Substitute Part Grouping Explanation

The RN55E2001BB14 qualifies as a direct substitute for the RN55C2001FRE6 based on the following critical parameters:

• Resistance Value: Both parts are 2 kOhms
• Power Rating: Both rated at 0.125W (1/8W)
• Composition: Both are metal film construction
• Package Type: Both use axial through-hole configuration
• Physical Dimensions: Identical at 0.090" Dia x 6.10mm L
• Operating Temperature Range: Both operate from -65°C to 175°C
• Series Classification: Both belong to the military RN55 series per MIL-R-10509/7
• Features: Both include flame retardant coating, military grade, moisture resistance, and safety certifications

The RN55E2001BB14 provides enhanced tolerance (±0.1% versus ±1%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring tighter specifications while maintaining full compatibility with the original part's electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C2001FRE6 and RN55E2001BB14 are active production components from Vishay Dale with identical military certifications and compliance status. Selection between these parts depends on application tolerance and stability requirements:

• RN55C2001FRE6: Select for applications where ±1% tolerance and ±50ppm/°C temperature coefficient meet design specifications and cost optimization is prioritized.
• RN55E2001BB14: Select for precision applications requiring tighter tolerance control (±0.1%) and improved temperature stability (±25ppm/°C) while maintaining full mechanical and electrical compatibility.

Both parts maintain RoHS non-compliant and REACH Affected status, requiring equivalent compliance documentation for procurement and supply chain management.

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 directly replace RN55C2001FRE6 in existing designs?

A: Yes. Both parts share identical resistance value (2 kOhms), power rating (0.125W), physical dimensions (0.090" Dia x 0.240" L), operating temperature range (-65°C to 175°C), and axial package configuration. The RN55E2001BB14 provides enhanced specifications without compromising mechanical or electrical compatibility.

Q: What are the key differences between these parts?

A: The primary differences are tolerance and temperature coefficient. RN55C2001FRE6 offers ±1% tolerance with ±50ppm/°C temperature coefficient, while RN55E2001BB14 provides ±0.1% tolerance with ±25ppm/°C temperature coefficient. Both maintain identical military-grade construction and certifications.

Q: Are there packaging differences between these parts?

A: Yes. RN55C2001FRE6 is supplied in Cut Tape (CT) packaging, while RN55E2001BB14 is supplied in Bulk packaging. Both use identical axial through-hole configuration with the same physical dimensions, so they are mechanically interchangeable on PCBs.

Q: Do both parts meet the same military specifications?

A: Yes. Both parts comply with MIL-R-10509/7 and belong to the military RN55 series. Both include flame retardant coating, moisture resistance, and safety features required for military applications.

Q: What compliance considerations apply to both parts?

A: Both parts are RoHS non-compliant and REACH Affected. Equivalent compliance documentation and supply chain verification are required for procurement in regulated environments.
