Key Parameters

Substitute Part Grouping Explanation

Substitution of the RNF12FTC200K is determined by strict equivalence across the following critical parameters:

• Resistance value: 200 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Metal Film
• Package: Axial through-hole
• Temperature coefficient: ±50ppm/°C
• Regulatory compliance: ROHS3 Compliant

The CMF55200K00FHEB from Vishay Dale meets all these criteria. While physical dimensions and operating temperature range differ slightly, the electrical performance and functional specifications remain equivalent for circuit-level substitution purposes.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC200K and CMF55200K00FHEB are Active products with ROHS3 compliance and REACH Unaffected status. Selection between these parts should be based on:

• Packaging requirements: RNF12FTC200K is supplied in Tape & Reel format; CMF55200K00FHEB is supplied in Cut Tape format
• Operating temperature envelope: CMF55200K00FHEB extends to 175°C versus 155°C for RNF12FTC200K
• Moisture resistance: CMF55200K00FHEB includes moisture resistant feature
• Physical dimensions: RNF12FTC200K measures 0.108" Dia x 0.344" L; CMF55200K00FHEB measures 0.090" Dia x 0.240" L
• Inventory availability and lead time considerations

Frequently Asked Questions (FAQ)

Q: Can CMF55200K00FHEB replace RNF12FTC200K in existing designs?

A: Yes, from an electrical standpoint. Both components share identical resistance (200 kOhms), tolerance (±1%), power rating (0.5W), composition (metal film), and temperature coefficient (±50ppm/°C). Physical dimensions differ, which may affect PCB layout and mechanical fit. Verify board space constraints before substitution.

Q: What is the difference in operating temperature range?

A: RNF12FTC200K operates from -55°C to 155°C. CMF55200K00FHEB operates from -55°C to 175°C. For applications requiring operation above 155°C, CMF55200K00FHEB provides extended thermal capability.

Q: Are packaging formats interchangeable?

A: No. RNF12FTC200K is supplied in Tape & Reel (TR) format for automated assembly. CMF55200K00FHEB is supplied in Cut Tape (CT) format. Packaging selection depends on assembly equipment and production volume requirements.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both RNF12FTC200K and CMF55200K00FHEB are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS code 8533.21.0090.

Q: What additional feature does CMF55200K00FHEB provide?

A: CMF55200K00FHEB includes moisture resistant coating in addition to flame retardant coating and safety features. This provides enhanced protection in humid or moisture-prone environments.
