Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-4871-P-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 4.87 kOhms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Operating temperature range: -55°C ~ 155°C
• Automotive AEC-Q200 qualification
• RoHS3 compliance
• Thin film composition

Allowable Variation Parameters:

• Tolerance: Substitute parts may have equal or tighter tolerance specifications
• Temperature coefficient: Substitute parts may have equal or lower temperature coefficient values
• Packaging format: Tape & Reel (TR) packaging is compatible with the original component specifications
• Product status: Active status parts are preferred for obsolete components

The RG2012V-4871-P-T1 qualifies as an upgrade substitute with identical electrical specifications and improved temperature coefficient performance. The ERA-6AEB4871V qualifies as a similar substitute with relaxed tolerance specification but equivalent core functionality.

Parameter Comparison

Engineering Selection Recommendations

RG2012V-4871-P-T1 (Upgrade Substitute): This component is the primary recommended substitute for the obsolete RG2012P-4871-P-T1. Both parts are manufactured by Susumu and share identical electrical specifications including 4.87 kOhms resistance, ±0.02% tolerance, and 0.125W power rating. The RG2012V-4871-P-T1 offers superior temperature coefficient performance (±5ppm/°C versus ±25ppm/°C), providing enhanced stability across the full operating temperature range. The part maintains active product status with full AEC-Q200 automotive qualification and ROHS3 compliance. Tape & Reel packaging format is standard for production environments.

ERA-6AEB4871V (Similar Substitute): This Panasonic component provides functional equivalence with relaxed tolerance specification (±0.1% versus ±0.02%). Selection of this part is appropriate for applications where the tighter tolerance of the original component is not a critical design requirement. The ERA-6AEB4871V maintains identical resistance value, power rating, package format, and operating temperature range. Full AEC-Q200 automotive qualification and ROHS3 compliance are confirmed. Higher inventory availability (8790 units) supports procurement continuity.

Frequently Asked Questions (FAQ)

Q: Can the RG2012V-4871-P-T1 be used as a direct replacement for the RG2012P-4871-P-T1?

A: Yes. Both components share identical electrical specifications: 4.87 kOhms resistance, ±0.02% tolerance, 0.125W power rating, 0805 package, and -55°C to 155°C operating range. The RG2012V-4871-P-T1 provides improved temperature coefficient performance (±5ppm/°C). Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance.

Q: What is the tolerance difference between the main part and the ERA-6AEB4871V substitute?

A: The RG2012P-4871-P-T1 specifies ±0.02% tolerance, while the ERA-6AEB4871V specifies ±0.1% tolerance. This represents a 5-fold relaxation in tolerance specification. Component selection should be based on circuit design requirements for resistance accuracy.

Q: Are all three components qualified for automotive applications?

A: Yes. The RG2012P-4871-P-T1, RG2012V-4871-P-T1, and ERA-6AEB4871V all carry AEC-Q200 automotive qualification and are ROHS3 compliant.

Q: What is the physical package compatibility between these components?

A: All three components use the 0805 (2012 Metric) package format with identical footprint dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm). Physical board layout compatibility is confirmed.

Q: Why does the RG2012V-4871-P-T1 have a lower temperature coefficient than the main part?

A: The RG2012V-4871-P-T1 specifies ±5ppm/°C temperature coefficient compared to ±25ppm/°C for the RG2012P-4871-P-T1. This represents improved thermal stability characteristics in the upgraded component design.

Q: What is the moisture sensitivity rating for these components?

A: All three components carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Are there packaging format differences between the substitute parts?

A: The RG2012V-4871-P-T1 and ERA-6AEB4871V are supplied in Tape & Reel (TR) format, which is standard for production assembly environments. The original RG2012P-4871-P-T1 packaging format is not specified in available documentation.
