Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNX038200MFNEE is determined by the following critical parameters:

• Resistance Value: 200 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package Type: Axial (exact match required)
• Power Rating: Minimum 1W (equal or greater acceptable)
• Composition: Metal oxide film or thick film (both suitable for high-voltage applications)
• Operating Temperature Range: Minimum -55°C ~ 150°C coverage
• RoHS Compliance: ROHS3 or equivalent compliance required

Two active substitute parts meet these criteria: HTE52-200MF (Riedon) and HVLR1905F200MK9 (RESI). Both maintain the required 200 mOhms resistance, ±1% tolerance, and axial package configuration. The HTE52-200MF offers increased power rating (5W), while HVLR1905F200MK9 matches the original 1W specification.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing status, addressing the obsolescence of the RNX038200MFNEE. Selection between HTE52-200MF and HVLR1905F200MK9 depends on application-specific requirements:

HTE52-200MF (Riedon) is suitable for applications requiring enhanced thermal performance or higher power dissipation margins. The 5W rating provides additional headroom beyond the original 1W specification. Extended operating temperature range (-55°C ~ 195°C) accommodates higher ambient conditions. Thick film composition with flame-proof rating and non-inductive characteristics support high-voltage circuit applications. Physical dimensions are larger (8.00mm diameter x 52.00mm length), requiring PCB layout verification.

HVLR1905F200MK9 (RESI) maintains the original 1W power rating and provides closer dimensional compatibility (5.00mm diameter x 19.00mm length) compared to the RNX038200MFNEE. Operating temperature range (-55°C ~ 175°C) exceeds the original specification. Thick film composition with moisture-resistant and non-inductive features supports high-voltage applications. This option minimizes PCB redesign requirements for direct replacement scenarios.

Both parts satisfy ROHS3 compliance requirements and maintain the critical 200 mOhms ±1% electrical specification.

Frequently Asked Questions (FAQ)

Q: Can HTE52-200MF be used as a direct replacement for RNX038200MFNEE?

A: HTE52-200MF meets all critical electrical parameters (200 mOhms, ±1% tolerance, axial package). However, physical dimensions differ significantly (8.00mm x 52.00mm versus 4.66mm x 10.67mm). PCB layout verification is required to confirm mechanical fit within the available space.

Q: What is the difference between metal oxide film and thick film composition?

A: Both compositions are suitable for high-voltage applications. Metal oxide film (original) and thick film (substitutes) differ in manufacturing process and performance characteristics. Thick film substitutes offer improved temperature coefficient (±100ppm/°C versus ±200ppm/°C), resulting in better stability across temperature variations.

Q: Is HVLR1905F200MK9 a better choice for space-constrained applications?

A: HVLR1905F200MK9 dimensions (5.00mm x 19.00mm) are closer to the original RNX038200MFNEE (4.66mm x 10.67mm), making it more suitable for applications with limited PCB space. HTE52-200MF requires significantly more board area due to its larger physical footprint.

Q: Do both substitutes maintain RoHS compliance?

A: Yes. HTE52-200MF is ROHS3 compliant. HVLR1905F200MK9 is RoHS compliant. Both satisfy regulatory requirements for lead-free and restricted substance compliance.

Q: What is the impact of different operating temperature ranges?

A: RNX038200MFNEE operates -55°C ~ 150°C. HTE52-200MF extends to -55°C ~ 195°C, and HVLR1905F200MK9 to -55°C ~ 175°C. Both substitutes provide equal or superior temperature coverage, ensuring compatibility in applications operating within or below the original temperature specification.
