PCF14JT18R0 Equivalent & Substitute Parts

Part Overview

The PCF14JT18R0 is an 18 Ohms ±5% 0.25W through-hole resistor manufactured by Stackpole Electronics Inc in the CF series. This carbon film resistor features flame retardant coating and safety characteristics, designed for axial or radial bend configurations. The part is Active status and ROHS3 compliant. Substitute parts may be required due to packaging format differences, inventory availability, or specific application requirements for alternative form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PCF14JT18R0 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Parameters: Resistance value (18 Ohms), tolerance (±5%), power rating (0.25W), composition (carbon film), temperature coefficient (0 / -400ppm/°C), and operating temperature range (-55°C ~ 155°C) must remain identical.

Mechanical Parameters: Package type and form factor may vary. The main part PCF14JT18R0 is supplied in Tape & Reel (TR) packaging with axial or radial bend configuration. Substitute parts may be available in Cut Tape (CT) packaging with axial configuration only, provided all electrical specifications remain unchanged.

Compliance Parameters: RoHS3 compliance and REACH unaffected status must be maintained across all substitutes.

Parameter Comparison

Engineering Selection Recommendations

All three parts—PCF14JT18R0, CF14JT18R0, and CFM14JT18R0—maintain identical electrical specifications and are Active status products with full ROHS3 compliance and REACH unaffected certification.

CF14JT18R0 is a direct electrical equivalent supplied in Cut Tape packaging instead of Tape & Reel, with identical physical dimensions (0.091" Dia x 0.236" L). This substitute is suitable for applications where Cut Tape packaging is acceptable and axial configuration is required.

CFM14JT18R0 is an alternative from the CFM series with identical electrical performance but reduced physical dimensions (0.067" Dia x 0.130" L). This substitute is applicable only when space constraints permit the smaller form factor and axial configuration is compatible with the circuit design.

Frequently Asked Questions (FAQ)

Q: Can CF14JT18R0 replace PCF14JT18R0 in production? A: Yes. CF14JT18R0 is electrically identical with the same resistance, tolerance, power rating, and temperature characteristics. The difference is packaging format (Cut Tape vs. Tape & Reel) and configuration limitation (axial only vs. axial/radial bend). Verify your assembly process accepts Cut Tape format and axial configuration.

Q: What is the key difference between CF14JT18R0 and CFM14JT18R0? A: Both are electrically equivalent 18 Ohm ±5% 0.25W resistors. The primary difference is physical size: CF14JT18R0 measures 0.091" Dia x 0.236" L, while CFM14JT18R0 measures 0.067" Dia x 0.130" L. CFM14JT18R0 is suitable only for applications with space constraints that accommodate the smaller form factor.

Q: Are all three parts RoHS compliant? A: Yes. PCF14JT18R0, CF14JT18R0, and CFM14JT18R0 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can CFM14JT18R0 be used if PCF14JT18R0 is specified? A: Only if the circuit board layout and component placement accommodate the smaller dimensions (0.067" Dia x 0.130" L vs. 0.091" Dia x 0.236" L). Electrical performance is identical, but physical fit must be verified.

Q: What packaging formats are available? A: PCF14JT18R0 is supplied in Tape & Reel (TR) format. CF14JT18R0 and CFM14JT18R0 are supplied in Cut Tape (CT) format. Verify your procurement and assembly processes support the required packaging.
