Substitute Part Grouping Explanation

Substitution between CF12JT820K and CFM12JT820K is based on electrical equivalence and mechanical compatibility within the axial resistor category. Both parts share identical electrical specifications: 820 kOhms resistance, ±5% tolerance, 0.5W power rating, carbon film composition, and operating temperature range of -55°C to 155°C. The primary difference is packaging format: CF12JT820K is supplied in Tape & Reel (TR) format, while CFM12JT820K is supplied in Cut Tape (CT) format. Both maintain the same component series designation and comply with identical regulatory standards (RoHS3, REACH Unaffected, EAR99). Physical dimensions vary slightly due to manufacturing tolerances within the axial package specification, but both are functionally interchangeable in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CF12JT820K and CFM12JT820K are active production parts from Stackpole Electronics Inc with full RoHS3 compliance and REACH Unaffected status. Selection between these parts should be based on packaging requirements and supply chain availability. The CF12JT820K in Tape & Reel format is suitable for high-volume automated assembly operations. The CFM12JT820K in Cut Tape format accommodates lower-volume production runs or manual assembly processes. Both parts meet identical electrical performance criteria and regulatory certifications, making them directly interchangeable from a circuit design perspective.

Frequently Asked Questions (FAQ)

Q: Can CFM12JT820K replace CF12JT820K in production? A: Yes. Both parts are electrically identical with matching resistance values, tolerances, power ratings, and operating temperature ranges. The difference is packaging format only: Tape & Reel versus Cut Tape.

Q: Are there physical dimension differences between these parts? A: Minor dimensional variations exist within axial package tolerances. CF12JT820K measures 0.106" diameter × 0.335" length; CFM12JT820K measures 0.091" diameter × 0.256" length. Both fit standard axial component footprints in PCB designs.

Q: Do both parts meet the same compliance standards? A: Yes. Both CF12JT820K and CFM12JT820K are RoHS3 compliant, REACH Unaffected, and classified as EAR99 for export purposes.

Q: Which packaging format should I specify for my application? A: Tape & Reel (TR) format is standard for automated pick-and-place assembly. Cut Tape (CT) format is used for manual assembly or lower-volume production where component feeding automation is not required.

Q: Are the temperature coefficients identical? A: Yes. Both parts share the same temperature coefficient specification of 0 / -850ppm/°C across the -55°C to 155°C operating range.
