Equivalent & Substitute Parts for RN65C1501FRE6

Part Overview

The RN65C1501FRE6 is a 1.5 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 maintains active product status with 830 units currently in stock.

Substitute parts become necessary when design requirements demand higher power dissipation capability, alternative packaging formats, or when primary part availability is constrained. The RN70C1501FB14 provides an upgrade path for applications requiring increased thermal performance while maintaining electrical equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN65C1501FRE6 is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 1.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)

Mechanical Compatibility:

• Package type: Axial (exact match required)
• Physical dimensions: 0.180" Dia x 0.562" L (4.57mm x 14.27mm) (exact match required)
• Number of terminations: 2 (exact match required)

Functional Upgrade Criteria:

• Power rating: May be equal or higher than 0.5W
• Composition: Metal Film (exact match required)
• Military classification and certifications: Must maintain or exceed original specifications

The RN70C1501FB14 qualifies as a direct substitute because it maintains all electrical parameters, mechanical dimensions, and composition while providing increased power dissipation (0.75W vs. 0.5W), making it suitable for applications with higher thermal demands.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (RN65C1501FRE6): Select the RN65C1501FRE6 when circuit design specifies a 0.5W power dissipation requirement and board space is optimized for the RN65 series footprint. Both parts maintain identical physical dimensions and electrical characteristics, ensuring direct PCB compatibility.

Substitute Part Selection (RN70C1501FB14): Select the RN70C1501FB14 when thermal analysis indicates power dissipation exceeding 0.5W or when design margins require higher power rating capability. The increased 0.75W rating provides additional thermal headroom while maintaining all electrical and mechanical specifications. Both parts retain active product status and military-grade certifications.

Compliance Considerations: Both parts are RoHS non-compliant and REACH Affected. Verify compliance requirements for your specific application before final component selection. Both parts maintain military classification under MIL-R-10509 standards and are suitable for high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can RN70C1501FB14 be used as a direct replacement for RN65C1501FRE6? A: Yes. The RN70C1501FB14 is electrically and mechanically equivalent to the RN65C1501FRE6. Both parts share identical resistance (1.5 kOhms), tolerance (±1%), temperature coefficient (±50ppm/°C), operating temperature range (-65°C to 175°C), physical dimensions (0.180" Dia x 0.562" L), and axial package configuration. The RN70 series provides higher power rating (0.75W vs. 0.5W), making it suitable for applications with increased thermal demands.

Q: What are the key differences between RN65C1501FRE6 and RN70C1501FB14? A: The primary differences are power rating (0.5W vs. 0.75W), series designation (RN65 vs. RN70), MIL-R-10509 classification level (2 vs. 3), and packaging format (Tape & Reel vs. Bulk). All other electrical and mechanical parameters remain identical.

Q: Are both parts suitable for military applications? A: Yes. Both RN65C1501FRE6 and RN70C1501FB14 are military-grade components classified under MIL-R-10509 standards with flame retardant coating, moisture resistance, and safety features. Both maintain active product status.

Q: What is the impact of packaging format differences? A: RN65C1501FRE6 is supplied in Tape & Reel (TR) format, while RN70C1501FB14 is supplied in Bulk format. This affects procurement and handling procedures but does not impact electrical or mechanical performance. Verify packaging requirements for your assembly process.

Q: Can these parts be used interchangeably in existing designs? A: Yes, provided the circuit design accommodates the higher power rating of the RN70C1501FB14. No PCB layout modifications are required due to identical physical dimensions and axial package configuration. Verify that your application does not have specific power rating constraints that would preclude the use of the higher-rated substitute.
