Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN65C2002FBSL is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 20 kOhms (exact match required)
• Power rating: 0.5W (1/2W)
• Package type: Axial
• Composition: Metal Film
• Physical dimensions: 0.180" Dia × 0.562" L
• Operating temperature range: -65°C to 175°C
• Series classification: Military, MIL-R-10509/2, RN65
• Features: Flame Retardant Coating, Military, Moisture Resistant, Safety

Allowable Variation:

• Tolerance: May be tighter (lower tolerance value) than the original specification without affecting circuit compatibility

The RN65C2002BB14 qualifies as a direct substitute based on identical electrical characteristics, mechanical compatibility, and environmental specifications. The tolerance upgrade from ±1% to ±0.1% represents an enhancement that does not compromise interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the RN65C2002FBSL and RN65C2002BB14 maintain active product status with current manufacturing and inventory support. Selection between these parts is based on tolerance requirements:

• RN65C2002FBSL is appropriate for applications where ±1% tolerance meets circuit specifications and cost optimization is a priority.
• RN65C2002BB14 is appropriate for applications requiring tighter tolerance control at ±0.1%, providing enhanced precision in voltage divider networks, precision instrumentation, or high-accuracy analog circuits.

Both parts comply with MIL-R-10509/2 military specifications and carry identical environmental certifications (RoHS non-compliant, REACH Affected, ECCN EAR99). Physical footprint and thermal characteristics are identical, ensuring direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can RN65C2002BB14 replace RN65C2002FBSL in existing designs?

A: Yes. The RN65C2002BB14 is a direct mechanical and electrical substitute. The tighter tolerance (±0.1% versus ±1%) represents an enhancement that does not degrade circuit performance. No board layout or schematic modifications are required.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. RN65C2002FBSL carries ±1% tolerance, while RN65C2002BB14 carries ±0.1% tolerance. All other electrical, mechanical, and environmental parameters are identical.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts use identical axial package configuration with dimensions of 0.180" Dia × 0.562" L (4.57mm × 14.27mm). They are pin-compatible and footprint-compatible for through-hole PCB assembly.

Q: Do these parts meet military specifications?

A: Yes. Both parts are certified to MIL-R-10509/2 standard and are classified as military-grade components within the RN65 series. Both feature flame retardant coating, moisture resistance, and safety certification.

Q: What is the temperature operating range for both parts?

A: Both parts operate across the identical temperature range of -65°C to 175°C with a temperature coefficient of ±50ppm/°C.

Q: Can I use RN65C2002FBSL as a substitute for RN65C2002BB14?

A: No. RN65C2002FBSL has a wider tolerance (±1%) compared to RN65C2002BB14 (±0.1%). Applications requiring ±0.1% tolerance cannot accept the looser tolerance of the FBSL variant.
