RN65D4701FRE6 Equivalent & Substitute Parts

Part Overview

The RN65D4701FRE6 is a 4.7 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 per MIL-R-10509/2 specification, 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 798 units in stock. Substitute parts are identified to address packaging format availability, inventory constraints, or temperature coefficient performance requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN65D4701FRE6 is determined by strict equivalence across the following critical parameters:

• Electrical Parameters: Resistance value (4.7 kOhms), tolerance (±1%), and power rating (0.5W) must be identical
• Physical Parameters: Package type (Axial), size/dimension (0.180" Dia x 0.562" L), and number of terminations (2) must match
• Material & Construction: Metal film composition, flame retardant coating, military-grade construction, and moisture resistance must be maintained
• Operating Specifications: Temperature range (-65°C to 175°C) must be supported
• Series Compliance: All substitutes must belong to the RN65 military series per MIL-R-10509/2

Packaging format (Tape & Reel vs. Bulk) and temperature coefficient variations are permitted substitution parameters, as these do not affect electrical performance or mechanical fit in the target application.

Parameter Comparison

Engineering Selection Recommendations

RN65D4701FB14 (Direct Substitute): This part is electrically and mechanically identical to the RN65D4701FRE6, with the primary difference being packaging format (Bulk vs. Tape & Reel). Selection is appropriate when bulk packaging meets assembly requirements and inventory availability is prioritized. Both parts maintain identical temperature coefficient (±100ppm/°C) and all military-grade certifications.

RN65E4701FB14 (Upgrade Substitute): This part offers improved temperature stability with a temperature coefficient of ±25ppm/°C compared to ±100ppm/°C in the main part, while maintaining all other electrical and mechanical specifications. Selection is appropriate for applications requiring tighter temperature-dependent resistance stability. Packaging format is Bulk. All military-grade certifications and compliance status are maintained.

Both substitute parts are active products with confirmed inventory availability and maintain full compliance with MIL-R-10509/2 military specifications, RoHS non-compliance status, and REACH affected designation consistent with the main part.

Frequently Asked Questions (FAQ)

Q: Can RN65D4701FB14 be used as a direct replacement for RN65D4701FRE6?

A: Yes. The RN65D4701FB14 is electrically and mechanically equivalent. The only difference is packaging format: RN65D4701FRE6 is supplied in Tape & Reel format, while RN65D4701FB14 is supplied in Bulk format. Both parts have identical resistance (4.7 kOhms), tolerance (±1%), power rating (0.5W), temperature coefficient (±100ppm/°C), and physical dimensions (0.180" Dia x 0.562" L).

Q: What is the difference between RN65D4701FB14 and RN65E4701FB14?

A: Both parts are mechanically and electrically identical except for temperature coefficient. RN65D4701FB14 has a temperature coefficient of ±100ppm/°C, while RN65E4701FB14 has ±25ppm/°C. The improved temperature coefficient in RN65E4701FB14 provides better resistance stability across the -65°C to 175°C operating range. Both are supplied in Bulk packaging.

Q: Are all three parts suitable for military applications?

A: Yes. All three parts (RN65D4701FRE6, RN65D4701FB14, and RN65E4701FB14) are manufactured to MIL-R-10509/2 military specification and feature flame retardant coating, moisture resistance, and safety-rated construction. All are active products with confirmed inventory.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Bulk packaging formats do not affect electrical performance. The choice between formats is determined by assembly process requirements and handling preferences.

Q: Are there any compliance differences between the substitute parts?

A: No. All three parts share identical RoHS non-compliance status and REACH affected designation. Compliance status is consistent across all substitutes.

Q: Which substitute should be selected for temperature-sensitive applications?

A: RN65E4701FB14 is the appropriate selection for applications requiring tighter temperature-dependent resistance stability, as it provides a temperature coefficient of ±25ppm/°C compared to ±100ppm/°C in the other two parts.
