RN65D4702FRE6 Equivalent & Substitute Parts

Part Overview

The RN65D4702FRE6 is a 47 kOhms ±1% metal film axial through-hole resistor rated at 0.5W (1/2W) power dissipation. 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 1044 units in stock. Substitute parts may be required due to inventory constraints, packaging preferences, or application-specific power rating requirements while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RN65D4702FRE6 and RN70E4702FB14 are active production components from Vishay Dale with identical RoHS non-compliance status and REACH affected classification. The RN70E4702FB14 represents an upgrade path offering higher power dissipation capability (0.75W versus 0.5W) and superior temperature coefficient stability (±25ppm/°C versus ±100ppm/°C) while maintaining identical physical dimensions and electrical resistance specifications. Selection between these parts depends on application power requirements and packaging format availability. The RN70E4702FB14 is suitable for applications requiring enhanced thermal performance or higher power margins within the same footprint.

Frequently Asked Questions (FAQ)

Q: Can the RN70E4702FB14 directly replace the RN65D4702FRE6 in existing designs?

A: Yes. Both components share identical resistance (47 kOhms), tolerance (±1%), axial package configuration, physical dimensions (0.180" Dia x 0.562" L), operating temperature range (-65°C to 175°C), and feature set (Flame Retardant Coating, Military, Moisture Resistant, Safety). The RN70E4702FB14 provides higher power rating and improved temperature coefficient, making it functionally compatible for direct substitution.

Q: What are the key differences between these two resistors?

A: The primary differences are power rating (0.75W versus 0.5W), temperature coefficient (±25ppm/°C versus ±100ppm/°C), military specification tier (MIL-R-10509/3 versus MIL-R-10509/2), and packaging format (Bulk versus Tape & Reel). Electrical resistance and tolerance remain identical.

Q: Does the packaging format difference affect circuit board assembly?

A: Packaging format (Bulk versus Tape & Reel) affects procurement and handling procedures but does not impact electrical or mechanical performance once the component is installed on the circuit board. Both formats contain identical components with the same physical dimensions and electrical characteristics.

Q: Are both parts compliant with military specifications?

A: Both components comply with military standards. The RN65D4702FRE6 conforms to MIL-R-10509/2, while the RN70E4702FB14 conforms to the higher specification tier MIL-R-10509/3. Both are RoHS non-compliant and REACH affected.

Q: Which part should be selected for applications with higher power dissipation requirements?

A: The RN70E4702FB14 with its 0.75W power rating is suitable for applications requiring higher power dissipation margins compared to the 0.5W rating of the RN65D4702FRE6, provided the application circuit board layout and thermal management accommodate the component.
