• Tolerance: ±5%
• Power rating: 0.25W (1/4W)
• Composition: Carbon Film
• Package configuration: Axial through-hole
• Physical dimensions: 0.091" Dia x 0.240" L (2.30mm x 6.10mm)
• Operating temperature range: -55°C ~ 155°C
• Safety and flame-proof characteristics

The identified substitute part CF1/4C206J maintains identical electrical and mechanical specifications. The primary distinction is packaging format: the main part is supplied in cut tape (CT) format, while the substitute is available in bulk packaging. Both parts are manufactured by KOA Speer Electronics, Inc., share the same CF series designation, and carry equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both CF1/4CT52R206J and CF1/4C206J are active production parts manufactured by KOA Speer Electronics, Inc., with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and supply chain considerations:

The CF1/4CT52R206J in cut tape packaging is suitable for automated assembly processes requiring tape-and-reel or cut tape formats. The CF1/4C206J in bulk packaging accommodates manual assembly, kit assembly, or applications where packaging format flexibility is required. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across industrial and commercial applications. The flame-proof and safety features are preserved across both variants, maintaining functional equivalence for high-resistance circuit applications operating within the -55°C to 155°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can CF1/4C206J be used as a direct replacement for CF1/4CT52R206J?

A: Yes. Both parts are electrically and mechanically identical, with 20 MOhms resistance, ±5% tolerance, 0.25W power rating, and identical physical dimensions. The only difference is packaging format (cut tape versus bulk). Functional performance in the circuit is equivalent.

Q: What is the primary difference between these two part numbers?

A: The CF1/4CT52R206J is supplied in cut tape (CT) packaging, while CF1/4C206J is supplied in bulk packaging. All electrical specifications, mechanical dimensions, and safety features are identical.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across the -55°C to 155°C temperature range and maintain their specified tolerance and power rating throughout this range.

Q: Do both parts meet RoHS and REACH requirements?
