Substitute Part Grouping Explanation

Substitute parts for the 45F22K are identified based on electrical and mechanical parameter equivalence. The primary substitution criterion is parametric matching across resistance value, tolerance, power rating, composition type, and physical package configuration. The 45F22KE qualifies as a parametric equivalent because it maintains identical electrical specifications (22 kOhms ±1% 5W wirewound) and mechanical dimensions (0.343" Dia x 0.937" L). The distinction between these part numbers relates to packaging format and compliance certification status rather than functional performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 45F22K and 45F22KE are active production components from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and packaging format. The 45F22KE offers ROHS3 compliance, making it suitable for applications subject to RoHS3 regulatory requirements. The 45F22K is RoHS non-compliant and appropriate for applications without such restrictions. Both parts maintain REACH Unaffected status and EAR99 export classification. Inventory availability and procurement lead times may also influence part selection.

Frequently Asked Questions (FAQ)

Q: Can the 45F22KE be used as a direct replacement for the 45F22K?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (22 kOhms ±1%), tolerance (±1%), power rating (5W), composition (wirewound), and physical dimensions (0.343" Dia x 0.937" L). The primary difference is RoHS compliance status and packaging format.

Q: What is the difference between the 45F22K and 45F22KE?
