RN65D2001FR36 Equivalent & Substitute Parts

Part Overview

The RN65D2001FR36 is a 2 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 1165 pieces in stock. Equivalent and substitute parts may be required due to packaging availability, inventory constraints, or application-specific performance requirements such as improved temperature coefficient or increased power rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN65D2001FR36 is determined by the following critical parameters: resistance value (2 kOhms), tolerance (±1%), composition (metal film), package type (axial), operating temperature range (-65°C to 175°C), and military-grade specifications. Substitute parts must maintain these core electrical and mechanical characteristics.

The identified substitutes are grouped as follows:

Direct Equivalent (Packaging Variant): RN65D2001FB14 maintains identical electrical specifications and military series designation but differs only in packaging format (bulk versus tape & reel).

Upgraded Substitutes: RN65C2001FB14 and RN70D2001FB14 provide enhanced performance characteristics while maintaining core compatibility. RN65C2001FB14 offers improved temperature coefficient stability (±50ppm/°C versus ±100ppm/°C). RN70D2001FB14 provides increased power rating (0.75W versus 0.5W) while maintaining the same resistance and tolerance, suitable for applications requiring higher power dissipation capacity.

Parameter Comparison

Engineering Selection Recommendations

Selection among the RN65D2001FR36 and its substitutes depends on specific application requirements and availability constraints:

RN65D2001FB14 serves as a direct functional equivalent when bulk packaging is acceptable. This part maintains identical electrical performance and military compliance while offering higher inventory availability (1363 pieces).

RN65C2001FB14 is suitable for applications requiring enhanced temperature stability. The reduced temperature coefficient (±50ppm/°C) provides improved accuracy over wider temperature ranges compared to the main part specification (±100ppm/°C). This upgrade maintains all other electrical and mechanical parameters.

RN70D2001FB14 is appropriate for circuits requiring higher power dissipation. The increased 0.75W rating accommodates applications where the 0.5W specification of the main part presents thermal limitations. This part operates within the same temperature range and maintains identical resistance and tolerance specifications.

All substitute parts maintain active product status, military-grade specifications, and compliance with REACH and EAR99 classifications consistent with the main part.

Frequently Asked Questions (FAQ)

Q: Can RN65D2001FB14 be used as a direct replacement for RN65D2001FR36?

A: Yes. RN65D2001FB14 is electrically and mechanically identical to RN65D2001FR36. The only difference is packaging format: RN65D2001FR36 is supplied in tape & reel format while RN65D2001FB14 is supplied in bulk. Both maintain the same 2 kOhms resistance, ±1% tolerance, 0.5W power rating, and military specifications.

Q: What is the difference between RN65C2001FB14 and RN65D2001FR36?

A: RN65C2001FB14 offers improved temperature coefficient performance at ±50ppm/°C compared to RN65D2001FR36 at ±100ppm/°C. All other parameters including resistance, tolerance, power rating, operating temperature range, and package type remain identical. This makes RN65C2001FB14 suitable for precision applications requiring tighter temperature stability.

Q: When should RN70D2001FB14 be selected instead of RN65D2001FR36?

A: RN70D2001FB14 should be selected when the application requires power dissipation exceeding 0.5W. RN70D2001FB14 is rated at 0.75W while maintaining the same 2 kOhms resistance and ±1% tolerance. The RN70 series (MIL-R-10509/3) is the higher power variant of the RN65 series (MIL-R-10509/2).

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

A: Yes. All listed substitutes maintain identical axial package dimensions of 0.180" diameter by 0.562" length (4.57mm x 14.27mm). PCB footprints designed for RN65D2001FR36 accommodate all substitute parts without modification.

Q: Do the substitute parts meet the same military and compliance standards?

A: Yes. All substitute parts are manufactured by Vishay Dale under military-grade specifications (MIL-R-10509 series), feature flame retardant coating, moisture resistance, and safety certification. All parts maintain REACH compliance and EAR99 classification consistent with the main part.

Q: What is the difference between tape & reel and bulk packaging?

A: Tape & reel packaging (RN65D2001FR36) is designed for automated assembly processes and component handling equipment. Bulk packaging (RN65D2001FB14, RN65C2001FB14, RN70D2001FB14) is suitable for manual assembly or when automated equipment is not required. Electrical and mechanical specifications are identical between packaging formats.
