Key Parameters

Substitute Part Grouping Explanation

The CFM14JA82R0 qualifies as a substitute for the CF18JA82R0 based on the following matching electrical and mechanical parameters:

• Resistance value: 82 Ohms (identical)
• Tolerance: ±5% (identical)
• Composition: Carbon Film (identical)
• Package type: Axial (identical)
• Operating temperature range: -55°C to 155°C (identical)
• Temperature coefficient: 0 / -400 ppm/°C (identical)
• RoHS compliance: ROHS3 Compliant (identical)
• Manufacturer: Stackpole Electronics Inc (same manufacturer)

The primary difference is the power rating: CFM14JA82R0 is rated at 0.25W (1/4W) compared to the CF18JA82R0 at 0.125W (1/8W). A higher power rating provides additional thermal margin and is electrically compatible in applications designed for the lower power specification.

Parameter Comparison

Engineering Selection Recommendations

Both the CF18JA82R0 and CFM14JA82R0 are active production parts from Stackpole Electronics Inc with identical RoHS3 compliance status. The CFM14JA82R0 provides a higher power dissipation capability (0.25W versus 0.125W) while maintaining all other electrical and mechanical specifications. Selection between these parts depends on circuit power requirements and available board space. Both parts meet the same regulatory and compliance requirements for applications requiring ROHS3-compliant carbon film resistors.
