RT0402BRE07105RL Equivalent & Substitute Parts

Part Overview

The RT0402BRE07105RL is a 105 Ohm thin film chip resistor manufactured by YAGEO in the 0402 (1005 Metric) package format. This component is rated at ±0.1% tolerance with 0.063W power handling capability and operates across the -55°C to 155°C temperature range. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support design flexibility, supply chain continuity, and application-specific requirements such as automotive qualification or enhanced temperature coefficient performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402BRE07105RL is determined by strict equivalence across the following parameters: resistance value (105 Ohms), tolerance (±0.1%), power rating (0.063W), thin film composition, 0402 package format, operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3, REACH status). The identified substitute parts meet all these core electrical and mechanical requirements. Temperature coefficient variations (±50ppm/°C vs. ±25ppm/°C) and automotive qualification (AEC-Q200) represent secondary differentiators that do not prevent substitution but indicate enhanced performance characteristics for specific applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and full RoHS3 compliance, establishing baseline compatibility for general applications. The CPF0402B105RE1 from TE Connectivity offers improved temperature coefficient performance (±25ppm/°C) compared to the original RT0402BRE07105RL (±50ppm/°C) while maintaining identical electrical specifications and package dimensions, making it suitable for precision applications requiring tighter temperature stability. The ERA-2AEB1050X from Panasonic provides AEC-Q200 automotive qualification with equivalent temperature coefficient performance (±25ppm/°C) and is appropriate for automotive and high-reliability applications where formal qualification documentation is required. The maximum seated height of the ERA-2AEB1050X (0.016" / 0.40mm) is marginally higher than the other two options (0.014" / 0.35mm), which may be a consideration in space-constrained PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B105RE1 be used as a direct replacement for RT0402BRE07105RL?

A: Yes. Both parts share identical resistance (105 Ohms), tolerance (±0.1%), power rating (0.063W), thin film composition, 0402 package format, and operating temperature range (-55°C to 155°C). The CPF0402B105RE1 features a superior temperature coefficient (±25ppm/°C vs. ±50ppm/°C), which represents an enhancement rather than a limitation for substitution.

Q: Is ERA-2AEB1050X suitable for non-automotive applications?

A: Yes. The ERA-2AEB1050X meets all electrical and mechanical requirements for the RT0402BRE07105RL and is not restricted to automotive use. The AEC-Q200 qualification is an additional certification that does not prevent application in general-purpose circuits. The 0.016" (0.40mm) maximum seated height should be verified against PCB layout constraints.

Q: What is the significance of the temperature coefficient difference?

A: Temperature coefficient indicates resistance value drift across the operating temperature range. The ±25ppm/°C specification of CPF0402B105RE1 and ERA-2AEB1050X provides tighter tolerance maintenance across temperature extremes compared to the ±50ppm/°C of RT0402BRE07105RL. This is beneficial for precision analog circuits but not a requirement for general switching or biasing applications.

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

A: All three parts are supplied in Tape & Reel (TR) format with 0402 (1005 Metric) package specification. The seated height of ERA-2AEB1050X is 0.016" (0.40mm) maximum compared to 0.014" (0.35mm) for the other two parts. This difference should be evaluated against PCB design clearance requirements.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. RT0402BRE07105RL, CPF0402B105RE1, and ERA-2AEB1050X are all ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage protocols.
