Substitute Part Grouping Explanation

Substitution of the RG2012P-183-W-T5 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 18 kOhms (exact match required)
• Tolerance: ±0.05% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)

Mechanical Specifications:

• Package format: 0805 (2012 Metric) (exact match required)
• Number of terminations: 2 (exact match required)

Environmental & Compliance:

• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

The ERA-6ARW183V manufactured by Panasonic Electronic Components meets all substitution criteria. Both components are thin film resistors with identical electrical performance, package dimensions, and compliance certifications. Variations in temperature coefficient (±25ppm/°C vs. ±10ppm/°C) and maximum seated height (0.020" vs. 0.024") do not preclude substitution within standard PCB design tolerances for this resistor category.

Parameter Comparison

Engineering Selection Recommendations

Both the RG2012P-183-W-T5 and ERA-6ARW183V are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts is based on availability, supply chain considerations, and design-specific requirements.

The RG2012P-183-W-T5 features anti-sulfur coating, which provides enhanced corrosion resistance in harsh environments. The ERA-6ARW183V offers a lower temperature coefficient (±10ppm/°C versus ±25ppm/°C), resulting in improved frequency stability and reduced drift over the operating temperature range. The ERA-6ARW183V has a maximum seated height of 0.024" compared to 0.020" for the RG2012P-183-W-T5; this 0.004" difference is within standard PCB design clearance tolerances for 0805 package components.

Both components are suitable for direct substitution in automotive and industrial applications requiring precision thin film resistors with tight tolerance specifications and extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can the ERA-6ARW183V replace the RG2012P-183-W-T5 in existing designs?

A: Yes. Both components share identical electrical specifications (18 kOhms ±0.05%, 0.125W), package format (0805), operating temperature range (-55°C ~ 155°C), and automotive certifications (AEC-Q200). The components are mechanically and electrically interchangeable.

Q: What is the significance of the temperature coefficient difference?

A: The ERA-6ARW183V has a temperature coefficient of ±10ppm/°C compared to ±25ppm/°C for the RG2012P-183-W-T5. This means the Panasonic component exhibits lower resistance drift across temperature variations. For applications requiring maximum frequency stability or precision analog circuits, the lower temperature coefficient of the ERA-6ARW183V provides superior performance.

Q: Does the height difference affect PCB layout?

A: The ERA-6ARW183V has a maximum seated height of 0.024" (0.60mm) versus 0.020" (0.50mm) for the RG2012P-183-W-T5. This 0.004" difference is negligible for standard PCB designs and does not impact component placement, solder reflow profiles, or conformal coating processes.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the RG2012P-183-W-T5 and ERA-6ARW183V carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and performance standards. Both are suitable for use in automotive electronic control modules, sensor interfaces, and power management circuits.

Q: What is the anti-sulfur coating on the RG2012P-183-W-T5?

A: The anti-sulfur coating on the Susumu RG2012P-183-W-T5 provides enhanced resistance to sulfur-containing atmospheric contaminants and corrosive environments. This feature is beneficial in industrial and harsh environment applications. The ERA-6ARW183V does not specify anti-sulfur coating; selection should be based on environmental exposure requirements.

Q: Are both components RoHS compliant?

A: Yes. Both the RG2012P-183-W-T5 and ERA-6ARW183V are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in the European Union and other regulated markets.

Q: What is the moisture sensitivity level, and why does it matter?

A: Both components have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture baking requirements. This simplifies inventory management and reduces handling constraints compared to higher MSL ratings.
