Parameter Comparison

Engineering Selection Recommendations

Both RN55C2001DR36 and RN55E2001BB14 maintain active product status and identical compliance classifications (RoHS non-compliant, REACH Affected). Selection between these parts depends on application-specific requirements:

Select RN55C2001DR36 when:

• Tape & Reel packaging is required for automated assembly processes
• Standard ±0.5% tolerance meets circuit specifications
• Temperature coefficient of ±50ppm/°C is acceptable for the application

Select RN55E2001BB14 when:

• Tighter tolerance of ±0.1% is required for precision circuit applications
• Lower temperature coefficient of ±25ppm/°C improves stability across the operating range
• Bulk packaging is compatible with assembly methodology
• Enhanced performance characteristics justify substitution

Both parts comply with MIL-R-10509/7 military specification and maintain identical electrical ratings, physical dimensions, and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 directly replace RN55C2001DR36 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 substitute offers improved tolerance (±0.1% vs ±0.5%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it functionally compatible and performance-enhanced.

Q: What is the primary difference between these two parts?

A: The main differences are packaging format (Tape & Reel vs Bulk) and electrical performance specifications. RN55E2001BB14 provides tighter tolerance and lower temperature coefficient, while RN55C2001DR36 is supplied in automated assembly-ready Tape & Reel format.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS non-compliant and REACH Affected status. Both comply with MIL-R-10509/7 military specification and share identical feature sets including flame retardant coating, military rating, moisture resistance, and safety construction.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel vs Bulk) does not affect electrical characteristics, performance, or reliability. The difference is purely in delivery and handling format for manufacturing processes.

Q: Which part should be selected for high-precision applications?

A: RN55E2001BB14 is suitable for applications requiring tighter tolerance control and improved temperature stability due to its ±0.1% tolerance and ±25ppm/°C temperature coefficient compared to the main part's ±0.5% tolerance and ±50ppm/°C coefficient.
