Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN55C2001CBSL is determined by strict equivalence in the following critical parameters:

• Resistance Value: Must be 2 kOhms (exact match required)
• Power Rating: Must be 0.125W (1/8W) minimum
• Package Configuration: Must be Axial through-hole
• Physical Dimensions: Must be 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Composition: Must be Metal Film
• Series Compliance: Must conform to MIL-R-10509/7 military specification
• Operating Temperature: Must support -65°C to 175°C range
• Termination Count: Must have 2 terminations

The RN55E2001BB14 qualifies as a direct substitute because it maintains all critical parameters while offering improved tolerance specification (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). Both parts share identical resistance, power rating, package type, dimensions, composition, military series designation, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C2001CBSL and RN55E2001BB14 are active production components manufactured by Vishay Dale with identical military series designation (MIL-R-10509/7, RN55) and compliance certifications. Selection between these parts depends on application-specific tolerance and stability requirements:

RN55C2001CBSL is appropriate for applications where ±0.25% tolerance and ±50ppm/°C temperature coefficient meet design specifications and cost optimization is prioritized.

RN55E2001BB14 is appropriate for applications requiring tighter tolerance control (±0.1%) and improved temperature stability (±25ppm/°C). This substitute provides enhanced performance characteristics while maintaining full compatibility with the original part's mechanical, electrical, and environmental specifications.

Both parts maintain identical RoHS non-compliant and REACH Affected status, with matching ECCN (EAR99) and HTSUS (8533.21.0090) classifications. Axial package configuration, physical dimensions, and operating temperature range (-65°C to 175°C) are identical across both parts, ensuring direct mechanical and thermal compatibility in circuit board layouts and thermal management designs.

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 be used as a direct replacement for RN55C2001CBSL?

A: Yes. Both parts share identical resistance value (2 kOhms), power rating (0.125W), package configuration (Axial), physical dimensions (0.090" Dia x 0.240" L), operating temperature range (-65°C to 175°C), and military series compliance (MIL-R-10509/7). The RN55E2001BB14 offers improved tolerance (±0.1% versus ±0.25%) and temperature coefficient (±25ppm/°C versus ±50ppm/°C) as performance enhancements.

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

A: The primary differences are tolerance specification and temperature coefficient. RN55C2001CBSL specifies ±0.25% tolerance with ±50ppm/°C temperature coefficient, while RN55E2001BB14 specifies ±0.1% tolerance with ±25ppm/°C temperature coefficient. All other electrical, mechanical, and environmental parameters are identical.

Q: Are there any package or footprint differences?

A: No. Both parts use identical Axial package configuration with matching physical dimensions of 0.090" Dia x 0.240" L (2.29mm x 6.10mm). They are mechanically interchangeable in through-hole circuit board designs.

Q: Do these parts have the same compliance certifications?

A: Yes. Both parts share identical RoHS non-compliant status, REACH Affected designation, ECCN classification (EAR99), and HTSUS code (8533.21.0090). Military series compliance (MIL-R-10509/7) and feature set (Flame Retardant Coating, Military, Moisture Resistant, Safety) are identical.

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

A: RN55E2001BB14 is appropriate for applications requiring tighter tolerance control and improved temperature stability. The ±0.1% tolerance and ±25ppm/°C temperature coefficient provide enhanced accuracy and predictability across the full operating temperature range.

Q: Are both parts currently available?

A: Yes. RN55C2001CBSL has 720 units in stock, and RN55E2001BB14 has 936 units in stock, both listed as new original inventory.
