Key Parameters

Substitute Part Grouping Explanation

Substitution of the CFS1/2CT52R472J is based on electrical and mechanical parameter equivalence within the CF series. The primary substitute, CFS1/2CT26A472J, maintains identical electrical specifications: 4.7 kOhms resistance, ±5% tolerance, 0.5W power rating, carbon film composition, and operating temperature range of -55°C to 155°C. Both parts feature the same axial package configuration with identical physical dimensions (0.112" Dia x 0.248" L) and two terminations.

The key differentiator between these parts is packaging format and additional features. The main part (CFS1/2CT52R472J) is supplied in Tape & Reel (TR) format, while the substitute (CFS1/2CT26A472J) is supplied in Cut Tape (CT) format. The substitute includes flame-proof and safety features not specified for the main part. Both parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8533.10.0065.

Substitution is valid when packaging format flexibility is acceptable and flame-proof construction is either required or neutral to the application.

Parameter Comparison

Engineering Selection Recommendations

Both the CFS1/2CT52R472J and CFS1/2CT26A472J are Active products from KOA Speer Electronics, Inc., ensuring continued manufacturer support and availability. Selection between these parts is determined by packaging and feature requirements rather than electrical performance.

CFS1/2CT52R472J is appropriate for applications where Tape & Reel packaging is specified for automated assembly processes or when bulk reel quantities are required.

CFS1/2CT26A472J is appropriate for applications where Cut Tape packaging is acceptable, flame-proof construction is required or beneficial, or when smaller quantity procurement is necessary. The flame-proof and safety features of the substitute provide additional protection in applications where thermal stress or safety certification is a consideration.

Both parts maintain identical electrical characteristics, temperature stability, and regulatory compliance (RoHS3, REACH unaffected, EAR99 classification). Physical dimensions and termination configuration are identical, ensuring direct mechanical compatibility in through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can CFS1/2CT26A472J be used as a direct replacement for CFS1/2CT52R472J?

A: Yes. Both parts have identical electrical specifications (4.7 kOhms ±5%, 0.5W), identical physical dimensions (0.112" Dia x 0.248" L), identical axial package configuration, and identical operating temperature range (-55°C to 155°C). The primary difference is packaging format (Cut Tape versus Tape & Reel) and the addition of flame-proof and safety features in the substitute.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, suitable for lower-volume applications or manual assembly. Both formats use identical component specifications and dimensions.

Q: Are the flame-proof and safety features of CFS1/2CT26A472J compatible with applications designed for CFS1/2CT52R472J?

A: Yes. Flame-proof and safety features are additional protective characteristics that do not conflict with standard resistor applications. These features provide enhanced performance in thermal stress conditions and are compatible with all applications designed for standard carbon film resistors.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both CFS1/2CT52R472J and CFS1/2CT26A472J are RoHS3 compliant, REACH unaffected, and classified as EAR99 under export control regulations. Both carry identical HTSUS code 8533.10.0065.

Q: Are the temperature coefficients identical between these parts?

A: Yes. Both parts have identical temperature coefficient specifications of -450/+350 ppm/°C and identical operating temperature range of -55°C to 155°C.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts have identical axial package configuration, identical physical dimensions, and identical two-termination design. They are mechanically and electrically interchangeable in through-hole PCB applications.
