RG2012P-3243-B-T5 Equivalent & Substitute Parts

Part Overview

The RG2012P-3243-B-T5 is a 324 kOhms ±0.1% thin film chip resistor manufactured by Susumu in 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and features anti-sulfur coating with automotive AEC-Q200 qualification. The part is actively produced and maintained in inventory. Substitute parts are identified to provide alternative sourcing options when the primary manufacturer part becomes unavailable or when supply chain optimization is required.

Substitute Part Grouping Explanation

Substitution of the RG2012P-3243-B-T5 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 324 kOhms (exact match required)
• Tolerance: ±0.1% (precision specification)
• Power Rating: 0.125W / 1/8W (thermal capability)
• Package Format: 0805 (2012 Metric) (physical and electrical footprint)
• Composition: Thin Film (performance characteristics)
• Temperature Coefficient: ±25ppm/°C (stability specification)
• Operating Temperature Range: -55°C ~ 155°C (environmental limits)
• Automotive Qualification: AEC-Q200 (reliability standard)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The ERA-6AEB3243V from Panasonic Electronic Components meets all critical electrical and mechanical parameters required for direct substitution. Both parts share identical resistance, tolerance, power rating, package format, temperature coefficient, and operating temperature range. Both components carry AEC-Q200 automotive qualification and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the RG2012P-3243-B-T5 and ERA-6AEB3243V are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical performance differences.

The RG2012P-3243-B-T5 features anti-sulfur coating, which provides enhanced environmental protection in corrosive atmospheres. The ERA-6AEB3243V does not specify anti-sulfur treatment in the provided parameters.

The maximum seated height differs slightly between the two parts: RG2012P-3243-B-T5 at 0.020" (0.50mm) versus ERA-6AEB3243V at 0.024" (0.60mm). This 0.004" (0.10mm) difference is within typical PCB assembly tolerances for 0805 package components and does not affect functional compatibility in standard applications.

Both components are suitable for direct substitution in circuits requiring 324 kOhms ±0.1% precision resistors with automotive-grade reliability in the -55°C to 155°C operating range.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB3243V replace RG2012P-3243-B-T5 in automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification, identical electrical specifications (324 kOhms ±0.1%, ±25ppm/°C), and the same operating temperature range (-55°C ~ 155°C). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference in physical height between these parts?

A: The RG2012P-3243-B-T5 has a maximum seated height of 0.020" (0.50mm), while the ERA-6AEB3243V measures 0.024" (0.60mm) maximum. This 0.004" (0.10mm) difference is within standard PCB assembly tolerances for 0805 components and does not affect board-level compatibility.

Q: Are both parts available in the same packaging format?

A: Yes. Both the RG2012P-3243-B-T5 and ERA-6AEB3243V are supplied in Tape & Reel (TR) packaging in 0805 (2012 Metric) format with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm).

Q: What is the significance of the anti-sulfur feature on the RG2012P-3243-B-T5?

A: The anti-sulfur coating on the RG2012P-3243-B-T5 provides enhanced resistance to sulfur-containing environmental contaminants. This feature is specified for the Susumu part but not listed in the provided parameters for the Panasonic ERA-6AEB3243V. Applications in high-sulfur environments may require the anti-sulfur variant.

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

A: Yes. Both the RG2012P-3243-B-T5 and ERA-6AEB3243V are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030.

Q: What is the tolerance specification for these resistors?

A: Both parts are specified at ±0.1% tolerance, which is a precision thin film specification suitable for applications requiring tight resistance accuracy.

Q: Are these parts suitable for high-temperature applications?

A: Yes. Both components are rated for operation across the -55°C to 155°C temperature range with a temperature coefficient of ±25ppm/°C, making them suitable for automotive and industrial high-temperature environments.
