RT0805CRE07105RL Equivalent & Substitute Parts

Part Overview

The RT0805CRE07105RL is a 105 Ohms ±0.25% thin film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This surface mount device is rated for 0.125W (1/8W) power dissipation with an operating temperature range of -55°C to 155°C. The part is currently active in production and ROHS3 compliant. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design requirements necessitate alternative specifications such as improved tolerance or enhanced reliability ratings.

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805CRE07105RL is determined by the following criteria:

Mandatory Parameters (Must Match):

• Resistance value: 105 Ohms
• Package type: 0805 (2012 Metric)
• Composition: Thin Film
• Termination count: 2
• Operating temperature range: -55°C to 155°C minimum
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variations:

• Tolerance: May be equal to or tighter (lower) than ±0.25%
• Power rating: May be equal to or higher than 0.125W
• Temperature coefficient: May be equal to or lower than ±50ppm/°C
• RoHS compliance: Must maintain or exceed current compliance level
• Regulatory certifications: Additional certifications (such as AEC-Q200) are permissible

Two substitute parts meet these criteria and are grouped as follows:

Direct Substitute (Electrical Upgrade): 2-2176091-6 by TE Connectivity Passive Product offers improved tolerance (±0.1%) and higher power rating (0.25W) while maintaining the same package and operating temperature range.

Upgrade Substitute (Automotive-Grade): ERA-6AEB1050V by Panasonic Electronic Components provides improved tolerance (±0.1%), automotive AEC-Q200 qualification, and ROHS3 compliance, while maintaining the original power rating and package specifications.

Parameter Comparison

Engineering Selection Recommendations

For Standard Applications: The RT0805CRE07105RL remains the primary choice for general-purpose circuits where the specified tolerance and power rating are adequate.

For Improved Tolerance Requirements: The ERA-6AEB1050V is the preferred substitute when tighter tolerance (±0.1%) is required. This part maintains ROHS3 compliance and adds automotive-grade AEC-Q200 qualification, making it suitable for both commercial and automotive applications.

For Higher Power Dissipation: The 2-2176091-6 offers increased power handling (0.25W) and improved tolerance (±0.1%), but does not maintain RoHS compliance. This part is suitable only for applications where RoHS compliance is not a regulatory requirement.

For Automotive Applications: The ERA-6AEB1050V is the only substitute with AEC-Q200 automotive qualification and is the appropriate choice for automotive circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the 2-2176091-6 be used as a direct replacement for the RT0805CRE07105RL?

A: Electrically, yes. Both parts share the same 105 Ohm resistance value, 0805 package, and operating temperature range. However, the 2-2176091-6 is not RoHS compliant, which may disqualify it from applications requiring regulatory compliance.

Q: What is the advantage of the ERA-6AEB1050V over the main part?

A: The ERA-6AEB1050V provides three advantages: tighter tolerance (±0.1% versus ±0.25%), lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), and AEC-Q200 automotive qualification. It maintains ROHS3 compliance and the same power rating and package.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and two terminations. Maximum seated heights are within 0.002" (0.05mm) of each other, making them suitable for the same PCB layout.

Q: Which substitute should be selected for a new design?

A: For new designs, the ERA-6AEB1050V is recommended. It provides improved tolerance and temperature stability while maintaining full RoHS3 compliance and adding automotive-grade reliability certification.

Q: Can the higher power-rated 2-2176091-6 replace the RT0805CRE07105RL in all applications?

A: From a thermal perspective, the higher power rating (0.25W versus 0.125W) provides additional margin. However, the lack of RoHS compliance and undefined REACH status make this part unsuitable for applications with regulatory compliance requirements.
