Substitute Part Grouping Explanation

Substitution for the CRCW08052M49FKEB is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.49 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The substitute part CRCW08052M49FKEA matches all electrical and mechanical specifications, differing only in packaging designation (FKEA vs FKEB suffix). Both parts are manufactured by Vishay Dale within the CRCW series and maintain identical performance characteristics across all rated parameters.

Parameter Comparison

Engineering Selection Recommendations

Both CRCW08052M49FKEB and CRCW08052M49FKEA are active production parts from Vishay Dale with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on availability and supply chain requirements. The CRCW08052M49FKEA offers higher inventory availability (14455 pieces versus 1109 pieces), making it suitable for high-volume production runs or long-term supply assurance. Both parts are electrically and mechanically identical and are suitable for direct substitution in automotive applications requiring 2.49 MOhms ±1% 0.125W resistors in 0805 package format.

Frequently Asked Questions (FAQ)

Q: Can CRCW08052M49FKEA be used as a direct replacement for CRCW08052M49FKEB?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical resistance, tolerance, power rating, package dimensions, temperature coefficient, and operating temperature range. The suffix difference (FKEA vs FKEB) does not affect functional performance or compatibility.

Q: Are there any differences in automotive qualification between these parts?

A: No. Both parts carry AEC-Q200 qualification and are suitable for automotive applications requiring this standard.

Q: Do these parts have the same RoHS and REACH compliance status?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of the packaging designation suffix?

A: The suffix (FKEA vs FKEB) indicates packaging or manufacturing batch designation but does not alter electrical specifications, performance characteristics, or physical dimensions. Both are supplied in Tape & Reel (TR) format.

Q: Can these resistors be used interchangeably in PCB assembly?

A: Yes. Identical 0805 (2012 Metric) package dimensions and termination specifications ensure mechanical and electrical interchangeability in PCB layouts and assembly processes.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.
