Key Parameters

Substitute Part Grouping Explanation

Substitution between CF12JT910K and CFM12JT910K is valid based on the following criteria:

Electrical Parameters (Identical):

• Resistance value: 910 kOhms
• Tolerance: ±5%
• Power rating: 0.5W
• Composition: Carbon Film
• Temperature coefficient: 0 / -850ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Compatible):

• Package type: Axial (both parts)
• Number of terminations: 2 (both parts)
• Features: Flame Retardant Coating, Safety (both parts)

Compliance Parameters (Identical):

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99
• HTSUS: 8533.10.0065

The primary difference is packaging format: CF12JT910K is supplied in Tape & Reel (TR) format, while CFM12JT910K is supplied in Cut Tape (CT) format. Physical dimensions vary slightly due to manufacturing tolerances within the axial package specification.

Parameter Comparison

Engineering Selection Recommendations

Both CF12JT910K and CFM12JT910K are active production parts from Stackpole Electronics Inc with identical electrical specifications and full regulatory compliance. Selection between these parts is determined by packaging and supply chain requirements rather than electrical performance.

CF12JT910K in Tape & Reel format is suitable for high-volume automated assembly operations. CFM12JT910K in Cut Tape format accommodates lower-volume applications, manual assembly processes, or situations where individual component access is required.

Both parts meet ROHS3 compliance and REACH requirements, ensuring compatibility with current environmental regulations. The identical temperature coefficient and operating range guarantee consistent performance across specified thermal conditions.

Frequently Asked Questions (FAQ)

Q: Can CFM12JT910K be used as a direct replacement for CF12JT910K in circuit applications?

A: Yes. Both parts have identical electrical specifications: 910 kOhms resistance, ±5% tolerance, 0.5W power rating, and identical temperature characteristics. They are electrically interchangeable in all circuit applications.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for manual assembly or lower-volume production runs.

Q: Are the physical dimensions of these parts identical?

A: Both parts use the axial package type with 2 terminations. CF12JT910K has dimensions of 0.106" Dia x 0.335" L (2.70mm x 8.50mm), while CFM12JT910K has dimensions of 0.091" Dia x 0.256" L (2.30mm x 6.50mm). These dimensional variations are within acceptable tolerances for axial through-hole resistor mounting on standard PCB layouts.

Q: Do both parts meet current compliance requirements?

A: Yes. Both CF12JT910K and CFM12JT910K are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Which part should be selected for new designs?

A: Selection depends on manufacturing process requirements. For automated assembly with high-volume production, CF12JT910K (Tape & Reel) is standard. For manual assembly, prototyping, or lower-volume applications, CFM12JT910K (Cut Tape) is appropriate. Both are active production parts with equivalent long-term availability.
