CFR-25JR-52-2R Equivalent & Substitute Parts

Part Overview

The CFR-25JR-52-2R is a 2 Ohm, ±5% tolerance, 1/4W (0.25W) through-hole resistor with axial carbon film composition manufactured by YAGEO. This component is classified as Active product status with full RoHS3 compliance. Substitute parts are identified to address packaging format availability, inventory requirements, or supply chain continuity while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CFR-25JR-52-2R is determined by strict equivalence across the following critical parameters:

• Resistance value: 2 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.25W/1/4W (exact match required)
• Composition: Carbon Film (exact match required)
• Package/Case: Axial (exact match required)
• Temperature coefficient: -500/+350 ppm/°C (exact match required)
• Operating temperature range: -55°C to +155°C (exact match required)
• Physical dimensions: 0.094" Dia × 0.248" L (exact match required)

The identified substitute part CFR-25JB-52-2R meets all electrical and mechanical equivalence criteria. The primary distinction is packaging format: CFR-25JR-52-2R is supplied in Cut Tape (CT) format, while CFR-25JB-52-2R is supplied in Bulk format. Both parts are manufactured by YAGEO within the same CFR series and maintain identical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both CFR-25JR-52-2R and CFR-25JB-52-2R are Active status components with full ROHS3 compliance and REACH Unaffected certification. Selection between these parts is based on packaging requirements and inventory availability rather than electrical performance. The CFR-25JR-52-2R in Cut Tape format is suitable for automated pick-and-place assembly operations. The CFR-25JB-52-2R in Bulk format accommodates manual assembly workflows or high-volume applications requiring loose component handling. Both parts are functionally interchangeable in circuit applications where the 2 Ohm, ±5%, 1/4W axial resistor specification is required.

Frequently Asked Questions (FAQ)

Q: Can CFR-25JB-52-2R replace CFR-25JR-52-2R in my circuit design?

A: Yes. Both parts are electrically and mechanically equivalent. The CFR-25JB-52-2R meets all specified parameters: 2 Ohm resistance, ±5% tolerance, 0.25W power rating, carbon film composition, axial package, and identical temperature characteristics. The only difference is packaging format (Bulk vs. Cut Tape).

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

A: Cut Tape (CT) packaging supplies components on continuous tape that is cut into individual segments, optimized for automated assembly equipment. Bulk packaging supplies loose components, suitable for manual assembly or applications where tape format is not required.

Q: Are both parts RoHS compliant?

A: Yes. Both CFR-25JR-52-2R and CFR-25JB-52-2R are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: Do these resistors have identical thermal performance?

A: Yes. Both parts share identical temperature coefficient (-500/+350 ppm/°C) and operating temperature range (-55°C to +155°C), ensuring equivalent thermal stability and performance across the specified operating conditions.

Q: Can I use these parts interchangeably in PCB assembly?

A: Yes, provided your assembly process accommodates the packaging format. If your process uses automated tape-fed equipment, use CFR-25JR-52-2R. If manual placement or bulk handling is required, use CFR-25JB-52-2R. Electrical performance is identical.
