PCF14JT2M40 Equivalent & Substitute Parts

Part Overview

The PCF14JT2M40 is a 2.4 MOhms ±5% 0.25W carbon film through-hole resistor manufactured by Stackpole Electronics Inc. This component is designed for general-purpose electronic applications requiring high-resistance values with standard tolerance and power dissipation characteristics. The part is currently in active production status with robust inventory availability. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility can be maintained across different packaging formats while preserving core functional performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCF14JT2M40 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.4 MOhms (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 / -1500ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Physical dimensions: 0.091" Dia × 0.236" L (exact match required)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected (exact match required)

The primary variable among qualified substitutes is packaging format (Tape & Reel versus Cut Tape), which does not affect electrical performance or mechanical fit in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both PCF14JT2M40 and CF14JT2M40 are active production components from Stackpole Electronics Inc with identical electrical specifications and mechanical dimensions. Selection between these parts should be based on procurement and assembly requirements:

The PCF14JT2M40 is supplied in Tape & Reel format, suitable for automated pick-and-place assembly operations. The CF14JT2M40 is supplied in Cut Tape format, appropriate for manual assembly or lower-volume production runs. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for restricted substance control. Inventory availability is significantly higher for the CF14JT2M40 variant, which may influence lead time considerations in supply chain planning.

Frequently Asked Questions (FAQ)

Q: Can CF14JT2M40 be used as a direct replacement for PCF14JT2M40?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: PCF14JT2M40 uses Tape & Reel while CF14JT2M40 uses Cut Tape. This distinction affects only the procurement and assembly process, not circuit performance.

Q: What determines if a resistor can substitute for the PCF14JT2M40?

A: A substitute must match all of the following: 2.4 MOhms resistance, ±5% tolerance, 0.25W power rating, carbon film composition, 0/-1500ppm/°C temperature coefficient, -55°C to 155°C operating range, axial through-hole package, 0.091" Dia × 0.236" L dimensions, and ROHS3/REACH compliance status.

Q: Does packaging format affect circuit performance?

A: No. Tape & Reel and Cut Tape packaging formats contain identical components. The packaging difference is relevant only to assembly methodology and supply chain logistics.

Q: Are there any compliance differences between these parts?

A: No. Both PCF14JT2M40 and CF14JT2M40 carry identical ROHS3 compliance and REACH unaffected status.

Q: Which part should be selected for automated assembly?

A: PCF14JT2M40 in Tape & Reel format is optimized for automated pick-and-place equipment. CF14JT2M40 in Cut Tape format is suitable for manual assembly or lower-volume applications.
