Engineering Selection Recommendations

All three part numbers—CF1/4CVTPA100J, CF1/4CT52R100J, and CFP1/4CT52R100J—are active production components manufactured by KOA Speer Electronics, Inc., and maintain full ROHS3 compliance. Selection between these parts should be based on:

Inventory availability: CF1/4CT52R100J offers the highest stock level at 98,561 units, providing superior supply chain continuity.
Feature requirements: CF1/4CVTPA100J and CFP1/4CT52R100J both include flame-proof and safety features. CF1/4CT52R100J does not specify these features and should be selected only when flame-proof characteristics are not required.
Packaging format: All three parts are supplied in Cut Tape (CT) packaging, ensuring consistent handling and assembly compatibility.

All substitute parts maintain identical electrical performance, physical dimensions, and environmental operating specifications, enabling direct functional replacement within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can CF1/4CT52R100J be used as a direct replacement for CF1/4CVTPA100J?

A: CF1/4CT52R100J is electrically and mechanically equivalent in all specified parameters. However, it does not include flame-proof and safety features. Use this substitute only in applications where these features are not required.

Q: What is the difference between CF1/4CVTPA100J and CFP1/4CT52R100J?

A: Both parts are identical in electrical specifications, physical dimensions, and operating characteristics. Both include flame-proof and safety features. The primary difference is inventory availability: CF1/4CVTPA100J has 2907 units in stock, while CFP1/4CT52R100J has 6143 units.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All three parts share identical axial package dimensions of 0.091" Dia x 0.240" L (2.30mm x 6.10mm) and two terminations, ensuring compatibility with the same through-hole PCB layout.

Q: Do all parts meet the same compliance standards?

A: Yes. CF1/4CVTPA100J, CF1/4CT52R100J, and CFP1/4CT52R100J are all ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.10.0065.

Q: What is the temperature coefficient difference between these parts?

A: All three parts share identical temperature coefficient specifications of -450/+350 ppm/°C and operate across the same temperature range of -55°C to 155°C.

Q: Which substitute should I select for high-reliability applications?

A: For applications requiring flame-proof and safety characteristics, select either CF1/4CVTPA100J or CFP1/4CT52R100J. Both provide these features. For general-purpose applications without flame-proof requirements, CF1/4CT52R100J is acceptable and offers superior inventory availability.
