCW08051K27FKEA, ERJ-6ENF1271V, RMCF0805FT1K27, and KTR10EZPF1271 all carry AEC-Q200 automotive qualification. CR0805-FX-1271ELF does not explicitly list AEC-Q200 rating; confirm suitability for your specific automotive application requirements.

Q: What does the high voltage feature on KTR10EZPF1271 provide?

A: The KTR10EZPF1271 includes high voltage capability as an additional feature. All other electrical parameters remain equivalent to the primary part. This upgrade option is suitable for applications requiring enhanced voltage performance without changing the base 1.27 kΩ, ±1%, 0.125W specification.

Q: Are all parts RoHS compliant?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing.

Q: What is the difference between the Vishay Dale CRCW series parts?

A: CRCW08051K27FKEC and CRCW08051K27FKEA are both Vishay Dale CRCW series resistors with identical electrical and mechanical specifications. The difference lies in packaging or internal manufacturing designation (indicated by the suffix). Both are functionally equivalent for circuit design purposes.
