Key Parameters

Substitute Part Grouping Explanation

The CFF12JA100R is identified as a parametric equivalent to the CF12JA100R based on the following matching criteria:

• Identical resistance value: 100 Ohms
• Identical tolerance: ±5%
• Identical power rating: 0.5W (1/2W)
• Identical composition: Carbon Film
• Identical package type: Axial
• Identical operating temperature range: -55°C to 155°C
• Identical temperature coefficient: 0 / -400ppm/°C
• Identical physical dimensions: 0.106" Dia × 0.335" L (2.70mm × 8.50mm)
• Identical termination count: 2
• Identical compliance certifications: ROHS3 Compliant, REACH Unaffected

The primary difference between these parts is the packaging format (Tape & Box versus Cut Tape) and the flame protection feature designation (Flame Retardant Coating versus Flame Proof). Both parts maintain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both CF12JA100R and CFF12JA100R are active production parts from Stackpole Electronics Inc with identical electrical specifications and full regulatory compliance. Selection between these parts should be based on packaging requirements and supply chain considerations:

• CF12JA100R (Tape & Box) is suitable for applications requiring bulk packaging and storage
• CFF12JA100R (Cut Tape) is suitable for automated assembly processes and applications with lower volume requirements

Both parts satisfy ROHS3 and REACH compliance requirements and are suitable for deployment in equivalent circuit applications across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CFF12JA100R be used as a direct replacement for CF12JA100R?

A: Yes. Both parts have identical electrical characteristics (100 Ohms, ±5%, 0.5W), identical physical dimensions (0.106" Dia × 0.335" L), and identical operating specifications. The difference is packaging format only.

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

A: Tape & Box (TB) packaging provides resistors on continuous tape wound on a reel and boxed for storage. Cut Tape (CT) packaging provides resistors on tape segments cut to specific lengths. Both formats contain the same component; the choice depends on assembly equipment compatibility and volume requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both CF12JA100R and CFF12JA100R are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: Do these parts have identical temperature performance?

A: Yes. Both parts operate across -55°C to 155°C with identical temperature coefficient specifications of 0 / -400ppm/°C, ensuring equivalent thermal stability in circuit applications.

Q: What is the difference between Flame Retardant Coating and Flame Proof?

A: Both designations indicate fire safety features. Flame Retardant Coating slows flame propagation, while Flame Proof provides enhanced fire resistance. Both meet safety requirements for their respective product lines.
