Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on matching the following allowed electrical and mechanical parameters: resistance value (82.5 kOhms), tolerance (±1%), power rating (0.5W, 1/2W), composition (metal film), flame retardant or safety features, temperature coefficient (±50ppm/°C), package/case type (axial), number of terminations (2), and compliance status (RoHS/REACH/ECCN/HTSUS). Substitute parts must have the same or equivalent parameter values, ensuring compatibility within the through-hole axial resistor category.

Parameter Comparison

Engineering Selection Recommendations

Both RNF12FTC82K5 and CMF5582K500FHEB are listed as active and are ROHS3 compliant, with REACH unaffected status and ECCN EAR99 classification. Approved substitute parts possess equivalent certifications and regulatory compliance as the main part number, supporting direct substitution where these criteria are prioritized for through-hole axial resistor applications.

Frequently Asked Questions (FAQ)

Q1: What are the primary electrical parameters that must match when substituting through-hole axial resistors like RNF12FTC82K5?
A1: Resistance, tolerance, power rating, composition, temperature coefficient, and features must be equivalent for substitution within this resistor category.

Q2: Are packaging or inventory differences allowed in substitution logic?
A2: Product packaging (Tape & Reel, Cut Tape) is a logistical consideration and does not impact the core electrical and mechanical compatibility for the specified parameters.

Q3: Do compliance certifications affect substitution eligibility?
A3: Substitute parts must match RoHS, REACH, and ECCN compliance statuses provided for the main part to ensure regulatory conformity.

Q4: Is physical size/dimension a mandatory match for axial resistors?
A4: Size/dimension must be considered if mechanical fit or board layout is critical; substitution within the axial category is based on equivalent functional and electrical parameters provided.

Q5: What packaging/case requirements are specified?
A5: The package/case must be axial, with two terminations, to ensure compatibility in through-hole applications as specified for both main and substitute resistor parts.
