RN55E1003FRE6 Equivalent & Substitute Parts

Part Overview

The RN55E1003FRE6 is a 100 kOhms ±1% metal film through-hole resistor rated at 0.125W (1/8W) in axial package configuration. Manufactured by Vishay Dale under the military-grade RN55 series (MIL-R-10509/7), this component features flame retardant coating, moisture resistance, and safety-rated construction suitable for military and high-reliability applications. The part maintains active product status with 1078 units in current inventory. Substitute parts may be required due to packaging availability, tolerance requirements, or inventory constraints in procurement workflows.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55E1003FRE6 is determined by the following critical parameters:

• Resistance Value: Must be 100 kOhms
• Power Rating: Must be 0.125W (1/8W) minimum
• Package Type: Must be Axial configuration
• Composition: Must be Metal Film
• Temperature Coefficient: Must be ±25ppm/°C
• Operating Temperature Range: Must support -65°C to 175°C
• Series Compliance: Must belong to RN55 military series (MIL-R-10509/7)
• Physical Dimensions: Must match 0.090" Dia x 0.240" L (2.29mm x 6.10mm)

The RN55E1003BRE6 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary difference is tolerance specification (±0.1% versus ±1%) and packaging format (Cut Tape versus Tape & Reel), both of which represent functional upgrades or alternative procurement formats rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55E1003FRE6 and RN55E1003BRE6 maintain active product status and identical compliance profiles (RoHS non-compliant, REACH Affected, ECCN EAR99). Selection between these parts should be based on:

RN55E1003FRE6 (Tape & Reel packaging): Suitable for high-volume automated assembly operations where reel-based component feeding is standard.

RN55E1003BRE6 (Cut Tape packaging): Suitable for lower-volume builds, manual assembly processes, or applications where individual component handling is preferred. The tighter ±0.1% tolerance provides enhanced precision for circuits requiring stricter resistance values.

Both parts satisfy military-grade specifications, moisture resistance requirements, and the full operating temperature range of -65°C to 175°C. Substitution is electrically and mechanically valid across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can RN55E1003BRE6 replace RN55E1003FRE6 in production?

A: Yes. Both parts are electrically and mechanically equivalent. The RN55E1003BRE6 features improved tolerance (±0.1% versus ±1%) and alternative packaging (Cut Tape versus Tape & Reel). Substitution is valid provided the assembly process accommodates Cut Tape format.

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

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place equipment. Cut Tape (CT) packaging provides components pre-cut from tape, typically used for manual assembly or lower-volume production runs.

Q: Does the tolerance difference affect circuit performance?

A: The RN55E1003BRE6 tolerance of ±0.1% is tighter than the RN55E1003FRE6 tolerance of ±1%. For circuits requiring precise resistance values, the substitute part provides superior tolerance performance. For applications with ±1% tolerance requirements, both parts are functionally equivalent.

Q: Are both parts compliant with military specifications?

A: Yes. Both parts conform to MIL-R-10509/7 military resistor specifications and belong to the RN55 series. Both maintain identical operating temperature ranges (-65°C to 175°C) and feature military-grade construction with flame retardant coating and moisture resistance.

Q: What are the physical dimensions, and are they identical?

A: Both parts share identical axial package dimensions of 0.090" diameter by 0.240" length (2.29mm x 6.10mm). Physical compatibility is confirmed for PCB layouts and mechanical assembly.
