Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C2001DB14 is determined by the following critical parameters:

• Resistance Value: Must be 2 kOhms (exact match required)
• Power Rating: Must be 0.125W (1/8W) minimum
• Package Type: Must be Axial configuration
• Composition: Must be Metal Film
• Series Compliance: Must belong to RN55 military series (MIL-R-10509/7)
• Operating Temperature Range: Must support -65°C to 175°C
• Physical Dimensions: Must match 0.090" Dia x 0.240" L (2.29mm x 6.10mm)

The RN55E2001BB14 qualifies as a direct substitute because it maintains all critical parameters while offering improved tolerance (±0.1% versus ±0.5%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both RN55C2001DB14 and RN55E2001BB14 are active production components with identical compliance profiles (RoHS non-compliant, REACH Affected, EAR99 classification). Selection between these parts should be based on tolerance and temperature coefficient requirements:

• RN55C2001DB14: Select when ±0.5% tolerance and ±50ppm/°C temperature coefficient meet circuit specifications and cost optimization is prioritized.
• RN55E2001BB14: Select when improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C) are required for precision applications or when tighter component matching is necessary across temperature variations.

Both parts maintain identical military-grade construction, flame retardant coating, moisture resistance, and safety features within the -65°C to 175°C operating range.

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 be used as a direct replacement for RN55C2001DB14?

A: Yes. Both parts share identical resistance value (2 kOhms), power rating (0.125W), package type (Axial), physical dimensions, and operating temperature range. The RN55E2001BB14 offers superior tolerance and temperature stability.

Q: What are the key differences between these two parts?
