Substitute Part Grouping Explanation

Substitution for CRCW08052K21FKEB is determined by strict equivalence across the following parameters: resistance value (2.21 kOhms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All substitute parts listed maintain these specifications without deviation. Packaging format (Tape & Reel or Cut Tape) does not affect electrical or mechanical compatibility. Compliance certifications (AEC-Q200, RoHS3, REACH) are preserved across all direct substitutes. Parts are grouped by manufacturer and product status to facilitate supply chain decisions.

Engineering Selection Recommendations

For direct replacement of CRCW08052K21FKEB, CRCW08052K21FKEA and CRCW08052K21FKEC from Vishay Dale are primary candidates, maintaining identical AEC-Q200 automotive certification and ROHS3 compliance. CRCW08052K21FKEA offers the highest inventory availability (44,104 units) among Vishay options.

ERJ-6ENF2211V from Panasonic Electronic Components provides an alternative from a different manufacturer while maintaining full AEC-Q200 and ROHS3 compliance, with substantial inventory (105,761 units).

RMCF0805FT2K21 from Stackpole Electronics Inc is available in high volume (130,326 units) and meets all electrical and compliance requirements including AEC-Q200 and ROHS3.

KTR10EZPF2211 from Rohm Semiconductor is designated as an upgrade option, offering identical electrical specifications with additional high-voltage capability features while maintaining AEC-Q200 and ROHS3 compliance.

CRCW08052K21FKTC maintains electrical equivalence but is RoHS non-compliant and REACH-affected, limiting suitability for new designs requiring regulatory compliance.

CRCW08052K21FKEAC and CRCW08052K21FKEBC lack AEC-Q200 automotive certification, making them unsuitable for automotive applications despite ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can CRCW08052K21FKEA directly replace CRCW08052K21FKEB in automotive applications?

A: Yes. Both parts are electrically identical (2.21 kOhms ±1%, 0.125W, 0805 package) and maintain AEC-Q200 automotive certification and ROHS3 compliance. The primary difference is product status: FKEB is discontinued while FKEA is active with higher inventory availability.

Q: What is the difference between RMCF0805FG2K21 and RMCF0805FT2K21?

A: Both are electrically and mechanically identical. The difference is packaging format: FG2K21 is supplied in Cut Tape (CT) format, while FT2K21 is supplied in Tape & Reel (TR) format. Electrical performance and compliance certifications are identical.

Q: Why is CRCW08052K21FKTC not recommended as a substitute?

A: While electrically equivalent, CRCW08052K21FKTC is RoHS non-compliant and REACH-affected. For applications requiring regulatory compliance with RoHS3 and REACH standards, this part does not meet requirements.

Q: Can I use CRCW08052K21FKEAC or CRCW08052K21FKEBC in automotive circuits?

A: No. Although these parts are electrically identical and ROHS3 compliant, they lack AEC-Q200 automotive certification. Use only AEC-Q200 rated parts for automotive applications.

Q: Is ERJ-6ENF2211V from Panasonic a suitable cross-manufacturer substitute?

A: Yes. ERJ-6ENF2211V maintains all critical electrical parameters (2.21 kOhms ±1%, 0.125W, 0805 package), AEC-Q200 certification, and ROHS3 compliance. It is a direct functional equivalent from a different manufacturer with excellent inventory availability.

Q: What does the height difference between parts mean for PCB assembly?

A: All listed parts fit the 0805 (2012 Metric) package standard. Maximum seated heights range from 0.50mm to 0.70mm. These variations are within standard PCB assembly tolerances and do not affect placement or soldering processes.

Q: Is KTR10EZPF2211 a true equivalent or an upgrade?

A: KTR10EZPF2211 is designated as an upgrade. It maintains identical electrical specifications (2.21 kOhms ±1%, 0.125W) and all compliance certifications, but adds high-voltage capability features. It functions as a direct replacement with enhanced performance characteristics.
