Key Parameters

Substitute Part Grouping Explanation

Substitution of the CRCW08054R42FNTA is determined by strict equivalence across the following critical parameters:

• Resistance value: 4.42 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W, 1/8W (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Number of terminations: 2 (exact match required)

The RC0805FR-074R42L from YAGEO meets all these critical parameters and qualifies as a direct substitute. Both parts share identical electrical specifications and mechanical dimensions within the 0805 package standard.

Parameter Comparison

Engineering Selection Recommendations

Both the CRCW08054R42FNTA and RC0805FR-074R42L are active production parts with identical electrical and mechanical specifications. The primary differentiation lies in compliance certifications and physical height tolerance.

The CRCW08054R42FNTA carries AEC-Q200 automotive qualification and is RoHS non-compliant. The RC0805FR-074R42L is ROHS3 compliant and features moisture-resistant construction. The seated height difference of 0.004" (0.10mm) between the two parts is within typical PCB assembly tolerances for 0805 components.

Selection between these parts should be based on specific application requirements: choose CRCW08054R42FNTA for automotive applications requiring AEC-Q200 certification, or RC0805FR-074R42L for applications requiring RoHS3 compliance and moisture resistance.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-074R42L replace CRCW08054R42FNTA in automotive applications?

A: Both parts share identical electrical specifications (4.42 Ohms ±1%, 0.125W, ±200ppm/°C, -55°C to 155°C). However, the CRCW08054R42FNTA carries AEC-Q200 automotive qualification while the RC0805FR-074R42L does not. Application requirements determine suitability.

Q: What is the significance of the 0.004" height difference?

A: The CRCW08054R42FNTA has a maximum seated height of 0.020" (0.50mm) while the RC0805FR-074R42L is 0.024" (0.60mm). This 0.004" (0.10mm) difference is within standard PCB assembly tolerances for 0805 components and does not affect mechanical compatibility.

Q: Are there compliance differences between these parts?

A: Yes. The CRCW08054R42FNTA is RoHS non-compliant, while the RC0805FR-074R42L is ROHS3 compliant. The RC0805FR-074R42L also features moisture-resistant construction. Application compliance requirements should guide selection.

Q: Do both parts use the same packaging format?

A: Yes. Both the CRCW08054R42FNTA and RC0805FR-074R42L are supplied in Tape & Reel (TR) packaging and are compatible with standard SMD assembly equipment.

Q: What determines if a part can substitute for CRCW08054R42FNTA?

A: Direct substitution requires exact matching of resistance value (4.42 Ohms), tolerance (±1%), power rating (0.125W), package (0805), composition (Thick Film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 155°C), and termination count (2).
