Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRNF14FTD27K4 is determined by strict equivalence across the following critical parameters:

• Resistance value: 27.4 kOhms
• Tolerance classification: ±1%
• Power dissipation rating: 0.25W (1/4W)
• Composition type: Metal Film
• Package configuration: Axial leads
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Regulatory compliance: RoHS3 Compliant, REACH Unaffected

The identified substitute part RNF14FTD27K4 matches all electrical and mechanical parameters. The only distinction is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is available in Cut Tape (CT) format. Both formats contain identical components with identical specifications and are suitable for equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The RNF14FTD27K4 substitute part is electrically and mechanically equivalent to the PRNF14FTD27K4 main part. Both components are manufactured by Stackpole Electronics Inc, maintain Active product status, and carry identical electrical specifications including resistance value, tolerance, power rating, and temperature characteristics. Both parts satisfy RoHS3 compliance and REACH unaffected requirements for regulated applications.

The distinction between the two part numbers reflects packaging format only: Tape & Reel versus Cut Tape. This difference does not affect component performance or electrical characteristics. Selection between these formats depends on assembly process requirements and inventory management practices rather than functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD27K4 (Cut Tape) be used in place of PRNF14FTD27K4 (Tape & Reel)?

A: Yes. Both parts contain identical resistor components with matching electrical specifications. The packaging format difference does not affect circuit performance. Selection depends on assembly equipment compatibility and supply chain requirements.

Q: Are the electrical specifications identical between the main part and substitute?

A: Yes. Both parts specify 27.4 kOhms ±1% resistance, 0.25W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Metal film composition and axial package configuration are identical.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both PRNF14FTD27K4 and RNF14FTD27K4 are RoHS3 compliant and REACH unaffected, suitable for applications requiring these certifications.

Q: What is the physical compatibility between these parts?

A: Both parts share identical dimensions of 0.093" diameter by 0.250" length (2.35mm × 6.35mm) with two axial terminations. PCB footprints and mounting requirements are identical.

Q: Why are there two part numbers for the same component?

A: The part numbers reflect different packaging and supply formats. PRNF14FTD27K4 is supplied in Tape & Reel format for automated assembly lines, while RNF14FTD27K4 is supplied in Cut Tape format for manual assembly or smaller volume requirements. The resistor component itself is identical.
