Substitute Part Grouping Explanation

The RN55E2001BB14 qualifies as a direct substitute for the RN55C2001BBSL based on the following critical parameters:

• Identical resistance value: 2 kOhms
• Identical tolerance: ±0.1%
• Identical power rating: 0.125W (1/8W)
• Identical composition: Metal Film
• Identical package: Axial
• Identical operating temperature range: -65°C to 175°C
• Identical series classification: Military, MIL-R-10509/7, RN55
• Identical physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Identical termination count: 2
• Identical feature set: Flame Retardant Coating, Military, Moisture Resistant, Safety

The primary difference is the temperature coefficient specification, where RN55E2001BB14 provides improved stability at ±25ppm/°C compared to the RN55C2001BBSL at ±50ppm/°C. This represents an upgrade in thermal performance characteristics.

Both components are RoHS non-compliant and REACH-affected, with identical compliance classifications. Inventory availability favors RN55E2001BB14 with 936 units in stock compared to 854 units for the primary part.

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 be used as a direct replacement for RN55C2001BBSL?

A: Yes. Both components share identical electrical specifications (2 kOhms ±0.1%, 0.125W), physical dimensions (0.090" Dia x 0.240" L), package type (Axial), and operating temperature range (-65°C to 175°C). The RN55E2001BB14 provides improved temperature coefficient performance.

Q: What is the difference between these two parts?

A: The primary difference is the temperature coefficient specification. RN55C2001BBSL operates at ±50ppm/°C, while RN55E2001BB14 operates at ±25ppm/°C. This means RN55E2001BB14 exhibits lower resistance drift across the operating temperature range.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.090" diameter by 0.240" length (2.29mm x 6.10mm) in axial configuration, ensuring identical PCB footprint and mounting compatibility.

Q: Do both parts meet military specifications?

A: Yes. Both components are classified as Military series parts conforming to MIL-R-10509/7 standard with identical feature sets including flame retardant coating, moisture resistance, and safety characteristics.

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

A: RN55E2001BB14 is the appropriate selection for applications requiring minimal thermal drift, as its ±25ppm/°C temperature coefficient provides superior stability compared to the ±50ppm/°C specification of RN55C2001BBSL.
