Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN65D1003FRE6 is determined by the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 100 kOhms (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.180" Dia × 0.562" L (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Number of terminations: 2 (exact match required)

Allowable Variation Parameters:

• Tolerance: May be equal to or tighter than ±1%
• Power rating: May be equal to or greater than 0.5W
• Temperature coefficient: May be equal to or lower (better stability)
• Packaging format: Cut Tape or Bulk acceptable
• Manufacturer series: RN65 or RN70 base product numbers acceptable

The substitute parts listed maintain all mandatory parameters while offering improvements or alternative packaging in the allowable variation categories.

Parameter Comparison

Engineering Selection Recommendations

RN65C1003FB14: Direct functional equivalent with improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C). Available in bulk packaging. Suitable for applications requiring better temperature stability without tolerance enhancement. All compliance certifications match the main part.

RN65E1003FB14: Direct functional equivalent with superior temperature coefficient (±25ppm/°C). Available in bulk packaging. Recommended for precision applications requiring enhanced thermal stability. Maintains ±1% tolerance specification. All compliance certifications match the main part.

RN65E1003BB14: Enhanced specification variant with tighter tolerance (±0.1% vs. ±1%) and superior temperature coefficient (±25ppm/°C). Available in bulk packaging. Suitable for high-precision measurement and control circuits. All compliance certifications match the main part.

RN70C1003FB14: Higher power rating variant (0.75W vs. 0.5W) with improved temperature coefficient (±50ppm/°C). Available in bulk packaging. Recommended for applications with higher power dissipation requirements or thermal margin requirements. Maintains identical physical dimensions and operating temperature range. All compliance certifications match the main part.

All substitute parts maintain RoHS non-compliant status, REACH affected status, and military-grade construction consistent with the main part.

Frequently Asked Questions (FAQ)

Q: Can RN65E1003BB14 replace RN65D1003FRE6 in all applications?

A: Yes. RN65E1003BB14 maintains all mandatory compatibility parameters (resistance, composition, package type, dimensions, operating temperature range, and terminations). The tighter tolerance (±0.1% vs. ±1%) and lower temperature coefficient (±25ppm/°C vs. ±100ppm/°C) represent improvements that do not create incompatibility. Applications designed for ±1% tolerance will function correctly with ±0.1% components.

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

A: Cut Tape (CT) packaging provides individual components on tape suitable for automated pick-and-place equipment. Bulk packaging provides loose components. Both formats contain identical components; packaging format selection depends on assembly process requirements and handling preferences.

Q: When should RN70C1003FB14 be selected instead of the main part?

A: RN70C1003FB14 should be selected when circuit design requires power dissipation greater than 0.5W or when thermal margin is a design consideration. The 0.75W rating provides 50% additional power capacity. Physical dimensions remain identical, ensuring PCB layout compatibility.

Q: Are all substitute parts military-grade components?

A: Yes. All substitute parts are manufactured to military specifications (MIL-R-10509/2 or MIL-R-10509/3) and feature flame retardant coating, moisture resistance, and safety-rated construction identical to the main part.

Q: What does temperature coefficient indicate?

A: Temperature coefficient (ppm/°C) specifies the fractional change in resistance per degree Celsius of temperature change. Lower values indicate better stability across temperature variations. RN65E1003FB14 and RN65E1003BB14 offer ±25ppm/°C, providing superior stability compared to the main part's ±100ppm/°C specification.
