Substitute Part Grouping Explanation

Substitute parts for the 40F2K0E are identified based on strict equivalence across the following critical parameters:

  • Resistance value: 2 kOhms
  • Tolerance: ±1%
  • Power rating: 10W
  • Composition: Wirewound
  • Package type: Axial
  • Temperature coefficient: ±20ppm/°C
  • Physical dimensions: 0.406" Dia x 1.902" L (10.30mm x 48.30mm)
  • Termination count: 2

The Ohmite 40F2K0 meets all electrical and mechanical equivalence criteria. Differences in product compliance certifications and packaging specifications do not affect functional interchangeability in applications where the core electrical and mechanical parameters are the determining factors.

Engineering Selection Recommendations

The 40F2K0E is the preferred selection for applications requiring RoHS3 compliance and confirmed REACH unaffected status. The 40F2K0 substitute provides electrical and mechanical equivalence but does not meet RoHS3 compliance requirements and has undefined REACH status. Selection between these parts depends on regulatory and compliance requirements of the end application. Both parts maintain identical electrical performance characteristics and physical form factor.

Frequently Asked Questions (FAQ)

Q: Can the 40F2K0 be used as a direct replacement for the 40F2K0E?

A: The 40F2K0 is electrically and mechanically equivalent to the 40F2K0E. Both components share identical resistance value, tolerance, power rating, wirewound composition, axial package type, temperature coefficient, and physical dimensions. Substitution is valid from a functional standpoint. Compliance requirements must be evaluated independently based on application specifications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by equivalence in resistance value (2 kOhms), tolerance (±1%), power rating (10W), composition (wirewound), package type (axial), temperature coefficient (±20ppm/°C), and physical dimensions (0.406" Dia x 1.902" L). All substitute parts must match these parameters exactly.

Q: Are there differences in packaging between the 40F2K0E and 40F2K0?

A: The 40F2K0E is supplied in bulk packaging. The 40F2K0 packaging specification is not defined in the available data. Physical component dimensions and form factor remain identical between both parts.

Q: What compliance differences exist between these parts?

A: The 40F2K0E is RoHS3 compliant and REACH unaffected. The 40F2K0 is RoHS non-compliant with vendor-undefined REACH status. Applications subject to RoHS3 or REACH regulations must use the 40F2K0E.
