Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CFS1/2C222J are identified based on electrical parameter equivalence and mechanical compatibility. The primary substitution criterion is the maintenance of identical electrical specifications: 2.2 kOhms resistance value, ±5% tolerance, and 0.5W power rating. All substitute parts retain the same axial package configuration, physical dimensions (0.112" Dia × 0.248" L), carbon film composition, temperature coefficient (-450/+350 ppm/°C), and operating temperature range (-55°C to +155°C).

The key differentiator among equivalent parts is packaging format. The CFS1/2C222J is supplied in Tape & Reel (TR) format, while substitute parts may be available in alternative packaging configurations such as Cut Tape (CT). Both packaging formats contain identical components with no electrical or mechanical differences. Additional features such as Flame Proof and Safety certifications on substitute parts represent enhanced specifications that do not affect base electrical performance or compatibility.

All substitute parts maintain compliance with RoHS3 and REACH regulations, ensuring regulatory equivalence for applications requiring these certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CFS1/2C222J and CFS1/2CT26A222J are Active products from KOA Speer Electronics, Inc., ensuring continued manufacturer support and availability. Selection between these parts is determined by packaging requirements and application-specific feature needs.

The CFS1/2C222J in Tape & Reel format is suitable for high-volume automated assembly operations where continuous reel feeding is required. The CFS1/2CT26A222J in Cut Tape format accommodates lower-volume production runs, manual assembly processes, or applications where individual component handling is preferred.

The CFS1/2CT26A222J includes Flame Proof and Safety certifications, making it the appropriate selection for applications subject to safety standards or flame-resistance requirements. When such certifications are not required, either part provides equivalent electrical performance.

Both parts maintain full compliance with RoHS3 and REACH regulations, supporting applications in regulated industries and markets with environmental compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can CFS1/2CT26A222J be used as a direct replacement for CFS1/2C222J?

A: Yes. Both parts are electrically and mechanically identical, with 2.2 kOhms resistance, ±5% tolerance, 0.5W power rating, and identical physical dimensions. The primary difference is packaging format (Cut Tape versus Tape & Reel).

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

A: Tape & Reel (TR) packaging supplies components on continuous reels for automated assembly equipment. Cut Tape (CT) packaging provides components on tape segments, suitable for manual assembly or lower-volume applications. Both formats contain identical components with no electrical differences.

Q: Are the Flame Proof and Safety features on CFS1/2CT26A222J required for all applications?

A: No. These features represent enhanced specifications for applications subject to specific safety or flame-resistance standards. For general-purpose applications without such requirements, the standard CFS1/2C222J provides equivalent electrical performance.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both CFS1/2C222J and CFS1/2CT26A222J are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory requirements for environmental and hazardous substance compliance.

Q: What is the temperature coefficient specification, and does it differ between parts?

A: The temperature coefficient is -450/+350 ppm/°C for both parts, indicating identical temperature stability characteristics across the operating range of -55°C to +155°C.

Q: Are there any dimensional differences between the substitute parts?

A: No. Both parts share identical physical dimensions of 0.112" Dia × 0.248" L (2.85mm × 6.30mm), ensuring compatibility with identical PCB layouts and mechanical mounting configurations.
