Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Resistance Value: Must be 412 Ohms
• Tolerance: Must be ±0.1%
• Package: Must be 0805 (2012 Metric)
• Composition: Must be Thin Film
• Temperature Coefficient: Must be ±25ppm/°C
• Operating Temperature Range: Must support -55°C ~ 155°C
• RoHS & Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The substitute parts listed below meet these core electrical and mechanical requirements. Power rating variations are noted where applicable, as they represent a secondary parameter that may affect suitability depending on circuit design margins.

Parameter Comparison

Engineering Selection Recommendations

RNCF0805BTE412R (Primary Reference): Stackpole Electronics Inc manufacture. AEC-Q200 automotive qualified. 0.25W power rating. Tape & Reel packaging. Recommended for applications requiring explicit automotive qualification.

ERA-6AEB4120V (Panasonic Electronic Components): Direct electrical equivalent with identical tolerance and temperature characteristics. AEC-Q200 automotive qualified. Power rating is 0.125W (1/8W), which is lower than the primary part. Suitable for applications where circuit power dissipation does not exceed 0.125W. Available in Cut Tape and Digi-Reel® packaging formats. High inventory availability (10,655 pcs).

8-2176091-1 (TE Connectivity Passive Product): Matched power rating (0.25W) and electrical specifications. ROHS3 compliant and REACH unaffected. Automotive qualification not specified in available data. Tape & Reel packaging. Suitable for non-automotive or general industrial applications where AEC-Q200 certification is not mandatory.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB4120V replace RNCF0805BTE412R in all applications?

A: ERA-6AEB4120V matches all electrical parameters (resistance, tolerance, temperature coefficient, operating range) and maintains AEC-Q200 automotive qualification. However, its power rating is 0.125W versus 0.25W for the primary part. Substitution is valid only if circuit power dissipation at this resistor does not exceed 0.125W.

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

A: Tape & Reel (TR) packaging is supplied on continuous reels suitable for automated pick-and-place assembly. Cut Tape (CT) is supplied in shorter tape segments. Digi-Reel® is Panasonic's proprietary reel format. Selection depends on assembly equipment and production volume requirements.

Q: Is 8-2176091-1 suitable for automotive applications?

A: 8-2176091-1 meets ROHS3 and REACH compliance requirements. Automotive qualification (AEC-Q200) is not specified in the available technical data. Use in automotive applications should be evaluated against specific design requirements and qualification standards.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts share identical package dimensions (0805 / 2012 Metric), footprint, and termination count (2). Physical placement on PCBs is interchangeable. Electrical performance differences are limited to power rating variations noted in the parameter comparison table.

Q: What is the significance of ±0.1% tolerance?

A: ±0.1% tolerance indicates high precision resistors suitable for applications requiring tight resistance accuracy. All three substitute parts maintain this specification, ensuring equivalent performance in precision circuits.
