RN60D3903FRE6 Equivalent & Substitute Parts

Part Overview

The RN60D3903FRE6 is a 390 kOhms ±1% metal film through-hole resistor rated at 0.25W (1/4W) in axial package configuration. Manufactured by Vishay Dale under the military-grade RN60 series (MIL-R-10509/1), this component features flame retardant coating, moisture resistance, and safety-rated construction suitable for military and high-reliability applications. The part is currently active in production with 1095 units in stock. Substitute parts may be required due to packaging availability, inventory constraints, or specific procurement requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The RN60D3903FB14 qualifies as a direct substitute for the RN60D3903FRE6 based on the following criteria:

Matching Electrical Parameters:

• Identical resistance value: 390 kOhms
• Identical tolerance: ±1%
• Identical power rating: 0.25W (1/4W)
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -65°C to 175°C

Matching Mechanical Parameters:

• Identical composition: Metal Film
• Identical package type: Axial
• Identical physical dimensions: 0.145" Dia x 0.344" L (3.68mm x 8.74mm)
• Identical series designation: RN60 (Military, MIL-R-10509/1)
• Identical features: Flame Retardant Coating, Military, Moisture Resistant, Safety

Difference: The sole distinction between these parts is packaging format: RN60D3903FRE6 is supplied in Tape & Reel (TR) configuration, while RN60D3903FB14 is supplied in Bulk packaging. Both parts maintain identical electrical performance and physical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both RN60D3903FRE6 and RN60D3903FB14 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements:

RN60D3903FRE6 (Tape & Reel): Suitable for automated assembly processes requiring tape-and-reel packaging format.

RN60D3903FB14 (Bulk): Suitable for manual assembly, kit builds, or applications where bulk packaging is acceptable.

Both parts comply with MIL-R-10509/1 military specifications and maintain identical performance across all electrical parameters, temperature ranges, and physical dimensions. Neither part is RoHS compliant; both are REACH Affected and classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can RN60D3903FB14 be used as a direct replacement for RN60D3903FRE6?
