CF18JA82K0 Equivalent & Substitute Parts

Part Overview

The CF18JA82K0 is an 82 kOhms ±5% 0.125W (1/8W) through-hole axial resistor manufactured by Stackpole Electronics Inc. This carbon film resistor features flame retardant coating and safety characteristics, designed for general-purpose applications requiring reliable performance across industrial temperature ranges. The part is currently active in production with 811 units in stock. Substitute parts are identified to address inventory availability, packaging format preferences, or power rating requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CF18JA82K0 is determined by the following critical parameters:

• Resistance Value: Must be 82 kOhms
• Tolerance: Must be ±5%
• Composition: Must be Carbon Film
• Package / Case: Must be Axial
• Operating Temperature Range: Must support -55°C ~ 155°C
• Temperature Coefficient: Must be 0 / -500ppm/°C
• RoHS Compliance: Must maintain ROHS3 Compliant status

The CFM14JA82K0 qualifies as a substitute part because it maintains all critical electrical parameters (resistance, tolerance, composition, temperature range, and temperature coefficient) and mechanical compatibility (axial package). The primary difference is the power rating upgrade from 0.125W to 0.25W, which represents a functional enhancement rather than a limitation. Both parts are manufactured by Stackpole Electronics Inc and share identical RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both CF18JA82K0 and CFM14JA82K0 are active production parts with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

• Power Dissipation Requirements: The CFM14JA82K0 provides double the power rating (0.25W vs 0.125W), suitable for applications with higher thermal stress or safety margin requirements.
• Packaging Availability: CF18JA82K0 is supplied in Tape & Box format with 811 units in stock; CFM14JA82K0 is supplied in Cut Tape format with 6788 units in stock.
• Regulatory Compliance: Both parts maintain identical ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification.

The CFM14JA82K0 is a direct functional upgrade suitable for any application originally designed for the CF18JA82K0, with no electrical or mechanical incompatibilities.

Frequently Asked Questions (FAQ)

Q: Can CFM14JA82K0 replace CF18JA82K0 in existing designs?

A: Yes. The CFM14JA82K0 maintains identical resistance (82 kOhms), tolerance (±5%), composition (carbon film), package type (axial), operating temperature range (-55°C ~ 155°C), and temperature coefficient (0 / -500ppm/°C). The increased power rating (0.25W vs 0.125W) represents a functional enhancement with no compatibility issues.

Q: What is the primary difference between these two parts?

A: The CFM14JA82K0 has a higher power rating of 0.25W (1/4W) compared to the CF18JA82K0 at 0.125W (1/8W). All other electrical and mechanical parameters are identical.

Q: Are there packaging format differences?

A: Yes. The CF18JA82K0 is supplied in Tape & Box (TB) format, while the CFM14JA82K0 is supplied in Cut Tape (CT) format. Both are axial through-hole components with identical physical dimensions (0.067" Dia x 0.130" L).

Q: Do both parts meet the same compliance standards?

A: Yes. Both CF18JA82K0 and CFM14JA82K0 are ROHS3 compliant, REACH Unaffected, and classified as EAR99 under ECCN regulations.

Q: Which part should be selected for new designs?

A: For new designs, the CFM14JA82K0 is recommended due to higher inventory availability (6788 units vs 811 units) and the power rating advantage, which provides additional thermal margin without any electrical or mechanical trade-offs.
