PRNF14FTD1K02 Equivalent & Substitute Parts

Part Overview

The PRNF14FTD1K02 is a 1.02 kOhms ±1% 0.25W through-hole resistor manufactured by Stackpole Electronics Inc in the RNF series. This metal film axial resistor features flame retardant coating and safety construction, designed for applications requiring precision resistance values with tight tolerance specifications. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct or upgraded component replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PRNF14FTD1K02 are qualified based on the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 1.02 kOhms (exact match required)
• Tolerance: ±1% (maintains precision specifications)
• Composition: Metal Film (ensures performance characteristics)

Mechanical Compatibility:

• Package type: Axial configuration (physical form factor)
• Termination count: 2 (standard through-hole leads)

Environmental & Compliance Alignment:

• Operating temperature range must encompass or match the original specification
• RoHS3 compliance required
• REACH unaffected status maintained

Two substitute parts meet these criteria: RNF14FTD1K02 (direct equivalent) and CMF551K0200FHEB (upgraded alternative with enhanced power rating).

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD1K02 (Direct Equivalent): This Stackpole Electronics part provides identical electrical and mechanical specifications to the PRNF14FTD1K02. Both parts maintain the same 0.25W power rating, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. Selection of this substitute is appropriate for direct replacement in existing designs without circuit modification. Both parts carry ROHS3 compliance and REACH unaffected status.

CMF551K0200FHEB (Upgraded Alternative): This Vishay Dale resistor offers enhanced specifications including doubled power rating (0.5W vs 0.25W), improved temperature coefficient (±50ppm/°C vs ±100ppm/°C), and extended operating temperature range (-55°C ~ 175°C vs -55°C ~ 155°C). The CMF551K0200FHEB maintains identical resistance value, tolerance, and axial package configuration. This upgrade is suitable for applications requiring improved thermal performance or higher power dissipation margins. ROHS3 compliance and REACH unaffected status are maintained.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD1K02 be used as a direct replacement for PRNF14FTD1K02?

A: Yes. Both parts are manufactured by Stackpole Electronics Inc with identical electrical specifications (1.02 kOhms ±1%, 0.25W), metal film composition, axial package configuration, and operating temperature range (-55°C ~ 155°C). Direct substitution is supported without circuit redesign.

Q: What are the advantages of using CMF551K0200FHEB over the original PRNF14FTD1K02?

A: The CMF551K0200FHEB provides three performance enhancements: doubled power rating (0.5W vs 0.25W) for improved thermal margin, superior temperature coefficient (±50ppm/°C vs ±100ppm/°C) for better stability, and extended operating temperature range (up to 175°C vs 155°C). Resistance value and tolerance remain identical at 1.02 kOhms ±1%.

Q: Are all substitute parts physically compatible with the original PCB footprint?

A: All three parts use axial package configuration with 2 terminations. Physical dimensions are comparable (PRNF14FTD1K02: 0.093" Dia x 0.250" L; CMF551K0200FHEB: 0.090" Dia x 0.240" L), ensuring compatibility with standard through-hole PCB layouts designed for 1/4W or 1/2W axial resistors.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. PRNF14FTD1K02, RNF14FTD1K02, and CMF551K0200FHEB all carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Q: Which substitute should be selected for high-temperature applications?

A: CMF551K0200FHEB is specified for operation up to 175°C, compared to 155°C for the original PRNF14FTD1K02. Selection of the Vishay Dale part is appropriate for applications requiring extended high-temperature performance.
