Substitute Part Grouping Explanation

Substitute parts for the CRCW04023K40FKEE are qualified based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Resistance value: 3.4 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.063W, 1/16W (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

All identified substitutes meet these criteria across different manufacturers, enabling direct replacement without circuit redesign or performance degradation.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CRCW04023K40FKEE, CRCW04023K40FKED, and RMCF0402FT3K40—are actively produced and carry identical electrical and mechanical specifications. Selection among these substitutes may be based on:

• Inventory availability: CRCW04023K40FKED (29,784 pcs) and RMCF0402FT3K40 (55,208 pcs) offer higher stock levels compared to CRCW04023K40FKEE (958 pcs)
• Manufacturer preference: Both Vishay Dale and Stackpole Electronics are established suppliers with AEC-Q200 qualified products
• Supply chain strategy: Cross-manufacturer qualification reduces single-source dependency
• Compliance requirements: All parts meet ROHS3 and REACH standards, suitable for regulated applications

Frequently Asked Questions (FAQ)

Q: Can CRCW04023K40FKED be used as a direct replacement for CRCW04023K40FKEE?

A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications (3.4 kOhms ±1%, 0.063W, ±100ppm/°C), package (0402), and automotive qualification (AEC-Q200). The difference lies in packaging designation; both are suitable for direct substitution.

Q: Is RMCF0402FT3K40 from Stackpole Electronics compatible with the original Vishay Dale part?

A: Yes. The RMCF0402FT3K40 matches all critical parameters: resistance, tolerance, power rating, package dimensions, temperature coefficient, operating range, and AEC-Q200 qualification. Cross-manufacturer substitution is valid for this application.

Q: What determines if a part can substitute for CRCW04023K40FKEE?

A: Substitution requires exact matching of: resistance value (3.4 kOhms), tolerance (±1%), power rating (0.063W), package (0402), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200).

Q: Are there any differences in moisture sensitivity or RoHS compliance among these parts?

A: No. All three parts carry MSL 1 (Unlimited) moisture sensitivity rating and ROHS3 compliance, ensuring equivalent handling and environmental performance.

Q: Can these parts be used interchangeably in high-reliability automotive applications?

A: Yes. All three parts hold AEC-Q200 automotive qualification, meeting reliability and quality standards for automotive-grade applications across the specified operating temperature range.
