Key Parameters

Substitute Part Grouping Explanation

Substitution for the PRNF14FTD1K33 is determined by the following critical parameters:

• Resistance value: 1.33 kOhms
• Tolerance: ±1%
• Composition: Metal Film
• Package configuration: Axial through-hole
• Compliance: RoHS3 Compliant

Direct substitutes maintain identical electrical specifications and packaging. Upgrade substitutes may feature enhanced power ratings, improved temperature coefficients, or extended operating temperature ranges while preserving the core electrical and mechanical compatibility required for circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

The RNF14FTD1K33 serves as a direct substitute, maintaining identical electrical and mechanical specifications with equivalent Active product status and RoHS3 compliance. Packaging differs only in tape format (Cut Tape versus Tape & Reel), which does not affect circuit performance.

The CMF551K3300FHEB represents an upgrade substitute option. This component maintains the same resistance value, tolerance, and axial package configuration while providing enhanced specifications: increased power rating (0.5W versus 0.25W), extended operating temperature range (-55°C to 175°C versus -55°C to 155°C), and improved temperature coefficient (±50ppm/°C versus ±100ppm/°C). The addition of moisture-resistant features provides supplementary environmental protection. All components maintain RoHS3 compliance and Active product status.

Frequently Asked Questions (FAQ)

Q: Can the RNF14FTD1K33 be used as a direct replacement for PRNF14FTD1K33?

A: Yes. Both components share identical electrical specifications (1.33 kOhms ±1%, 0.25W metal film), axial package configuration, and compliance certifications. The difference in packaging format (Cut Tape versus Tape & Reel) does not affect electrical performance or board-level compatibility.

Q: When should the CMF551K3300FHEB upgrade substitute be selected?

A: The CMF551K3300FHEB is appropriate when circuit design requires higher power dissipation capability (0.5W rating), operation at elevated temperatures above 155°C, or improved temperature stability (±50ppm/°C). The axial package maintains mechanical compatibility with existing board layouts designed for the PRNF14FTD1K33.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The PRNF14FTD1K33, RNF14FTD1K33, and CMF551K3300FHEB all carry RoHS3 Compliant certification and are classified as Active products.

Q: What is the significance of the temperature coefficient difference between substitutes?

A: The temperature coefficient indicates resistance value drift with temperature change. The CMF551K3300FHEB exhibits ±50ppm/°C compared to ±100ppm/°C for the main part and direct substitute. This means the CMF part maintains more stable resistance across the operating temperature range, beneficial for precision circuit applications.

Q: Do packaging format differences affect circuit board integration?

A: No. Cut Tape (CT) and Tape & Reel (TR) packaging formats represent different supply methods for the same component. Once removed from packaging, the axial resistor dimensions and electrical characteristics remain identical, ensuring equivalent board-level performance.
