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

The identified substitute part RN65D4021FB14 maintains identical electrical and mechanical specifications. The only difference is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Bulk packaging. Both parts are manufactured by Vishay Dale under the same military series designation and share all functional and environmental characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both RN65D4021FRE6 and RN65D4021FB14 are active production components manufactured by Vishay Dale with identical electrical performance and environmental ratings. Selection between these parts should be based on packaging requirements and supply chain considerations:

RN65D4021FRE6 is appropriate for automated assembly processes requiring tape and reel packaging, which provides component feeding compatibility with standard pick-and-place equipment.

RN65D4021FB14 is appropriate for manual assembly, kit builds, or applications where bulk packaging is preferred. Higher current inventory (1039 units versus 747 units) may provide supply advantage.

Both parts carry identical compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, HTSUS 8533.21.0090. Military series designation (MIL-R-10509/2) and all performance characteristics remain constant across both part numbers.

Frequently Asked Questions (FAQ)

Q: Can RN65D4021FB14 be used as a direct replacement for RN65D4021FRE6 in circuit design?
