Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-1540-P-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 154 Ohms
• Package format: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W) minimum
• Composition: Thin film construction
• Operating temperature range: -55°C to 155°C minimum
• Automotive qualification: AEC-Q200

Allowable Variation Parameters:

• Tolerance: Equal to or tighter than ±0.02%
• Temperature coefficient: Equal to or lower absolute value
• Packaging format: Tape & Reel acceptable for obsolete part replacement
• Manufacturer: Alternative qualified suppliers permitted

The RG2012V-1540-P-T1 qualifies as a direct upgrade substitute, maintaining identical electrical specifications while offering improved temperature coefficient performance and active product status. The ERA-6AEB1540V qualifies as a functional equivalent substitute with relaxed tolerance specification (±0.1% versus ±0.02%), suitable for applications where the tighter tolerance of the original part is not required.

Parameter Comparison

Engineering Selection Recommendations

RG2012V-1540-P-T1 (Susumu): This part is the recommended primary substitute for the obsolete RG2012N-1540-P-T1. It maintains identical electrical specifications including 154 Ohm resistance and ±0.02% tolerance while offering superior temperature coefficient performance (±5ppm/°C versus ±10ppm/°C). The part carries active product status with AEC-Q200 automotive qualification and ROHS3 compliance. Packaging is supplied in Tape & Reel format, standard for production environments.

ERA-6AEB1540V (Panasonic Electronic Components): This part functions as an alternative equivalent substitute where tolerance relaxation to ±0.1% is acceptable for the application. The part maintains identical 154 Ohm resistance, 0.125W power rating, 0805 package format, and AEC-Q200 automotive qualification. Temperature coefficient is ±25ppm/°C, representing a trade-off in thermal stability. This option provides high inventory availability (9108 units) and active product status. Selection of this part requires confirmation that the ±0.1% tolerance specification meets circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can the RG2012V-1540-P-T1 be used as a direct replacement for the RG2012N-1540-P-T1?

A: Yes. The RG2012V-1540-P-T1 maintains identical electrical specifications (154 Ohms ±0.02%, 0.125W, 0805 package) and automotive qualifications. The primary difference is improved temperature coefficient performance (±5ppm/°C versus ±10ppm/°C) and active product status. Both parts are manufactured by Susumu and are mechanically and electrically compatible.

Q: What is the tolerance difference between the main part and the ERA-6AEB1540V substitute?

A: The RG2012N-1540-P-T1 specifies ±0.02% tolerance, while the ERA-6AEB1540V specifies ±0.1% tolerance. This represents a five-fold relaxation in tolerance specification. The ERA-6AEB1540V is suitable for applications where this broader tolerance band is acceptable. Applications requiring precision matching or tight tolerance control should use the RG2012V-1540-P-T1 instead.

Q: Are all substitute parts available in the same packaging format?

A: The RG2012N-1540-P-T1 packaging format is not specified in the available data. Both substitute parts (RG2012V-1540-P-T1 and ERA-6AEB1540V) are supplied in Tape & Reel (TR) format, which is standard for production assembly. Confirm packaging compatibility with your assembly process requirements.

Q: Do all parts meet automotive qualification standards?

A: Yes. The RG2012N-1540-P-T1, RG2012V-1540-P-T1, and ERA-6AEB1540V all carry AEC-Q200 automotive qualification. All three parts are ROHS3 compliant and REACH unaffected, meeting automotive and environmental regulatory requirements.

Q: What is the temperature coefficient difference between substitute options?

A: The RG2012N-1540-P-T1 has a temperature coefficient of ±10ppm/°C. The RG2012V-1540-P-T1 offers improved performance at ±5ppm/°C. The ERA-6AEB1540V has a temperature coefficient of ±25ppm/°C. For applications sensitive to temperature-induced resistance drift, the RG2012V-1540-P-T1 provides superior stability.

Q: Why is the RG2012N-1540-P-T1 classified as obsolete?

A: The RG2012N-1540-P-T1 is listed as obsolete by the manufacturer. The RG2012V-1540-P-T1 represents the active product line continuation from Susumu with equivalent or superior specifications. For new designs and ongoing procurement, the RG2012V-1540-P-T1 is the recommended standard.
