Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WHB150FE is determined by matching the following critical parameters: resistance value (150 Ohms), tolerance (±1%), power rating (1W), composition (wirewound), package type (axial), and temperature coefficient (±20ppm/°C). All identified substitutes maintain these core electrical and mechanical specifications, ensuring functional equivalence in circuit applications.

The WHB150FET qualifies as a direct substitute, differing only in packaging format (Tape & Reel versus bulk) and the addition of non-inductive construction. The 41F150E qualifies as a manufacturer-recommended substitute, with identical electrical parameters but extended operating temperature range (-55°C ~ 275°C) and different physical dimensions due to silicone coating construction.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and RoHS compliance, confirming their suitability for current design applications. The WHB150FET provides identical electrical and dimensional specifications to the WHB150FE, with the distinction of non-inductive construction and Tape & Reel packaging, making it suitable for automated assembly processes. The 41F150E offers extended operating temperature capability to 275°C and silicone coating construction, with larger physical dimensions that must be verified for PCB layout compatibility. Selection between these substitutes depends on specific application requirements regarding temperature range, assembly method, and available board space.

Frequently Asked Questions (FAQ)

Q: Can WHB150FET be used as a direct replacement for WHB150FE in existing designs? A: Yes. Both parts share identical resistance (150 Ohms), tolerance (±1%), power rating (1W), temperature coefficient (±20ppm/°C), and physical dimensions (0.130" Dia x 0.276" L). The primary difference is packaging format (Tape & Reel versus bulk) and non-inductive construction in the WHB150FET.

Q: What are the dimensional constraints when substituting with 41F150E? A: The 41F150E has larger dimensions (0.126" Dia x 0.437" L) compared to WHB150FE (0.130" Dia x 0.276" L). PCB layout and component spacing must be verified before substitution to ensure mechanical fit.

Q: Is the extended temperature range of 41F150E (-55°C ~ 275°C) a functional advantage? A: The extended range is available if the application requires operation above 150°C. For applications within the -55°C ~ 150°C range, all three parts are functionally equivalent.

Q: Are all substitute parts RoHS compliant? A: Yes. WHB150FE is RoHS3 Compliant, while WHB150FET and 41F150E are RoHS Compliant, meeting current environmental regulations.

Q: What is the significance of non-inductive construction in WHB150FET? A: Non-inductive wirewound construction reduces parasitic inductance, beneficial for high-frequency applications. Standard wirewound construction in WHB150FE and 41F150E is suitable for general-purpose applications.
