RNF14BTC2K00 Equivalent & Substitute Parts

Part Overview

The RNF14BTC2K00 is a 2 kOhms ±0.1% metal film axial through-hole resistor rated at 0.25W (1/4W) manufactured by Stackpole Electronics Inc. This component features flame retardant coating and safety construction, designed for precision applications requiring tight tolerance specifications. The part is currently active in production with ROHS3 compliance and is suitable for applications where exact resistance values and low temperature coefficient performance are critical.

Substitute parts become necessary when the original component reaches end-of-life status, inventory constraints occur, or when design requirements allow for compatible alternatives that offer enhanced performance characteristics or improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14BTC2K00 are qualified based on the following critical parameters that determine functional equivalence:

Core Electrical Parameters (Must Match):

• Resistance value: 2 kOhms
• Tolerance: ±0.1%
• Composition: Metal Film
• Package type: Axial through-hole

Allowable Variations:

• Power rating may be equal or higher (0.25W or greater)
• Operating temperature range may be equal or extended
• Temperature coefficient may be equal or lower in absolute value
• Physical dimensions may vary within axial package constraints

The substitute parts CMF552K0000BEEB and CMF552K0000BHEB from Vishay Dale meet these criteria. Both maintain identical resistance, tolerance, and metal film composition while offering increased power dissipation capability (0.5W vs 0.25W) and extended maximum operating temperature (175°C vs 155°C). These upgrades provide enhanced performance margins without compromising the original design requirements.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified alternatives to the RNF14BTC2K00 based on electrical and mechanical compatibility. Selection between the three parts should be based on the following criteria:

RNF14BTC2K00 (Original): Select when the original part is available and design specifications do not require enhanced performance margins. Maintains exact original specifications with proven field history.

CMF552K0000BEEB: Select when improved temperature coefficient performance (±25ppm/°C vs ±50ppm/°C) is beneficial for precision applications operating across wide temperature ranges. Offers higher power dissipation capability and extended operating temperature to 175°C. ROHS3 compliant with moisture-resistant construction.

CMF552K0000BHEB: Select when maintaining the original temperature coefficient (±50ppm/°C) is required while gaining the benefits of higher power rating (0.5W) and extended operating temperature range (175°C). ROHS3 compliant with moisture-resistant construction. Highest inventory availability among substitute options.

All three parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can CMF552K0000BEEB or CMF552K0000BHEB be used as direct replacements for RNF14BTC2K00?

A: Yes. Both Vishay Dale parts are electrically and mechanically compatible. They maintain identical resistance (2 kOhms) and tolerance (±0.1%) specifications. The higher power rating (0.5W vs 0.25W) and extended operating temperature range (175°C vs 155°C) represent performance upgrades that do not compromise the original design.

Q: What is the difference between CMF552K0000BEEB and CMF552K0000BHEB?

A: The primary difference is temperature coefficient. CMF552K0000BEEB has ±25ppm/°C while CMF552K0000BHEB has ±50ppm/°C (matching the original RNF14BTC2K00). Both share identical resistance, tolerance, power rating, and operating temperature range. Selection depends on whether improved temperature stability is required for the application.

Q: Are there physical dimension differences between these parts?

A: The RNF14BTC2K00 measures 0.093" Dia x 0.250" L (2.35mm x 6.35mm). Both Vishay Dale substitutes measure 0.090" Dia x 0.240" L (2.29mm x 6.10mm). These minor dimensional variations are within acceptable tolerances for standard axial through-hole mounting and do not affect PCB layout compatibility.

Q: Do the substitute parts have additional features?

A: Yes. Both CMF552K0000BEEB and CMF552K0000BHEB include moisture-resistant construction in addition to the flame retardant coating and safety features present in the original RNF14BTC2K00. This provides enhanced environmental protection without affecting electrical performance.

Q: Are all three parts ROHS3 compliant?

A: Yes. The RNF14BTC2K00, CMF552K0000BEEB, and CMF552K0000BHEB are all ROHS3 compliant and REACH unaffected, ensuring regulatory compatibility for applications subject to these standards.

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

A: Both substitute parts support operating temperatures to 175°C, compared to 155°C for the original. For applications requiring the best temperature stability across this extended range, CMF552K0000BEEB with ±25ppm/°C temperature coefficient is preferred. For applications where the original ±50ppm/°C specification is acceptable, CMF552K0000BHEB offers equivalent performance with higher inventory availability.
