Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN65C1503FRE6 is determined by the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 150 kOhms
• Tolerance: ±1%
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -65°C to 175°C

Mechanical Parameters (Must Match):

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

Allowable Variation:

• Power rating: May be equal or higher than 0.5W (1/2W)

Compliance Parameters (Must Match):

• Composition: Metal Film
• Features: Flame Retardant Coating, Military, Moisture Resistant, Safety
• Military specification compliance: MIL-R-10509 series

The RN70C1503FB14 qualifies as a substitute because it maintains all electrical parameters, mechanical compatibility, and military specification compliance while providing an upgraded power rating of 0.75W (3/4W).

Parameter Comparison

Engineering Selection Recommendations

The RN70C1503FB14 is a direct substitute for the RN65C1503FRE6 in applications where the following conditions are met:

1. Electrical Compatibility: Both components maintain identical resistance (150 kOhms), tolerance (±1%), and temperature coefficient (±50ppm/°C) specifications, ensuring equivalent circuit performance.

2. Thermal Performance: The identical operating temperature range (-65°C to 175°C) and temperature coefficient ensure thermal stability across all specified operating conditions.

3. Mechanical Fit: Axial package configuration and physical dimensions (0.180" Dia x 0.562" L) are identical, permitting direct board-level substitution without layout modifications.

4. Military Compliance: Both components comply with MIL-R-10509 military specification standards with flame retardant coating, moisture resistance, and safety features maintained.

5. Power Margin: The RN70C1503FB14 provides a 0.25W power rating increase (0.75W versus 0.5W), offering enhanced thermal margin in power-dissipation-sensitive applications.

6. Regulatory Status: Both components share identical RoHS non-compliance and REACH-affected status, maintaining consistent regulatory posture.

Frequently Asked Questions (FAQ)

Q: Can the RN70C1503FB14 be used as a direct replacement for the RN65C1503FRE6?

A: Yes. The RN70C1503FB14 maintains all critical electrical parameters (resistance, tolerance, temperature coefficient, operating temperature range) and mechanical specifications (axial package, identical dimensions) required for direct substitution. The higher power rating (0.75W versus 0.5W) provides additional thermal margin without affecting circuit operation.

Q: What is the difference between the RN65 and RN70 series?

A: The primary difference is the power rating. The RN65 series is rated at 0.5W (1/2W), while the RN70 series is rated at 0.75W (3/4W). Both series comply with MIL-R-10509 military specifications and share identical electrical characteristics and physical dimensions for the 150 kOhms ±1% value.

Q: Are there any packaging differences between these parts?

A: The RN65C1503FRE6 is supplied in Tape & Reel (TR) packaging, while the RN70C1503FB14 is supplied in Bulk packaging. Both use identical axial through-hole package configuration with the same physical dimensions (0.180" Dia x 0.562" L). Packaging format does not affect component performance or board-level compatibility.

Q: Will substituting the RN70C1503FB14 affect circuit performance?

A: No. The RN70C1503FB14 maintains identical electrical specifications including resistance value, tolerance, temperature coefficient, and operating temperature range. The increased power rating does not alter electrical performance in the circuit.

Q: Are both components suitable for military applications?

A: Yes. Both the RN65C1503FRE6 and RN70C1503FB14 comply with MIL-R-10509 military specifications and include flame retardant coating, moisture resistance, and safety features required for military-grade applications.

Q: What is the temperature coefficient significance?

A: Both components share an identical temperature coefficient of ±50ppm/°C, ensuring that resistance variation across the -65°C to 175°C operating range remains consistent and predictable for precision circuit applications.
