RN55E2002FBSL Equivalent & Substitute Parts

Part Overview

The RN55E2002FBSL is a 20 kOhms ±1% 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 resistor series, designed for applications requiring flame retardant coating, moisture resistance, and safety compliance. The part is currently active in production with 909 units in stock. Substitute parts are identified to address inventory availability, packaging format requirements, or tolerance specifications while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55E2002FBSL is determined by the following critical parameters:

• Resistance Value: Must be 20 kOhms
• Power Rating: Must be 0.125W (1/8W)
• Package Type: Must be Axial
• Physical Dimensions: Must be 0.090" Dia × 0.240" L (2.29mm × 6.10mm)
• Composition: Must be Metal Film
• Temperature Coefficient: Must be ±25ppm/°C
• Operating Temperature Range: Must be -65°C to 175°C
• Series Compliance: Must be MIL-R-10509/7, RN55 military series
• Features: Must include Flame Retardant Coating, Military, Moisture Resistant, Safety

Tolerance specifications (±1% or ±0.1%) and packaging formats (Bulk or Cut Tape) are secondary parameters that do not prevent substitution but may affect application suitability and procurement logistics.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RN55E2002FBSL, RN55E2002BB14, and RN55E2002BRE6—are electrically and mechanically interchangeable for applications requiring a 20 kOhms ±1% metal film axial resistor in the RN55 military series. All parts maintain identical operating temperature ranges, physical dimensions, and military-grade specifications.

The RN55E2002BB14 and RN55E2002BRE6 offer improved tolerance specifications (±0.1% versus ±1%), which provides tighter resistance accuracy for precision circuit applications. These parts are suitable for direct substitution where tolerance enhancement is acceptable or beneficial.

Packaging format differences exist between the parts: RN55E2002FBSL and RN55E2002BB14 are supplied in Bulk format, while RN55E2002BRE6 is supplied in Cut Tape (CT) format. Selection between these formats depends on assembly process requirements and procurement logistics.

All parts share identical compliance status: RoHS non-compliant and REACH Affected. No compliance advantage exists between the three options.

Frequently Asked Questions (FAQ)

Q: Can RN55E2002BB14 or RN55E2002BRE6 be used as direct replacements for RN55E2002FBSL?

A: Yes. Both parts are electrically and mechanically compatible. They maintain the same 20 kOhms resistance value, 0.125W power rating, axial package configuration, and physical dimensions. The improved ±0.1% tolerance in the substitute parts provides tighter resistance accuracy without affecting circuit compatibility.

Q: What is the difference between Bulk and Cut Tape (CT) packaging?

A: Bulk packaging supplies loose components, while Cut Tape (CT) packaging provides components on carrier tape suitable for automated assembly equipment. Selection depends on manufacturing process requirements. Both packaging formats contain identical electrical components.

Q: Are there any compliance differences between these parts?

A: No. All three parts share identical RoHS and REACH compliance status. All are RoHS non-compliant and REACH Affected. No compliance advantage exists between the options.

Q: Does the improved tolerance of RN55E2002BB14 and RN55E2002BRE6 affect circuit performance?

A: The ±0.1% tolerance provides tighter resistance accuracy compared to the ±1% tolerance of RN55E2002FBSL. This improvement is beneficial for precision applications but does not create incompatibility with circuits designed for ±1% tolerance.

Q: What inventory considerations apply to these parts?

A: RN55E2002BRE6 has the highest inventory availability at 3902 units, followed by RN55E2002BB14 at 1118 units, and RN55E2002FBSL at 909 units. Inventory levels may influence procurement decisions based on project timelines and volume requirements.
