Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN55D9091FRE6 is determined by equivalence across the following critical parameters:

• Resistance value: 9.09 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 175°C
• Package type: Axial
• Physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Termination count: 2
• Military series compliance: MIL-R-10509/7, RN55

The RN55D9091FB14 qualifies as a direct substitute based on identical electrical specifications and mechanical dimensions. The only difference is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Bulk packaging. Both parts maintain the same base product number (RN55) and comply with identical military and safety standards.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55D9091FRE6 and RN55D9091FB14 are active production parts manufactured by Vishay Dale with identical electrical and mechanical specifications. Selection between these parts is determined by packaging requirements and inventory availability.

The RN55D9091FRE6 in Tape & Reel format is suitable for automated assembly processes requiring continuous component feed. The RN55D9091FB14 in Bulk packaging is suitable for manual assembly, kit builds, or applications where tape packaging is not required.

Both parts comply with MIL-R-10509/7 military specification and maintain RoHS non-compliant status with REACH Affected designation. ECCN classification is EAR99 for both variants.

Frequently Asked Questions (FAQ)

Q: Can RN55D9091FB14 replace RN55D9091FRE6 in my circuit?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk versus Tape & Reel). Substitution is valid for any application where the RN55D9091FRE6 is specified, provided the bulk packaging format is compatible with your assembly process.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape suitable for automated pick-and-place assembly equipment. Bulk packaging supplies loose components suitable for manual assembly or kit applications. Electrical and mechanical performance are identical.

Q: Are both parts military-grade?

A: Yes. Both RN55D9091FRE6 and RN55D9091FB14 comply with military specification MIL-R-10509/7 and feature flame retardant coating, moisture resistance, and safety-rated construction.

Q: What is the operating temperature range?

A: Both parts operate from -65°C to 175°C with a temperature coefficient of ±100ppm/°C.

Q: Are these parts RoHS compliant?

A: No. Both parts are RoHS non-compliant but are REACH Affected with EAR99 ECCN classification.
