CF14JA910K Equivalent & Substitute Parts

Part Overview

The CF14JA910K is a 910 kOhms ±5% 0.25W (1/4W) 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 values across industrial and commercial temperature ranges. The part is currently active in production with full RoHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CF14JA910K is determined by the following critical parameters:

• Resistance Value: Must be 910 kOhms
• Tolerance: Must be ±5%
• Composition: Must be Carbon Film
• Package Type: Must be Axial
• Operating Temperature Range: Must support -55°C to 155°C
• Temperature Coefficient: Must be -850 ppm/°C or equivalent
• Compliance: Must maintain RoHS3 compliance

The CFM12JT910K qualifies as a substitute based on matching all electrical specifications and mechanical form factor. The primary difference is an increased power rating (0.5W vs. 0.25W), which represents an upgrade path for applications requiring higher power dissipation capability while maintaining identical resistance and tolerance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the CF14JA910K and CFM12JT910K are active production parts with full RoHS3 compliance and REACH unaffected status. Selection between these parts depends on application power dissipation requirements:

• CF14JA910K: Select for applications with power dissipation up to 0.25W and space-constrained designs requiring the shorter axial length (6.00mm).
• CFM12JT910K: Select for applications requiring power dissipation up to 0.5W or when higher thermal margin is desired. The slightly longer axial length (6.50mm) remains compatible with standard through-hole PCB layouts.

Both parts maintain identical electrical performance across the specified operating temperature range and are suitable for direct substitution where power rating requirements permit.

Frequently Asked Questions (FAQ)

Q: Can CFM12JT910K replace CF14JA910K in any application?

A: The CFM12JT910K can replace CF14JA910K in applications where the 0.5W power rating meets or exceeds the circuit requirement. The higher power rating does not degrade performance in lower-power applications. Physical dimensions differ by 0.02" (0.50mm) in length; verify PCB layout clearance before substitution.

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

A: The CF and CFM series both represent Stackpole carbon film axial resistors with identical electrical specifications for this 910 kOhms ±5% value. The series designation reflects different power rating classifications within the product line.

Q: Are there packaging differences between these parts?

A: CF14JA910K is supplied in Tape & Box (TB) format, while CFM12JT910K is supplied in Cut Tape (CT) format. Both are standard packaging options for through-hole components and do not affect electrical performance or PCB assembly compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CF14JA910K and CFM12JT910K are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8533.10.0065).
