Substitute Part Grouping Explanation

Substitution eligibility for the RN55D1003FRE6 is determined by the following criteria:

• Resistance Value: Must be 100 kOhms
• Power Rating: Must be 0.125W (1/8W) or higher
• Package Configuration: Must be Axial with identical physical dimensions (0.090" Dia x 0.240" L)
• Composition: Must be Metal Film
• Series Compliance: Must belong to the RN55 military series with MIL-R-10509/7 certification
• Operating Temperature: Must support -65°C to 175°C range
• Features: Must include Flame Retardant Coating, Moisture Resistance, and Safety certification

The RN55E1003BRE6 qualifies as a direct substitute because it maintains all core electrical and mechanical parameters while offering improved tolerance specification (±0.1% versus ±1%) and superior temperature coefficient performance (±25ppm/°C versus ±100ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the RN55D1003FRE6 and RN55E1003BRE6 are active production components from Vishay Dale with identical military certification, compliance status, and regulatory classification. Selection between these parts should be based on application-specific tolerance and stability requirements. The RN55E1003BRE6 offers superior tolerance (±0.1%) and temperature coefficient performance (±25ppm/°C), making it suitable for precision circuit applications requiring tighter component matching. The RN55D1003FRE6 remains appropriate for general-purpose military applications where ±1% tolerance is acceptable. Both parts maintain identical RoHS non-compliant and REACH Affected status, requiring equivalent supply chain documentation and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can RN55E1003BRE6 be used as a direct replacement for RN55D1003FRE6?
