Key Parameters

Substitute Part Grouping Explanation

Substitution of the RNX050200MFNEE is determined by the following critical parameters:

• Resistance Value: 200 MOhms (exact match required)
• Tolerance: ±1% (maintains circuit accuracy specifications)
• Package Configuration: Axial through-hole (ensures mechanical and electrical compatibility)
• Voltage Rating Capability: High-voltage rated construction
• Safety Certification: Flame-proof and safety-rated features
• Compliance: ROHS3 compliance maintained

The HTE52-200MF qualifies as a substitute based on matching resistance, tolerance, axial package, high-voltage capability, and safety features across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The HTE52-200MF from Riedon serves as a direct functional substitute for the obsolete RNX050200MFNEE. Both components maintain identical resistance values and tolerance specifications, ensuring circuit performance equivalence. The substitute part is currently in active production status, providing supply continuity for applications requiring 200 MOhms ±1% axial resistors.

Key considerations for selection:

• Both parts maintain ROHS3 compliance and safety certifications
• The HTE52-200MF offers higher power dissipation capability (5W versus 1.2W), providing design margin in thermal management
• The substitute exhibits superior temperature coefficient performance (±100ppm/°C versus ±200ppm/°C), improving long-term stability
• Operating temperature range of the substitute extends to 195°C, which covers the majority of high-voltage applications; applications requiring operation above 195°C require thermal analysis
• Both components feature axial through-hole packaging, maintaining mechanical compatibility with existing PCB layouts

Frequently Asked Questions (FAQ)

Q: Can the HTE52-200MF directly replace the RNX050200MFNEE in existing designs?

A: Yes. Both components share identical resistance values (200 MOhms), tolerance (±1%), and axial package configuration. Electrical and mechanical compatibility is maintained. The substitute's higher power rating and improved temperature coefficient provide additional design margin.

Q: What is the impact of the different power ratings (1.2W versus 5W)?

A: The HTE52-200MF's higher power rating indicates greater thermal dissipation capability. In applications where the original 1.2W rating was adequate, the 5W substitute will operate at lower junction temperatures, extending component life and improving reliability.

Q: Are there temperature range limitations with the substitute?

A: The HTE52-200MF operates from -55°C to 195°C, compared to the original part's -55°C to 225°C range. Applications requiring sustained operation above 195°C require thermal analysis to confirm the substitute's suitability.

Q: How do the different film compositions affect performance?

A: The original uses metal oxide film construction while the substitute uses thick film. Both achieve ±1% tolerance and high-voltage ratings. The substitute's thick film composition provides non-inductive characteristics and moisture resistance, beneficial for high-frequency and humid environments.

Q: Are both parts RoHS compliant?

A: Yes. Both the RNX050200MFNEE and HTE52-200MF are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.
