Key Parameters

Substitute Part Grouping Explanation

The CFM12JT91R0 qualifies as a direct substitute for the CF12JT91R0 based on the following matching electrical and mechanical parameters:

• Identical resistance value: 91 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 RoHS compliance: ROHS3 Compliant

The primary difference between these parts is packaging format: CF12JT91R0 is supplied in Tape & Reel (TR) format, while CFM12JT91R0 is supplied in Cut Tape (CT) format. Both parts share identical electrical specifications and physical dimensions within acceptable tolerances for axial resistor applications.

Parameter Comparison

Engineering Selection Recommendations

Both CF12JT91R0 and CFM12JT91R0 are active production components from Stackpole Electronics Inc with identical electrical specifications and full regulatory compliance. Selection between these parts should be based on assembly process requirements and packaging availability. The CF12JT91R0 in tape and reel format is suitable for high-volume automated assembly operations. The CFM12JT91R0 in cut tape format accommodates lower-volume production runs or manual assembly workflows. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can CFM12JT91R0 be used as a direct replacement for CF12JT91R0?

A: Yes. Both parts have identical electrical specifications: 91 Ohms ±5% at 0.5W power rating with carbon film composition. The difference is packaging format only—tape and reel versus cut tape.

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.

Q: Are the physical dimensions identical between these parts?

A: The electrical specifications are identical, but physical dimensions differ slightly. CF12JT91R0 measures 0.106" Dia x 0.335" L (2.70mm x 8.50mm), while CFM12JT91R0 measures 0.091" Dia x 0.256" L (2.30mm x 6.50mm). Both are axial through-hole resistors compatible with standard PCB layouts.

Q: Do both parts meet current compliance requirements?

A: Yes. Both CF12JT91R0 and CFM12JT91R0 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Which part should be selected for high-volume production?

A: CF12JT91R0 in tape and reel format is optimized for high-volume automated assembly operations.

Q: Which part should be selected for low-volume or manual assembly?

A: CFM12JT91R0 in cut tape format is suitable for lower-volume production runs or manual assembly workflows.
