Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCF14JT18K0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 18 kOhms
• Tolerance: ±5%
• Power rating: 0.25W (1/4W)
• Composition: Carbon Film
• Temperature coefficient: 0 / -500ppm/°C
• Operating temperature range: -55°C to 155°C
• Flame retardant coating and safety features
• RoHS3 compliance
• REACH unaffected status

All substitute parts listed maintain identical electrical specifications and regulatory compliance. Differences exist only in packaging format (Tape & Reel versus Cut Tape) and physical dimensions, which do not affect electrical performance or functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—PCF14JT18K0, CF14JT18K0, and CFM14JT18K0—are active products from Stackpole Electronics Inc with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

1. Packaging requirements: PCF14JT18K0 is supplied in Tape & Reel format suitable for automated assembly processes. CF14JT18K0 and CFM14JT18K0 are supplied in Cut Tape format for manual or semi-automated handling.

2. Physical dimensions: PCF14JT18K0 and CF14JT18K0 share identical dimensions (0.091" Dia x 0.236" L). CFM14JT18K0 is a miniaturized variant (0.067" Dia x 0.130" L) suitable for space-constrained applications.

3. Inventory availability: CF14JT18K0 offers the highest stock level (109,528 pcs), followed by CFM14JT18K0 (20,058 pcs) and PCF14JT18K0 (958 pcs).

All parts maintain identical electrical performance and regulatory compliance across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can CF14JT18K0 be used as a direct replacement for PCF14JT18K0?

A: Yes. Both parts are electrically identical with matching resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The primary difference is packaging format: PCF14JT18K0 uses Tape & Reel while CF14JT18K0 uses Cut Tape. Physical dimensions are identical.

Q: What is the key difference between CFM14JT18K0 and the other two parts?

A: CFM14JT18K0 is a miniaturized variant from the CFM series with smaller physical dimensions (0.067" Dia x 0.130" L versus 0.091" Dia x 0.236" L). All electrical specifications remain identical. Use CFM14JT18K0 when space constraints require a smaller component footprint.

Q: Are all three parts RoHS3 compliant?

A: Yes. PCF14JT18K0, CF14JT18K0, and CFM14JT18K0 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and Cut Tape formats are supply and handling methods only. They do not affect the electrical characteristics, performance, or reliability of the resistor component itself.

Q: Which part should be selected for high-volume automated assembly?

A: PCF14JT18K0 in Tape & Reel format is optimized for automated pick-and-place assembly processes. CF14JT18K0 in Cut Tape format is suitable for semi-automated or manual assembly operations.
