Substitute Part Grouping Explanation

Substitution eligibility for the CRCW04029R76FNED is determined by strict equivalence across the following critical parameters:

• Resistance value: 9.76 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.063W minimum (1/16W)
• Package: 0402 (1005 Metric) form factor
• Composition: Thick film construction
• Automotive qualification: AEC-Q200 certification
• Operating temperature range: -55°C to 155°C minimum
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 or better

The CRCW04029R76FKED qualifies as a direct substitute based on full alignment with these parameters. Both parts are manufactured by Vishay Dale within the CRCW series and share identical electrical specifications, package dimensions, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both CRCW04029R76FNED and CRCW04029R76FKED are qualified for direct substitution in automotive and industrial applications requiring AEC-Q200 compliance. Selection between these parts should be based on:

Inventory availability and lead time requirements. The CRCW04029R76FKED maintains significantly higher stock levels (15,690 pcs vs. 745 pcs), making it preferable for high-volume production or time-sensitive procurement.

Temperature coefficient performance. The CRCW04029R76FKED offers superior temperature stability at ±100ppm/°C compared to ±200ppm/°C for the CRCW04029R76FNED. This difference is relevant for precision analog circuits operating across the full -55°C to 155°C range.

Both parts maintain identical mechanical compatibility, electrical performance within tolerance, and regulatory compliance. No design modifications are required when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Can CRCW04029R76FKED be used as a direct replacement for CRCW04029R76FNED?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, package dimensions, and AEC-Q200 automotive qualification. The CRCW04029R76FKED features improved temperature coefficient performance.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use the 0402 (1005 Metric) package with identical dimensions: 0.039" L × 0.020" W (1.00mm × 0.50mm) and maximum seated height of 0.016" (0.40mm). PCB footprints are interchangeable.

Q: What is the significance of the temperature coefficient difference?

A: The CRCW04029R76FKED operates at ±100ppm/°C versus ±200ppm/°C for the CRCW04029R76FNED. For a 9.76 Ohm resistor across a 210°C temperature swing (-55°C to 155°C), this represents a maximum resistance change of approximately 0.21 Ohms (FKED) versus 0.41 Ohms (FNED). Selection depends on circuit tolerance requirements.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both CRCW04029R76FNED and CRCW04029R76FKED carry AEC-Q200 certification and are ROHS3 compliant with MSL 1 moisture sensitivity rating.

Q: What packaging format is used for these parts?

A: Both parts are supplied in Tape & Reel (TR) format suitable for automated assembly processes.
