Parameter Comparison

Engineering Selection Recommendations

Both the RN60C1801CBSL and RN60E1801BB14 maintain active product status with identical regulatory compliance profiles. Selection between these parts depends on application tolerance requirements:

The RN60C1801CBSL is suitable for applications where ±0.25% tolerance and ±50ppm/°C temperature coefficient meet circuit specifications.

The RN60E1801BB14 is appropriate for applications requiring tighter tolerance control at ±0.1% and improved thermal stability at ±25ppm/°C. Both components share identical RoHS non-compliant and REACH Affected status, ensuring consistent supply chain compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can RN60E1801BB14 directly replace RN60C1801CBSL in existing designs?

A: Yes. Both parts share identical resistance value (1.8 kOhms), power rating (0.25W), package type (Axial), physical dimensions (0.145" Dia x 0.344" L), and operating temperature range (-65°C to 175°C). The RN60E1801BB14 provides enhanced tolerance (±0.1% vs ±0.25%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct mechanical and electrical substitute.

Q: What are the key differences between these two parts?

A: The primary differences are tolerance specification and temperature coefficient. RN60E1801BB14 offers ±0.1% tolerance compared to RN60C1801CBSL at ±0.25%, and a temperature coefficient of ±25ppm/°C versus ±50ppm/°C. All other electrical and mechanical parameters remain identical.

Q: Are both parts military-grade components?

A: Yes. Both RN60C1801CBSL and RN60E1801BB14 are classified as military-grade resistors compliant with MIL-R-10509/1 specifications and feature flame retardant coating, moisture resistance, and safety construction.

Q: Do these parts have identical physical dimensions?

A: Yes. Both components measure 0.145" diameter by 0.344" length (3.68mm x 8.74mm) in axial package configuration, ensuring identical PCB footprint and mounting compatibility.

Q: What is the regulatory compliance status for both parts?

A: Both parts are RoHS non-compliant and REACH Affected. Regulatory documentation requirements remain consistent between the two components.
