Substitute Part Grouping Explanation

Substitution eligibility for the CF1/2CT52R3R3J is determined by strict equivalence across the following critical parameters:

• Resistance value: 3.3 Ohms
• Tolerance: ±5%
• Power rating: 0.5W (1/2W)
• Composition: Carbon Film
• Package case: Axial
• Physical dimensions: 0.118" Dia x 0.335" L (3.00mm x 8.50mm)
• Operating temperature range: -55°C to 155°C
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The CF1/2C3R3J meets all electrical and mechanical equivalence criteria. The only difference is packaging configuration: the main part is supplied in Cut Tape (CT) format, while the substitute is supplied in Bulk format. Both parts are manufactured by KOA Speer Electronics, Inc., belong to the CF series, and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the CF1/2CT52R3R3J and CF1/2C3R3J are active production parts from KOA Speer Electronics, Inc., with identical electrical and mechanical specifications. Selection between these parts should be based on procurement and assembly requirements:

• The CF1/2CT52R3R3J in Cut Tape packaging is suitable for automated pick-and-place assembly processes.
• The CF1/2C3R3J in Bulk packaging is suitable for manual assembly or applications where tape packaging is not required.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for end-use applications. The choice between Cut Tape and Bulk packaging does not affect electrical performance, thermal characteristics, or safety ratings.

Frequently Asked Questions (FAQ)

Q: Can CF1/2C3R3J replace CF1/2CT52R3R3J in my circuit design?

A: Yes. Both parts are electrically and mechanically equivalent. The CF1/2C3R3J provides identical resistance value (3.3 Ohms ±5%), power rating (0.5W), operating temperature range (-55°C to 155°C), and physical dimensions (0.118" Dia x 0.335" L). The only difference is packaging format.

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

A: Cut Tape (CT) packaging supplies components on adhesive tape in cut lengths, optimized for automated assembly equipment. Bulk packaging supplies loose components, suitable for manual assembly or applications where tape is not required. Electrical and mechanical performance are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both CF1/2CT52R3R3J and CF1/2C3R3J are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for restricted substances.

Q: Can I use these resistors in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -55°C to 155°C, supporting applications across this temperature range.

Q: Are there any inventory considerations when selecting between these parts?

A: Inventory levels may vary. CF1/2CT52R3R3J has 4733 pcs in stock, while CF1/2C3R3J has 2077 pcs in stock. Availability should be confirmed based on project timeline and volume requirements.
