Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CF1/4C473J is determined by the following critical parameters:

Electrical Specifications: Resistance value (47 kOhms), tolerance (±5%), and power rating (0.25W) must be identical. These parameters ensure functional equivalence in circuit operation.

Physical Form Factor: Package type (Axial) and termination count (2) must match to ensure mechanical compatibility with existing PCB layouts and through-hole mounting requirements.

Environmental Compliance: Operating temperature range (-55°C ~ 155°C) and RoHS3 compliance status must be maintained to satisfy regulatory and thermal operating requirements.

Composition: Carbon film composition is required to maintain electrical characteristics including temperature coefficient behavior within acceptable ranges for the application.

The substitute part CF14JT47K0 meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the CF1/4C473J and CF14JT47K0 are Active product status components with ROHS3 compliance and REACH Unaffected designation. The CF14JT47K0 includes flame retardant coating and safety features in its carbon film construction, providing additional protection characteristics. Physical dimensions are compatible within standard PCB through-hole tolerances, with the CF14JT47K0 measuring 0.004" shorter in length. Both components satisfy identical electrical and thermal operating requirements across the -55°C ~ 155°C range. Selection between these parts is based on availability, packaging format preference (Bulk versus Cut Tape), and application-specific requirements for flame retardant properties.

Frequently Asked Questions (FAQ)

Q: Can CF14JT47K0 be used as a direct replacement for CF1/4C473J?

A: Yes. Both components share identical resistance (47 kOhms), tolerance (±5%), power rating (0.25W), composition (carbon film), package type (axial), operating temperature range (-55°C ~ 155°C), and RoHS3 compliance status. Physical dimensions are compatible with standard through-hole PCB mounting.

Q: What is the difference between these two 47 kOhm resistors?

A: The primary differences are manufacturer (KOA Speer versus Stackpole), packaging format (Bulk versus Cut Tape), and construction features. The CF14JT47K0 includes flame retardant coating and safety features. Physical length differs by 0.004" (0.10mm), which does not affect PCB compatibility.

Q: Are the temperature coefficients equivalent?

A: Temperature coefficients differ slightly. The CF1/4C473J specifies -450/+350 ppm/°C while the CF14JT47K0 specifies 0/-500 ppm/°C. Both operate within the identical -55°C ~ 155°C temperature range and maintain ±5% tolerance across this range.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Bulk versus Cut Tape) affects handling, storage, and assembly processes but does not alter electrical specifications or performance characteristics.

Q: Are both parts RoHS3 compliant?

A: Yes. Both CF1/4C473J and CF14JT47K0 are ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and use.
