RG2012P-1050-D-T5 Equivalent & Substitute Parts

Part Overview

The RG2012P-1050-D-T5 is a 105 Ohm thin film chip resistor manufactured by Susumu in 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation with ±0.5% tolerance and features automotive AEC-Q200 qualification with anti-sulfur coating. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support component availability, design flexibility, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-1050-D-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 105 Ohms
• Package format: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±0.5% or tighter (±0.1% acceptable)
• Power rating: 0.125W or higher (0.25W acceptable)
• Automotive qualification: AEC-Q200 preferred but not mandatory for all applications
• RoHS compliance: ROHS3 preferred

The identified substitute parts meet the mandatory matching parameters. Variations in tolerance and power rating represent either equivalent or upgraded specifications suitable for direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

ERA-6AEB1050V (Panasonic Electronic Components): This part functions as an upgrade substitute. It maintains identical resistance, package, and operating temperature specifications while providing tighter tolerance (±0.1% versus ±0.5%) and matching automotive AEC-Q200 qualification. ROHS3 compliance is retained. The seated height increases from 0.50mm to 0.60mm, which remains within typical PCB design clearances for 0805 packages. This substitute is suitable for applications requiring enhanced tolerance performance without design modification.

2-2176091-6 (TE Connectivity Passive Product): This part functions as a direct substitute with equivalent resistance and package specifications. Tolerance is tightened to ±0.1%, and power rating is increased to 0.25W (1/4W), providing additional thermal margin. The seated height increases to 0.65mm. RoHS compliance status is non-compliant, which may restrict use in applications with mandatory ROHS3 requirements. This substitute is suitable for applications where RoHS compliance is not a design constraint and where increased power dissipation capability is beneficial.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB1050V replace RG2012P-1050-D-T5 in automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification, operate across -55°C to 155°C, and share identical 0805 package dimensions and thin film composition. The tighter tolerance of ERA-6AEB1050V (±0.1%) provides enhanced accuracy compared to the main part (±0.5%).

Q: What is the impact of the height difference between substitute parts?

A: The main part has a maximum seated height of 0.50mm. ERA-6AEB1050V measures 0.60mm, and 2-2176091-6 measures 0.65mm. These differences fall within standard 0805 package tolerances and do not affect PCB layout compatibility for typical surface mount assembly processes.

Q: Is 2-2176091-6 suitable for RoHS-compliant applications?

A: No. The 2-2176091-6 is marked as RoHS non-compliant. Applications requiring ROHS3 compliance must use either the main part RG2012P-1050-D-T5 or the substitute ERA-6AEB1050V, both of which are ROHS3 compliant.

Q: What is the functional difference between ±0.5% and ±0.1% tolerance?

A: Tolerance defines the maximum deviation from the nominal 105 Ohm resistance value. At ±0.5%, the resistance range is 104.475 to 105.525 Ohms. At ±0.1%, the range is 104.895 to 105.105 Ohms. Tighter tolerance (±0.1%) is suitable for precision circuits requiring closer resistance matching.

Q: Can 2-2176091-6 be used where RG2012P-1050-D-T5 is specified?

A: Functional substitution is possible based on matching resistance, package, and operating temperature. However, the RoHS non-compliance status and absence of automotive AEC-Q200 qualification must be evaluated against application requirements. The increased power rating (0.25W versus 0.125W) provides additional thermal capability.

Q: Are all three parts electrically interchangeable?

A: All three parts share identical resistance (105 Ohms), package (0805), composition (thin film), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C to 155°C). Tolerance and power rating variations represent specification enhancements rather than functional incompatibilities. Electrical interchangeability is confirmed for these parameters.
