Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08051M40FKEB is determined by strict equivalence across the following parameters:

• Resistance value: 1.4 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 compliance: AEC-Q200
• RoHS compliance: ROHS3
• Moisture sensitivity: MSL 1

All identified substitute parts meet these criteria. Dimensional variations within the 0805 package specification (height-seated maximum) do not affect functional compatibility or PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed are active products with full AEC-Q200 automotive compliance and ROHS3 certification. Selection between CRCW08051M40FKEB and its substitutes should be based on:

CRCW08051M40FKEA (Vishay Dale) is a direct manufacturer equivalent with identical electrical and mechanical specifications. This part maintains the same height profile (0.50mm) and represents the primary alternative within the Vishay Dale CRCW series.

ERJ-6ENF1404V (Panasonic Electronic Components) provides full electrical equivalence with AEC-Q200 compliance. The height-seated maximum of 0.70mm remains within standard 0805 package tolerances and does not impact PCB assembly compatibility.

KTR10EZPF1404 (Rohm Semiconductor) offers equivalent electrical performance with additional high-voltage capability designation. The height-seated maximum of 0.65mm is within specification tolerance. This part provides design flexibility for applications requiring enhanced voltage performance characteristics.

All parts are suitable for direct substitution in automotive applications requiring 1.4 MOhms ±1% 0.125W thick film resistors in 0805 package format.

Frequently Asked Questions (FAQ)

Q: Can CRCW08051M40FKEB be replaced with ERJ-6ENF1404V in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, share identical electrical specifications (1.4 MOhms ±1%, 0.125W, ±100ppm/°C), and are packaged in 0805 (2012 Metric) format. The 0.70mm height of ERJ-6ENF1404V is within 0805 package specification and compatible with standard PCB assembly processes.

Q: What is the difference between CRCW08051M40FKEB and CRCW08051M40FKEA?

A: Both are Vishay Dale products with identical electrical and mechanical specifications. The difference is in packaging designation (FKEB vs FKEA), which reflects different tape and reel configurations. Electrical performance and physical dimensions are equivalent.

Q: Is KTR10EZPF1404 suitable for standard automotive circuits?

A: Yes. KTR10EZPF1404 meets all electrical requirements for 1.4 MOhms ±1% 0.125W applications and carries AEC-Q200 certification. The high-voltage designation indicates additional capability beyond standard requirements and does not restrict use in standard automotive circuits.

Q: Are all substitute parts RoHS compliant?

A: Yes. CRCW08051M40FKEB, CRCW08051M40FKEA, ERJ-6ENF1404V, and KTR10EZPF1404 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All parts are mechanically compatible within 0805 package specification and electrically equivalent. Height variations (0.50mm to 0.70mm) do not affect PCB assembly, soldering, or functional performance.
