Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped into two categories based on allowed electrical and mechanical parameters:

Direct Equivalent (Same Specifications):

• RNF14FTD2K00: Identical electrical specifications and physical dimensions as RNF14FAD2K00. Difference is packaging format only (Cut Tape vs. Tape & Box).

Upgrade Substitutes (Enhanced Specifications):

• CMF552K0000BEEB, CMF552K0000BHEB, CMF552K0000FHEB: All manufactured by Vishay Dale. These parts maintain the 2 kOhms resistance value and axial package type. Substitution is permitted based on the following allowed parameter variations:
  • Power rating increased from 0.25W to 0.5W (backward compatible)
  • Tolerance options: ±0.1% or ±1% (±0.1% is tighter, ±1% matches original)
  • Temperature coefficient improved to ±25ppm/°C or ±50ppm/°C (lower is better)
  • Operating temperature range extended to -55°C ~ 175°C (wider range)
  • Physical dimensions slightly reduced (0.090" Dia x 0.240" L vs. 0.093" Dia x 0.250" L)
  • Moisture resistant feature added

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD2K00 is the direct equivalent for applications where packaging format flexibility is acceptable. Both parts maintain identical electrical and thermal specifications with ROHS3 compliance and Active product status.

CMF552K0000FHEB provides a substitute option matching the original ±1% tolerance specification while offering increased power dissipation capability (0.5W vs. 0.25W) and extended operating temperature range (-55°C ~ 175°C). This part is suitable for applications requiring thermal margin or higher ambient temperature operation.

CMF552K0000BEEB and CMF552K0000BHEB are upgrade substitutes offering tighter tolerance specifications (±0.1%) with improved temperature coefficient performance. These Vishay Dale parts provide enhanced precision and thermal stability compared to the original specification. All three Vishay Dale substitutes include moisture-resistant features and are ROHS3 compliant with Active product status.

Physical dimension differences (0.090" Dia x 0.240" L vs. 0.093" Dia x 0.250" L) are minor and do not affect standard PCB footprint compatibility for axial through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD2K00 be used as a direct replacement for RNF14FAD2K00? A: Yes. Both parts are manufactured by Stackpole Electronics Inc with identical electrical specifications (2 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C). The only difference is packaging format (Cut Tape vs. Tape & Box). Electrical and thermal performance are equivalent.

Q: What are the advantages of using CMF552K0000BEEB or CMF552K0000BHEB over the original RNF14FAD2K00? A: These Vishay Dale substitutes offer tighter tolerance (±0.1% vs. ±1%), improved temperature coefficient (±25ppm/°C or ±50ppm/°C vs. ±100ppm/°C), higher power rating (0.5W vs. 0.25W), extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C), and moisture-resistant features. These enhancements provide greater precision and thermal margin for demanding applications.

Q: Are the physical dimension differences between Stackpole and Vishay Dale parts significant? A: No. The dimension difference (0.090" Dia x 0.240" L vs. 0.093" Dia x 0.250" L) is minimal and does not affect standard PCB footprint compatibility for axial through-hole resistor applications. Both maintain the same axial package type and lead spacing.

Q: Which substitute should I select for high-precision applications? A: CMF552K0000BEEB offers the tightest tolerance (±0.1%) and lowest temperature coefficient (±25ppm/°C), making it suitable for precision measurement and calibration circuits. CMF552K0000BHEB provides ±0.1% tolerance with ±50ppm/°C temperature coefficient as an alternative.

Q: Are all substitute parts ROHS3 compliant? A: Yes. RNF14FTD2K00, CMF552K0000BEEB, CMF552K0000BHEB, and CMF552K0000FHEB are all ROHS3 compliant with Active product status, matching the compliance profile of the original RNF14FAD2K00.

Q: Can CMF552K0000FHEB be used if I need ±1% tolerance matching the original specification? A: Yes. CMF552K0000FHEB maintains ±1% tolerance identical to RNF14FAD2K00 while providing increased power rating (0.5W), improved temperature coefficient (±50ppm/°C), extended operating temperature range, and moisture resistance.
