RN55E2001CBSL Equivalent & Substitute Parts

Part Overview

The RN55E2001CBSL is a 2 kOhms ±0.25% metal film through-hole resistor rated at 0.125W (1/8W) in axial package configuration. This component is part of the Vishay Dale RN55 military-grade series, featuring flame retardant coating, moisture resistance, and safety certification per MIL-R-10509/7. The part is currently active in production with 1173 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, design optimization, or tolerance upgrades.

Key Parameters

Substitute Part Grouping Explanation

The RN55E2001BB14 qualifies as a direct substitute based on the following criteria:

Electrical compatibility is maintained through identical resistance value (2 kOhms) and power rating (0.125W). The substitute features an improved tolerance specification (±0.1% versus ±0.25%), which represents an upgrade in precision while remaining fully compatible with circuits designed for the original tolerance. Temperature coefficient (±25ppm/°C) and operating temperature range (-65°C to 175°C) are identical across both parts.

Mechanical compatibility is confirmed through identical package configuration (axial), physical dimensions (0.090" Dia x 0.240" L), and number of terminations (2). Both parts share the same military series designation (MIL-R-10509/7, RN55) and identical feature set (flame retardant coating, military grade, moisture resistant, safety certified).

Material composition (metal film) and manufacturing standards are consistent between the main part and substitute.

Parameter Comparison

Engineering Selection Recommendations

Both RN55E2001CBSL and RN55E2001BB14 are active production components from Vishay Dale with identical military certification (MIL-R-10509/7) and compliance status. Selection between these parts should be based on tolerance requirements for the specific application circuit.

The RN55E2001CBSL (±0.25% tolerance) is suitable for general-purpose military and industrial applications where standard precision is acceptable. The RN55E2001BB14 (±0.1% tolerance) provides enhanced precision and is appropriate for circuits requiring tighter resistance value control, such as precision measurement, filtering, or reference circuits.

Both parts maintain identical RoHS non-compliant status, REACH affected designation, and ECCN/HTSUS classifications. Thermal performance and environmental operating conditions are equivalent across both options.

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 be used as a direct replacement for RN55E2001CBSL?

A: Yes. The RN55E2001BB14 is electrically and mechanically compatible with RN55E2001CBSL.
