• Composition: Carbon Film
• Package: Axial through-hole
• Temperature coefficient: 0 / -500ppm/°C
• Operating temperature range: -55°C to 155°C
• Compliance: RoHS3 Compliant

The CF12JA82K0 meets all substitution criteria as a manufacturer-recommended equivalent. Both parts are produced by Stackpole Electronics Inc and share identical electrical and thermal specifications. Physical dimensions vary slightly between the two part numbers, reflecting different manufacturing series within the same product category.

Parameter Comparison

Engineering Selection Recommendations

Both CFM12JA82K0 and CF12JA82K0 are active production parts with full RoHS3 compliance and REACH unaffected status. Selection between these parts depends on physical space constraints within the application. The CFM12JA82K0 features a smaller form factor (2.30mm diameter × 6.50mm length), while the CF12JA82K0 is slightly larger (2.70mm diameter × 8.50mm length). All electrical and thermal characteristics remain identical across both part numbers. Both parts carry ECCN EAR99 classification and HTSUS code 8533.10.0065.

Frequently Asked Questions (FAQ)

Q: Can CF12JA82K0 be used as a direct replacement for CFM12JA82K0?

A: Yes. Both parts share identical electrical specifications, tolerance, power rating, temperature coefficient, and operating temperature range. The primary difference is physical dimension. CF12JA82K0 is slightly larger and may require layout verification if space is constrained.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN and HTSUS classifications.

Q: What is the significance of the different part number series (CFM vs. CF)?

A: The series designation reflects different manufacturing lines within Stackpole Electronics Inc's product portfolio. Both series produce carbon film resistors with identical electrical and thermal performance for this 82 kOhm 0.5W specification.

Q: Does the physical size difference affect electrical performance?

A: No. The dimensional variation does not impact resistance value, tolerance, power dissipation capability, or temperature coefficient. Size differences are manufacturing-related and do not alter functional characteristics.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across the -55°C to 155°C temperature range with identical temperature coefficient specifications, making them suitable for industrial and extended-temperature applications.
