Parameter Comparison

Engineering Selection Recommendations

Both RN55C2000FBSL and RN55C2000BB14 are active production components from Vishay Dale, manufactured to identical military specifications (MIL-R-10509/7). Selection between these parts depends on application tolerance requirements:

• RN55C2000FBSL is appropriate for applications where ±1% tolerance meets circuit specifications and standard availability is sufficient.
• RN55C2000BB14 is suitable for precision applications requiring ±0.1% tolerance and offers significantly higher inventory availability (2700 units versus 678 units).

Both parts share identical compliance status (RoHS non-compliant, REACH Affected, ECCN EAR99) and environmental ratings. Physical footprint and thermal characteristics are identical, ensuring direct board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can RN55C2000BB14 replace RN55C2000FBSL in existing designs?

A: Yes. The RN55C2000BB14 maintains identical electrical performance parameters (resistance, power rating, temperature coefficient, operating range) and physical dimensions. The tighter tolerance specification (±0.1% versus ±1%) represents an enhancement rather than a limitation.

Q: Are there any package or footprint differences?

A: No. Both parts use identical axial package construction with dimensions of 0.090" Dia x 0.240" L (2.29mm x 6.10mm). Direct board-level substitution is possible without layout modifications.

Q: What is the significance of the tolerance difference?

A: The RN55C2000BB14 provides ±0.1% tolerance compared to ±1% for the RN55C2000FBSL. This tighter tolerance is beneficial for precision analog circuits, measurement equipment, and applications with strict resistor value requirements. Standard tolerance applications are unaffected by this specification.

Q: Do both parts meet the same military specifications?

A: Yes. Both components are manufactured to MIL-R-10509/7 specification and belong to the RN55 military resistor series. They share identical flame retardant coating, moisture resistance, and safety features.

Q: Is there a compliance difference between these parts?

A: No. Both parts have identical compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8533.21.0090.
