CFR50J2R2 Equivalent & Substitute Parts

Part Overview

The CFR50J2R2 is a 2.2 Ohm, ±5% tolerance, 0.5W (1/2W) through-hole resistor with axial carbon film composition manufactured by TE Connectivity Passive Product. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component, enabling direct replacement in circuit applications without performance degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CFR50J2R2 is determined by the following critical parameters:

Electrical Specifications: Resistance value (2.2 Ohms), tolerance (±5%), and power rating (0.5W) must be identical to ensure functional equivalence in the circuit.

Composition & Technology: Carbon film composition is required to maintain electrical characteristics and frequency response consistent with the original component.

Package Configuration: Axial through-hole package with 2 terminations is mandatory for mechanical compatibility with existing PCB layouts and assembly processes.

Operating Environment: Temperature range of -55°C ~ 155°C ensures the substitute operates within the same thermal envelope as the original component.

Compliance & Certification: RoHS3 compliance is required to meet regulatory and procurement standards.

The substitute part CFR-50JB-52-2R2 meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CFR-50JB-52-2R2 manufactured by YAGEO is a direct substitute for the CFR50J2R2. Both components are Active product status with ROHS3 compliance and identical electrical specifications. The minor physical diameter variation (0.118" versus 0.130") does not impact functional performance or standard PCB assembly compatibility for axial through-hole components. The temperature coefficient specification of the YAGEO part (-500/+350ppm/°C) encompasses the TE Connectivity specification (±350ppm/°C), ensuring equivalent thermal stability across the operating range. Selection between these parts may be based on availability, packaging format (Tape & Box versus Bulk), or supply chain requirements, as both meet all electrical and compliance criteria for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can CFR-50JB-52-2R2 be used as a direct replacement for CFR50J2R2 in production assemblies?

A: Yes. Both components share identical electrical specifications (2.2 Ohms, ±5%, 0.5W), carbon film composition, axial package configuration, and operating temperature range (-55°C ~ 155°C). Both are ROHS3 compliant and carry the same ECCN and HTSUS classifications.

Q: What is the significance of the diameter difference (0.118" versus 0.130")?

A: The 0.012" diameter difference is within standard manufacturing tolerances for axial carbon film resistors and does not affect PCB hole sizing, lead spacing, or assembly compatibility. Both components maintain the same 0.354" axial length and 2-termination configuration.

Q: Are there any temperature coefficient differences that affect circuit performance?

A: The CFR-50JB-52-2R2 specifies -500/+350ppm/°C while the CFR50J2R2 specifies ±350ppm/°C. The YAGEO part's temperature coefficient range is compatible with and encompasses the TE Connectivity specification, ensuring equivalent thermal stability across the -55°C ~ 155°C operating range.

Q: What is the difference between Tape & Box and Bulk packaging?

A: Tape & Box packaging is suitable for automated pick-and-place assembly processes, while Bulk packaging is typically used for manual assembly or reel-based automated systems. Both packaging formats contain the same component; the choice depends on assembly methodology and inventory management requirements.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both CFR50J2R2 and CFR-50JB-52-2R2 are ROHS3 compliant, classified under ECCN EAR99, and assigned HTSUS code 8533.10.0065. Both are suitable for applications requiring regulatory compliance in the same jurisdictions.
