PCF14JT100K Equivalent & Substitute Parts

Part Overview

The PCF14JT100K is a 100 kOhms ±5% 0.25W carbon film through-hole resistor manufactured by Stackpole Electronics Inc. This component is classified as Active product status and is designed for general-purpose resistive applications requiring flame retardant coating and safety features. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit designs, particularly when packaging format or inventory availability differs from the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCF14JT100K are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Resistance value: 100 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Carbon Film (exact match required)
• Temperature coefficient: 0 / -850ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Mechanical Compatibility Criteria:

• Package type: Axial configuration (primary criterion)
• Number of terminations: 2 (exact match required)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected (exact match required)

Packaging Format Variations: Substitutes may differ in packaging delivery format (Tape & Reel vs. Cut Tape) and physical dimensions while maintaining electrical equivalence and axial package compatibility.

Parameter Comparison

Engineering Selection Recommendations

CF14JT100K (Direct Substitute): This part maintains identical electrical specifications and primary physical dimensions to the PCF14JT100K. The primary difference is packaging format (Cut Tape vs. Tape & Reel). Both parts are Active status products with ROHS3 compliance and REACH unaffected certification. Selection of CF14JT100K is appropriate when Cut Tape packaging is acceptable for assembly processes.

CFM14JT100K (Manufacturer Recommended Substitute): This part is designated as the manufacturer-recommended alternative and maintains all electrical specifications identical to the PCF14JT100K. The CFM series represents a compact variant with reduced physical dimensions (0.067" Dia x 0.130" L vs. 0.091" Dia x 0.236" L). Both parts are Active status with ROHS3 compliance and REACH unaffected certification. Selection of CFM14JT100K is appropriate when space constraints or compact board layouts require smaller component footprint while maintaining electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can CF14JT100K replace PCF14JT100K in all applications? A: Yes. CF14JT100K maintains identical electrical specifications (100 kOhms ±5%, 0.25W, carbon film composition, temperature coefficient, and operating range) and mechanical compatibility (axial package, 2 terminations). The difference is packaging format (Cut Tape vs. Tape & Reel), which does not affect circuit performance.

Q: What is the primary difference between PCF14JT100K and CFM14JT100K? A: Both parts have identical electrical specifications. The CFM14JT100K is a compact variant with smaller physical dimensions (0.067" Dia x 0.130" L compared to 0.091" Dia x 0.236" L). This makes CFM14JT100K suitable for space-constrained applications while maintaining full electrical equivalence.

Q: Are all three parts ROHS3 compliant? A: Yes. PCF14JT100K, CF14JT100K, and CFM14JT100K are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can CFM14JT100K be used in place of PCF14JT100K on existing PCBs? A: CFM14JT100K has different physical dimensions and may not fit existing PCB footprints designed for the standard-size CF series. PCB layout compatibility must be verified before substitution.

Q: What packaging formats are available for these parts? A: PCF14JT100K is supplied in Tape & Reel (TR) format. CF14JT100K and CFM14JT100K are supplied in Cut Tape (CT) format. Packaging format selection depends on assembly process requirements and does not affect electrical performance.
