RN65D3301FRE6 Equivalent & Substitute Parts

Part Overview

The RN65D3301FRE6 is a 3.3 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-rated construction suitable for military and high-reliability applications. The part maintains active product status with 926 units currently in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same resistance value, tolerance, power rating, and package type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN65D3301FRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 3.3 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Series classification: RN65 military-grade (exact match required)

The RN65E3301FB14 qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction between the main part and substitute is the packaging format (Tape & Reel versus Bulk) and temperature coefficient performance (±100ppm/°C versus ±25ppm/°C). Both parts maintain the same base product number (RN65) and comply with MIL-R-10509/2 military specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RN65D3301FRE6 and RN65E3301FB14 maintain active product status and identical compliance classifications (RoHS non-compliant, REACH Affected, ECCN EAR99). Selection between these parts should be based on packaging requirements and procurement logistics. The RN65D3301FRE6 is supplied in Tape & Reel format, suitable for automated assembly processes. The RN65E3301FB14 is supplied in Bulk packaging, appropriate for manual assembly or lower-volume applications. The improved temperature coefficient of the RN65E3301FB14 (±25ppm/°C versus ±100ppm/°C) provides enhanced stability across the operating temperature range, though both parts satisfy the full -65°C to 175°C specification. Component selection should align with assembly methodology and thermal stability requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can RN65E3301FB14 be used as a direct replacement for RN65D3301FRE6?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (3.3 kOhms), tolerance (±1%), power rating (0.5W), composition (metal film), package type (axial), and operating temperature range (-65°C to 175°C). The primary difference is packaging format (Tape & Reel versus Bulk).

Q: What is the significance of the temperature coefficient difference?

A: The RN65E3301FB14 exhibits a temperature coefficient of ±25ppm/°C compared to ±100ppm/°C for the RN65D3301FRE6. This means the substitute part maintains tighter resistance stability across temperature variations. Both coefficients are within acceptable ranges for the specified operating temperature range.

Q: Are there packaging compatibility considerations?

A: Yes. The RN65D3301FRE6 is supplied in Tape & Reel format for automated pick-and-place assembly. The RN65E3301FB14 is supplied in Bulk format, requiring manual handling or alternative assembly methods. Verify that your assembly process accommodates the selected packaging format.

Q: Do both parts meet military specifications?

A: Yes. Both parts are classified under the RN65 series and comply with MIL-R-10509/2 military specifications. Both feature flame retardant coating, moisture resistance, and safety-rated construction.

Q: What is the inventory status for each part?

A: The RN65D3301FRE6 has 926 units in stock. The RN65E3301FB14 has 1406 units in stock. Availability may vary based on procurement timing and supplier allocation.
