Substitute Part Grouping Explanation

Substitution of the RNF14DTC200R is permissible with the CMF55200R00BHEB based on the following criteria:

Matching Parameters:

• Resistance value: 200 Ohms (identical)
• Package type: Axial through-hole (identical)
• Composition: Metal Film (identical)
• Temperature coefficient: ±50ppm/°C (identical)
• RoHS compliance: ROHS3 Compliant (identical)
• Regulatory status: REACH Unaffected, EAR99 classification (identical)

Enhanced Parameters in Substitute:

• Tolerance: ±0.1% (tighter than ±0.5%)
• Power rating: 0.5W (1/2W) (higher than 0.25W)
• Operating temperature range: -55°C to 175°C (extended upper limit)
• Additional feature: Moisture resistant coating

The substitute part meets or exceeds all critical electrical and mechanical specifications of the main part while maintaining axial package compatibility.

Parameter Comparison

Engineering Selection Recommendations

Selection between the RNF14DTC200R and CMF55200R00BHEB is determined by application requirements and supply availability:

Use RNF14DTC200R when:

• Tape & Reel packaging is required for automated assembly processes
• The 0.25W power rating is sufficient for the circuit design
• Operating temperature does not exceed 155°C
• ±0.5% tolerance meets circuit specifications

Use CMF55200R00BHEB when:

• Cut Tape packaging is acceptable or preferred
• Higher power dissipation capability (0.5W) provides design margin
• Operating temperature may reach up to 175°C
• Tighter tolerance (±0.1%) improves circuit accuracy
• Moisture resistance is beneficial for the application environment
• Supply chain availability favors this manufacturer

Both parts maintain identical RoHS3 compliance and regulatory certifications (REACH Unaffected, EAR99 classification), ensuring equivalent compliance status in regulated applications.

Frequently Asked Questions (FAQ)

Q: Can CMF55200R00BHEB directly replace RNF14DTC200R in existing designs?

A: Yes. Both parts share identical resistance (200 Ohms), tolerance capability (CMF55 is tighter at ±0.1%), axial package configuration, and temperature coefficient (±50ppm/°C). The substitute has higher power rating (0.5W vs 0.25W) and extended temperature range (-55°C to 175°C vs -55°C to 155°C), making it functionally compatible in all applications where the main part operates.

Q: What is the difference in physical dimensions?

A: RNF14DTC200R measures 0.093" diameter × 0.250" length (2.35mm × 6.35mm). CMF55200R00BHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). Both are axial through-hole components with 2 terminations. The slight dimensional difference does not affect PCB layout compatibility for standard axial resistor footprints.

Q: Are there packaging differences between these parts?

A: Yes. RNF14DTC200R is supplied in Tape & Reel (TR) format, suitable for pick-and-place assembly. CMF55200R00BHEB is supplied in Cut Tape (CT) format. Selection depends on assembly method: automated assembly typically requires Tape & Reel, while manual or semi-automated assembly may use Cut Tape.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RNF14DTC200R and CMF55200R00BHEB are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. They are equivalent in regulatory and environmental compliance status.

Q: What is the tolerance difference and does it matter?

A: RNF14DTC200R has ±0.5% tolerance while CMF55200R00BHEB has ±0.1% tolerance. The substitute provides tighter tolerance, which improves circuit accuracy. For applications where ±0.5% tolerance is specified as a requirement, both parts satisfy the specification. For precision circuits, the ±0.1% tolerance of the substitute offers better performance.
