Key Parameters

Substitute Part Grouping Explanation

Substitute and equivalent resistor parts are determined based strictly on identical or superior matches in the following parameters: manufacturer and series, resistance value, power rating, tolerance class (equal or tighter), composition, features, temperature coefficient, operating temperature range, package style, and mechanical size. Only parts matching all these key electrical and mechanical criteria are considered for substitution.

Parameter Comparison

Engineering Selection Recommendations

Both RN55E2500FRE6 and RN55E2500BB14 are active, non-RoHS compliant, and REACH affected. Certificates, environmental statuses, and export classifications are identical. The main difference is the tolerance rating; RN55E2500BB14 provides a tighter tolerance (±0.1%) compared to RN55E2500FRE6 (±1%). All other key parameters, including resistance, form factor, power rating, operating temperature range, and mechanical size, are identical. Packaging differs between parts: RN55E2500FRE6 is supplied in tape & reel; RN55E2500BB14 is supplied in bulk. Selection can be based on required tolerance and packaging format.
