Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-222-W-T5 is determined by strict equivalence across the following parameters:

Electrical Specifications: Resistance value (2.2 kOhms), tolerance (±0.05%), and power rating (0.125W) must be identical. Thin film composition is required to maintain tolerance and temperature stability characteristics.

Mechanical Compatibility: Package format must be 0805 (2012 Metric) with matching termination count (2 terminations). Physical dimensions must accommodate the same PCB footprint.

Environmental & Compliance Requirements: Operating temperature range (-55°C ~ 155°C) and AEC-Q200 automotive qualification must be maintained. RoHS3 compliance and MSL 1 rating ensure regulatory and manufacturing process compatibility.

Packaging Format: Tape & Reel (TR) packaging maintains supply chain compatibility.

The ERA-6ARW222V from Panasonic Electronic Components qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

Both the RG2012P-222-W-T5 and ERA-6ARW222V are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts is based on availability and application-specific requirements.

The ERA-6ARW222V demonstrates a superior temperature coefficient specification (±10ppm/°C versus ±25ppm/°C), which provides enhanced frequency stability and reduced drift over the operating temperature range. This characteristic is advantageous in precision analog circuits and frequency-dependent applications.

The RG2012P-222-W-T5 includes anti-sulfur coating as an explicit feature, providing additional protection in corrosive environments. This distinction should be evaluated against specific application environmental exposure requirements.

Both components maintain identical electrical performance, mechanical compatibility, and regulatory compliance. The maximum seated height difference (0.50mm versus 0.60mm) is within typical PCB assembly tolerances and does not restrict interchangeability in standard surface-mount applications.

Frequently Asked Questions (FAQ)

Q: Can the ERA-6ARW222V replace the RG2012P-222-W-T5 in existing designs?

A: Yes. Both components share identical resistance (2.2 kOhms), tolerance (±0.05%), power rating (0.125W), package format (0805), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. PCB footprints are compatible.

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

A: The ERA-6ARW222V operates at ±10ppm/°C while the RG2012P-222-W-T5 operates at ±25ppm/°C. Lower temperature coefficient indicates reduced resistance drift across temperature variations, beneficial for precision measurement and frequency-dependent circuits. Both values remain within acceptable ranges for general-purpose automotive applications.

Q: Does the height difference affect PCB assembly?

A: The seated height difference (0.50mm versus 0.60mm) is 0.10mm. This variation is within standard PCB assembly tolerances and does not restrict component interchangeability in typical surface-mount applications. Verify clearance in designs with height-constrained layouts.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the RG2012P-222-W-T5 and ERA-6ARW222V carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and quality standards. Both are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between anti-sulfur coating and standard thin film construction?

A: Anti-sulfur coating provides additional protection against sulfur-containing atmospheric contaminants and corrosive environments. The RG2012P-222-W-T5 explicitly includes this feature. The ERA-6ARW222V does not list anti-sulfur coating as a specified feature. Select the RG2012P-222-W-T5 for applications with known sulfur exposure or corrosive environmental conditions.

Q: Are these components available in different packaging formats?

A: Both components are specified in Tape & Reel (TR) packaging format. This format is standard for automated PCB assembly processes and ensures component protection and handling consistency throughout the supply chain.
