RN65E5003FRE6 Equivalent & Substitute Parts

Part Overview

The RN65E5003FRE6 is a 500 kOhms ±1% metal film through-hole resistor rated at 0.5W (1/2W) in axial package configuration. Manufactured by Vishay Dale under the military-grade RN65 series (MIL-R-10509/2), 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 659 units available in tape & reel packaging.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the allowed parameter range for this resistor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN65E5003FRE6 is determined by the following critical parameters:

• Resistance Value: Must be 500 kOhms
• Power Rating: Must be 0.5W (1/2W)
• Package Type: Must be Axial
• Physical Dimensions: Must be 0.180" Dia x 0.562" L (4.57mm x 14.27mm)
• 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-10509/2 RN65 series

Tolerance and packaging format (tape & reel vs. bulk) are secondary parameters that do not prevent substitution when all primary electrical and mechanical specifications are met. The RN65E5003FB14 and RN65E5003BB14 satisfy all critical substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

RN65E5003FB14 (Direct Substitute)

The RN65E5003FB14 provides direct electrical and mechanical equivalence to the RN65E5003FRE6. Both parts maintain identical resistance, tolerance, power rating, temperature coefficient, and operating range. The primary difference is packaging format: bulk versus tape & reel. This substitute is suitable for applications where packaging format does not impose procurement or assembly constraints. Inventory availability is 1206 units.

RN65E5003BB14 (Upgrade Substitute)

The RN65E5003BB14 offers enhanced tolerance performance at ±0.1% compared to the ±1% specification of the main part, while maintaining all other electrical and mechanical parameters. This upgrade substitute is applicable in precision circuit designs where tighter tolerance requirements improve overall circuit performance or reduce calibration requirements. All compliance certifications (MIL-R-10509/2, REACH, ECCN EAR99) remain equivalent. Inventory availability is 1650 units.

Both substitute parts are manufactured by Vishay Dale under the same military RN65 series and maintain active production status.

Frequently Asked Questions (FAQ)

Q: Can RN65E5003FB14 be used as a direct replacement for RN65E5003FRE6?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 500 kOhms resistance, ±1% tolerance, 0.5W power rating, axial package, and identical physical dimensions. The difference is packaging format (bulk vs. tape & reel), which does not affect component performance.

Q: What is the advantage of using RN65E5003BB14 instead of the original part?

A: The RN65E5003BB14 provides ±0.1% tolerance versus ±1% on the original part. This tighter tolerance reduces resistance variation and is beneficial in precision analog circuits, measurement equipment, or applications where component tolerance stack-up affects system accuracy.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts share identical axial package configuration and physical dimensions (0.180" Dia x 0.562" L). They are mechanically interchangeable on the same PCB layout.

Q: Do packaging format differences affect circuit performance?

A: No. Tape & reel and bulk packaging formats contain identical components. The packaging format affects only procurement, storage, and assembly handling. Electrical and mechanical performance is unchanged.

Q: Are these parts suitable for military applications?

A: Yes. All three parts comply with MIL-R-10509/2 military specification and are manufactured as military-grade components with flame retardant coating and moisture resistance. Product status is active for all parts.

Q: What is the temperature stability of these resistors?

A: All three parts maintain a temperature coefficient of ±25ppm/°C across the operating range of -65°C to 175°C, ensuring stable resistance performance across military and industrial temperature extremes.
