Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTE100K are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 100 kOhms (exact match required)
• Tolerance: ±1% or better (tighter tolerance acceptable)
• Temperature coefficient: ±25ppm/°C (matching specification)
• Composition: Metal film (maintains electrical characteristics)

Mechanical Parameters (Critical):

• Package type: Axial through-hole (physical compatibility)
• Termination count: 2 (standard axial configuration)

Regulatory & Compliance (Required):

• RoHS3 compliance (environmental standard)
• ECCN EAR99 classification (export control consistency)

Acceptable Variations:

• Power rating: May be equal or higher (0.25W or greater)
• Operating temperature range: May be equal or wider
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) acceptable
• Flame retardant features: Flame Retardant or Flame Proof both acceptable

Parameter Comparison

Engineering Selection Recommendations

RNF14BTE100K (Stackpole Electronics Inc): This substitute provides tighter tolerance (±0.1% versus ±1%) while maintaining identical power rating, temperature coefficient, and operating temperature range. Both components are from the same manufacturer within the RNF series. Physical dimensions and axial package configuration are identical. ROHS3 compliance and EAR99 classification are maintained. Selection of this part is appropriate when enhanced tolerance performance is required without thermal or power derating concerns.

CPF1100K00FEEE6 (Vishay Dale): This substitute provides higher power rating (1W versus 0.25W) and extended operating temperature range (-65°C to 230°C versus -55°C to 155°C). Resistance, tolerance, and temperature coefficient specifications match the main part. Physical dimensions show minor variation (0.090" Dia x 0.240" L versus 0.093" Dia x 0.250" L), remaining within typical axial through-hole PCB footprint compatibility. ROHS3 compliance and EAR99 classification are maintained. Selection of this part is appropriate for applications requiring higher thermal dissipation capability or extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can RNF14BTE100K be used as a direct replacement for RNF14FTE100K?

A: Yes. Both components share identical resistance (100 kOhms), power rating (0.25W), temperature coefficient (±25ppm/°C), operating temperature range (-55°C to 155°C), physical dimensions (0.093" Dia x 0.250" L), and axial package configuration. The RNF14BTE100K provides superior tolerance (±0.1% versus ±1%). Both are ROHS3 compliant and EAR99 classified. The primary difference is packaging format (Cut Tape versus Tape & Reel).

Q: What are the key differences between RNF14FTE100K and CPF1100K00FEEE6?

A: Both maintain 100 kOhms resistance, ±1% tolerance, and ±25ppm/°C temperature coefficient. The CPF1100K00FEEE6 provides higher power rating (1W versus 0.25W) and wider operating temperature range (-65°C to 230°C versus -55°C to 155°C). Physical dimensions differ slightly (0.090" Dia x 0.240" L versus 0.093" Dia x 0.250" L). Both are ROHS3 compliant and EAR99 classified.

Q: Are there mechanical compatibility concerns when substituting these parts?

A: All three components use axial through-hole package configuration with 2 terminations. Physical dimensions are comparable, with CPF1100K00FEEE6 showing minor dimensional variation (0.090" Dia x 0.240" L versus 0.093" Dia x 0.250" L). These variations remain within standard axial resistor PCB footprint tolerances and do not present mechanical compatibility issues.

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

A: CPF1100K00FEEE6 is specified for operating temperatures up to 230°C, compared to 155°C for RNF14FTE100K and RNF14BTE100K. Selection of CPF1100K00FEEE6 is appropriate when extended temperature operation is required.

Q: Do all substitute parts maintain regulatory compliance?

A: Yes. RNF14FTE100K, RNF14BTE100K, and CPF1100K00FEEE6 are all ROHS3 compliant and EAR99 classified, maintaining consistent regulatory status across all qualified substitutes.
