Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT0805FRE074K7L is determined by the following critical parameters:

• Resistance Value: Must be 4.7 kOhms
• Package / Case: Must be 0805 (2012 Metric)
• Power Rating: Must be 0.125W (1/8W)
• Composition: Must be Thin Film
• Temperature Coefficient: Must be ±50ppm/°C
• Operating Temperature Range: Must be -55°C ~ 155°C
• RoHS Status: Must be ROHS3 Compliant
• Moisture Sensitivity Level: Must be 1 (Unlimited)

The substitute parts listed below meet all mandatory electrical and mechanical parameters. Variations in tolerance specification (±0.1%, ±0.5%, ±1%) and packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) are permitted substitutions based on circuit requirements and procurement logistics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components from YAGEO with ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

RT0805BRE074K7L provides tighter tolerance specification (±0.1%) compared to the original AT0805FRE074K7L (±1%), suitable for applications requiring higher precision resistor values. This part maintains Tape & Reel packaging format.

RT0805DRE074K7L offers intermediate tolerance (±0.5%) with Cut Tape & Digi-Reel packaging, providing flexibility for mixed procurement strategies or lower-volume assembly requirements.

RT0805FRE074K7L matches the original tolerance specification (±1%) and is available in Cut Tape & Digi-Reel format, offering the highest inventory availability (42,031 units) for high-volume production scenarios.

Selection between substitute parts should be based on tolerance requirements for the specific circuit function and packaging format compatibility with assembly equipment and procurement workflows.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRE074K7L replace AT0805FRE074K7L in all applications?

A: Yes, provided the circuit design permits the tighter ±0.1% tolerance. The RT0805BRE074K7L meets all electrical and mechanical parameters of the original part. Applications requiring only ±1% tolerance will function identically with either part.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) packaging is supplied on continuous carrier tape in full reel quantities, optimized for high-speed automated assembly. Cut Tape (CT) & Digi-Reel packaging provides flexibility for mixed-volume orders and lower-quantity requirements. Both formats contain identical components.

Q: Are all substitute parts automotive-qualified?

A: The AT0805FRE074K7L carries AEC-Q200 automotive qualification. The substitute parts (RT series) do not list AEC-Q200 qualification in the provided specifications. For automotive applications requiring AEC-Q200 compliance, the original AT0805FRE074K7L is the specified choice.

Q: Can tolerance be mixed within a single assembly?

A: Yes. Circuits can accommodate multiple tolerance grades simultaneously. However, for matched resistor networks or precision analog circuits, consistent tolerance specification across all resistors in the functional block is recommended based on circuit design requirements.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Unlimited) indicates these components have unlimited shelf life and require no special moisture control during storage or handling, simplifying inventory management and reducing component preparation time before assembly.
