Substitute Part Grouping Explanation

Substitution of the RG2012N-472-W-T1 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (4.7 kOhms), tolerance (±0.05%), power rating (0.125W), and temperature coefficient (±10ppm/°C) must be identical.

Mechanical Compatibility: Package format (0805 / 2012 Metric) and number of terminations (2) must match to ensure PCB footprint compatibility.

Automotive Compliance: AEC-Q200 qualification is required for automotive applications.

Environmental & Regulatory Compliance: RoHS3 compliance, Moisture Sensitivity Level 1, and REACH Unaffected status must be maintained.

Composition: Thin film construction is specified for precision and stability characteristics.

The ERA-6ARW472V from Panasonic Electronic Components meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The ERA-6ARW472V from Panasonic Electronic Components is a direct electrical and mechanical equivalent to the RG2012N-472-W-T1. Both components maintain identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. Both are AEC-Q200 qualified for automotive applications and comply with RoHS3 and REACH requirements.

The maximum seated height difference (0.50mm for Susumu versus 0.60mm for Panasonic) is within typical PCB assembly tolerances for 0805 package components and does not affect functional performance or board-level compatibility.

Both parts are Active products with established supply chains. Selection between these components may be based on availability, lead time, or procurement requirements, as electrical and mechanical performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the ERA-6ARW472V replace the RG2012N-472-W-T1 in automotive applications?

A: Yes. Both components are AEC-Q200 qualified and maintain identical electrical specifications (4.7 kOhms ±0.05%, 0.125W, ±10ppm/°C). The operating temperature range (-55°C to 155°C) and package format (0805) are identical, ensuring functional equivalence in automotive circuits.

Q: Are there differences in physical dimensions between these parts?

A: The length and width dimensions are identical (0.079" L x 0.049" W / 2.00mm x 1.25mm). The maximum seated height differs slightly: RG2012N-472-W-T1 is 0.020" (0.50mm) while ERA-6ARW472V is 0.024" (0.60mm). This 0.004" (0.10mm) difference is within standard PCB assembly tolerances for 0805 components and does not affect board-level compatibility.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the RG2012N-472-W-T1 and ERA-6ARW472V are ROHS3 compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited) ratings. Both are classified under ECCN EAR99 and HTSUS 8533.21.0030.

Q: What is the tolerance specification, and why is it important?

A: Both parts feature ±0.05% tolerance, which is a precision specification for thin film resistors. This tight tolerance is critical for applications requiring accurate voltage dividers, reference circuits, or measurement instrumentation where resistor accuracy directly affects circuit performance.

Q: Are these parts suitable for high-temperature automotive environments?

A: Yes. Both components operate across -55°C to 155°C, which covers automotive temperature extremes. The ±10ppm/°C temperature coefficient ensures stable resistance values across this range, meeting automotive reliability requirements.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive electronics council qualification standard for passive components. It certifies that the component meets automotive industry reliability, quality, and performance standards for use in vehicle applications.
