RN65D1821FRE6 Equivalent & Substitute Parts

Part Overview

The RN65D1821FRE6 is a 1.82 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. The part is currently active in production with 906 units in stock. Substitute parts may be required due to packaging availability, supply chain constraints, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the RN65D1821FRE6 is determined by strict equivalence across the following parameters:

• Resistance value: 1.82 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 175°C
• Package configuration: Axial
• Physical dimensions: 0.180" Dia × 0.562" L
• Series compliance: RN65 military-grade per MIL-R-10509/2
• Features: Flame Retardant Coating, Military, Moisture Resistant, Safety

The primary distinction between the main part and its substitute is packaging format: the RN65D1821FRE6 is supplied in Tape & Reel (TR) configuration, while the substitute RN65D1821FB14 is supplied in Bulk packaging. All electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the RN65D1821FRE6 and RN65D1821FB14 are active production components manufactured by Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on procurement and assembly requirements:

The RN65D1821FRE6 in Tape & Reel packaging is suitable for automated assembly processes and high-volume production environments where component feeding and placement automation are utilized.

The RN65D1821FB14 in Bulk packaging is suitable for manual assembly, low-volume production, or applications where tape-and-reel format is not required.

Both parts maintain compliance with military-grade MIL-R-10509/2 specifications and carry identical RoHS non-compliant and REACH Affected designations. No electrical performance difference exists between the two configurations.

Frequently Asked Questions (FAQ)

Q: Can RN65D1821FB14 be used as a direct replacement for RN65D1821FRE6?

A: Yes. The RN65D1821FB14 is electrically and mechanically identical to the RN65D1821FRE6. The only difference is packaging format: Bulk versus Tape & Reel. Both parts deliver the same 1.82 kOhms ±1% resistance, 0.5W power rating, and military-grade performance specifications.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel (TR) packaging supplies components wound on continuous tape within a reel, designed for automated pick-and-place assembly equipment. Bulk packaging supplies loose components in quantities suitable for manual handling and assembly. Electrical and mechanical performance are identical.

Q: Are there any compliance differences between these parts?

A: No. Both parts share identical RoHS non-compliant and REACH Affected designations. Both comply with MIL-R-10509/2 military specifications and carry the same flame retardant, moisture-resistant, and safety-rated features.

Q: What determines substitution eligibility for the RN65D1821FRE6?

A: Substitution is determined by matching resistance value (1.82 kOhms), tolerance (±1%), power rating (0.5W), composition (Metal Film), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 175°C), axial package configuration, and physical dimensions (0.180" Dia × 0.562" L). Packaging format may differ without affecting electrical performance.

Q: Can I use a different resistance value or tolerance as a substitute?

A: No. Resistance value and tolerance are critical electrical parameters. Only parts with identical 1.82 kOhms ±1% specifications are substitutes for the RN65D1821FRE6.
