Substitute Part Grouping Explanation

Substitute parts for PRNF14FTD3K01 are classified into two categories based on allowed electrical and mechanical parameters:

Direct Substitutes (Identical Electrical Performance):

• RNF14FAD3K01 and RNF14FTD3K01 maintain identical resistance (3.01 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Differentiation occurs only in packaging format: Tape & Box (TB) versus Tape & Reel (TR) versus Cut Tape (CT).

Upgrade Substitute (Enhanced Performance Envelope):

• CMF553K0100FHEB (Vishay Dale CMF series) maintains identical resistance (3.01 kOhms) and tolerance (±1%) but operates at 0.5W (1/2W) power rating with improved temperature coefficient (±50ppm/°C) and extended operating temperature range (-55°C ~ 175°C). This component qualifies as an upgrade substitute where higher power dissipation capability and tighter temperature stability are acceptable.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Identical Electrical Performance): RNF14FAD3K01 and RNF14FTD3K01 are functionally equivalent to PRNF14FTD3K01. Selection between these three parts depends solely on packaging format requirements: Tape & Box (TB) for RNF14FAD3K01, Tape & Reel (TR) for PRNF14FTD3K01, or Cut Tape (CT) for RNF14FTD3K01. All three maintain active product status and ROHS3 compliance.

For Upgrade Substitution (Enhanced Performance Envelope): CMF553K0100FHEB qualifies as an upgrade substitute where circuit design permits higher power dissipation (0.5W versus 0.25W), improved temperature stability (±50ppm/°C versus ±100ppm/°C), and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). This component maintains active product status and ROHS3 compliance. Physical dimensions differ slightly (0.090" Dia x 0.240" L versus 0.093" Dia x 0.250" L), requiring mechanical clearance verification in board layout.

Frequently Asked Questions (FAQ)

Q: Can RNF14FAD3K01 replace PRNF14FTD3K01 in production? A: Yes. Both components share identical electrical specifications (3.01 kOhms ±1%, 0.25W, metal film, ±100ppm/°C, -55°C ~ 155°C). The difference is packaging format only: Tape & Box versus Tape & Reel. Selection depends on assembly equipment compatibility and inventory management requirements.

Q: What is the difference between PRNF14FTD3K01 and RNF14FTD3K01? A: These are the same part number with different packaging formats. PRNF14FTD3K01 is supplied in Tape & Reel (TR) format, while RNF14FTD3K01 is supplied in Cut Tape (CT) format. Electrical performance is identical.

Q: Can CMF553K0100FHEB be used as a direct replacement? A: CMF553K0100FHEB is an upgrade substitute, not a direct replacement. It maintains the same resistance (3.01 kOhms) and tolerance (±1%), but operates at 0.5W power rating instead of 0.25W, with improved temperature coefficient (±50ppm/°C) and extended temperature range (-55°C ~ 175°C). Use this part only where circuit design permits higher power dissipation and the enhanced performance envelope is acceptable. Physical dimensions differ slightly, requiring board layout verification.

Q: Are all substitute parts ROHS3 compliant? A: Yes. PRNF14FTD3K01, RNF14FAD3K01, RNF14FTD3K01, and CMF553K0100FHEB are all ROHS3 compliant.

Q: What packaging formats are available for 3.01 kOhms ±1% 1/4W axial resistors? A: For Stackpole RNF series: Tape & Reel (TR) as PRNF14FTD3K01, Tape & Box (TB) as RNF14FAD3K01, and Cut Tape (CT) as RNF14FTD3K01. For Vishay Dale CMF series upgrade: Cut Tape (CT) as CMF553K0100FHEB.
