Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS0805FT2K74 is determined by strict equivalence across the following parameters:

• Resistance Value: 2.74 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 0805 (2012 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)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in secondary characteristics such as automotive qualification (AEC-Q200), pulse withstanding capability, or specific feature sets (anti-sulfur vs. moisture resistant) do not disqualify substitution but indicate application-specific enhancements.

Parameter Comparison

Engineering Selection Recommendations

RMCF0805FT2K74 (Stackpole Electronics Inc): Direct manufacturer upgrade with automotive AEC-Q200 qualification and ROHS3 compliance. Recommended for applications requiring automotive-grade reliability with same form factor and power rating as the original part.

CRCW08052K74FKEA (Vishay Dale): Automotive AEC-Q200 qualified alternative with ROHS3 compliance. Electrically and mechanically equivalent to the main part with established supply availability.

CRCW08052K74FKEAHP (Vishay Dale): Automotive AEC-Q200 qualified alternative with pulse withstanding capability and 0.5W power rating. Suitable for applications requiring enhanced transient protection while maintaining 0805 package compatibility. ROHS3 compliant.

CRCW08052K74FKTA (Vishay Dale): Automotive AEC-Q200 qualified alternative with equivalent electrical specifications. Note: RoHS non-compliant status may restrict use in regulated applications.

ERJ-6ENF2741V (Panasonic Electronic Components): Automotive AEC-Q200 qualified alternative with ROHS3 compliance. Established supply base with high inventory availability.

RC0805FR-072K74L (YAGEO): Moisture resistant thick film construction with ROHS3 compliance. Suitable for general industrial applications with equivalent electrical performance to the main part.

Frequently Asked Questions (FAQ)

Q: Can CRCW08052K74FKEAHP be used as a direct replacement for RMCS0805FT2K74?

A: Yes, electrically and mechanically. The CRCW08052K74FKEAHP maintains identical resistance, tolerance, temperature coefficient, and operating range. The 0.5W power rating is a superset of the 0.125W requirement, making it compatible for any circuit designed for the original part. The 0805 package dimensions are identical.

Q: What is the difference between anti-sulfur and moisture resistant features?

A: Anti-sulfur construction (RMCS0805FT2K74) protects against sulfur-containing atmospheric corrosion. Moisture resistant construction (RC0805FR-072K74L) provides protection against humidity ingress. Both are thick film resistors with equivalent electrical performance. Feature selection depends on environmental exposure conditions.

Q: Are all substitute parts automotive qualified?

A: No. The RMCS0805FT2K74 (original) and RC0805FR-072K74L lack automotive AEC-Q200 qualification. RMCF0805FT2K74, CRCW08052K74FKEA, CRCW08052K74FKEAHP, CRCW08052K74FKTA, and ERJ-6ENF2741V carry AEC-Q200 qualification. Select automotive-qualified parts for automotive applications.

Q: Does RoHS compliance affect substitution eligibility?

A: RoHS compliance is a regulatory requirement, not an electrical parameter. CRCW08052K74FKTA is RoHS non-compliant and may be restricted in regulated markets. All other substitutes are ROHS3 compliant. Verify regulatory requirements for your application before selection.

Q: Are the physical dimensions identical across all substitute parts?

A: All parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Height varies slightly: RMCS0805FT2K74 and RC0805FR-072K74L are 0.024" (0.60mm), while RMCF0805FT2K74, CRCW08052K74FKEA, CRCW08052K74FKEAHP, and CRCW08052K74FKTA are 0.020" (0.50mm), and ERJ-6ENF2741V is 0.028" (0.70mm). These variations are within standard PCB assembly tolerances.

Q: Which substitute has the highest inventory availability?

A: RC0805FR-072K74L (YAGEO) has the highest inventory at 157,306 pieces, followed by ERJ-6ENF2741V (Panasonic) at 86,311 pieces. RMCF0805FT2K74 (Stackpole) has 47,155 pieces available.
