CF18JA560K Equivalent & Substitute Parts

Part Overview

The CF18JA560K is a 560 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 resistance in compact form factors. The part is currently active in production with full RoHS3 compliance. Substitute parts are identified to address inventory availability, packaging preferences, or power rating requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CF18JA560K is permissible with the CFM14JA560K based on the following criteria:

Matching Parameters (Substitution Basis):

• Resistance value: 560 kOhms (identical)
• Tolerance: ±5% (identical)
• Composition: Carbon Film (identical)
• Package/Case: Axial (identical)
• Operating Temperature Range: -55°C ~ 155°C (identical)
• Temperature Coefficient: 0 / -850ppm/°C (identical)
• RoHS3 Compliance: Both parts compliant
• Manufacturer: Stackpole Electronics Inc (same manufacturer)

Differing Parameter:

• Power Rating: CF18JA560K rated at 0.125W (1/8W); CFM14JA560K rated at 0.25W (1/4W)

The CFM14JA560K represents an upgrade in power dissipation capability while maintaining all other electrical and mechanical specifications. This substitution is valid for applications where the original 1/8W rating is sufficient, as the higher power rating of the substitute provides additional thermal margin.

Parameter Comparison

Engineering Selection Recommendations

Both CF18JA560K and CFM14JA560K are active production parts with full RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component applications. The CFM14JA560K substitute offers identical electrical performance with enhanced power dissipation capability (0.25W versus 0.125W), making it suitable for applications where thermal margin is beneficial. Selection between these parts should be based on packaging requirements (Tape & Box versus Cut Tape format) and inventory availability rather than electrical performance, as both deliver equivalent functional characteristics for 560 kOhms ±5% axial resistor applications.

Frequently Asked Questions (FAQ)

Q: Can CFM14JA560K replace CF18JA560K in existing designs? A: Yes. The CFM14JA560K is electrically and mechanically compatible. The higher power rating (0.25W versus 0.125W) does not affect circuit operation and provides additional thermal headroom. Physical dimensions and axial package configuration are identical.

Q: What is the primary difference between these two parts? A: The power rating differs. CF18JA560K is rated at 0.125W (1/8W), while CFM14JA560K is rated at 0.25W (1/4W). All other specifications—resistance, tolerance, temperature range, and composition—are identical.

Q: Are both parts RoHS3 compliant? A: Yes. Both CF18JA560K and CFM14JA560K are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Does packaging format affect electrical performance? A: No. CF18JA560K is supplied in Tape & Box (TB) format, while CFM14JA560K is supplied in Cut Tape (CT) format. Packaging format does not affect electrical characteristics and is a logistics consideration only.

Q: Are these parts suitable for high-temperature applications? A: Both parts operate across the -55°C ~ 155°C temperature range with a temperature coefficient of 0 / -850ppm/°C, making them suitable for industrial and extended-temperature applications within these limits.
