Key Parameters

Substitute Part Grouping Explanation

The Ohmite 40F35KE qualifies as a parametric equivalent to the 40F35K based on identical electrical and mechanical specifications. Both parts share the same resistance value (35 kOhms), tolerance (±1%), power rating (10W), composition (wirewound), package type (axial), temperature coefficient (±20ppm/°C), physical dimensions (0.406" Dia x 1.902" L), and termination count (2). The primary distinction between these parts is packaging format and RoHS compliance status. Substitution is valid when these differences align with application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 40F35K and 40F35KE are Active status components suitable for direct substitution based on electrical and mechanical parameters. The 40F35KE offers ROHS3 compliance, making it the appropriate selection for applications subject to RoHS regulations or customer requirements mandating compliant materials. The 40F35K remains suitable for applications without RoHS compliance requirements. Packaging format differences (standard versus bulk) reflect distribution and procurement considerations rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can the 40F35KE replace the 40F35K in existing designs? A: Yes. Both parts are electrically and mechanically identical, sharing the same resistance value, tolerance, power rating, composition, package type, temperature coefficient, and physical dimensions. Selection between them depends on RoHS compliance requirements and packaging format preferences.

Q: What is the primary difference between these two parts? A: The 40F35KE is ROHS3 compliant, while the 40F35K is RoHS non-compliant. Both parts are packaged in axial format, with the 40F35KE supplied in bulk packaging and the 40F35K in standard packaging.

Q: Are the physical dimensions identical? A: Yes. Both parts measure 0.406" diameter by 1.902" length (10.30mm x 48.30mm), ensuring identical PCB layout and mechanical fit.

Q: Which part should be selected for new designs? A: Selection is based on regulatory and compliance requirements. For applications requiring RoHS compliance, specify the 40F35KE. For applications without RoHS mandates, either part is acceptable based on availability and packaging requirements.

Q: Do these parts have identical electrical performance? A: Yes. Both parts share identical resistance value (35 kOhms), tolerance (±1%), power rating (10W), temperature coefficient (±20ppm/°C), and composition (wirewound), ensuring equivalent electrical performance in circuit applications.
