Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14BTC200K are qualified based on the following criteria:

Electrical Equivalence:

• Identical resistance value: 200 kOhms
• Matching tolerance: ±0.1%
• Metal film composition maintained
• Axial package configuration

Mechanical Compatibility:

• Through-hole axial form factor
• Physical dimensions compatible with standard PCB layouts
• Two terminations (standard axial lead configuration)

Environmental & Compliance:

• ROHS3 compliance maintained
• Flame retardant coating present
• Safety-rated construction
• Operating temperature range sufficient for application (-55°C minimum)

The substitute parts CMF55200K00BEEB and CMF55200K00BHEB are qualified as upgrades due to higher power ratings (0.5W vs. 0.25W) and extended maximum operating temperature (175°C vs. 155°C), while maintaining all critical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both CMF55200K00BEEB and CMF55200K00BHEB are active production parts with ROHS3 compliance and full regulatory alignment. Selection between these substitutes and the original RNF14BTC200K depends on application requirements:

Use RNF14BTC200K when:

• Original equipment specification requires Stackpole Electronics manufacture
• Packaging format must be Tape & Reel (TR)
• Power dissipation is strictly limited to 0.25W maximum

Use CMF55200K00BEEB when:

• Higher power dissipation capability (0.5W) is beneficial
• Lower temperature coefficient (±25ppm/°C) improves stability
• Extended operating temperature to 175°C is required
• Moisture resistance feature is advantageous

Use CMF55200K00BHEB when:

• Higher power dissipation capability (0.5W) is beneficial
• Extended operating temperature to 175°C is required
• Moisture resistance feature is advantageous
• Temperature coefficient matching original specification (±50ppm/°C) is preferred

All three parts maintain identical electrical performance at 200 kOhms ±0.1% and are mechanically compatible in standard axial through-hole PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can CMF55200K00BEEB and CMF55200K00BHEB be used as direct replacements for RNF14BTC200K?

A: Yes. Both Vishay Dale parts maintain the critical electrical specifications: 200 kOhms resistance, ±0.1% tolerance, metal film composition, and axial package configuration. Physical dimensions are compatible with standard PCB layouts designed for axial resistors.

Q: What is the difference between CMF55200K00BEEB and CMF55200K00BHEB?

A: The primary difference is temperature coefficient. CMF55200K00BEEB has ±25ppm/°C while CMF55200K00BHEB has ±50ppm/°C (matching the original RNF14BTC200K). Both share identical power rating (0.5W), operating temperature range (-55°C to 175°C), and physical dimensions.

Q: Are there packaging differences between these parts?

A: Yes. The RNF14BTC200K is supplied in Tape & Reel (TR) packaging, while both Vishay Dale substitutes are supplied in Cut Tape (CT) packaging. This affects handling and assembly processes but does not impact electrical or mechanical compatibility.

Q: Do all three parts meet the same compliance standards?

A: Yes. RNF14BTC200K, CMF55200K00BEEB, and CMF55200K00BHEB are all ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What are the physical dimension differences?

A: RNF14BTC200K measures 0.093" diameter × 0.250" length (2.35mm × 6.35mm). Both Vishay Dale substitutes measure 0.090" diameter × 0.240" length (2.29mm × 6.10mm). These minor differences are within standard PCB layout tolerances for axial through-hole components.

Q: Can I use a 0.5W rated resistor in a circuit designed for 0.25W?

A: Yes. A higher power-rated component is electrically compatible and will operate safely in applications designed for lower power dissipation. The 0.5W rating provides additional thermal margin.
