RN65D4703FRE6 Equivalent & Substitute Parts

Part Overview

The RN65D4703FRE6 is a 470 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 certification suitable for military and high-reliability applications. The part is currently active in production with 1138 units in stock. Equivalent and substitute parts may be required due to packaging availability, inventory constraints, or application-specific power rating requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the RN65D4703FRE6 is determined by the following critical parameters: resistance value (470 kOhms), tolerance (±1%), composition (metal film), package type (axial), operating temperature range (-65°C to 175°C), and military-grade specifications. The packaging format (Tape & Reel versus Bulk) does not affect electrical or mechanical compatibility and permits direct substitution. The RN65D4703FB14 is a direct equivalent with identical electrical specifications and differs only in packaging format. The RN70E4703FB14 represents an upgrade option with increased power rating (0.75W versus 0.5W) and improved temperature coefficient (±25ppm/°C versus ±100ppm/°C), maintaining all other critical parameters including resistance, tolerance, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The RN65D4703FB14 provides direct electrical and mechanical compatibility with the RN65D4703FRE6, with the sole difference being packaging format (Bulk versus Tape & Reel). Both parts maintain identical resistance, tolerance, power rating, and temperature specifications. Selection between these two is determined by procurement and assembly requirements rather than technical performance.

The RN70E4703FB14 is suitable for applications requiring enhanced performance characteristics. The increased power rating (0.75W versus 0.5W) provides additional thermal margin in circuits operating near the 0.5W limit. The improved temperature coefficient (±25ppm/°C versus ±100ppm/°C) delivers superior frequency stability and reduced drift over the operating temperature range. All three parts maintain active production status and comply with military specifications (MIL-R-10509 series). Selection of the RN70E4703FB14 is appropriate when circuit design permits the use of higher-rated components or when improved temperature stability is a design requirement.

Frequently Asked Questions (FAQ)

Q: Can RN65D4703FB14 be used as a direct replacement for RN65D4703FRE6?

A: Yes. The RN65D4703FB14 is electrically and mechanically identical to the RN65D4703FRE6. The only difference is packaging format: RN65D4703FRE6 is supplied in Tape & Reel format while RN65D4703FB14 is supplied in Bulk format. Both parts are from the same RN65 military series with identical electrical specifications.

Q: What are the differences between RN65D4703FB14 and RN70E4703FB14?

A: Both parts maintain the same 470 kOhms resistance and ±1% tolerance. The RN70E4703FB14 differs in two specifications: power rating increases from 0.5W to 0.75W, and temperature coefficient improves from ±100ppm/°C to ±25ppm/°C. The RN70E4703FB14 belongs to the RN70 military series (MIL-R-10509/3) versus the RN65 series (MIL-R-10509/2).

Q: Is the RN70E4703FB14 a direct replacement for RN65D4703FRE6?

A: The RN70E4703FB14 is mechanically and electrically compatible for most applications. It can be substituted when the circuit design permits use of a higher power-rated component. The improved temperature coefficient may provide performance benefits in temperature-sensitive applications. Verify that the increased power rating does not introduce unintended thermal effects in the specific circuit application.

Q: Are all three parts RoHS compliant?

A: No. All three parts (RN65D4703FRE6, RN65D4703FB14, and RN70E4703FB14) are RoHS non-compliant. All three parts are REACH Affected and classified under ECCN EAR99.

Q: What is the significance of the packaging format difference?

A: Packaging format (Tape & Reel versus Bulk) affects procurement, storage, and assembly processes but does not impact electrical performance or mechanical fit. Tape & Reel format is optimized for automated assembly lines, while Bulk format is suitable for manual assembly or smaller production runs. Selection depends on manufacturing process requirements.

Q: Can these parts be used interchangeably in military applications?

A: Yes, within the constraints of their respective military specifications. RN65D4703FRE6 and RN65D4703FB14 are both qualified to MIL-R-10509/2. The RN70E4703FB14 is qualified to MIL-R-10509/3. Verify that the specific military application permits substitution between MIL-R-10509/2 and MIL-R-10509/3 specifications before implementation.
